调试一个ajax要吐血了 写了一个英汉词典,具体流程: 1. 把本地文件按照{English: Chinese}的格式写入memcached服务器 2. 通过ajax提交英语单词,并返回中文释义 遇到的问题: 查询对应的单词,可以通过file_put_contents函数写入本地,证明查询到了相应的单词,在客户端,通过readyState属性可以依次看到返回1,2,3,4,但是在window.alert(type res)时显示未定义。

ajax调试要吐血了
------解决思路---------------------- var
res =xmlhttp.responseXML;
window.alert(typeof
$res );
一样吗?不一样当然不行
------解决思路---------------------- sublime or notepad++
