问题描述

如果我的网址是 http://link-ads.blogspot.com/?url=http://could-be-any-url.com&name=123456789101112 使用 纯 javascript 我将如何提取 &client= 以便它提取 123456789101112 并将其设置为 var clientid = 123456789101112;

If my url is http://link-ads.blogspot.com/?url=http://could-be-any-url.com&name=123456789101112 using purely javascript how would I extract &client= so it would extract 123456789101112 and set it as var clientid = 123456789101112;

推荐答案

var clientid = (window.location.search.match(/[?&;]name=(\d+)/) || [])[1];

如果它可以包含多个数字，请使用类似...

If it can contain more than numbers, use something like...

var clientid = (window.location.search.match(/[?&;]name=([^&;]+)/) || [])[1];

如果找不到参数，则返回undefined.

If the param could not be found, it will return undefined.

如果您需要更频繁地执行此操作，最好使用 通用解决方案.

If you need to do this more often, you'd be better off with a generic solution.
