i want to change the colour of output text field when i check the check box. its working fine if instead of output i use inputext field but not working with out put text field.
this is the code snipt of jsp page

<af:panelFormLayout id="pfl3">
                                            <af:selectBooleanCheckbox label="Noun "
                                                                      id="sbc1" selected="true"/>
                                             <af:clientListener type="click" method="changeColor"/>
                                            <af:inputText label="test" id="it5"/>
                                            <af:outputText value="hello " id="ota"/>

                                        </af:panelFormLayout>

and this the jquery code
i tried all these ways but in vain

function changeColor() {
    if ($("input[name=sbc1]").val() != null) {
       if (($("input[name=sbc1]").is(':checked') == true )) {
            $("input[name=it5]").css("color", "magenta"); // works because it5 is input field

            // does not works because ota is output field
            $("input[name=ota]").css("color", "orange");
            $("ota").css("color", "green");
             $("input[name=ota]").css("color", "magenta");
            document.getElementById("ota").inlineStyle.color="blue";
             $("#ota").css("color", "magenta");
             $("#ota").val("something")
        }

        else {
            $("input[name=it5]").css("color", "green");// works
            //does not work
            $("#ota").css("color", "green");
            $("ota").css("color","red");
            $("#ota").css("color","red");
           document.getElementById('ota').style.color = "green";
        }
    }
}

It would help to see the actual HTML that is received by the browser rather than the jsp code. Load the page right click view source.

well the source page is kind of wierd

Ok, hmm... i wasnt expecting there to only be javascript.

So when working with JavaScript/jQuery its important to know what elements are going to be avaiable to work with. The reason why i had asked for the HTML was to see what elmenets are actually there and what their IDs are. I dont know JSP, but in ASP.NET, the controls render as HTML elmenets and the IDs are generated by asp.net unless you include a parameter to make the IDs static in nature. Not sure if this also occurs in JSP.

So when you mention... not working with out put text field., there is no such things as an output textfield in HTML. your JSP code will take your <af:outputText /> control and convert it to HTML. What does it convert it to is the question... and what ID does that element have is the second question.

in <af:outputText value="hello " id="ota"/> isn't the id is ota ?
cant i access this element by using this id ?

Ok, so that was my point in my last post. I am not familiar with JSP, but in ASP.NET, even though the control is set to an ID="ota", this will not be the ID when the control is rendered as HTML. To do it in asp.net, you would have to add the attribute ClientIdMode="Static". I am going to assume there is an equivalent in JSP? That's the only idea that comes to mind at this moment.

The thing is that any server side scripting language that has their own controls... these controls must be converted to one or more HTML elments. The client browsers don't recognize what an output control is. The other way to verify is to see the HTML that is rendered which you say you were unable to see.
