Size Observer depends on jQuery. To use it, include this in your page :

Usage

To use this plugin you can directly specify a callback as first parameter. It will be call each time the size of the element changes.

You can also specify the properties to observes height or width as first parameter, and the callback as second parameter.

Example :

$(function() {
  $('img').onResize(function() {
    console.log('The size of this element changed: ', this);
  });

  // Same as:

  $('img').onResize(['height', 'width'], function() {
    console.log('The size of this element changed: ', this);
  });


  // Only check the height:

  $(document).onResize('height', function() {
    console.log('The height of the document changed: ', this);
  });


  // Only check the width:

  $(window).onResize('width', function() {
    console.log('The width of the window changed: ', this);
  });
});
