ASP.NET Controls In Java Script

Hi,

ASP.NEt Controls In Java Script without posting back to the server..

I need a solution for accessing the asp.net controls in Java script so that I can erase the values in the text box when the user clicks on RESET button without posting back to the server..
Urgent Please.......MY TL is on my neck...............................

Set autopostback to false for button then call a Script function and Change value to 0 through javascript. its Easy man... Enjoy Coding :)
