怎样根据google chrome的请求信息判断请求是否成功？
我使用jquery的$.post方法提交数据，添加一条评论，php程序执行出错，可能自动终止了程序并返回了错误信息，$.post的回调函数也没有调用，但是在General部分的Status Code却是200，Response和Request部分也没有状态码，难道php程序出错也会返回一个200的状态码，怎样判断返回是否成功？

下面调试的地方有一个response题主可以看一下
<code>200只表示请求成功 </code>
在php中有一个设置是控制是否显示错误。
如果我没有记错的话，应该是display_error
如果这个开启，那么当程序错误的时候会显示对应的错误信息，因为要显示错误信息，所以一定是200。
之所以没有东西输出，是因为程序错误的时候你并没有输出东西到网页中去。
可能你将error_reporting设置为0了，也就是不输出错误。
PS：display_error是显示错误，error_reporting是输出哪一些错误
但是如果你将这个关闭后，如果一旦php错误，那么将会返回500。
