JS中location.search什么意思
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>

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;
}
