i had to make myself get into the habbit of doing id's in inputs wether i needed them or not, because i do use them quite a bit in js for validation of input and it is easier to have them in there...

There is never any reason to use IDs for input validation.

Compare this code (just showing the code needed to access four form fields, no validation):

var fld1 = document.getElementById("field1");
var fld2 = document.getElementById("field2");
var fld3 = document.getElementById("field3");
var fld4 = document.getElementById("field4");

versus this:

var form = document.getElementById("myForm");
var fld1 = form.field1;
var fld2 = form.field2;
var fld3 = form.field3;
var fld4 = form.field4;

Using the form and field names produces shorter code *and* faster code.

What's the excuse for using IDs?
