[转]JS获取请求参数 --- http://hi.baidu.com/qiang860818/blog/item/a69bad6d32f2fbfd431694e2.html

<script language="javascript"> 
var url=window.location.search; 
if(url.indexOf("?")!=-1) 
{ 
var str = url.substr(1) 
strs = str.split("&"); 
for(i=0;i<strs.length;i++) 
{ 
document.write([strs[i].split("=")[0]],'＝',unescape(strs[i].split("=")[1]),'<br>'); 
} 
}else document.write('没有参数'); 
</script> 


你现在需要获取id的值，很简单，把我的程序代码改成如下： 

<script language="javascript"> 
var id=''; 
var url=window.location.search; 
if(url.indexOf("?")!=-1) 
{ 
var str = url.substr(1) 
strs = str.split("&"); 
for(i=0;i<strs.length;i++) 
{ 
if([strs[i].split("=")[0]]=='id') id=unescape(strs[i].split("=")[1]); 
} 
} 
</script>
