TypeError: $(...).unload is not a function - JQuery 3.1.0
提问by elG
I'm trying to execute a function before redirecting to other page, but when the original page loads I get the error that I wrote in the title:
我试图在重定向到其他页面之前执行一个函数,但是当原始页面加载时,我收到了我在标题中写的错误:
TypeError: $(...).unload is not a function
I've tried this:
我试过这个:
$( window ).unload(function() {
return "Bye now!";
});
And this:
和这个:
$(window).unload(function(){
cambiar_ruta();
alert(ruta);
});
But nothing is working,I don't even get a Leaving page warning.
但是没有任何效果,我什至没有收到离开页面警告。
With next code I don't get an error, but the function is never triggered and the alert never shown:
使用下一个代码,我没有收到错误消息,但从未触发该功能并且从未显示警报:
var ruta;
$(window).bind('onbeforeunload', function(e){
alert('Bye.');
cambiar_ruta();
alert(ruta);
});
I'm using jquery-3.1.0.min
我正在使用 jquery-3.1.0.min

Try to change like below, because you are using jquery-3
尝试如下更改,因为您使用的是 jquery-3
$(window).on("unload", function(e) {
alert("call");
console.log("this will be triggered");
});

正确答案是这样的:
$(window).on("beforeunload", function() {
// your codes
});

Unfortunately, as of Chrome on a PC in Apr 2020, this is not triggered
不幸的是,从 2020 年 4 月 PC 上的 Chrome 开始,这不会触发
