Getting Textbox value in Javascript

Question

I am trying to get the value of the textbox in a javascript, but its not working. Given below is the code of my test page

<%@ Page Title=\"\" Language=\"V         


        

Answer 1

The ID you are trying is an serverside.

That is going to render in the browser differently.

try to get the ID by watching the html in the Browser.

var TestVar = document.getElementById('ctl00_ContentColumn_txt_model_code').value;

this may works.

Or do that ClientID method. That also works but ultimately the browser will get the same thing what i had written.
