jquery 中获取URL参数的方法

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
