I dont know why my script is not working. I tried to get value of textbox in javascript but its not giving me a value. Value is shown as null.

//This is the code for my textbox



    <td> <input id=demo3 type=text size=25 runat=server/><a href=javascript:NewCal('demo3','ddmmmyyyy',true,24)>

     <img src=Resources/cal.gif width=16 height=16 border=0 alt=Pick a date></a>   </td>



//This is how I trid to access textbox

    exDateTime = document.getElementById('pCtrl').value;

but exDateTime is remains null.
I tried using other ways too, but nothing seen happening..

I don't think you are referring to the proper id.
Try document.getElementById(demo3).value

Or atleast paste the code where your pCtrl form field is.

EDIT : Make sure you set the value for the text box in html or using Javascript for example:

<input type='text' id='demo3' value='3'>

and then use document.getElementById(demo3).value to get the value, otherwise use javascript to assign the value and obtain the value at a later stage using the same.

I hope this helped you.
