2 | * jQuery Highlight plugin | ||
3 | * | ||
4 | * Based on highlight v3 by Johann Burkard | ||
5 | * http://johannburkard.de/blog/programming/javascript/highlight-javascript-text-higlighting-jquery-plugin.html | ||
6 | * | ||
7 | * Code a little bit refactored and cleaned (in my humble opinion). | ||
8 | * Most important changes: | ||
9 | * - has an option to highlight only entire words (wordsOnly - false by default), | ||
10 | * - has an option to be case sensitive (caseSensitive - false by default) | ||
11 | * - highlight element tag and class names can be specified in options | ||
12 | * | ||
13 | * Usage: | ||
14 | * // wrap every occurrance of text 'lorem' in content | ||
15 | * // with <span class='highlight'> (default options) | ||
16 | * $('#content').highlight('lorem'); | ||
17 | * | ||
18 | * // search for and highlight more terms at once | ||
19 | * // so you can save some time on traversing DOM | ||
20 | * $('#content').highlight(['lorem', 'ipsum']); | ||
21 | * $('#content').highlight('lorem ipsum'); | ||
22 | * | ||
23 | * // search only for entire word 'lorem' | ||
24 | * $('#content').highlight('lorem', { wordsOnly: true }); | ||
25 | * | ||
26 | * // don't ignore case during search of term 'lorem' | ||
27 | * $('#content').highlight('lorem', { caseSensitive: true }); | ||
28 | * | ||
29 | * // wrap every occurrance of term 'ipsum' in content | ||
30 | * // with <em class='important'> | ||
31 | * $('#content').highlight('ipsum', { element: 'em', className: 'important' }); | ||
32 | * | ||
33 | * // remove default highlight | ||
34 | * $('#content').unhighlight(); | ||
35 | * | ||
36 | * // remove custom highlight | ||
37 | * $('#content').unhighlight({ element: 'em', className: 'important' }); | ||
