我在用 DirtyForms 和 $.blockUI 插件,后者可以在点击链接时更改页面(在我的应用程序中,有些页面需要几秒钟的时间才能加载,视觉反馈也很好)。

当我更改字段内容,然后单击任何链接时,dirtyforms都会被触发:但是当我取消进程以停留在页面上时, $.blockUI 开始游戏,导致页面卡住

$('form[method="post"]').dirtyForms();
$('a').on('click', function(){
	$.blockUI();
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.dirtyforms/2.0.0/jquery.dirtyforms.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.blockUI/2.70/jquery.blockUI.min.js"></script>

<p>Change the field content to activate DirtyForms, then click on the link.<br>
When the popup appears, click on "cancel" to stay on the page.<br>
Watch blockUI getting fired as the link is going to be followed</p>
<form action="#" method="post">
  <input type="text" name="username" required>
  <button type="submit">send</button>
</form>
<a href="https://google.com">click me after changing field content</a>

拜托,有什么解决办法吗?

stay.dirtyforms 和 afterstay.dirtyforms 事件,但没有效果。 defer.dirtyforms 似乎有效,但事件被触发了两次(我将 console.log() 我不确定这是不是一条路…

我已经修改了我的答案 :我已经添加了一些代码行,以首先禁用 onbeforeunload 对话框警报, taken from here . 在最后一个链接到一个答案与另一个想法,你可以尝试。

我的想法: 您必须阻止默认链接操作并使用$.blockui Modal Dialogs methods 若要打开自定义对话框,请捕获链接属性 href 从链接将其放在变量中,并将变量值用于 #yes 对话框的按钮。

看看这个解决方案是否能满足您的需要

/* beforeunload bind and unbind taken from https://gist.github.com/woss/3c2296d9e67e9b91292d */

// call this to restore 'onbeforeunload'
var windowReloadBind = function(message) {
  window.onbeforeunload = function(event) {
    if (message.length === 0) {
       message = '';
    };
  
    if (typeof event == 'undefined') {
       event = window.event;
    };
    if (event) {
       event.returnValue = message;
    };
    return message;
  }
};

// call this to prevent 'onbeforeunload' dialog
var windowReloadUnBind = function() {
    window.onbeforeunload = function() {
      return null;
   };
};

var linkToFollow; // href to follow

$('form[method="post"]').dirtyForms();

$('a').on('click', function(e){
        e.preventDefault();
        windowReloadUnBind(); // prevent dialog
	$.blockUI({ message: $('#question'), css: { width: '275px' } });
        linkToFollow = $(this).attr('href');
});

$('#no').click(function() { 
        $.unblockUI();
        return false; 
});

$('#yes').click(function() { 
        $(window.location).attr('href', linkToFollow); 
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.dirtyforms/2.0.0/jquery.dirtyforms.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.blockUI/2.70/jquery.blockUI.min.js"></script>

<p>Change the field content to activate DirtyForms, then click on the link.<br>
When the popup appears, click on "cancel" to stay on the page.<br>
Watch blockUI getting fired as the link is going to be followed</p>
<form action="#" method="post">
  <input type="text" name="username" required>
  <button type="submit">send</button>
</form>
<a href="https://google.com" class="link">click me after changing field content</a>
<div id="question" style="display:none; cursor: default"> 
    <h6>Would you like to contine?.</h6> 
    <input type="button" id="yes" value="Yes" /> 
    <input type="button" id="no" value="No" /> 
</div>

另一种观点来自另一个答案: 另一个想法是 jQuery.ajax({}) 返回值前调用 beforeunload as seen in this answer
