By default, when using inline editing, Editor will submit only the value of the field that has been edited (with no Ajax submission happening if the value has
not changed). This behaviour is controlled by the form-options object that is passed into the inline() method, or the formOptions.inline initialisation option and has three modes of operation:
changed - Submit only the changed field (the default for inline editing), and only if the value has changedallIfChanged - Submit the values of all fields if one or more have changed. If none have changed, nothing will
be submittedall - Submit all field values, even if there are no changes.This example demonstrates the allIfChanged option, which can be useful if you need to perform calculations on the
server-side based on information in the row, regardless of which field value was altered. The effect of this parameter can be observed in the Submitted
data section of the Ajax data tab below the table where you will see the full data for a row after editing a field.

The Javascript shown below is used to initialise the table shown in this example:
var editor; // use a global for the submit and return data rendering in the examples
$(document).ready(function() {
editor = new $.fn.dataTable.Editor( {
ajax: "/api/staff",
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').on( 'click', 'tbody td:not(:first-child)', function (e) {
editor.inline( this, {
submit: 'allIfChanged'
} );
} );
$('#example').DataTable( {
dom: "Bfrtip",
ajax: "/api/staff",
columns: [
{
data: null,
defaultContent: '',
className: 'select-checkbox',
orderable: false
},
{ data: "first_name" },
{ data: "last_name" },
{ data: "position" },
{ data: "office" },
{ data: "start_date" },
{ data: "salary", render: $.fn.dataTable.render.number( ',', '.', 0, '$' ) }
],
order: [ 1, 'asc' ],
select: {
style: 'os',
selector: 'td:first-child'
},
buttons: [
{ extend: "create", editor: editor },
{ extend: "edit", editor: editor },
{ extend: "remove", editor: editor }
]
} );
} );

The HTML shown below is the raw HTML table element, before it has been enhanced by DataTables:
This example uses a little bit of additional CSS beyond what is loaded from the library files (below), in order to correctly display the table. The additional CSS used is shown below:
The following CSS library files are loaded for use in this example to provide the styling of the table:
This table loads data by Ajax. The latest data that has been loaded is shown below. This data will update automatically as any additional data is loaded.
The script used to perform the server-side processing for this table is shown below. Please note that this is just an example script using PHP. Server-side processing scripts can be written in any language, using the protocol described in the DataTables documentation.
