但是可以想象一个MVC系统。您位于正文中，并尝试使用 $（document）.ready 。它不会工作，因为jQuery没有加载。那么什么？
编辑：所以
< body>
这里我需要jQuery。但它不会工作，因为它没有加载。那么如何解决这个问题呢？
< / body>
< script src ='jquery>
你似乎混淆了脚本声明的物理位置具有逻辑可用性。在jQuery加载后执行的任何脚本都可以使用jQuery，无论它是否由加载jQuery的标签在物理上看起来较高的标签加载。
according to this:

but lets imagine an MVC system. You are inside the body, and try to use $(document).ready. It wont work since jQuery is not loaded. Then what?
EDIT: so
<body>
here I need jQuery. But it wont works since its not loaded. Then how to workaround this?
</body>
<script src='jquery>
You seem to be confusing physical position of the script statement with logical availability. Any scripting that executes after jQuery is loaded has jQuery available, regardless of whether it is loaded by a tag that appears physically higher in the page than the tag that loads jQuery.
