Solution 2

You should build your last part from your key string dynamically like in the next example:

for( var  i = 1; i<4;i++)
{
 var uiElement=document.getElementById("_ctl1:PXP__APRSL_QSN_" + i);
 if (uiElement && uiElement.value == "") {
         uiElement.value = "Yes";
     }

}

Your method, that integrate my solution is OK now.
PS: When you will test it in your browser do not forgot to clear the browser cache before!

Maybe the ID used in your code does not exist!
You could improve your code like in my update (see my update in my solution!).

Master Vinu 21-Mar-14 4:34am

its give error object required

Raul Iloc 21-Mar-14 5:22am

You did you not use my update, se above in my solution!
Maybe the ID used in your code does not exist and you should manage also this case. But other solution could be to use jQuery in place of javascript to make shore that you select the UI controls that you need.

Master Vinu 21-Mar-14 5:46am

raul@ pls chk the updated question ..so you will get better idea of my requirement.
thx in advance

I gave you a solution to your code (optimization of the initial code by using for), but now you have problem in the accessing the controls from your page, so there could be the problem. Note that in your JS method you need only the second parameter (lang) and the entire "var AppQues=...; part could be deleted!
Can you update your question with me some details about your web page type (ASPX, HTML, CSHTML, etc), and the HTML code part from your page related with this questions, to can see their IDs for example!
