I have introduced a check box only if the check box is clicked only then the second text box has to be populated how can i check everytime whether the check box is clicked or not?

Use the checked property of the checkbox.

I have used this
if(document.get ElementById("th ird").checked== true) but its not working can somebody tell me the reason??

Use a button or onkeyup (as you had earlier) to call the function, not onclick on the checkbox.
