我正在使用 DirtyForms 和 $.blockUI 插件,后者在单击链接时更改页面(在我的应用程序中,某些页面需要几秒钟才能加载并且视觉反馈很好)。
当我更改字段内容然后单击任何链接时,会触发 DirtyForms:但是当我取消进程停留在页面上时,$.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>
请问有什么解决办法吗?
编辑:我也尝试过
stay.dirtyforms
和 afterstay.dirtyforms
事件,但它们没有效果。 defer.dirtyforms
似乎工作,但事件被触发两次(我放了一个 console.log()
来检查),我不确定这是要走的路...... 最佳答案
我已经编辑了我的答案:我添加了一些代码行来首先禁用 onbeforeunload
对话框警报 taken from here 。最后还有一个答案的链接,其中包含另一个您可以尝试的想法。
我的想法: 您必须阻止默认链接操作并使用 $.blockUI Modal Dialogs methods 打开自定义对话框,然后从链接中捕获链接属性 href
将其放入一个变量中,并使用变量值作为 #yes
按钮的对话框。
看看这个解决方案能否满足您的需求
/* 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);
});

<input type="button" id="yes" value="Yes" />
<input type="button" id="no" value="No" />
</div>
来自另一个答案的其他想法: 其他想法是在
jQuery.ajax({})
as seen in this answer 中的返回值之前进行简单的 beforeunload
调用关于jquery-blockui - DirtyForms 不能与 $.blockUI 一起正常工作,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/50627110/
