jquery获得url参数

发现很多人用jquery.query.js,但是这个有bug

下面这个比较好

https://github.com/allmarkedup/jQuery-URL-Parser

/*---- jQuery version -----*/
var url = $.url(); // parse the current page URL
var url = $.url('http://allmarkedup.com'); // pass in a URI as a string and parse that
var url = $('#myElement').url(); // extract the URL from the selected element and parse that - will work on any element with a `src`, `href` or `action` attribute.

/*---- plain JS version -----*/
var url = purl(); // parse the current page URL
var url = purl('http://allmarkedup.com'); // pass in a URI as a string and parse that 

/*---- jQuery version -----*/
$.url('http://allmarkedup.com?sky=blue&grass=green').param('sky'); // returns 'blue'

/*---- plain JS version -----*/
purl('http://allmarkedup.com?sky=blue&grass=green').param('sky'); // returns 'blue'
