如何检查脏标志 [英] How to check for dirty flag

问题描述

我想知道如果用户选择从中导航页面，检查页面是否脏的最佳方法是什么。例如，有一个注册表格，用户输入他的所有信息。然后不小心点击链接从中导航。

I was wondering what is the best way of checking if a page is dirty if a user chooses to navigate it from it. For example, there is a registration form and the user enters all his information. Then accidentally clicks on a link to navigate from it.

我在网上发现了这一点，如果一个人对任何表单输入值进行更改，它会检查页面是否脏。

I found this on the web where it checks if a page is dirty if a person makes changes to any of the form input values.

<script type="text/javascript">
var isDirty = false;
var msg = 'You haven\'t saved your changes.';
$(document).ready(function(){
    $(':input').change(function(){
        if(!isDirty){
            isDirty = true;
        }
    });
    window.onbeforeunload = function(){
        if(isDirty){
            return msg;
        }
    };
});
</script>

所以这很好用。但是如何排除某些弹出窗口链接？有没有更好的方法呢？

So this works great. But how do I exclude some links that are pop-ups? Is there a better way of doing this?

推荐答案

你应该在这些输入上添加onclick事件监听器并return false;
类似

You should add onclick event listener on these inputs and "return false;" Something like

$('a.className="popup"').onclick = function(){return false};

或

< a href = ＃onclick =return false;>文字< / a>

<a href="#" onclick="return false;">Text</a>
