js 获取url的request参数

function getRequest(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];
}

//获取url参数--摘自 we7CMS/Script/Common.js
var Request = {
parameter: function(name) {
return this.parameters()[name];
},

parameters: function() {
var result = {};
var url = window.location.href;
var parameters = url.slice(url.indexOf('?') + 1).split('&');

for (var i = 0; i < parameters.length; i++) {
//var parameter = parameters[i].split('=');
var index = parameters[i].indexOf("=");
var name = parameters[i].slice(0, index);
var value = parameters[i].slice(index + 1, parameters[i].length + 1);
result[name]= value;
}
return result;
}
}
调用方法：
var folder = Request.parameter("folder");

function getQueryParam(name) {
var regex = RegExp('[?&]' + name + '=([^&]*)');

var match = regex.exec(location.search) || regex.exec(path);
return match && decodeURIComponent(match[1]);
}
