create new input field with javascript

[mikawhat]

I'm creating a new input field with javascript, however i'd like to put it on a specific place, like below a similar field. Is there a way to do this?

my code is:

var input = document.createElement("input");
input.setAttribute("type", "file");
input.setAttribute("name", "img"+img);
input.setAttribute("id", "img"+img);
input.setAttribute("value", "");
input.setAttribute("style", "font-size:10px");
input.setAttribute("size", "50");
document.getElementById("form1").appendChild(input);

The DOM interface says that nodes have an insertBefore() method. foo.insertBefore(blah) inserts the node "blah" immediately before the node "foo". You want after, so

1. Use foo's nextSibling property (The DOM interface says it has that, too) to see if it has a next Sibling.

2. If it does, then use insertBefore() to insert your new node immediately before that.

3. If it doesn't, then foo must be the last child of its parent, and calling fop.parentNode.appendChild(blah) (yes, DOM says foo will have a parentNode property) would achieve the same effect.

In short, you want to get familiar with DOM.
