Hi,
I have a scenario to display some buttons based on an a condition from a Util Class. for example:
<zk if="${AppUtils.isColor('Green') == 'true'}">
<button
id="${greenButtonId}" label="${greenButtonLabel}"
forward="onClick=onGreenClick"/>
</zk>
Hi
please use xel method
.java
package org.zkoss;
import java.util.ArrayList;
import java.util.Collection;
public class AppUtil {
public static boolean isColor(String color){
return color.equals("green");
}
}
.zul
<?xel-method prefix="c" name="test" class="org.zkoss.AppUtil"
signature="java.lang.Boolean isColor(java.lang.String)"?>
<zk if="${c:test('green')}">
<button label="hello xel-method"/>
</zk>
