message in xmlhttprequest

[scriptwriter]

Hi,
I have value in jsp, i want it to be displayed in jsp using xmlhttprequest.

I did inside xmlhttprequest the following code

alert("message"+document.getElementById('msg').value);
document.getElementById('msg').innerHTML=document. getElementById('disablebutton').value;




alert message says undefined.

Any suggestions?
