Let's consider this simple code:
<h:form id="myForm">
<h:inputText id="myInput">
<a4j:support event="onchange" actionListener="#{myBean.doSomething}"/>
</h:inputText>
</h:form>
this will generate the following HTML code:
<input id="myForm:myInput" type="text" name="myForm:myInput" onchange="A4J.AJAX.Submit(...)" />
Now, I just add something in the onchange
event of my <h:inputText>
:
<h:form id="myForm">
<h:inputText id="myInput" onchange="alert('foobar');">
<a4j:support event="onchange" actionListener="#{myBean.doSomething}"/>
</h:inputText>
</h:form>
This will generate the following HTML code:
<input id="myForm:myInput" type="text" name="myForm:myInput" onchange="alert('foobar');" />
As you can see, the Ajax code is not added anymore. This is a really strange behavior as far as I am concerned. Why the <a4j:support>
does not attach the Ajax call if the event is already defined in the input field?
So my question is how to make the <a4j:support>
working on an event
that is already defined in the input
? Of course, the solution must run both the Javascript code defined in onchange
and the Ajax call.
In others words, I would like to have the following HTML:
<input id="myForm:myInput" type="text" name="myForm:myInput" onchange="alert('foobar'); A4J.AJAX.Submit(...)" />
I am using Richfaces 3.3.2 and JSF 1.2
EDIT
Of course, I can move the onchange
Javascript code in the onsubmit
attribute of the <a4j:support>
, doing something like that:
<h:inputText id="myInput">
<a4j:support onsubmit="alert('foobar');" event="onchange" actionListener="#{myBean.doSomething}"/>
</h:inputText>
But is it the only way??
