清除Onbeforeunload [英] Clear Onbeforeunload

问题描述

我有一个用 ajax 提交的文本区域，该文本区域使用onbeforeunload来警告用户，如果他们尝试关闭浏览器，则他们尚未提交该文本区域.问题是我需要以某种方式清除 ajax 提交成功后的onbeforeunload，以便onbeforeunload知道用户已成功提交了表单.有没有一种方法可以使用一行代码来清除onbeforeunload，类似于clearTimeout或clearInterval?我将显示我当前拥有的onbeforeunload代码，尽管我认为这并不重要，但我正在寻找其他函数来清除此问题.请没有框架.谢谢.

I have a textarea that is submitted with ajax that uses onbeforeunload to warn the user that they have not submit the textarea if they try to close the browser. The problem is I need to somehow clear the onbeforeunload within the success of the ajax submit so that onbeforeunload knows that the user has submitted the form successfully. Is there a way to clear the onbeforeunload with a line of code, similar to a clearTimeout or clearInterval? I'll show the onbeforeunload code I currently have even though I don't think it matters much b/c I'm looking for a different function to clear this. No frameworks please. Thank you.

函数调用

unsavedChangesWarning();

Onbeforeunload函数

Onbeforeunload Function

function unsavedChangesWarning(){
    window.onbeforeunload = function(){
        return 'If you close this page you will lose your stride update!';
    };
}

推荐答案

window.onbeforeunload = null 将清除它.在尝试将用户重定向到任何地方之前，只需添加此内容即可.

window.onbeforeunload = null will clear it. Just add this before you try to redirect the user anywhere.
