这里有新鲜出炉的精品教程,程序狗速度看过来!

ExtJS Javascript库

ExtJS是一种主要用于创建前端用户界面,是一个基本与后台技术无关的前端ajax框架。


基础夯实一点,会有好处的,排错的时候就体现出来了,下面就Ext.Direct做一些排错笔记与大家一一分享,感兴趣的朋友可以参考下哈
偶泪滴嘎嘎,终于,终于完成了一部分ExtJS。
(基础夯实一点,会有好处的,排错的时候就体现出来了)
下面就Ext.Direct做一些排错笔记:

错误一
 
严重: StandardWrapper.Throwable

这是为什么呢?
答案:
@DirectFormPostMethod
这个不对,这个产生了上面的错误,改成: @DirectMethod
同时删掉,由@DirectFormPostMethod生成的输出:
 
import com.softwarementors.extjs.djn.config.annotations.DirectFormPostMethod; 

错误二

控制层出错,也就是逻辑上不对,我的函数里面要求传入的参数,和提交的参数不对,
放心,不是xml配置问题,是传入的参数问题。所以重点在参数上,也就是语法。

我的错误原因
Java要求传入的参数为两个:
 
public Info submitData(String name,String password) 

而我在ExtJS 中实际传入的参数是一个:
 
var params= username.getValue()+Password.getValue(); 
FormAction.submitData(params,function(result,e){} 

改写一下就行了:
 
FormAction.submitData(username.getValue(),Password.getValue(),function(result,e){} 

错误三

原因是里面没有这个类
com.softwarementors.extjs.djn.test.config.GsonBuilderConfiguratorForTesting
这个错误在web.xml里面,把它们删了就行了:
 
<init-param> 
<param-name>registryConfiguratorClass</param-name> 
<param-value>com.softwarementors.extjs.djn.test.servlet.config.RegistryConfiguratorForTesting</param-value> </init-param> 
<init-param> 
<param-name>gsonBuilderConfiguratorClass</param-name> 
<param-value>com.softwarementors.extjs.djn.test.config.GsonBuilderConfiguratorForTesting</param-value></init-param> 

大概就这三个,我的情况就是这样。
