Method 1: Regular Analysis 

copy code code show as below:

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; 
} 

Calling method: 
alert(GetQueryString("parameter name 1")); alert(GetQueryString("parameter name 2")); 
alert(GetQueryString("parameter name 3")); 

method 2 

copy code code show as below:

<script language="javascript"> 
function GetRequest() { 
var url = location.search; //获取url中"?"符后的字串 
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> 

Calling method: 
<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['parameter2']; 
parameter3 = Request['parameter3']; 
parameterN = Request['parameterN']; 
</script>
