* jQuery Highlight plugin * * Based on highlight v3 by Johann Burkard * http://johannburkard.de/blog/programming/javascript/highlight-javascript-text-higlighting-jquery-plugin.html * * Code a little bit refactored and cleaned (in my humble opinion). * Most important changes: * - has an option to highlight only entire words (wordsOnly - false by default), * - has an option to be case sensitive (caseSensitive - false by default) * - highlight element tag and class names can be specified in options * * Usage: * // wrap every occurrance of text 'lorem' in content * // with (default options) * $('#content').highlight('lorem'); * * // search for and highlight more terms at once * // so you can save some time on traversing DOM * $('#content').highlight(['lorem', 'ipsum']); * $('#content').highlight('lorem ipsum'); * * // search only for entire word 'lorem' * $('#content').highlight('lorem', { wordsOnly: true }); * * // don't ignore case during search of term 'lorem' * $('#content').highlight('lorem', { caseSensitive: true }); * * // wrap every occurrance of term 'ipsum' in content * // with * $('#content').highlight('ipsum', { element: 'em', className: 'important' }); * * // remove default highlight * $('#content').unhighlight(); * * // remove custom highlight * $('#content').unhighlight({ element: 'em', className: 'important' }); * * * Copyright (c) 2009 Bartek Szopka * * Licensed under MIT license. * */
