js 获取url的request参数

 方法1：

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];
    }

调用方法：var id=getRequest("id");

 方法2

//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");

 方法3 摘自extjs-4.1.1/examples/shared/include-theme.js

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

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

调用方法：

 var id = getQueryParam("name");
