如何使用JS / jquery确认何时离开页面 [英] How to use JS/jquery to confirm when navigating away from page

问题描述

我试图在用户试图离开时给出警告确认对话框...我有以下代码，但它不能正常工作......

  jQuery（窗口）.unload（function（）{
 var yes = confirm（你即将结束你的会话，你确定吗？）; 
 if（yes）{
 return true; 
} else {
 return false; 
} 
}）; 
  

弹出窗口很好但是当我点击否时，它仍会导航...... / p>

感谢您寻找......

解决方案

不需要JQuery：

  window.onbeforeunload = function（）{
 return你即将结束你的会话，你确定吗？ ？; 
}

I am trying to give an alert confirm dialog box when users try to navigate away...I have the following code but it doesn't quite work...

    jQuery(window).unload(function() {
        var yes = confirm("You're about to end your session, are you sure?");
        if (yes) {
            return true;
        } else {
            return false;   
        }
    });

The popup comes up fine but when I click "NO", it still navigates away...

Thanks for looking...

解决方案

No need for JQuery:

window.onbeforeunload = function() {
    return "You're about to end your session, are you sure?";
}
