A suite of useful Javascript plugins and functions to help with Front-end Development on websites
A suite of useful Javascript plugins and functions to help with front-end development on websites. Instead of searching for unconnected plugins that may not work together well, this suite is to help remedy that. It's not to solve every problem with front-end web development, but the most common. The scripting features plugins for collapsible sections, popups, parallaxing elements, tabs and more. It features utilities for setting and getting cookies, smooth scrolling (without jQuery, or with CSS), throttled resizing, querystring parameter filtering and more. The plugin's are meant to be configurable and consistent. This scripting is designed to be imported in easily so you can start building!
These are made to work with Cash (with jQuery still an option) as the only dependency. Cash is a small jQuery alternative that give developers DOM traversing without the extra bloat. In my opinion, having a DOM traversing Library is essential. Also, everybody who's done any web developement is familiar with jQuery syntax.
Combined all together its ~ 60k. Add that with Cash and its less than jQuery alone!
data- attributeThe data attribute is always the data- (of course) and then the plugin name pluginName followed by -options.
For Example: all have options that can be plugged in as a data attribute, in object literal format.
<div id="your-plugin-elem" data-pluginName-options="{option:'text',option2: true, etc: 'you get the idea'}"></div>
Once initialized, each plugin when re-accessed (when not 'removed') will only get updates to their parameters. Could come in handy for instance when you have an accordion (or collapsible section) and on mobile you want it to scroll to the top on open (that plugin does that!), but not on desktop. This works for the vast majority of params, but not all FYI. For example, I can specify a 'click' event and that can only be set on 'init'. Perhaps I'll document this later on though.
$('.your-plugin-elem').PluginOfSorts({change:'yep', height: 1e6})
Lots of callback functions to run after and before events and such that may help you out when you need it most.
Most of these scripts all work back to IE11. There should be some polyfilling needed for this "retired" browser, that may still be a requirement for some of you out there.

