Question

I have a page that contains a link like this:

<a href="" onclick="add()">new user </a>

When the user clicks the link, I add a new input field to the page. I would like to assign an ID to that input field. I can do this using Javascript:

var num=0;
function add(){
   num++;
   var input = document.createElement('input');
   input.setAttribute('ID',"input"+num);
}

This works; but my question is, is this the standard way, or is there a better way to do this, something that doesn’t use num, JS or jQuery?

Answer 1

You don’t need an ID on an input element. However you might be needing a name. If so, just use name = "input[]" – then on the server side you will get an array of values.
