页面完全加载后如何执行功能？ [英] How to execute a function when page has fully loaded?

问题描述

我需要在页面完全加载时执行一些JavaScript代码。这包括像图像这样的东西。

I need to execute some JavaScript code when the page has fully loaded. This includes things like images.

我知道你可以检查DOM是否准备就绪，但我不知道这是否与页面完全加载时相同。

I know you can check if the DOM is ready, but I don’t know if this is the same as when the page is fully loaded.

推荐答案

这叫做onload。在DOM准备就绪之前，它已经出现了，并且实际上已经创建了DOM就绪，因为onload等待图像的确切原因。

That's called onload. It came waaaaay before DOM ready was around, and DOM ready was actually created for the exact reason that onload waited on images.

window.onload = function () { alert("It's loaded!") }
