Get value of the outputtext in javascript and access to backing bean in Oracle ADF

Requirement -Get value of the outputtext in javascript and send it to backing bean in Oracle ADF
Solution – We will use clientListener to call java script function and Serverlistener for calling java function

Below is the code for accomplish this

– page code

    <af:outputText value="value outputText" id="ot32" clientComponent="true"
                    shortDesc="shortDesc">
        <af:clientListener type="mouseOver"
                method="customJsFunction"/>
        <af:serverListener type="mycustomserverEvent" method="#{OutputTextCase11.handleServerEvent}"/>                
    </af:outputText>
    <br></br>
    <af:outputText value="Init" shortDesc="shortDesc" id="ot1" clientComponent="true"/>

– find javascript function code

   var customJsFunction = function(event)
   {
      var exceptiondata = event.getSource().findComponent("ot32").getValue();
      AdfCustomEvent.queue(event.getSource(),
                       "mycustomserverEvent",
                       {param1:exceptiondata},
                       true);
      return true;
   }

– method in bean

  public void handleServerEvent(ClientEvent ce)
  {
    String param = (String)ce.getParameters().get("param1");
    RichOutputText outputText=(RichOutputText)ce.getComponent().findComponent("ot1");
    outputText.setShortDesc(param);
    outputText.setValue(param);
    AdfFacesContext.getCurrentInstance().addPartialTarget(outputText);
  }

Get the display value of selectonechoice or LOV in bean – Oracle ADF

I found one approach to get the display value of LOV in managed bean using  ADFUtils.evaluateEl method.

Say if you have a value change listener for an lov,  valueChangeEvent.getNewValue() gives the index of the value. To get the display value of the lov, use below logic  :

public void onDeptNameChange(ValueChangeEvent valueChangeEvent) {

Object deptNameAttribute = ADFUtils.evaluateEL("#{bindings.deptName.items['"+valueChangeEvent.getNewValue().toString()+

"'].label}");

String deptNameStr = deptNameAttribute .toString();  // This should have the selected display value of lov.

}

Say if you want to access the display value of LOV, in any other method, other than valueChange listener, then use below code :

Object deptNameAttribute = ADFUtils.evaluateEL("#{bindings.deptName.items['"+ADFUtils.getBoundAttributeValue("deptId")+"'].label}");

Here deptId is the code of this lov.  Hope this is helpful.
