自动反馈JavaScript错误 [英] Automatic feedback on JavaScript error

问题描述

如果在客户端运行JavaScript时发生错误（甚至语法错误），是否有自动反馈的方法？

Is there a way to get an automatic feedback if an error (even syntax errors) occurs when running a JavaScript on the client side?

我在想像这样：

<script src="debugger.js"></script>
<script>
    // some script with an error in it
</script>

每次调试器注意到错误，它会向服务器发送反馈。

And every time the debugger notices an error it sends a feedback to the server.

推荐答案

编辑：我最初误解了你的问题，这应该是有效的：

I misunderstood your question initially, this should work:

这需要在任何可能导致错误的JavaScript之前去。

Also note, this needs to go BEFORE any javascript that might cause errors.

window.onerror = function(msg,u,l)
{
    txt ="Error: " + msg + "\n";
    txt+="URL: " + u + "\n";
    txt+="Line: " + l + "\n\n";
    //Insert AJAX call that passes data (txt) to server-side script
    return true;
};

对于语法错误，你没有运气。当有语法错误时，Javascript就会死机。没有办法处理它。

As for syntax errors, you're out of luck. Javascript simply dies when there's a syntax error. There's no way to handle it at all.
