How to bind .hover() to dynamically created "li" elemtent?
提问by Tadas V.
All the solutions I was able to find suggests to use .live()method. But as of today it is deprecated.
我能找到的所有解决方案都建议使用.live()方法。但从今天起，它已被弃用。
.hover()works perfectly on "li" elements not created dynamically. But once I append new "li" .hover()is not triggered at all.
.hover()完美适用于非动态创建的“li”元素。但是一旦我追加新的“li”.hover()就根本不会被触发。
Anybody has figured this one out?
有没有人想过这个？

The "hover" event has been deprecated with delegated event handling such as .on()per the .on()jQuery doc pages.
“悬停”事件已被委派事件处理弃用，例如.on()每个.on()jQuery 文档页面。
Instead, you need to use .on()delegated event handling with mouseenter and mouseleave and an event handler for each.
相反，您需要使用.on()带有 mouseenter 和 mouseleave 的委托事件处理以及每个的事件处理程序。
For example:
例如：
$(document).on("mouseenter", "li", function() {
// hover starts code here
});
$(document).on("mouseleave", "li", function() {
// hover ends code here
});
In your real code, you would select a static parent object that is much closer to the dynamic litags than the documentobject for better performance.
在您的实际代码中，您将选择一个li比document对象更接近动态标签的静态父对象，以获得更好的性能。
