ExtJS 4学习
主要是选自《Ext js 权威指南》描述的是Extjs4的版本
模板代码如下：（略有改动，原因是当前文件目录下放置了extjs的包）

Ext.onReady(function() {
if (Ext.BLANK_IMAGE_URL.substr(0, 4) != "data") {
Ext.BLANK_IMAGE_URL = "./images/s.gif";
}
});
</script>

最后，转载一个查看extjs的工具类
Illuminations for Developers Keygen
这个注册工具来源于http://userscripts.org/scripts/show/103823本人稍作修改，以便工具能够独立运行。
并且修改C:\Documents and Settings\Administrator\Application Data\Mozilla\Firefox\Profiles\b4fc8mmf.default\extensions \[email protected]\content\native\mozilla \IlluminationModule.js里面的illumination_isTrial函数为
illumination_isTrial = function() {
return false;
}
将以下内容保存为keygen.html
