Installation

You can install blur-overlay from a package manager:

  • npm: npm install --save blur-overlay
  • bower: bower install --save blur-overlay

Or you can grab the latest .js file:

Usage

$(document).on('ready', function () {
 
  // Because Edge + CSS filters cause position bugs
  var browserIsEdge = /Edge\/\d+/.test(navigator.userAgent);
 
  // Grab the element you want to "wrap" with blur
  var $target = $('#something');
 
  // Grab the content you want to display in the overlay
  var $overlay = $('#overlay').detach().show();
 
  // Initialize the overlay
  $target.blurOverlay({
    // Overlay content
    content: $overlay,
    // Background color of the overlay (use rgba for opacity)
    backgroundColor: 'rgba(255, 255, 255, .25)',
    // Blur amount (default 12px)
    blurAmount: '10px',
    // Duration of CSS transitions
    transitionDuration: '500ms',
    // Type of CSS transitions
    transitionType: 'cubic-bezier(.22, .57, .27, .92)',
    // Elements to "mask" (adds an extra overlay to improve visual contrast)
    masks: [{
      selector: '.mask-me', // Required
      color: 'rgba(255, 255, 255, 0.5)',
      opacity: 1,
      width: '400px',
      height: '300px'
    }],
    // Override the z-index used for the overlay and masks
    zIndex: 3333,
    // Disable the blur filter (for incompatible/buggy browsers or whatever reason)
    noFilter: browserIsEdge
  });
 
  // Show the overlay
  $target.blurOverlay('show').then(function () {
    console.log('overlay is showing');
  });
 
  // Hide the overlay
  $target.blurOverlay('hide').then(function () {
    console.log('overlay is hidden');
  });
 
  // Update the content of the overlay
  $target.blurOverlay('content', '<p>New Content</p>');
 
  // Determine if the overlay is showing (true or false)
  console.log('Overlay is showing: ' + $target.blurOverlay('isShowing'));
 
  // Listen for events on the overlay
  $target.on('blurOverlay.beforeShow', function () {
    console.log('beforeShow event');
  });
  $target.on('blurOverlay.show', function () {
    console.log('show event');
  });
  $target.on('blurOverlay.beforeHide', function () {
    console.log('beforeHide event');
  });
  $target.on('blurOverlay.hide', function () {
    console.log('hide event');
  });
 
  // Destroy the plugin instance and clean up the DOM
  $target.blurOverlay('destroy');
 
});
