javascript中不区分大小写的正则表达式 [英] Case insensitive regex in javascript

问题描述

您好我想使用JavaScript从我的URL中提取查询字符串，我想对查询字符串名称进行不区分大小写的比较。以下是我正在做的事情：

Hi I want to extract a query string from my URL using JavaScript, and I want to do a case insensitive comparison for the query string name. Here is what I am doing:

var results = new RegExp('[\\?&]' + name + '=([^&#]*)').exec(window.location.href);
        if (!results) { return 0; }
        return results[1] || 0;

但上面的代码执行区分大小写的搜索。我尝试了 /< regex> / i ，但它没有帮助。任何想法如何实现？

But the above code does a case sensitive search. I tried /<regex>/i but it did not help. any idea how can that be achieved?

推荐答案

你可以添加'i'修饰符，意思是忽略大小写

You can add 'i' modifier that means "ignore case"

var results = new RegExp('[\\?&]' + name + '=([^&#]*)', 'i').exec(window.location.href);
