DataTables has a number of default parameters which * you can override using this option. Please refer to the jQuery * documentation for a full description of the options available, although * the following parameters provide additional options in DataTables or * require special consideration: * * * `data` - As with jQuery, `data` can be provided as an object, but it * can also be used as a function to manipulate the data DataTables sends * to the server. The function takes a single parameter, an object of * parameters with the values that DataTables has readied for sending. An * object may be returned which will be merged into the DataTables * defaults, or you can add the items to the object that was passed in and * not return anything from the function. This supersedes `fnServerParams` * from DataTables 1.9-. * * * `dataSrc` - By default DataTables will look for the property `data` (or * `aaData` for compatibility with DataTables 1.9-) when obtaining data * from an Ajax source or for server-side processing - this parameter * allows that property to be changed. You can use Javascript dotted * object notation to get a data source for multiple levels of nesting, or * it my be used as a function. As a function it takes a single parameter, * the JSON returned from the server, which can be manipulated as * required, with the returned value being that used by DataTables as the * data source for the table. This supersedes `sAjaxDataProp` from * DataTables 1.9-. * * * `success` - Should not be overridden it is used internally in * DataTables. To manipulate / transform the data returned by the server * use `ajax.dataSrc`, or use `ajax` as a function (see below). * * `function` * ---------- * * As a function, making the Ajax call is left up to yourself allowing * complete control of the Ajax request.

This is the * default that DataTables uses (incrementally increased for each column). * * `string` - read an object property from the data source. There are * three 'special' options that can be used in the string to alter how * DataTables reads the data from the source object: * * `.` - Dotted Javascript notation. Just as you use a `.` in * Javascript to read from nested objects, so to can the options * specified in `data`. For example: `browser.version` or * `browser.name`. If your object parameter name contains a period, use * `\\` to escape it - i.e. `first\\.name`. * * `[]` - Array notation. DataTables can automatically combine data * from and array source, joining the data with the characters provided * between the two brackets. For example: `name[, ]` would provide a * comma-space separated list from the source array. If no characters * are provided between the brackets, the original array source is * returned. * * `()` - Function notation. Adding `()` to the end of a parameter will * execute a function of the name given. For example: `browser()` for a * simple function on the data source, `browser.version()` for a * function in a nested property or even `browser().version` to get an * object property if the function called returns an object. Note that * function notation is recommended for use in `render` rather than * `data` as it is much simpler to use as a renderer. * * `null` - use the original data source for the row rather than plucking * data directly from it. This action has effects on two other * initialisation options: * * `defaultContent` - When null is given as the `data` option and * `defaultContent` is specified for the column, the value defined by * `defaultContent` will be used for the cell. * * `render` - When null is used for the `data` option and the `render` * option is specified for the column, the whole data source for the * row is used for the renderer. * * `function` - the function given will be executed whenever DataTables * needs to set or get the data for a cell in the column. The function * takes three parameters: * * Parameters: * * `{array|object}` The data source for the row * * `{string}` The type call data requested - this will be 'set' when * setting data or 'filter', 'display', 'type', 'sort' or undefined * when gathering data. Note that when `undefined` is given for the * type DataTables expects to get the raw data for the object back< * * `{*}` Data to set when the second parameter is 'set'. * * Return: * * The return value from the function is not required when 'set' is * the type of call, but otherwise the return is what will be used * for the data requested. * * Note that `data` is a getter and setter option. If you just require * formatting of data for output, you will likely want to use `render` which * is simply a getter and thus simpler to use. * * Note that prior to DataTables 1.9.2 `data` was called `mDataProp`. The * name change reflects the flexibility of this property and is consistent * with the naming of mRender.

Like `data` * this option can be given in a number of different ways to effect its * behaviour: * * * `integer` - treated as an array index for the data source. This is the * default that DataTables uses (incrementally increased for each column). * * `string` - read an object property from the data source. There are * three 'special' options that can be used in the string to alter how * DataTables reads the data from the source object: * * `.` - Dotted Javascript notation. Just as you use a `.` in * Javascript to read from nested objects, so to can the options * specified in `data`. For example: `browser.version` or * `browser.name`. If your object parameter name contains a period, use * `\\` to escape it - i.e. `first\\.name`. * * `[]` - Array notation. DataTables can automatically combine data * from and array source, joining the data with the characters provided * between the two brackets. For example: `name[, ]` would provide a * comma-space separated list from the source array. If no characters * are provided between the brackets, the original array source is * returned. * * `()` - Function notation. Adding `()` to the end of a parameter will * execute a function of the name given. For example: `browser()` for a * simple function on the data source, `browser.version()` for a * function in a nested property or even `browser().version` to get an * object property if the function called returns an object. * * `object` - use different data for the different data types requested by * DataTables ('filter', 'display', 'type' or 'sort'). The property names * of the object is the data type the property refers to and the value can * defined using an integer, string or function using the same rules as * `render` normally does. Note that an `_` option _must_ be specified. * This is the default value to use if you haven't specified a value for * the data type requested by DataTables. * * `function` - the function given will be executed whenever DataTables * needs to set or get the data for a cell in the column. The function * takes three parameters: * * Parameters: * * {array|object} The data source for the row (based on `data`) * * {string} The type call data requested - this will be 'filter', * 'display', 'type' or 'sort'. * * {array|object} The full data source for the row (not based on * `data`) * * Return: * * The return value from the function is what will be used for the * data requested. * * @type string|int|function|object|null * @default null Use the data source value. * * @name DataTable.defaults.column.render * @dtopt Columns * * @example * // Create a comma separated list from an array of objects * $(document).ready( function() { * $('#example').dataTable( { * "ajaxSource": "sources/deep.txt", * "columns": [ * { "data": "engine" }, * { "data": "browser" }, * { * "data": "platform", * "render": "[, ].name" * } * ] * } ); * } ); * * @example * // Execute a function to obtain data * $(document).ready( function() { * $('#example').dataTable( { * "columnDefs": [ { * "targets": [ 0 ], * "data": null, // Use the full data source object for the renderer's source * "render": "browserName()" * } ] * } ); * } ); * * @example * // As an object, extracting different data for the different types * // This would be used with a data source such as: * // { "phone": 5552368, "phone_filter": "5552368 555-2368", "phone_display": "555-2368" } * // Here the `phone` integer is used for sorting and type detection, while `phone_filter` * // (which has both forms) is used for filtering for if a user inputs either format, while * // the formatted phone number is the one that is shown in the table. * $(document).ready( function() { * $('#example').dataTable( { * "columnDefs": [ { * "targets": [ 0 ], * "data": null, // Use the full data source object for the renderer's source * "render": { * "_": "phone", * "filter": "phone_filter", * "display": "phone_display" * } * } ] * } ); * } ); * * @example * // Use as a function to create a link from the data source * $(document).ready( function() { * $('#example').dataTable( { * "columnDefs": [ { * "targets": [ 0 ], * "data": "download_link", * "render": function ( data, type, full ) { * return '<a href="'+data+'">Download</a>'; * } * } ] * } ); * } ); */ "mRender": null, /** * Change the cell type created for the column - either TD cells or TH cells.
