Ext.js 完全独立于 jQuery，因此不以任何方式依赖 jQuery.不知道完全兼容"是什么意思，但您可以在同一页面上使用它们，因为它们不会相互干扰.

Ext.js is completely independent of jQuery and as such does not rely on jQuery in any way. Don't know what you mean by 'full compatibility' but you can use both on the same page as they don't interfere with each other.

由于 Ext.js 不使用 $ 函数，你甚至不需要做任何特殊的技巧来让它们一起工作，就像在 jQuery 中使用 Prototype 一样，例如.

As Ext.js doesn't use the $-function, you don't even have to do any special trickery to get them to work together, as is the case with using Prototype with jQuery, for example.
