getUrlParam获取url参数

function getUrlParam(name) {
        var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");
        var r = window.location.search.substr(1).match(reg);
        if (r != null) return unescape(r[2]); return null;
    }

　　

正则表达式获取地址栏参数

var getParam = function (name) {
        var search = document.location.search;
        //alert(search);
        var pattern = new RegExp("[?&]" + name + "\=([^&]+)", "g");
        var matcher = pattern.exec(search);
        var items = null;
        if (null != matcher) {
            try {
                items = decodeURIComponent(decodeURIComponent(matcher[1]));
            } catch (e) {
                try {
                    items = decodeURIComponent(matcher[1]);
                } catch (e) {
                    items = matcher[1];
                }
            }
        }
        return items;
    };
