Editor can edit a DataTable locally, without saving to a database, simply by excluding the ajax option from its configuration. When operating in this mode, Editor can still be used to edit the data,
including making use of its field type options and multi-row editing abilities, but the data is not submitted to the server, and thus not permanently stored.
In this example, data is loaded from the server, but no Ajax request is made when saving data (refreshing the page will cause the changes to be lost). This can be particularly useful if you want to save changes using a local mechanism rather than Editor's Ajax options (for example queuing all data before submitting with a custom button).
| Name | Position | Office | Extn. | Start date | Salary |
|---|---|---|---|---|---|
| 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 | var editor; // use a global for the submit and return data rendering in the examples$(document).ready(function() { editor = new $.fn.dataTable.Editor( { table: "#example", 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", type: "datetime" }, { label: "Salary:", name: "salary" } ] } ); $('#example').DataTable( { dom: "Bfrtip", ajax: "../../controllers/staff.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.
// No data yet submittedThe 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.
// No data yet received
