今天写项目需要获取url后面的参数ref参数来判断是否开启计时器来刷新页面，之前一直都是用JS写的,今天在查资料的时候看到了一款JQ的插件
项目地址：https://github.com/allmarkedup/purl
官网说明（英文不好，我翻译直译的）
Specifying the URL to parse
有几个不同的方式来选择什么网址解析：
/*---- 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
URL attributes
用attr()方法用于返回的URL不同部分的信息。例如：
var url = $.url('http://allmarkedup.com/folder/dir/index.html?item=value'); // jQuery version
var url = purl('http://allmarkedup.com/folder/dir/index.html?item=value'); // plain JS version
url.attr('protocol'); // returns 'http'
url.attr('path'); // returns '/folder/dir/index.html'
Query 参数化解析
/*---- 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'
我今天用到的是Query 参数化解析,上代码
