Javascript窗口onbeforeunload事件问题 [英] Javascript Window onbeforeunload event issue

问题描述

你好朋友，

在我当前的项目之一中，我正在使用window.onbeforeunload事件检查一些值.如果选择停留在此页面上"，则需要在此操作过程中将值(如果有任何值更改)重置为原始值，但我没有得到如何执行此操作.有什么方法可以找到离开此页面"和停留在此页面"对话框的返回值吗?

例如:有一个下拉列表，其值为A，B，C.它的初始值为A，在工作期间，我将其更改为B并关闭了该窗口，但未保存该值.如果我选择停留在此页面上，那么我想将下拉列表的值重置为A.这怎么可能?

任何帮助将不胜感激.

亲切的问候，

Hello Friends,

In one of my current projects, I am using window.onbeforeunload event to check some values. I need to reset the values (if any value changed) to original values during this operation if I select "Stay on this page", but I am not getting how to do this. Is there any way to find a return value of "Leave this page" and "Stay on this page" dialog box?

For example: There is a dropdown which is having values A,B,C. Its initial value is A, during the work, I changed it to B and closed the window without saving that value. If I select stay on this page, then I want to reset the value of dropdown to A. How is this possible?

Any help will be appreciated.

Kind Regards,
Jagjot
