使用js Regex在URL中查找特定的静态文件

Question

How can I find if an URL has a file like this in its structure using regex?

http://domain.com/file.xxx
http://domain.com/.../file.xxx

Where file.xxx could be ( .css / .js / .jpg ) etc ?

Something like:

var staticURL = url.match(//) // verify if it matches

We suppose url is a function parameter.

Answer 1

You could do something like this:

var regex = /\.(css|js|jpg)$/i;
var staticURL = regex.test(url);

That will find a URL ending in .css, or .js, or .jpg, and it will ignore case sensitivity.
