validate text field as user types

[droidus]

I am trying to validate a text field content as the user types, instead of when they click out of it. here is what i had before

onblur="javascript: validate(this.value, this.id, 1);"

then i tried this

onkeydown="javascript: validate(this.value, this.id, 1);"

here is some of the function

function validate(input, name, step) {
 if(step==1) {
 if(name=='name') {
 if (input==null || input=='') {
 document.getElementById('nameDiv').style.visibility='visible';
 document.getElementById('next').disabled='disabled';
 return false;
 } else {
 document.getElementById('nameDiv').style.visibility='hidden';
 var emailField = document.getElementById('email').value;
 if(emailField!="" && emailField!=null) {
 document.getElementById('next').disabled='';
 }
 }
 }
//and so on..

and...?

I think onkeyup would make more sense, considering...

[droidus]

sorry. i would like to validate the form as the value changes as the user types in the text field. no when they click out of the field.

agreed with xelawho, onkeyup is what you need.
