JS request函数 用来获取url参数

function request(strParame) {
var args = new Object( );
var query = location.search.substring(1);

var pairs = query.split("&"); // Break at ampersand
for(var i = 0; i < pairs.length; i++) {
var pos = pairs[i].indexOf('=');
if (pos == -1) continue;
var argname = pairs[i].substring(0,pos);
var value = pairs[i].substring(pos+1);
value = decodeURIComponent(value);
args[argname] = value;
}
return args[strParame];
}
