how to reference the field name that tapestry automatically creates?
hello again,
I already ask this question yesterday, but I try to be more specific and
clearer this time (and I hope to get an answer, because I really run out
of time..)
this is my component:
<span jwcid="$content$">
<span jwcid="@Foreach" source="ognl:descLinkList"
index="ognl:doIdx" value="ognl:doUsrLnk">
<input jwcid="@TextArea" wrap="off"
style="visibility:collapse;" value="ognl:langRes[doIdx]" rows="2"
cols="20"/>
<a jwcid="@GenericLink" onClick="ognl:linkJS"
href="javascript:void(0)">xyz</a>
</span>
</span>
inside the onclick javascript handler from the GenericLink component I
have to reference the field name of the above TextArea field.
in this case it would be $TextArea, $TextArea$0, $TextArea$1 and so on...
but if my form contains more than one of this components, I can not
assume that.
how can I access the name of the TextArea field?
thanks for any help
andreas

that's a very good idea!
I have not thought about the 'id' as yet. I had just the 'name' in my mind.
thanks very much!!

One possible approach is to set the 'id' parameter of the TextArea to
anything you want, and then reference it from JavaScript in that way. It
could be the name of the component + a counter, for example -- that will
make it both unique and predictable.
e.g.
<input jwcid="@TextArea" .... id="ognl:textAreaId"/>
public String getTextAreaId()
{
...
}
Does this help?

thanks marilen,
I have to use the 'id' approach, because there is no way to create the
jwcid's dynamically.

If your javascript component is inserted after component which name you
need then it is possible to do something like:
<span jwcid="ta1@TextArea" .../>
<span jwcid="@Script" param="ognl:components.ta1.name" ..../>
this way you can pass the textarea name to the script. The name will
replace the ${param} in the script definition.
For more complicated examples you will need to use the id method
described by Mindbridge..
