By default Editor will use the tr element's id attribute to identify the row to the server (more specifically this will typically
contain the database's primary key to uniquely identity the row). While this default method can be very useful, particularly if you use the DT_RowId
JSON option to set the id, you may wish to read the row's id from the JSON data source, rather than the DOM. This is easily done using the idSrc option.
The example below, with idSrc is
set to id is suitable for cases where the data source objects look like: { "id": 2, "first_name": "Fiona", ...}. Like other data source
options the idSrc option can be given
in dotted object notation to read nested objects.
| Name | Position | Office | Extn. | Start date | Salary |

The Javascript shown below is used to initialise the table shown in this example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 | var editor; // use a global for the submit and return data rendering in the examples$(document).ready(function() { editor = new $.fn.dataTable.Editor( { "ajax": "../php/jsonId.php", "table": "#example", "idSrc": "id", "fields": [ { "label": "First name:", "name": "first_name" }, { "label": "Last name:", "name": "last_name" }, { "label": "Position:", "name": "position" }, { "label": "Office:", "name": "office" }, { "label": "Extension:", "name": "extn" }, { "label": "Start date:", "name": "start_date" }, { "label": "Salary:", "name": "salary" } ] } ); $('#example').DataTable( { dom: "Bfrtip", ajax: "../php/jsonId.php", columns: [ { data: null, render: function ( data, type, row ) { // Combine the first and last names into a single table field return data.first_name+' '+data.last_name; } }, { data: "position" }, { data: "office" }, { data: "extn" }, { data: "start_date" }, { data: "salary", render: $.fn.dataTable.render.number( ',', '.', 0, '$' ) } ], select: true, buttons: [ { extend: "create", editor: editor }, { extend: "edit", editor: editor }, { extend: "remove", editor: editor } ] } );} ); |
In addition to the above code, the following Javascript library files are loaded for use in this example:
Editor submits and retrieves information by Ajax requests. The two blocks below show the data that Editor submits and receives, to and from the server. This is updated live as you interact with Editor so you can see what is submitted.
The following shows the data that has been submitted to the server when a request is made to add, edit or delete data from the table.
1 | // No data yet submitted |
The following shows the data that has been returned by the server in response to the data submitted on the left and is then acted upon.
1 | // No data yet received |
