前端获取后端定义Cookie的参数|前端获取URL?后参数的值

        //获取cookie中的参数
        function getCookiesPbyName(s) {
            var strcookie = document.cookie;
            strcookie = strcookie.replace(/\ +/g, "");
            strcookie = strcookie.replace(/[\r\n]/g, "");
            var arrcookie = strcookie.split(";");//分割
            for (var i = 0; i < arrcookie.length; i++) {
                var arr = arrcookie[i].split("=");
                if (arr[0] == s) {
                    return arr[1];
                }
            }
            return "";
        }

//获取url某个参数

        if (urlArr.length > 1) {
            var ParaArr = urlArr[1].split("&");
            //遍历匹配
            for (var i = 0; i < ParaArr.length; i++) {
