我正在从一个段落中找到一个特定的单词，并希望使其大胆。我已完成以下代码，但无法正常工作。
var text = /Lorem/ig;
$('div')
.filter(function() {
return text.test($(this).text())
}).wrap('<strong></strong>');<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has
survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing
software like Aldus PageMaker including versions of Lorem Ipsum.</div>$.fn.wrapInTag = function(opts) {
var tag = opts.tag || 'strong'
, words = opts.words || []
, regex = RegExp(words.join('|'), 'gi') // case insensitive
, replacement = '<'+ tag +'>Lorem</'+ tag +'>';
return this.html(function() {
return $(this).text().replace(regex, replacement);
});};
// Usage
$('div').wrapInTag({
tag: 'strong',
words: ['Lorem'] //can be comma seprated like ['Lorem','ipsum']
});
