Jquery getScript caching

Question

By Default $.getScript() disables caching and you can use $.ajaxSetup and set caching to true. When testing if the script is actually cached with Firebug most of the time t

Answer 1

By default, $.getScript() sets the cache setting to false. This appends a timestamped query parameter to the request URL to ensure that the browser downloads the script each time it is requested.

jQuery doc site has a nice extension for not appending a timestamp to the request and bypass the cache:

jQuery.cachedScript = function( url, options ) {

  // Allow user to set any option except for dataType, cache, and url
  options = $.extend( options || {}, {
    dataType: "script",
    cache: true,
    url: url
  });


  // Use $.ajax() since it is more flexible than $.getScript
  // Return the jqXHR object so we can chain callbacks
  return jQuery.ajax( options );
};

// Usage
$.cachedScript( "ajax/test.js" ).done(function( script, textStatus ) {
  console.log( textStatus );
});
