Readme
Display DOM elements with fixed position (a popup) relative to an "owning" element. This is a neat workaround for stacking context limitations in CSS (z-index, overflow:hidden, et cetera)
This is a CommonJS module, you will need to use browserify.
Each Popup
instance is a simple <div>
element with fixed positioning (position:fixed
). This popup will be positioned relative to a specified owner
element. If the owner element changes position for whatever reason (window resize, scrolling, style changes by javascript, et cetera), so will the popup. The popup will also receive a max-width and max-height to prevent it from going outside the browser viewport.
Example:
var domv = require('domv');
var Popup = require('domv-popup');
var doc = domv.wrap(document);
var myButton = doc.selector('#myButton');
var myPopup;
var myPopupVisible = false;
// Toggle button to open/close the popup
myButton.on('click', function(e)
{
if (myPopupVisible)
{
// hide the popup
myPopupVisible = false;
// by removing it from the document
myPopup.removeNode();
}
else
{
// show the popup
myPopupVisible = true;
if (!myPopup)
{
// myButton is the owner of this Popup
myPopup = Popup.get(myButton);
myPopup.addClass('myPopup');
myPopup.textContent = 'This is a popup!';
// The top side of the popup is aligned the bottom side of the button
myPopup.alignTop = Popup.ALIGNMENT.BOTTOM;
// The left side of the popup is aligned the left side of the button
myPopup.alignLeft = Popup.ALIGNMENT.LEFT;
// The right side of the popup is aligned the right side of the button
myPopup.alignRight = Popup.ALIGNMENT.RIGHT;
}
// Add the popup back to the document after it has been previously removed
myPopup.addToAncestorOfOwner();
// Immediately update the position
myPopup.updatePositionNow();
// Automatically update the position as needed
// If the popup is removed from the document, the automatic updating stops
myPopup.autoUpdatePosition();
}
});
