我无法在Chrome中触发卸载事件 [英] I can't trigger the unload event in Chrome
问题描述
这段代码在Firefox上运行良好，但我无法让Chrome上的卸载事件工作。 Chrome是否停止支持卸载活动了？
This code runs fine on Firefox, but I can't make the unload event work on Chrome anymore. Did Chrome stop supporting the unload event?

<script type="text/javascript">
function pageHidden(evt) { alert("Are you sure 1?"); } //WORKS ON FIREFOX BUT NOT IN CHROME
window.addEventListener("pagehide", pageHidden, false);
window.onunload = function () { alert("Are you sure 2?"); } //TRIGGERS ON LOAD NOT ON UNLOAD
$(window).unload(function () { //WORKS ON FIREFOX BUT NOT IN CHROME
alert("Are you sure 3?");
});

如何让unload事件在Chrome中运行？
How can I get the unload event to work in Chrome?
谢谢！
答案：
不测试卸载事件警报;）
推荐答案
window.onunload = alert("Are you sure 2?");
这是不正确的。您将 onunload 设置为 alert 的结果，您需要将其设置为函数：
This is incorrect. You are setting onunload to the result of alert, you need to set it to a function:
window.onunload = function(){
alert("Are you sure?");
}
如果你想使用jQuery，这将适用于所有浏览器。
If you want to use jQuery, this will work in all browsers.
$(window).unload(function () {
alert("Are you sure?");
});
注意：它可能似乎就像它的不在Chrome中工作，但确实如此。那是因为Chrome会在 onunload 事件中阻止 alert 。
NOTE: It might seem like it's not working in Chrome, but it is. That's because Chrome blocks alerts in the onunload event.