Styles are located in the src/assets/scss/ directory and all can be grabbed that way and added on in. Still should do a little more work in updating the SCSS variables to be frank. So I would just drag those files into the project directly. The SCSS should be pretty minimal and generic so it'll more easily take on custom styling.
Adds tabbing, allows the use of arrows for toggling around the navigation, which is configurable depending on the menu design. The use of the escape key to go up a level. View
It's is for toggling collapsible sections. Can be used like an accordion and etc. View
When Flexbox, or other options won’t work, use this to equalize content View Equalize Content
Load background images and images lazily once they appear in the viewport! Also, run custom fuctions as well to hook into elements appearing (or disappearing) as well. This plugin uses window.IntersectionObserver API.
View Lazy Load
This is a more minimalistic version of the 'popup' plugin. Nice bit of flexibility do things like image carousels, confirm prompts and such with just a little peppering of custom code. View Modal
This plugin just adds a delay to the desktop navigation for the nestled levels of a <ul>. Also, features an edge detection on the drop-downs, and uses corresponding CSS to position, so it stays on the page.
View Navigation Desktop
Neat little mobile navigation plugin View Navigation Mobile
For making a parallaxing elements on the page. Lots of configurable options. View Parallax Elements
Enhance a selectbox View Select Enhance
Tabs in tabs, change onhashchange this does it for tabs! View Tabs
Each plugin can be removed by calling $('.plugin-selector').plugin('remove'), and it'll call the static method to remove it and all its components. Or if you want it can be stored as a method $.plugin.remove($('.plugin-selector').eq(1)) or $.plugin.remove('.plugin-selector') and done that way.
LibraryExtendEach class just needs to have the following properties set on it
class YourClass {
static get version() {
return VERSION;
}
static get pluginName() {
//Data Name is `YourClass`
return DATA_NAME;
}
static remove() {
//... remove operations ridding of data stored
// and any associated events
}
constructor(element, options, index){
//... your constructor
}
}
First parameter can be one Plugin, or an array of them. Pass in the second param which will notify the user of updated parameters (good for development).
// the third option 'Lib' allows a user to pass in either
// jQuery or Cash library to extend the plugin's to.
libraryExtend(plugins:Array<Plugin> | Plugin, notify?:boolean, Lib: $)
If using Cash and installing plugins into the library, this function needs to be run to install $.store, which is used internally on all the plugins. If using jQuery this can be ignored as it'll use $.fn.data to store instances of plugins and their parameters.
Pass in the first attribute to add in the expose method, which allows you to see all the data stored in the Map.
installStoreToLibrary(expose?:boolean)
Inside the $.store method is the following structure. The first parameter can be an HTMLElement or a $(HTMLElement). The second parameter is a string and is the identifier on on which the data is stored. Multiple properties can be stored on the same element. In the plugin's the instance (PluginName_instance) is saved, as well as the instance paremeters (PluginName_params).
const Store = {
set(element, keyStore, data) {
mapData.set(element, keyStore, data)
},
get(element, keyStore) {
return mapData.get(element, keyStore)
},
remove(element, keyStore) {
mapData.delete(element, keyStore)
},
//console logs the all the data stored in the Map
//which could be helpful if developing.
//only added if the first parameter is set to true in the function
expose(){
mapData.expose()
}
};
If using jQuery and you have plugins that use $.fn.data and $.fn.removeData this can alternatively be used to map over the Cash Dom's built-in data method. The data retrieval for data-attrs is the same pulling the first occurance on the same items queried. It first checks the data stored in the Store.
installStoreAsDataToLibrary(expose?:boolean)
formInputs function currently adds in space-bar support for radio buttons, and checkbox inputs. As long as there is a for attribute on a <label> that maps to an input.
formInputs.init();
First parameter is the HTMLElement's top to scroll to position top, the second is the speed. Default speed is 100. This uses the window.scroll so should work cross-browser. This stops scrolling if the previous pixel is the same as the next, if the scroll tries to get broken, or if it can't scroll to anymore. Third argument is a callback function to run after the scrolling is done. The 4th parameter is the arguments for that function if necessary.
smoothScroll(scrollToTop :number ,speed?: number , afterScroll?:Function, afterScrollArgs?:Array<any>);
Getting and setting cookies made easy!
params
| Option | Description |
|---|---|
| path | path to the cookie, default is the current location.pathname. |
| expires | set in minutes. Time the cookie will expire. |
| secure | if it can only be accessed via https. This gets set automatically when sameSite is set to None. |
| sameSite | Lax, Strict or None are the options. |
//setting a cookie
cookies.set('cookieName','your cookie value',{path:'/',expires: 60, secure: true, sameSite: 'Lax'});
//getting a cookie
cookies.get('cookieName',{path: '/'});
//removing a cookie
cookies.remove('cookieName',{path:'/path/to-your/cookie'});
//maybe you want to extend $ ?
$.extend({cookies: cookies});
Searches for a query-string value using location.hash.
getHashParam(search:string)
Searches for a query-string value using location.search, pass in an optional second parameter to search another string for key-pair values.
getUrlParam(search:string ,searchString?:string)
This is used in the Popup and NavMobile plugin's, to trap the focus of tabbing events to just the availble focusable elements. Each tab it re-takes inventory on what is available to tab to, so you can load dynamic/change content that may not be available when the focus trap is created.
params
| Option | Type | Default | Description |
|---|---|---|---|
| focusFirst | boolean | true | Focus's the first element |
| nameSpace | string | 'trapFocus' | Unique namespace for the tabbing keydown event. |
| focusableElements | string or array | ['button', 'a', 'input', 'select', 'textarea', '[tabindex]'] | A listing of focusable elements. |
const trappedFocus = trapFocus(element:JQuery<HTMLElement> | HTMLElement, params?: PlainObject);
// to remove later on
trappedFocus.remove();
This plugin allows a user to use the keyboard arrows to navigate a desktop navigation, and are configurable depending on the design. It also allows the use of the escape key to go up a level in the navigation.
| Option | Type | Default | Description |
|---|---|---|---|
| keyDirections | array | ['horizontal', 'vertical', 'vertical'] | The direction in which the menu appears. For example, 'horizontal' means the <li> elements are going across the page. The next in the array is 'vertical', which means they're stacked. Typically if a third level exists they're also vertical as well. |
| focusCss | string | 'focus' | the focus class that allows the menu to appear as being active |
| focusLeaveElems | string | 'a, [tabindex], select, button' | listing of options to focus on to escape the last nav item via the arrow keys |
The following structure should be used with this plugin:
HTML
<nav id="main-menu">
<ul>
<li><a href="#level-1-link">Level 1 Link</a></li>
<li><a href="#level-1-link">Level 1 Link</a>
<ul>
<li><a href="#level-2-link">Level 2 Link</a></li>
<li><a href="#level-2-link">Level 2 Link</a></li>
</ul>
</li>
<li><a href="#healthy-choice">Level 1 Link</a></li>
<ul>
<li><a href="#level-2-link">Level 2 Link</a></li>
<li><a href="#level-2-link">Level 2 Link</a></li>
<li><a href="#level-2-link">Level 2 Link</a></li>
</ul>
</li>
</ul>
</nav>
$('#main-menu').accessibleMenu({
keyDirections: ['horizontal', 'vertical', 'vertical'],
focusCss: 'focus'
});
This has a move-to-top after open feature, open with location hash, and callbacks after events and such.
| Option | Type | Default | Description |
|---|---|---|---|
| cssPrefix | string | 'collapse' | CSS class name for styling purposes that is used as prefix to all other classes (btn, body, etc). |
| toggleClickBindOn | string | 'group' | Attaches the click to the selector or $('.your-selector').colla..., other option is 'body' and it'll then be set on the body. Can come in handy, I had a use-case for it, forgot exactly why. |
| toggleDuration | number | 500 | The speed at which the items will open, should pair with CSS transition settings. |
| toggleGroup | boolean | false | More or less toggles the other opened element(s) closed, and make it behave like an accordion. |
| moveToTopOnOpen | boolean | false | After the element is opened, the item will move to the top of it. Good for mobile. |
| moveToTopOffset | number | 0 | Should we need to offset the move to the top if the moveToTopOnOpen is set to true. |
| scrollSpeed | number | 100 | The speed of the scroll if moveToTopOnOpen is set to true. |
| useHashFilter | string | null | If there is a number of elements where the location.hash value is used, it may be necessary to filter it to get the intended data. Pass in a string value, i.e.: 'collapse' and it'll load and filter through as needed while maintaining the remaining location hash values. this only gets used if 'useLocationHash' option is selected. |
| useLocationHash | boolean | true | Use the window.location.hash to open and close the items. |
| loadLocationHash | boolean | true | Loads with a location hash in the browser address bar, must of course be the ID of the item. |
| historyType | string | 'push' | If using using useLocationHash or a history of events, 'push' pushes a new state, and 'replace' replaces the current. |
| afterOpen | function | ($btnElems, $collapsibleItem) => { } | callback function after an item is opened. |
| afterClose | function | ($btnElems, $collapsibleItem) => { } | callback function after an item is closed. |
| afterInit | function | (element) => { } | callback function after collapse is initialized. |

