Question

我正在尝试使用Extjs 3.4.0实现简单的登录代码，给出了所有包含文件的绝对路径，仍然面临Ext未定义的错误。我正在使用firebug进行调试。

Ext.onReady(function(){
Ext.QuickTips.init();

// Create a variable to hold our EXT Form Panel.

首先包含适配器的脚本标签：

<script type="text/javascript" src="E:/SICSR/ext-3.4.0/ext-3.4.0/adapter/ext/ext-base.js"></script>
<script type="text/javascript" src="E:/SICSR/ext-3.4.0/ext-3.4.0/ext-all.js"></script>

请参阅示例：http://dev.sencha.com/deploy/ext-3.4.0/examples/grid/array-grid.html并查看 HTML 源（不是array-grid.js的源代码），特别是第38-43行：

<!-- ** Javascript ** -->
<!-- ExtJS library: base/adapter -->
<script type="text/javascript" src="../../adapter/ext/ext-base.js"></script>

<!-- ExtJS library: all widgets -->
<script type="text/javascript" src="../../ext-all.js"></script>
