如何使用JQuery在HTML中查找文本? [英] How can I find text in HTML with JQuery?

问题描述

有没有一种方法可以搜索一些HTML，并且每当发现一个正则表达式时，都将其包装在一个span中?

Is there a way to perform a search some HTML and whenever it finds an occurrence of a regular expression, wrap it in a span?

例如:

<p>The rain in Spain stays mainly on the plain</p>

$('p').match('/ain/gi').each(function() {
  $(this).wrap('<span class="red"></span>');
});

推荐答案

我强烈建议以下更简单的方法:

I'd strongly suggest the following, simpler, approach:

// selects the 'p' elements, and calls the 'html()' method:
$('p').html(function (i,h) {
    // uses the anonymous function, i is the index of the current element
    // from the collection, h is the found HTML of that element.
    return h.replace(/(ain)/gi, '<span class="red">$1</span>');
});
