框架之Iterative Evaluation

默认的情况下，zk会将每一个元素实例化，如果你想生成组件的集合，那么就要使用foreach

 

<?page title="new page title" contentType="text/html;charset=UTF-8"?>

<zk>

<window title="new page title" border="normal">

<listbox>

<listitem label="${each } "  forEach="apple,banana,pear"></listitem>

</listbox>

</window>

</zk>

 

 

<?page title="new page title" contentType="text/html;charset=UTF-8"?>

<?xel-method prefix="c" name="getAllCustomers" class="com.jing.zk.Customer"

signature="java.util.Collection  getAll(java.lang.String)"?>

<zk>

<window title="new page title" border="normal">

<listbox >

<listitem label="${ each.name}" forEach="${c:getAllCustomers('*') }"> </listitem>

</listbox>

</window>

</zk>

 

 

 

<zscript>

contacts = new String[]{"王京晶","王伟","郭军"};

</zscript>

<listbox>

<listitem label="${each} " forEach="${contacts }"></listitem>

</listbox>
