This option defines how that Ajax call is made and where to.\n *\n * The `ajax` property has three different modes of operation, depending on\n * how it is defined. These are:\n *\n * * `string` - Set the URL from where the data should be loaded from.\n * * `object` - Define properties for `jQuery.ajax`.\n * * `function` - Custom data get function\n *\n * `string`\n * --------\n *\n * As a string, the `ajax` property simply defines the URL from which\n * DataTables will load data.\n *\n * `object`\n * --------\n *\n * As an object, the parameters in the object are passed to\n * [jQuery.ajax](http://api.jquery.com/jQuery.ajax/) allowing fine control\n * of the Ajax request. DataTables has a number of default parameters which\n * you can override using this option. Please refer to the jQuery\n * documentation for a full description of the options available, although\n * the following parameters provide additional options in DataTables or\n * require special consideration:\n *\n * * `data` - As with jQuery, `data` can be provided as an object, but it\n * can also be used as a function to manipulate the data DataTables sends\n * to the server. The function takes a single parameter, an object of\n * parameters with the values that DataTables has readied for sending. An\n * object may be returned which will be merged into the DataTables\n * defaults, or you can add the items to the object that was passed in and\n * not return anything from the function. This supersedes `fnServerParams`\n * from DataTables 1.9-.\n *\n * * `dataSrc` - By default DataTables will look for the property `data` (or\n * `aaData` for compatibility with DataTables 1.9-) when obtaining data\n * from an Ajax source or for server-side processing - this parameter\n * allows that property to be changed. You can use Javascript dotted\n * object notation to get a data source for multiple levels of nesting, or\n * it my be used as a function. As a function it takes a single parameter,\n * the JSON returned from the server, which can be manipulated as\n * required, with the returned value being that used by DataTables as the\n * data source for the table. This supersedes `sAjaxDataProp` from\n * DataTables 1.9-.\n *\n * * `success` - Should not be overridden it is used internally in\n * DataTables. To manipulate / transform the data returned by the server\n * use `ajax.dataSrc`, or use `ajax` as a function (see below).\n *\n * `function`\n * ----------\n *\n * As a function, making the Ajax call is left up to yourself allowing\n * complete control of the Ajax request. Indeed, if desired, a method other\n * than Ajax could be used to obtain the required data, such as Web storage\n * or an AIR database.\n *\n * The function is given four parameters and no return is required. The\n * parameters are:\n *\n * 1. _object_ - Data to send to the server\n * 2. _function_ - Callback function that must be executed when the required\n * data has been obtained. That data should be passed into the callback\n * as the only parameter\n * 3. _object_ - DataTables settings object for the table\n *\n * Note that this supersedes `fnServerData` from DataTables 1.9-.\n *\n * @type string|object|function\n * @default null\n *\n * @dtopt Option\n * @name DataTable.defaults.ajax\n * @since 1.10.0\n *\n * @example\n * // Get JSON data from a file via Ajax.\n * // Note DataTables expects data in the form `{ data: [ ...data... ] }` by default).\n * $('#example').dataTable( {\n * \"ajax\": \"data.json\"\n * } );\n *\n * @example\n * // Get JSON data from a file via Ajax, using `dataSrc` to change\n * // `data` to `tableData` (i.e. `{ tableData: [ ...data... ] }`)\n * $('#example').dataTable( {\n * \"ajax\": {\n * \"url\": \"data.json\",\n * \"dataSrc\": \"tableData\"\n * }\n * } );\n *\n * @example\n * // Get JSON data from a file via Ajax, using `dataSrc` to read data\n * // from a plain array rather than an array in an object\n * $('#example').dataTable( {\n * \"ajax\": {\n * \"url\": \"data.json\",\n * \"dataSrc\": \"\"\n * }\n * } );\n *\n * @example\n * // Manipulate the data returned from the server - add a link to data\n * // (note this can, should, be done using `render` for the column - this\n * // is just a simple example of how the data can be manipulated).\n * $('#example').dataTable( {\n * \"ajax\": {\n * \"url\": \"data.json\",\n * \"dataSrc\": function ( json ) {\n * for ( var i=0, ien=json.length ; i
