Advanced tools
jPack is a vanilla javascript library of components, classes, plugin wrappers, and utilities designed to make building custom websites and web applications simpler.
But why?
Many plugins and libraries are too generic, verbose, bulky, lacking, or have a lot of dependencies. Much of what is included here is stuff that I've written several times, in several different ways, using jQuery in the past (or wrapping other jQuery plugins). The goal of this library is to allow me (and you, now that it's open source) to integrate slim, mostly dependency-free, components as-needed with more specific use-cases than what is currently offered elsewhere.
...where else can you get a component to grab a form from another page and stick it on the current one with XHR and XHR submission in 4 lines of custom JS?
| Component | Data Type | Singleton? | What it does |
|---|---|---|---|
| navigation | object | yes | Grabs HTML from a URL and replaces content on the current page. Handles browser history, meta title swaps, and offers several callbacks |
| XHRForm | class | no | Adds an on-submit listener and sends the form values using XHR with callbacks for success/failure |
| FormFromURL (extends XHRForm) | class | no | Grabs a form from a URL and places it on the current page (examples/FormModalFromURL shows how to put the form in a modal) and then uses an XHR request to submit the form |
| request | object | yes | Provides a wrapper for window.location and easy querystring interaction |
| Site | class | no | A generic website class with properties for id, name, and config - useful for multi-tenant applications where you need to know which site is being viewed |
| User | class | no | A generic user class with properties for id, name, email, phone, etc - also allows for front-end permission checks |
| strings | object | yes | Contains methods for semi-common string manipulation like creating a getter from a string ('hi' = 'getHi') |
| type_checks | object | yes | Validate the value of a variable with higher specificity than built-in functions. For instance, you can validate an object contains specific keys and throw errors if not, or if it contains keys that you didn't define |
| dom | object | yes | Has methods for converting just about anything into a native DOM Element or array of them (you can provide a string selector, jQuery object, native DOM object, etc). Also has some shortcuts for common DOM checks/manipulation (like removing an element, verifying an element exists in the DOM, or replacing an element with HTML) |
| events | object | yes | Includes methods for attaching event handlers including shorthand methods which create handlers that prevent the browser's default action (onclick, onsubmit) |
| ToggleOnMobile | class | no | Toggle an element's visibility when you click a button. By default, the element is visible, but if the button is visible, the element will be hidden until the button is clicked. If the element is visible and the user clicks outside of it, the element is hidden. If the window is resized, the element will be shown or hidden based on visibility of the button. |
Download the latest release, unzip and move it in your website's public folder, then include it in your HTML.
Use either jpack.min.js or jpack.bundled.min.js, BUT NOT BOTH. The bundled file includes the dependencies and you don't need them if you already have them in your project.
<script href="/@htmlguyllc/jpack/dist/jpack.bundled.min.js">

//wait for the page to finish loading so we know jpack is ready
window.addEventListener('load', function() {
//now you can take advantage of the jpack library
jpack.strings.ucfirst('bob'); //Bob
//if you want to change the namespace
jpack.setGlobal("$");
$.strings.ucfirst('bob');
//if you want to make all global without a namespace - do so at your own risk! Things may conflict!
jpack.setGlobal();
strings.ucfirst('bob');
};
</script>
npm i @htmlguyllc/jpack;
//or
yarn add @htmlguyllc/jpack;
//a single component from it's own file

|---|---|---|---|
| setPassthroughData | data:mixed | self | set data you want provided in the onload method for the next page |

| setIncomingElement | el:string | self | a selector string for the element being retrieved from another page which contains the HTML you want put on the current page |
| getIncomingElement | string | ||
| setReplaceElement | el:string | self | a selector string for the element on the current page you want the new HTML to replace |
| getReplaceElement | string | ||
| load | url:string, callback:function/null, incoming_el:string/null, replace_el:string/null, push_state:bool | void | pulls content from the provided URL and puts it on the current page - also swaps out the page title, metas, and much more |

| getLoaderDelay | self | ||
| getLoaderEl | Element | ||
| showLoader | self | shows the loader after the delay | |
| hideLoader | self | clears the loader timeout and hides it | |
| parseHTML | html:string, parent_el:string | object | parses HTML from the request to get key components like metas and the HTML to be displayed |
| getRouteFromMeta | html:string | string | retrieves the value of a meta tag named "current_route" to be passed in the onload event to help trigger page-specific JS |
| replacePageContent | html:string, url:string, incoming_el:string, replace_el:string, push_state:bool | self | replaces HTML on the page with the new content, updates metas, runs the unload and load callbacks and more |
| reload | callback:function | self | reloads the current page using .load() |

