JS取得URL所有参数

var name, value,strpar,strarr;
var str = location.href; //取得整地址栏?
var num = str.indexOf("?")
str = str.substr(num + 1); //取得所有参数
var arr = str.split("&"); //各个参数放到数组里
for (var i = 0; i < arr.length; i++) {
num = arr[i].indexOf("=");
if (num > 0) {
name = arr[i].substring(0, num);
value = arr[i].substr(num + 1);
this[name] = value;
strpar = strpar + this[name] + ",";
}
}
 
this[name]就是参数
 

 
strarr = strpar.split(",");
window.location = "/Search.aspx?type=search&sel=" + strarr[1] + "&key=" + strarr[2]"
