ajax返回值自动添加pre标签的解决方法

 //response = response.replace(/<pre>/ig, "").replace(/<\/pre>/ig, ""); //过滤
                if (response.indexOf("{") > -1 && response.indexOf("}") > -1) {
                    var beginx = response.indexOf("{");
                    var endx = response.lastIndexOf("}") + 1;
                    response = response.substring(beginx, endx);
                }
