$(window).load()和$(document).ready()函数之间的区别 [英] Difference between $(window).load() and $(document).ready() functions

问题描述

jQuery中的$(window).load(function() {})和$(document).ready(function() {})有什么区别?

What is the difference between $(window).load(function() {}) and $(document).ready(function() {}) in jQuery?

推荐答案

• document.ready是一个jQuery事件，它在DOM准备就绪时运行，例如所有元素都可以找到/使用，但不一定所有内容.
• window.onload稍后(或在最坏/失败的情况下同时)在加载图像等时触发，因此，例如，如果您使用图像尺寸，则通常需要改用它.
• document.ready is a jQuery event, it runs when the DOM is ready, e.g. all elements are there to be found/used, but not necessarily all content.
• window.onload fires later (or at the same time in the worst/failing cases) when images and such are loaded, so if you're using image dimensions for example, you often want to use this instead.
