extjs3.0 源代码研究 （序）

1.文件加载顺序

dojo有build.txt文件表明各个文件的加载顺序，js然后自动加载css.

而extjs是完全一次性加载所有的控件的,js的加载顺序见ext-3.0-rc1/source/ext.jsb,css加载顺序为/ext-3.0-rc1/resources/resources.jsb

2.不用iframe的方法：如果用.autoLoad url:‘filepath.jsp’ filepath.jsp可以不用加载 ext-all.js.

3.CDN:

. If you needed to use a build with no grid or tree support you would just paste the following:

<mce:script type="text/javascript" src="http://extjs.cachefly.net/builds/ext-cdn-7.js" mce_src="http://extjs.cachefly.net/builds/ext-cdn-7.js"><!-- // --></mce:script> <link rel="stylesheet" type="text/css" href="http://extjs.cachefly.net/ext-2.2/resources/css/ext-all.css" mce_href="http://extjs.cachefly.net/ext-2.2/resources/css/ext-all.css" />

For those of you that need the complete library and use ext-all.js and ext-all.css we have those available as well.

<mce:script type="text/javascript" src="http://extjs.cachefly.net/ext-2.2/ext-all.js" mce_src="http://extjs.cachefly.net/ext-2.2/ext-all.js"><!--
 
// --></mce:script>
 <link rel="stylesheet" type="text/css" href="http://extjs.cachefly.net/ext-2.2/resources/css/ext-all.css" mce_href="http://extjs.cachefly.net/ext-2.2/resources/css/ext-all.css" />
