* This feature plug-in for DataTables will highlight search terms in the
|
|
|
17 |
* DataTable as they are entered into the main search input element, or via the
|
|
|
18 |
* `search()` API method.
|
|
|
19 |
*
|
|
|
20 |
* It depends upon the jQuery Highlight plug-in by Bartek Szopka:
|
|
|
21 |
* http://bartaz.github.io/sandbox.js/jquery.highlight.js
|
|
|
22 |
*
|
|
|
23 |
* Search highlighting in DataTables can be enabled by:
|
|
|
24 |
*
|
|
|
25 |
* * Adding the class `searchHighlight` to the HTML table
|
|
|
26 |
* * Setting the `searchHighlight` parameter in the DataTables initialisation to
|
|
|
27 |
* be true
|
|
|
28 |
* * Setting the `searchHighlight` parameter to be true in the DataTables
|
|
|
29 |
* defaults (thus causing all tables to have this feature) - i.e.
|
|
|
30 |
* `$.fn.dataTable.defaults.searchHighlight = true`.
|
|
|
