推荐答案

ready 事件，而所有内容（例如图像）也已加载后， onload 事件发生。

The ready event occurs after the HTML document has been loaded, while the onload event occurs later, when all content (e.g. images) also has been loaded.

onload 事件是DOM中的标准事件，而 ready 事件特定于jQuery。 ready 事件的目的是它应该在文档加载后尽早发生，以便为页面中的元素添加功能的代码不具备等待加载所有内容。

The onload event is a standard event in the DOM, while the ready event is specific to jQuery. The purpose of the ready event is that it should occur as early as possible after the document has loaded, so that code that adds functionality to the elements in the page doesn't have to wait for all content to load.
