问题描述
在某个元素中，我需要选择与某个正则表达式匹配的不同字符串，并用标签将它们包装起来.我该怎么办?
In a certain element, I need to select different strings that match a certain regex and wrap them with tags. How can I do that ?
我尝试过:
var str = jQuery("#my_div").html();
var regex = "\([a-z]{2}\)";
jQuery("#my_div").html(str.replace(regex, "<span>$1</span>"));
..但这将整个元素而不是元素中的所选字符串包装起来.
.. but this wraps the whole element instead of the selected string in the element.
推荐答案
示例的问题是您没有捕获组，请将正则表达式更改为(\([a-z]{2}\))
The problem with your example is you have no capturing group, change your regex to (\([a-z]{2}\))
以下是使用html进行正则表达式替换的示例: http://jsfiddle.net/gibble/NYVWg /
Here is an example of a working regex replace in html: http://jsfiddle.net/gibble/NYVWg/
<style>span.highlight { color: purple; }</style>
<body>bla bla <div id="test">this (is) some text this (is) some text</div> bla bla<body>
var oldHtml = $('#test').html();
var newHtml = oldHtml.replace(/(\([a-z]{2}\))/g,"<span class='highlight'>$1</span>");
$('#test').html(newHtml);
