Hello Everyone
It's about 12 months since I used Tapestry but its good to be back :-) I'm
currently writing an Ajax based order form for a client but I've hit a
little problem. Basically I have a series of blocks which are used to
represent 'pages' in the order form i.e. I have a block for product
selection one for shipping address etc. As the user moves through the
checkout process the different blocks are rendered inside a zone:
Order.java:
@Component(parameters={"value=order.techFirstName"})
@Property
private TextField techFirstName;
@Component(parameters={"value=order.billingFirstName"})
@Property
private TextField bilingFirstName;
@Inject
private Block productSelection;
@Inject
private Block userDetails;
Object onSuccess() {
...
return new MultiZoneUpdate("orderForm", userDetails);
}
Order.tml:
<t:zone tid="orderForm">
<t:delegate to="productSelection" />
</t:zone>
<t:block t:id="userDetails">
<t:form>
<t:textField t:id="techFirstName" />
<t:textField t:id="billingFirstName" />
...
</t:form>
</t:block>
This is all working nicely but I now need to get the clientId of the
techFirstName element which in rendered inside the userDetails block. I'm
looking to perform a client side copy of the techFirstName element to
another form element within the block. My question is where do I put the
call to ${techFirstName.clientId} ? If I create a javascript function
outside the block getClientId returns null because the block hasn't yet been
rendered. If I put the javascript function inside the block it doesn't get
called. i.e. this doesn't work:
<t:block t:id="userDetails">
<t:form>
<t:textField t:id="techFirstName" />
<t:textField t:id="billingFirstName" />
<input type="checkbox" onclick="copyDetails()" />
<script type="text/javascript">
function copyDetails() {
var techFirstNameElementId = '${techFirstName.clientId}';
...
}
</script>
</t:form>
</t:block>
when i check the box i get an error because copyDetails() isn't defined
Does anyone know what is the best way to get a clientId for an element which
is rendered via Ajax?
Many Thanks
Toby
