I was usinig JSF 2.0, richfaces, and a4j in my development. I have a radio button group that consist of 3 radio button, and there is a inputtextbox next to each of the radio button, just like the layout shown below:
radio button A | input textbox A
radio button B | input textbox B
radio button C | input textbox C
Whenever there is a focus on textbox, can this be done using ajax to update on radio button selection? E.g. when focus on input textbox B, then radio button B will be selected. May I know how this can be done?
There are many ways to this, first using plain javascript and using ajax on jsf or richfaces components.
You can try using a4j:ajax nested inside your h:inputText and fire it whenever there is focus on your textbox.
<h:selectOneRadio value="#{bean.value}" id="radio" />
<h:inputText id="input" value="#{bean.textValue}" >
<a4j:ajax event="onfocus" render="radio" action="{bean.setRadioSelected}"/>
</h:inputText>
On the action method set the value of selected radio to true. Hope this helps.