| triggerUnload | el:mixed, el_selector:string, route:string | self | triggers all unload callbacks |
| triggerNavigationFailure | error:string | self | triggers the nav failure and provides an error message |
| initHistoryHandlers | self | sets event listeners to handle back/forward navigation in the user's browser |
import {navigation} from '@htmlguyllc/jpack/es/navigation';
//handles browser back/forward buttons
navigation.initHistoryHandlers();
//a selector that contains the HTML you'd like to pull from the response
//the default is "body"
//if the response is a JSON object with an "html" key, it'll use the value of that
navigation.setIncomingElement('#main-content');
//a selector that will be replaced with the incoming HTML
//WARNING: If IncomingElement does not match, this will be overwritten by the IncomingElement after it's replaced
// (since it presumably no longer exists at that point)
//by default it'll replace anything in "body"
navigation.setReplaceElement('#main-content');
//enables a loader to show if a request takes more than 300ms
//WARNING: No styling is provided at this time
// It uses Bootstrap 4's progress-bar classes
navigation.loaderEnabled = true;
navigation.setLoaderDelay(300);
//things to do when a page loads
navigation.onLoad(function(e){
var params = e.detail; //get info from the event
//if a current_route meta was set in the incoming HTML, it'll be provided to you here
//you can use this to kick off your page-specific JS
var route = params.route;
//the data you set prior to loading the page, if any
var data = params.data; //or navigation.getPassthroughData()
//the DOM element that was added to the page replacing the previous
var el = params.el;
//el_selector is the IncomingElement selector that was used for this request
var el_selector = params.el_selector;
//replaced_selector is the ReplaceElement selector that was used for this request
//Note: If el_selector does not match replaced_selector, ReplaceElement will be replaced with IncomingElement
//It's done right after this callback and because it's assumed the ReplaceElement doesn't exist anymore
//If there's a situation where it does and you need it to stay the same, just set it again in here
//like this: navigation.setReplaceElement(params.replaced_selector);
var replaced_selector = params.replaced_selector;
//if gtag is set (google analytics), push a page view
if( typeof gtag !== 'undefined' ) {
gtag('config', 'GA_MEASUREMENT_ID', {
page_path: request.getURIWithQueryString()
});
}
//scroll to the top of the page
window.scrollTo(0, 0);
//.. do something...like init tooltip plugins
});
//things to do when leaving a page
navigation.onUnload(function(){
//.. do something...like remove generic event handlers or destroy plugins
});
//things to do when a page fails to load
navigation.onNavigationFailure(function(e){
var error = e.detail.error;
//.. do something...like show an error popup for the user or log the issue
});
//to prevent duplicate code, you can run your onload callbacks immediately
navigation.triggerOnLoad(dom.getElement('body'), 'body', navigation.getRouteFromMeta());
//now use the plugin to load pages
//if you're lazy, the fastest way to integrate is to just add data-href to all internal links
//and then attach a handler like this:
import {events} from '@htmlguyllc/jpack/es/events';
events.onClick('[data-href]', function(){
navigation.load(this.href);
});
//set something that will be received onload of the next page
navigation.setPassthroughData({
product_id:1
});
//you can use the load method at any time to load a new page
// the second param is an optional callback that only runs for that page
navigation.load('/my-page', function(new_el, new_el_selector, pass_through_params){
//my page is now loaded
//new_el is the new element on the page
//new_el_selector is the incomingSelector used for this request
//pass_through_data is any data that was set on navigation prior to this request
//so in this instance, it will be {product_id:1} (set above)
//now clear that data so it's gone for the next page load
navigation.clearPassthroughData();
});
//in some cases, you'll want to grab a different element from the URL
//this example grabs .popup-content from /my-popup and replaces .current-popup
navigation.load('/my-popup', function(new_el, el_sel, data){
//now the new element is on the page
}, '.popup-content', '.current-popup');

|---|---|---|---|
| constructor | form:Element,options:object | self | |
| setXHRSubmit | enabled:bool | self | enable/disable the XHR submission of the form |
| setSubmitMethod | method:string | self | override the form and provide a method (GET, POST, PATCH) |

| setSubmitURL | url:mixed | self | pass null to use the form's action, function to dynamically generate the URL (receives the form as a param), or string |
| getSubmitURL | url:string | returns whatever was set in the constructor or using setSubmitURL, not the final URL | |
| getFinalSubmitURL | form:Element | url:string | returns the URL the form will be submitted to after running the function (if it is one) and using all fallbacks |
| attachSubmitHandler | form:mixed | self | attaches the event listener to on submit of the passed form |

| setValidateCallback | callback:function | is_valid:bool | pass a function to validate the form and return true if it's valid, false if it's not. False prevents form submission so you must display errors for the user within here. The default callback uses Bootstrap 4's "was-validated" class to show errors and HTML5's :invalid attribute to validate |
| validate | form:Element | bool | passes the form to the validate callback and returns the response |