This equalization script will work with any responsive classes your heart desires to use. It will take elements and measure their position top and add them to an array. Then it assigns the tallest height to that row, so they all are sized per row neatly. You can stop it at certain widths, you can start it, and there are other configurable options. If the equalize items are all in one column rows then no heights will be added. Look at the Settings for the rest.
| Option | Type | Default | Description |
|---|---|---|---|
| equalizeItem | string | '.equalize' | The class of the the item to be equalized |
| startWidth | number | 0 | The width to start the plugin's equalization process |
| stopWidth | number | 480 | The width in which it stops equalizing. Perhaps you have just one column, your not going to need to equalize anything! |
| timerDelay | number | 100 | The throttling delay on the resizing of the window/element. May need to be adjusted if other corresponding scripting is going on. |
| useHeight | boolean | false | Set to true will use 'height' instead use 'min-height' with css. |
| useMargin | boolean | false | Calculates in 'margin' and applies to the height |
| aligningCss | string | 'flex-l' | This is the class that lines up the containers for equalization. Other classes that do the same thing can be used. That or if you set up an inline-block class as well to line them up. |
| resizeCss | string | 'in-resize' | Transition effects will destroy equalization in certain scenarios, so this removes the transition while its being resized |
| fuzzy | number | 1 | The variance it can have so it doesn't need to be exactly aligned per pixel. So if an element is off by 1px it'll still align. |
The following is an example html structure for this plugin:
HTML
<div class="equalize-container">
<div class="sm-col-6 md-col-4 lg-col-3" >
<div class="equalize or-your-equalize-class box">
<h3>Demand Generation</h3>
<p> Hileman Group provides holistic demand generation services for our clients, from top-of-the-funnel tactics to nurturing tactics that drive the closing sale.</p>

