ZK - Open Source Ajax Java Framework

Hi,
I didn't found any example about zk VALUE iteration on zul page...
-----------------------
int num=4
foreach < num > print <something> on zul page
-----------------------

It's possible?

THANK YOU!

byteo,

If I understand your question correctly, can use Expression Language (EL) to accomplish what you ask.  Here is an example:

<zk>
	<window title="ForEach example" border="normal" style="padding:25px;">
		<zscript>
			int[] values = {1, 2, 3, 4, 5, 6, 7, 8, 9 , 10};
		</zscript>
		
		<separator height="25px"/>
		<vlayout>
			<label forEach="${values}" value="${each}"/>
		</vlayout>
		<separator height="25px"/>
	</window>
</zk>

Be advised, however, that EL is only evaluated once and very early in the cycle.  As such, is is mainly appropriate for static types of data.  Otherwise, I'd encourage you to use something that takes a model (such as a grid or listbox).

Hope that helps,

thanks but my problem is:

int i=0
int value=4
while i<4
<print something>

Hmmm, I can't think of an easy way to do that in zul.  However, ZK can certainly handle it.  Here are a couple of very simple examples:

Executions

<zk>
	<vlayout id="myLayout"/>
	<zscript>
		<![CDATA[
		int i = 1;
		while (i < 4) {
			Executions.getCurrent().createComponentsDirectly("<label value='xxx' />", null, myLayout, null);
			i++;
		}
		]]>
	</zscript>
</zk>

appendChild

<zk>
	<vlayout id="myLayout"/>
	<zscript>
		<![CDATA[
		int i = 1;
		while (i < 4) {
			myLayout.appendChild(new Label("yyyy"));
			i++;
		}
		]]>
	</zscript>
</zk>

fine! thank you!

wow!!