//shown with defaults
var remote_form = new XHRForm('form[name="my_form"]', {
xhrSubmit: true, //wouldn't make a whole lotta sent to use this if this were false lol, but it's here for extending classes and incase you want to toggle it for whatever reason
submitURL:null, //when null, the form's action will be used (if explicitly defined), otherwise it falls back to the URL the form was retrieved from
submitMethod:null, //when null, the form's method will be used (if explicitly defined), otherwise it falls back to POST

if( is_valid ) form.classList.remove('was-validated');
return is_valid;
}
});
//attach the submission handler
remote_form.attachSubmitHandler();
Grabs a form from a URL and places it on the current page (examples/FormModalFromURL shows how to put the form in a modal) and then uses an XHR request to submit the form

| clearOnloadCallbacks | self | removes all onload callbacks | |
| triggerOnload | form:Element | self | runs all onload callbacks and passes the form to them |
There are several methods and properties inherited from XHRForm that are not listed here. See XHRForm above for those details
import {FormFromURL} from '@htmlguyllc/jpack/es/forms';
//shown with defaults
var remote_form = new FormFromURL('/my-form', {
incomingElementSelector: null, //when null, it assumes the entire response is the form's HTML
insertIntoElement: null, //error on null, must provide this
onload: function(form){ return this; }, //although you can add more, you can only pass 1 to start with in the constructor
xhrSubmit: true,
submitURL:null, //when null, the form's action will be used (if explicitly defined), otherwise it falls back to the URL the form was retrieved from
submitMethod:null, //when null, the form's method will be used (if explicitly defined), otherwise it falls back to POST

if( is_valid ) form.classList.remove('was-validated');
return is_valid;
}
});
//grab the form and insert in into the "insertIntoElement"
remote_form.getForm();
Your javascript
import {FormFromURL} from '@htmlguyllc/jpack/es/forms';
new FormFromURL('/email-form', {
insertIntoElement: 'body.form-container',
}).getForm();
Your HTML
<div class="form-container"></div>
Server response when retrieving /email-form (or, just the HTML without the JSON wrapper)
{
"html": "<form><input name='email' required='required'><input type='submit' value='Submit'></form>"
}
Server response when submitting to /email-form (success)
{ "success": "Thank you for submitting, your email has been provided to spammers everywhere" }
Server response when submitting to /email-form (error)
{ "error": "Your email is required/Your email is invalid" }
FormFromURL extends XHRForm and either can be extended as you need.
See examples/FormModalFromURL for an example
| Method/Property | Params (name:type) | Return | Notes |

| query | n/a | URLSearchParams | see https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams#Methods |
| isHttps | bool | ||
| getDomain | string | ||
| getDomainWithProtocol | string | ||
| getURI | string | also known as the path - does not include querystring | |
| getURIWithQueryString | string | full URL after the domain | |
| getFullURL | string | ||
| appendSlash | string:string | string | adds a slash (if there isn't already one) to the end of a string. |
import {request} from '@htmlguyllc/jpack/es/request';
//get product_id from the querystring
var product_id = request.query.get('product_id');
var current_full_url = request.getFullURL();
var full_blog_url = request.appendSlash(request.getDomainWithProtocol())+'blog'; //https://my-domain.com/blog
| Method/Property | Params (name:type) | Return | Notes |
|---|---|---|---|
| getId | string/int | ||
| setId | id:string/int | this | |
| getName | string | this | |
| setName | name:string | this | |
| getConfig | object | this | |
| setConfig | config:object | this | overwrites all config |
| getConfigItem | mixed | returns an individual item from config | |
| setConfigItem | key:string,val:mixed | this | sets the value of an individual item in config |
| populate | data:object | this | sets provided values all at once (id,name,config) |
The easy way:
Create an object named $site with values from your server (prior to including jpack)
<script>
const $site = {
id: <?php echo $site['id']; ?>,
name: "<?php echo $site['name']; ?>",
//$site['config'] is a key/val array of configuration options
config: JSON.parse("<?php echo json_encode($site['config']); ?>"),
};
</script>
Then instantiate the Site class in your JS file somewhere
const cur_site = new Site($site);
cur_site.getId();
@see: /examples/CurrentSiteSingleton for a method of instantiating the current site once and using everywhere Note: Even though that creates a singleton which is available anywhere, it's still highly recommended that you pass that object to functions and methods where it is used (dependency injection)
The harder way:
Perform an XHR request to grab site details via a JSON API, then run the populate method on the site object.
import {Site} from '@htmlguyllc/jpack/es/site';
//this example uses jQuery's shorthand AJAX call, you can use axios or any request you want
$.get('/my-site-info-endpoint.php', function(data){
//don't forget error handling!
const cur_site = new Site(JSON.parse(data));
});
Of course you can use this class for any site, not just the current one, but this is the intended usage.

| setAdditionalData | data:object | this | |
| getDataItem | key:string | mixed | returns a single value from the additional data object/array |
| setDataItem | key:string, val:mixed | sets a single value in the additional data array/object | |
| populate | data:object | this | sets provided values all at once (id, isGuest, isAdmin, etc) |
The easy way:
Create an object named $user with values from your server
<script>
const $user = {
id: <?php echo $user['id']; ?>,
fname: "<?php echo $user['fname']; ?>",
//..
permissions: JSON.parse("<?php echo json_encode($user['permissions']); ?>"),
additionalData: JSON.parse("<?php echo json_encode([
'user_type'=>$user['user_type'],
//whatever else you might want to pass
]); ?>"),
//..
};
</script>
Then instantiate the User class in your JS file somewhere
const cur_user = new User($user);
cur_user.getId();
@see: /examples/CurrentUserSingleton for a method of instantiating the current user once and using everywhere Note: Even though that creates a singleton which is available anywhere, it's still highly recommended that you pass that object to functions and methods where it is used (dependency injection)
