问题描述
如何从程序员端抑制所有JavaScript运行时错误弹出窗口?
How can I suppress all JavaScript runtime error popups, from the programmers side?
推荐答案
要抑制所有JavaScript错误,似乎成为 window.onerror
事件。
如果它被一个返回true的函数尽早替换(例如在头部之后) - 将不会出现错误弹出窗口,这在调试完成后非常有用。
To suppress all JavaScript errors there seems to be a window.onerror
event.
If it is replaced as early as possible(e.g. right after the head) by a function which returns true - there will be no error popups, which is quite useful after debugging is done.
<head>
<script type="text/javascript">
window.onerror = function(message, url, lineNumber) {
// code to execute on an error
return true; // prevents browser error messages
};
</script>
...
错误记录也是可能的,如这里
Error Logging is possible too, as explained here
