You should handle the onbeforeunload event... 您应该处理onbeforeunload事件...
function closeEditorWarning(){
return 'Are you sure?'
}
window.onbeforeunload = closeEditorWarning;
Or use jquery, window.attachEvent / window.addEventListener to do it nicely 或者使用jquery，window.attachEvent / window.addEventListener很好地做到这一点

onunload is not very useful (in my opinion) as you can't do anything with the confirm ation you're requesting (except maybe attempt to new another window with window.open , so onbeforeunload is more useful for this case. onunload并不是很有用（在我看来），因为您无法对所请求的confirm 做任何事情（除了可能尝试使用window.open新建另一个窗口，因此onbeforeunload在这种情况下更有用。
Your better bet is onbeforeunload , which is great but won't work in Opera (though this usually isn't a deal breaker). 更好的选择是onbeforeunload ，这很好，但在Opera中不起作用（尽管这通常不会破坏交易）。
Like ivy said, it would look something like this: 就像常春藤说的那样，它看起来像这样：
<script>
var userIsEditingSomething; // set this if something crazy happens
oldOnBeforeUnload = window.onbeforeunload;
window.onbeforeunload = function () {
// attempt to handle a previous onbeforeunload
if ('function' === typeof oldOnBeforeUnload) {
var message = oldOnBeforeUnload();
if ('undefined' !== typeof message) {
if (confirm('string' === typeof message ? message : 'Are you sure you want to leave this page?')) {
return; // allow user to exit without further annoying pop-ups
}
}
}
// handle our own
if (userIsEditingSomething) {
return 'Are you sure you want to exit?';
}
};
</script>

function doUnload()
{
// use confirm dialog box here
confirm("Window is closing...");
}
<body onunload="doUnload()">
