Using jQuery, how can I grab value from href?

I have a bunch of links on my page, in the format:

<a href="/q/10/Title">Title</a>

How can I grab the "10" from this link and use it as a variab开发者_StackOverflow社区le?

Thanks.

Use $('a').attr('href') to get the path, and then you can use String#split to break it up.

https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/String/split

You can search for 1 or more digits ([\d]+) with a regex in the href attribute of the a tag:

​var theNumber = /[\d]+/.exec( $("a").attr("href") );​​​​​​​​​​​​​

Try it out with this jsFiddle

The above will find the first number in the href of the first a tag. You can of course use other jQuery selectors.
