Hello kundan_101,

This is a JAVA forum, not a JAVASCRIPT forum. They are 2 different languages.

I suggest you try - javascript forum - Google Search

When you say "it shows result in textbox but value autometically get refreshed." Do you want it to append the numbers into the textbox each time?

I'm not sure if something like this will work?!

document.form1.text1.value = document.form1.text1 + randomnumber;

thanks for reply!!!!!!!!!!!!!!
