Plug-in Example
This example shows how to use a plugin for a custom column type. The DataTable.ext.searchBuilder.conditions
object allows for custom conditions
to be added to SearchBuilder. Details on the structure of the conditions to be added can be found at searchBuilder.conditions
.
Here the office column has been given a custom column type of office
using columns.type
. We are also adding some
conditions for this office
type to SearchBuilder which use select2. To use the custom filter from the plugin select Office > Equals and any
office, you will see that the last select
element is a select2 element.

The Javascript shown below is used to initialise the table shown in this example:
// Add custom conditions to the office column type
DataTable.ext.searchBuilder.conditions.office = {
'=': {
// This function decides whether to include the criteria in the search
isInputValid: function (el, that) {
// If no options have been selected, or one has but it has no value then do not include the criteria
if (
$(el[0]).has('option:selected').length < 1 ||
($(el[0]).has('option:selected').length === 1 &&
$($(el[0]).children('option:selected')[0]).text().length === 0)
) {
return false;
}
return true;
},
// This is the string displayed in the condition select
conditionName: 'Equals',
// This function gathers/sets the values from the dom elements created in the init function that are to be used for searching
inputValue: function (el) {
let values = [];
for (let element of el) {
if ($(element).is('select')) {
values.push(
$(element)
.children('option:selected')
.val()
);
}
}
// return the selected values
return values;
},
// This function initialises the criteria, specifically any dom elements that are required for its use
init: function (that, fn, preDefined = null) {
// As the select2 element is going to be populated with the values from the table,
// we need the row indexes and the column index.
let column = $(that.dom.data)
.children('option:selected')
.val();
let indexArray = that.s.dt
.rows()
.indexes()
.toArray();
let added = [];
// Declare select2 element
let el = $(
'<select class="js-example-placeholder-single js-states form-control" style="width: 300px"/>'
);
$(el).prepend('<option></option>');
// Set necessary listener to trigger search
el.on('select2:select', function () {
fn(that, el);
});
// for each row

let cell = that.s.dt.cell(index, column);
let value = {
filter: cell.render(
that.c.orthogonal.search

};
// If we have not already added this value
if (added.indexOf(value.filter) === -1) {
// Create the option to add to the select 2 element
let opt = $('<option>', {
text: value.text,
value: value.filter
})
.addClass(that.classes.option)
.addClass(that.classes.notItalic);
$(el).append(opt);
// Take note of the filter value so we do not add it again
added.push(value.filter);
// Check if it is preDefined and if so select it
if (preDefined !== null && opt.val() === preDefined[0]) {
opt.attr('selected', true);
}
}
}
// Trigger select2 on the select element when it is inserted into the dom
$(el).on('dtsb-inserted', function () {
if ($(el).hasClass('select2-hidden-accessible')) {
$(el).select2('destroy');
}
$(el).select2({ placeholder: 'Value' });
if (preDefined !== null) {
$(el).val(preDefined[0]);
$(el).trigger('input');
}
});
return el;
},
// Straightforward search function comparing value from table and comparison from the select2 element
// These values are retrieved in `inputValue`
search: function (value, comparison) {
return value === comparison[0];
}
}
};
$('#example').DataTable({
columnDefs: [{ type: 'office', targets: 2 }],
layout: {
top1: 'searchBuilder'
}
});

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.
