你怎么知道文件是否准备好了 [英] how do you know if document is ready

问题描述

我有一个生成HTML块的JavaScript。此脚本有时在运行时调用，有时在加载文档之前调用。我想要一个能够判断文档是否准备就绪的脚本。如果是，则生成HTML，否则，添加document.ready（）函数。什么是jQuery知道文档是否已被加载的最佳方式？

I have a JavaScript that generates HTML blocks. This script is sometimes called somewhere in run time, and sometimes before document is loaded. I want a script that is able to tell if document is ready. If so, generate the HTML, otherwise, add a document.ready() function. What is jQuery's best way to know if document has been loaded?

推荐答案

始终将该HTML生成代码包装在$中是安全的（文件）。就绪（）。如果文档已经准备就绪，则会立即执行新注册的$（document）.ready（）回调。

It's safe to always wrap that HTML generation code in $(document).ready(). If the document is already ready, a newly registered $(document).ready() callback will execute immediately.
