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

Question

Hi

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).
