Should this be triggered on pressing keys or on blur or when the text box value changes?

thanks for reply

i want it on textbox value change.

here i am entering the phone number on mouse click using javascript.

here 0,1,2,3...9 buttons using those i am entering the phone number.

there is no keyboard to enter the phone number because it's a touch screen application.

Trigger the Ajax function onchange which takes the inputs and passes them onto the server-side script to validate. That script only needs to return true/false. Depending on the response, you can redirect or stay on the same page.

See an example. You could also try some tutorials in the Offsite Links thread. Make an attempt. If you get stuck, post your code.
