编写一个参数JavaScript函数parseQueryString，它的用途是把url参数解析为一个对象

var url = "http://www.taobao.com/index.php?key0=0&key1=1&key2=2.............";

var obj = parseQueryString(url);

function parseQueryString(argu){

var str = argu.split('?')[1];

var result = {};

var temp = str.split('&');

for(var i=0; i<temp.length; i++)

{

var temp2 = temp[i].split('=');

result[temp2[0]] = temp2[1];

}

return result;

}