<div class="sm-col-6 md-col-4 lg-col-3" >
<div class="equalize or-your-equalize-class box">

</div>
JavaScript
$('.equalize-container').equalizeContent();
By default it will load background images and images lazily once they appear in the viewport. But also run custom fuctions as well to hook into elements appearing (or disappearing) as well. This plugin uses window.IntersectionObserver. This plugin works to load images with the loading="lazy" attribute (yes it would work by itself!). It loads the image/iframe before the first pixel enters the viewport--see settings as we can pad so it can appear loaded once scrolled to. The loading="lazy" attribute only works once the first pixel enters the viewport, which may cause a blank space before the image loads.
| Option | Type | Default | Description |
|---|---|---|---|
| imgSrcName | string | 'src' | Name of the data attribute to load an image source. For example <img src="cleardot.gif" data-src="your-lazy-image.jpg">. |
| bgSrcName | string | 'bgSrc' | Name of the data attribute to load a background image. Use camel casing when changing. |
| loadImgs | boolean | true | Load images and background images. Built-in function for this since its the core intended functionality. |
| inEvt | Function | null | Custom function that hooks into the element appearing on screen. the lazyElem and entry are the two parameters passed, so inEvt(lazyElem, entry) = > {console.log(lazyElem, entry)}. |
| outEvt | Function | null | Custom function that hooks into the element disappearing in the viewport. Same parameters are passed as the inEvt function. |
| force | boolean | false | Pass in a custom condition that will just bypass the lazy load. |
| observerID | string | null | ID of window.IntersectionObserver which gets created with the 'new' operator, so one can get used for each instance. |
| unobserve | boolean | true | once entered in on the viewport, it'll unobserve. Make false should you want to re-observe an element. |
| observerOpts | object | { rootMargin: '48px' } | Object being passed is the 'options' argument for the IntersectionObserver, please refer to documentation regarding that here. |

<h1>Common Plugins and JavaScript for Websites</h1>
<p class="text-md">It's nearly inevitable your website will need these plugin's and functions for it to work. These are made to work with <a href="https://github.com/fabiospampinato/cash" target="_blank">Cash</a> (with jQuery still an option) as the only dependency.</p>
<h2>About</h2>
<p><a href="#page-bottom" class="smooth-scroll">Go To Page Bottom Smooth Scroll</a> Below are some common plugin's to help enhance your website. You'll notice some are missing (like a Carousel for example), that's because there are just some really, realy well made, IMO. Not touching that stuff, use it, its great. Others I always thought could be better, even though a few are frankly near duplicates 🤷🏻♂️. Anyways here we are, and you're stil reading this! If you download you probably work where I do, or somehow stumbled across.</p>
<h2>Some nice features are their is some shared syntax in the way they all operate.</h2>
<p><strong>For Example:</strong> all have options that can be plugged in as a data attribute, in JSON format (loosely written somehat)</p>
<code>
<div id="your-plugin-elem" data-plugin-name="{option:'text',option2: true, etc: 'you get the idea'}"></div>
</code>
<p><strong>For Example:</strong> all can have their configuration change. Which can come in handy sometimes when things get complex</p>
<code>
$('.your-plugin-elem').PluginOfSorts({change:'yep', height: 1e6})
</code>
JavaScript
//Background images... with a custom in event

