PHP，HTML，Javascript执行顺序 [英] PHP, HTML, Javascript execution order

问题描述

我有一个test.php文件，这个文件包含一些PHP代码，HTML元素和一些内部的JavaScript以及一些外部的JavaScript包含。

我想知道哪个是首先加载或执行。

PHP或HTML或JavaScript？我想知道执行顺序。

您的回答非常感谢，对我和其他人也非常有帮助。

PHP首先运行并构建页面。

浏览器加载结果HTML（任何发现的JavaScript都会立即执行）

任何绑定到DOM ready或load event的JavaScript都会被执行一旦读取完整个HTML并分别加载所有对象。

I have a test.php file and this file contains some PHP code, HTML elements and some internal JavaScript and some external JavaScript include.

I want to know which is first to load or execute.

PHP or HTML or JavaScript? I want to know execution order.

Your answers are greatly appreciated and very helpful to me and others also.

解决方案

Pragmatically speaking, this is the typical order:

• PHP runs first and constructs the page.
• The browser loads the resulting HTML (any JavaScript found gets executed immediately)
• Any JavaScript that was tied to the DOM ready or load event gets executed once the whole HTML is read and all objects are loaded respectively.
