新元素的onLoad，委托/开启？ [英] onLoad of new element, delegate/on?

问题描述

我正在尝试在动态加载的元素（ .this_button ）上运行函数。我使用以下代码：

Im trying to run a function on an element (.this_button) that is being loaded dynamically. Im using the following code:

$(function(){
    $("body").on("load", ".this_button", function() {
         console.log("its been loaded");
    });
});

我尝试了 delegate ，但是它说弃用了 on 。例如，在文档已加载10分钟后，可能会推送某些元素。如何连续检查元素 .this_button 是否已进入正文？

I tried delegate, but it says its been deprecated in favor of on. Some elements might be pushed, say after the document's been loaded for 10 minutes already. How can it continually check if an element .this_button has entered the body?

谁知道为什么这不起作用？

Anyone know why this isnt working?

推荐答案

来自文档：

在所有浏览器中，加载，滚动和错误事件（例如，在元素上）不会冒泡。[...]此类事件不支持与委托一起使用，但是可以将事件处理程序直接附加到生成事件的元素上时使用。

"In all browsers, the load, scroll, and error events (e.g., on an element) do not bubble. [...] Such events are not supported for use with delegation, but they can be used when the event handler is directly attached to the element generating the event."
