(Redirected from ZUML Reference/EL Expressions/Implicit Objects/forEachStatus)
forEachStatus – ForEachStatus
The status of an iteration. It is an instance of ForEachStatus. ZK exposes the information relative to the iteration taking place when evaluating the iterative element.
<listbox width="100px">
<listitem label="${forEachStatus.index}: ${each}" forEach="Best, Better, Good"/>
</listbox>
Note: forEachStatus.index
is absolute with respect to the underlying collection, array or other type. For example, if forEachBegin
is 5
, then the first value of forEachStatus.index
will be 5
.
To retrieve the information of the outer iterator if an iteration is nested, you could use ForEachStatus.getPrevious().
<listbox forEach="${matrix}">
<listitem label="${forEachStatus.previous.each.label}: ${each}" forEach=${each.items}/> <!-- nested-->
</listbox>
ForEachStatus.getEach() has beenDeprecated Since 8.0.0 and removedSince 10.0.0, please use ForEachStatus.getCurrent() instead. For example, replace ${forEachStatus.previous.each.label}
with ${forEachStatus.previous.current.label}
.
