获取url参数并以对象输出

var str = "name=1&age=2&school=high";
   var a1 = str.split('&');
   var args = new Object();
   for (var i=0;i<a1.length;i++){
    var pos=a1[i].indexOf('=');
    if(pos==-1) continue;
    var argname=a1[i].substring(0,pos);
    var value=a1[i].substring(pos+1);
    args[argname]=unescape(value)
   }
   console.log(args)
// Object {name: "1", age: "2", school: "high"}
