Jquery to get parameters in the URL to solve the problem of Chinese garbled code two ways

When passing parameters from page A to page B through url, the following two methods can be used to resolve url parameters:
Method 1: regular analysis

 
function getQueryString(name) { 
var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i"); 
var r = window.location.search.substr(1).match(reg); 
if (r != null) return unescape(r[2]); return null; 
} 

Call:

 
alert(GetQueryString(" Parameter names 1")); 
alert(GetQueryString(" Parameter names 2")); 
alert(GetQueryString(" Parameter names 3")); 

Method 2:

 
<span style="font-size: 16px;"><Script language="javascript"> 
function GetRequest() { 
var url = location.search; //Get the "?" in the url String after a string
var theRequest = new Object(); 
if (url.indexOf("?") != -1) { 
var str = url.substr(1); 
strs = str.split("&"); 
for(var i = 0; i < strs.length; i ++) { 
theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]); 
} 
} 
return theRequest; 
} 
</Script></span> 

Call:

 
<Script language="javascript"> 
var Request = new Object(); 
Request = GetRequest(); 
var  parameter 1, parameter 2, parameter 3, parameter N; 
 parameter 1 = Request[' parameter 1']; 
 parameter 2 = Request[' parameter 2']; 
 parameter 3 = Request[' parameter 3']; 
 parameter N = Request[' parameter N']; 
</Script> 

If the parameter contains Chinese characters, pay attention to transcoding and decoding:

 
<span style="font-size:18px;">1. The page refs  
Javascript Code: <script type= " text/javascript " > 
function send(){ 
var url = "test01.html"; 
var userName = $("#userName").html(); 
window.open(encodeURI(url + "?userName=" + userName)); } 
</script> 
2.  Receive parameters page: test02.html 
<script> 
var urlinfo = window.location.href;//Access to the url
var userName = urlinfo.split( " ? " )[1].split( " = " )[1];//Split the url to get the argument after "="
$( " #userName " ).html(decodeURI(userName)); 
</script></span>
