js获取url参数

getParam: function(url) {
            var data = decodeURI(url).split("?")[1];
            if (!data) {
                return {};
            }
            var param = {};
            var strs = data.split("&");

            for (var i = 0; i < strs.length; i++) {
                param[strs[i].split("=")[0]] = strs[i].split("=")[1];
            }
            return param;
        }
    }

• 应用示例

        /**
         * 获取上个页面传递过来的参数
         */
        var url = window.location.href;
        var params = functions.getParam(url);
