JS中location.search什么意思？下面17javascript跟大家详细介绍一下：  
  
设置或获取 网页地址跟在问号后面的部分  
  
当以get方式在url中传递了请求参数时，可以利用location的search属性提取参数的值，下面的代码把参数的名称和对应的值存储在2个数组中。  
  
<script>  
function test()  
\{  
var url=window.location.search;  
if(url.indexOf("?")!=-1)  
\{  
   var str = url.substr(1)  
    strs = str.split("&");  
    var key=new Array(strs.length);  
    var value=new Array(strs.length);  
    for(i=0;i<strs.length;i++)  
    \{  
     key\[i\]=strs\[i\].split("=")\[0\]  
     value\[i\]=unescape(strs\[i\].split("=")\[1\]);  
    alert(key\[i\]+"="+value\[i\]);  
   \}  
\}  
\}  
< /script>

< html>  
< head><title>none</title>  
< script>  
function getParam(name)\{  
var params=location.search.substring(1).toLowerCase();alert('params='+params);  
var paramList=\[\];  
var param=null;  
var parami;  
if(params.length>0) \{  
if(params.indexOf("&") >=0) \{  
   paramList=params.split( "&" );  
\}else \{  
   paramList\[0\] = params;  
\}  
for(var i=0,listLength = paramList.length;i<listLength;i++) \{  
   parami = paramList\[i\].indexOf(name+"=" );  
   if(parami>=0) \{  
    param =paramList\[i\].substr(parami+(name+"=").length);  
   \}  
\}  
\}  
return param;  
\}
