Question

If am entering some values in text box it should be simultaneously displayed in other text box using html and js in the same page.

That is if i enter test in text box then the other text box should contain the alphabet test immediately.

Is that possible. If yes how?

kindly clarify.

thanks in advance

Answer 1

Use the onkeydown event, combined with a timer that will execute immediately afterwards:

textbox1.onkeydown = function () { 
    window.setTimeout(function () { textbox2.value = textbox1.value; }, 0);
}

Example

For Opera, you will need to use onkeypress to capture repeated input (holding the key down).
