提问by faressoft
Is $(document).ready() called after loading script js files in the body ?
$(document).ready() 在正文中加载脚本 js 文件后是否调用？
If I put $(document).ready() in the head in script element which take a callback function that using a functions declared in a file which its script element loaded in the body like that :
如果我将 $(document).ready() 放在脚本元素的头部，它采用一个回调函数，该函数使用在文件中声明的函数，其脚本元素加载到正文中，如下所示：
<!DOCTYPE HTML>
<html>
<script src="jquery.js" type="text/javascript"></script>
<script>
$(function(){
hello();
})
</script>
<head>
</head>
<body>
<script src="http://somewhere/helloFuncDeclaration.js" type="text/javascript"></script>
</body>
</html>
Is it a right way to do that and guarantee that the helloFuncDeclaration.js will be loaded before calling the function hello() ?
这样做并保证在调用函数 hello() 之前加载 helloFuncDeclaration.js 是一种正确的方法吗？

To be sure, use window onload handler:
可以肯定的是，使用窗口加载处理程序：
$(window).on('load', hello);
Or use it like this:
或者像这样使用它：
<script onload="hello()" src="http://somewhere/helloFuncDeclaration.js" type="text/javascript"></script>

To be sure , you can use window.load
可以肯定的是，您可以使用 window.load
$(window).load(function(){
hello();
})
The load event is sent to an element when it and all sub-elements have been completely loaded. This event can be sent to any element associated with a URL: images, scripts, frames, iframes, and the window object.
当一个元素和所有子元素都被完全加载时，加载事件被发送到一个元素。此事件可以发送到与 URL 关联的任何元素：图像、脚本、框架、iframe 和 window 对象。

$(document).ready()runs after all assets were loaded, so - yes
$(document).ready()在加载所有资产后运行，所以 - 是的
