Getting 'qva is undefined' error from java script.

Hi All,

I am trying to retrive Text of a TextBox object from a javascript function on a asp.net page. I have written the following code snipets :

<%@ Register Assembly="QlikViewWorkBench" Namespace="QT.QWW.WebControls" TagPrefix="qww" %>

<script type="text/javascript">

var obj;

function Init()

{

     obj = qva.GetQvObject("TX01", function () {});      

}

qva.BodyOnLoadFunctionNames.push("Init");

    function GetText()

    {

        var text = obj.QvaPublic.Data.GetSelected();      

       alert("the text value is: " + text);

    }

</script>

<input type = "submit" value = "HTML"    onclick="GetText()" />

At the compile time I am getting the error  :  'qva'  is undefined

Can any one pls. let me know what I am missing ?


Thanks,

Somnath.

If I try the code :

<%@ Register Assembly="QlikViewWorkBench" Namespace="QT.QWW.WebControls" TagPrefix="qww" %>

<script type="text/javascript">

   

function GetText()

    {

        var text = qva.GetQvObject("TX01", function () {});

        alert(text.Data.GetText());

      }

</script>

<input type = "submit" value = "HTML"    onclick="GetText()" />

I am not getting any error  at compilation time. But at run time on button click getting error : 'Data' is null or not an object

Pls. help.
