我在弹出窗口中有一个表单，它由 AJAX 调用加载。它是使用form_forRoR 标签构建的。即使我没有修改其中的任何字段并尝试导航到另一个页面，chrome 也会显示以下警报。

Alert is displayed because somewhere on your code, you are overriding the window before unload event, and when you try to close the window, the event fires. Try disallow this event putting up this on your code:
显示警报是因为在代码的某处，您在卸载事件之前覆盖了窗口，并且当您尝试关闭窗口时，该事件会触发。尝试禁止此事件将其放在您的代码中：
window.onbeforeunload = null;

Set it to an empty function:
将其设置为空函数：
window.onbeforeunload = () => {}
window.onbeforeunload = () => {}
回答by Bowen Li
You can hook in any other function inside the beforeunloadhandler:
您可以在beforeunload处理程序中挂钩任何其他函数：
window.addEventListener("beforeunload", function(e){
yourCustomFunction();
});

Enclose your formtag inside divlike this:
像这样将您的form标签括在里面div：
<div class="col-xs-12 no-padding"><form role="form" class="form-horizontal pad10-top" id="" onSubmit="return false;">
...</form></div>
<div class="col-xs-12 no-padding"><form role="form" class="form-horizontal pad10-top" id="" onSubmit="return false;">
...</form></div>
