javascript 正则表达式从包含脚本标签的字符串中获取 url

Question

I am trying to figure out how to write a regex that would provide the url from a string like this:

'<script type="text/javascript" src="http://chrismills.la/test.js"></script>';

This works, but I need to find a cleaner way to do this:

var url = '';
_content.replace(/src ?= ?"([^"]+)"/gi, function(res) {
    url = res;
    url = url.replace('src=','');
    url = url.replace(/['"]+/g, '')
    url = url.replace(/["']+/g, '')
});
script.src = url;

SOLUTION, based on answer below:

var regex = /<script.*?src="(.*?)"/gmi;
var url = regex.exec(_content);
script.src = url[1];

Answer 1

You can use this regex:

<script.*?src="(.*?)"

Or also something like:

<script.*?"(http.*?)"

Updated the fiddle, let me know if this was what you are going for. Basically just creating a capture group:

            var srcRegEx = /src="(.*?)"/g;
            var source = srcRegEx.exec(_content);
            script.src = source[1];

Answer 3

If you want to match a string of script tags containing "http://chrismills.la" in the src attribute, you can use this Regex:

<script.*?src="(http:\/\/chrismills\.la.*?)"*<\/script>
