【zk开发】多功能el函数库 zktools.jar

下面演示将composer,window,等注册为spring bean，然后在zk中使用

1,依赖jar，字符串操作依赖commons-lang2.5.jar，使用spring功能依赖 zkplus.jar

2,spring注册bean，必须是 scope="prototype"

 <bean id="loginController" class="org.zkoss.zk.ui.util.GenericAutowireComposer"  scope="prototype">
 </bean>
 <bean id="loginController2" class="org.zkoss.zul.Window"  scope="prototype">
 </bean>

3,在*.zul文件头部添加

<?taglib uri="http://www.zkoss.org/zktools/zktools" prefix="z"?>

4，使用

 

Xml代码  

1. <window id="loginWin" xmlns:w="client" xmlns:n="native" xmlns="http://www.zkoss.org/2005/zul" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
2.  xsi:schemaLocation="http://www.zkoss.org/2005/zul http://www.zkoss.org/2005/zul/zul.xsd"  
3.  use="${z:ctrl('loginController')}"  
4.  apply="${z:ctrl('loginController2')}">    
5. </window>  
6.   
7.    

<window id="loginWin" xmlns:w="client" xmlns:n="native" xmlns="http://www.zkoss.org/2005/zul" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.zkoss.org/2005/zul http://www.zkoss.org/2005/zul/zul.xsd"
 use="${z:ctrl('loginController')}"
 apply="${z:ctrl('loginController2')}"> 
</window>

 

 

 

Xml代码  

1. <row>  
2.     <cell>  
3.         开始日期   
4.     </cell>  
5.     <cell>  
6.         <datebox format="yyyy-MM-dd" id="dtBegin" mold="rounded"
