Hi,
I have modified a xhtml task form generated by the Graphical designer plugin in
order to add a combobox component:
| <h:selectOneMenu onchange="updateTopic(this);" id="topicCombo"
value="#{ChooseTopicBean.value}" styleClass="combobox">
| value="#{ChooseTopicBean.items}"/>
| </h:selectOneMenu>
| </jbpm:datacell>
|
and defined apart a JS function called "updateTopic(ref)" which try to change
the value of another jsf component when select any of the combobox's options,
that is:
| <h:inputText id="inputTopic" value="#{var['topic']}" />
|
I don't know how to reference the inputText from my JavaScript function since
I've seen from the generated HTML page parsed by the browser that the
components/forms IDs are generated dynamically:
| <input id="j_id197:inputTopic" type="text" name="j_id197:inputTopic" />
|
So, I'll get an error if I try to reference as
"document.getComponentById('inputTopic')".
Where is the "j_id197" id name coming from? Is there any other way to reference
jsf components from Javascript?
Thanks in advance.
Cheers.
