美化prettyPrint（）函数未加载到内部<script> tag
[英]Prettify prettyPrint() function not loading inside <script> tag
问题描述
I'm using Googles prettify.js and prettify.css files hosting them myself. 
我正在使用自己托管的Google的prettify.js和prettify.css文件。 This is a javascript and css script that highlights source code snippets inside <pre> or <code> tags. 这是一个JavaScript和CSS脚本，突出显示<pre>或<code>标记内的源代码片段。 Doc can be found here: https://github.com/google/code-prettify/blob/master/docs/getting_started.md 可以在以下位置找到文档： https ： //github.com/google/code-prettify/blob/master/docs/getting_started.md
To initialize the script, it can to be called like this: <body onload="prettyPrint();"> which works fine. 要初始化脚本，可以这样调用它： <body onload="prettyPrint();">可以正常工作。
I don't want to add this attribute to all the <body> tags of my pages, instead i want to call it from a <script> tag inside the <body> , (for reasons a bit long to explain). 我不想将此属性添加到页面的所有<body>标记中，相反，我想从<body>内的<body> <script>标记中调用它（出于较长时间的解释）。 But this doesn't work. 但这是行不通的。
Here is the code: 这是代码：
<body>
<script type="text/javascript">
prettyPrint();
//document.write('doing something');//this line prints
</script>
...
The code snippet is not getting highlighted as it did when i called the function through <body onload="prettyPrint();"> but there is no error on the JavaScript console, and the line 'doing something' is printing. 代码片段没有像我通过<body onload="prettyPrint();">调用该函数时那样突出显示，但是JavaScript控制台上没有错误，并且'doing something'行。
How can i call this function from the <script> tag? 如何从<script>标记调用此函数？
EDIT 编辑
Even this is printing but still the syntax is not getting highlighted: 即使正在打印，但语法仍未突出显示：
<body>
<script type="text/javascript">
if(window.prettyPrint){
prettyPrint();
document.write('doing something');//this line prints
}
</script>

So, it has to be called using object.onload i don't really know why i just tried a lot of things and this worked. 因此，必须使用object.onload来调用它，我真的不知道为什么我只是尝试了很多事情而这行得通。 Actually it makes a lot of sense anyways. 实际上，无论如何，这很有意义。
<body>
<script>
window.onload=function(){prettyPrint();};
</script>
