问题描述

我有一个要确认的链接.我正在使用javascript confirm()方法.但是，当用户单击取消"时，使链接不起作用的唯一方法是使用return false;.这是正确的方法(跨浏览器)吗?

I have a link that I would like to present with a confirmation. I am using the javascript confirm() method. But the only way for me to get the link to not work when the user clicks 'cancel' is to use return false;. Is that the correct way to do it (cross-browser)?

$('a.confirm').click(function() {
    if(confirm('Are you sure? This cannot be undone.')) {
        return true;
    }
    return false;
});

推荐答案

在事件处理程序上返回false等效于调用event.preventDefault和event.stopPropagation，您的代码应该可以工作，但是怎么办?

Returning false on an event handler, is equivalent to call both event.preventDefault and event.stopPropagation, your code should work, but what about:

$('a.confirm').click(function() {
  return confirm('Are you sure? This cannot be undone.');
});

如果用户取消确认，它将返回false.

It will return false if the user cancels the confirm...

在此处运行该代码段.
