如何区分联合提交文件与使用后纽顿(上载)?
原标题:How to distinguish a JS-submit from using the back button (onbeforeunload)?

I am going crazy with the onbeforeunload and form.submit(). You are my last hope for a brilliant idea...

我采取的形式。 如果用户点击背纽顿,就会造成很多麻烦,因此窗户前卸载显示警告。 因此,在提交表格时,应允许使用。 提交文件为全球变量,以显示上载荷功能关闭。 至今为止,一切都是正确的。

有时必须通过联合材料自动提交表格。 而且,我无法利用称为表格的职能,提交(或更确切地说)用户将制定一些简单的法典,其中可包括表格。

问题是这种形式,具体来说,提交书并不引发提交书活动的形式。 因此,试图通过表格发送表格,提交文件经常告诉我考虑关闭该页。

因此,我回想: 是否有任何人对如何解决这一恶性循环有 br?

Thanks a lot BurninLeo

var form = document.getElementById( the-form ),

form.submit = function(){
    alert( caught submit );
    sub.apply(form);