}
});
| Option | Type | Default | Description |

| backDropClose | boolean | true | Toggle whether a user can click the backdrop to close the modal. |
| fromDOM | boolean | true | If the modal content is grabbed from the DOM. Set to false if grabbed via an AJAX call or otherwise generated. |
| modalCss | string | null | Additional modal css for styling or other scripting purposes |
| modalID | string | null | The ID of the modal. |
| src | string | null | CSS selector for DOM elements, or can be custom created element from data either from an AJAX call or computed otherwise. |
| useHashFilter | string | null | If there is a number of elements where the location.hash value is used, it may be necessary to filter it to get the intended data. Pass in a string value, i.e.: 'modal' and it'll load and filter through as needed while maintaining the remaining location hash values. this only gets used if 'useLocationHash' option is selected. |
| useLocationHash | boolean | true | Use the window.location.hash to open and close the items. |
| loadLocationHash | boolean | true | Loads with a location hash in the browser address bar, must of course be the ID of the item. |

| onOpen | object | (modalObj) => {} | Event that fires when the element is opened |
| afterClose | object | (modalObj) => {} | Event that fires after the element is closed |
This is an object with the following props/elements that is the first (and only) argument above in the callback functions (onOpenOnce,onOpen and afterClose). This should help allow for more flexibility with the prompt to attach any additional events or styling more easily. Below some examples with a little bit of custom code with this object.
{
$backdrop,
$content,
contentAppended: false, //state
$dialog, //modal dialog
$dialogContent, // modal dialog content
$closeBtn,
id: modalID,
$modal, //outermost element
disableModal: () => _.disableModal(), //disable modal fn
show: false //state

This plugin adds a delay to the desktop navigation and for the nestled <ul>'s that fly out. Also, features an edge detection on the drop-downs, and uses corresponding CSS to position, so it stays on the page. I think this is a nice feature to have and adds a small nice little touch to the finished project.

Plugin is strictly for mobile so other plugins can be used for the desktop nav if needed. The clicking action that allows for opening/closing nav item is handled via the visibility of the 'open/close' button so the click so no clashing between desktop and mobile happen. Also so CSS can control it tighter as sometimes device width may dictate whether or not you'll see the desktop or mobile view.

$('#main-nav').navMobile()
This plugin is for parallaxing page elements (and yes background images). Use the bgFill option and it'll magically expand to the height of its container if using a background image. It uses the translate3d property as its more efficient than using a top or left as well as requestAnimationFrame. Can be used to move elements either with a Y or X axis.
| Option | Type | Default | Description |
|---|---|---|---|
| speed | number | 7 | Speed of the scroll. A negative amount will move it in the opposite direction. |
| axis | string | 'y' | Axis of movement, it can be 'y','Y','x', or 'X' and is the axis in which the element moves. |
| relativeElem | boolean/HTMLElement/string | false | If you need to set the parallaxing of one element relative to the offset it's parent. Parent which needs to be specified, in a classname or HTML element. |
| $heightElem | HTMLElement | $(element) | the class or the element of the primary element to base the height off of. |
| initOffset | boolean | false | If parallaxing an element, it'll account for the position and adjust it back to its start as it would be positioned without the plugin. |
| bgFill | boolean | false | If it's a background image, this adds extra height to ensure it fills the area. |
| outStop | number | 1 | 1 = 100% of the height of the element. 0.5 = 50%, etc. If it's set to .5, the element will stop parallaxing if 50% of the element has left the viewport, instead of the 100% by default. |
| minWidth | number | null | The minimum width for the parallax effect to run. |
| maxWidth | number | null | The maximum width for the parallax effect to run. |
| scrollMaxPxStop | number | 5000 | max an item can scroll. Make this less should you want it to stop prior to exiting the screen. Good for when you have content that it shouldn't overlap. |
