I have a form input that I am using for a list in dashcode. I'm trying to specify a specific item from my list so I can use the code below, but I don't know how.

function fadeout(event)
{
// Values you provide
var itemToFadeOut = document.getElementById("text2");   // replace with name of element to fade

// Fading code
var fadeHandler = function(a, c, s, f){ itemToFadeOut.style.opacity = c; };
new AppleAnimator(8500, 13, 1.0, 0.0, fadeHandler).start();}

When I run this it says the itemToFadeOut is null which I understand because the element doesn't have an Id, it is just a class. How do I a specific element from my dynamic list an id?

You don't provide any details of the list or how you expect to access it, so advice can only be general.

You can get a reference to a form control if you can get to the form and the control has a name. If the name is a valid identifier:

var control = form.elements.elementName;

or

var control = form.elementName;

Otherwise you can use:

var control = form.elements[elementName];

or

var control = form[elementName];

If you have more than one with the same name, you can use a numeric index:

var control = form[elementName][index];

or

var control = form.elements[elementName][index];

Or if you just know which one it is, you can get it by index:

var control = form.elements[index];

or 

var control = form[index];

If you want to give an element an id (or change its current ID), just assign a value:

element.id = 'whatever';

Does any of that help?

You can target a specific row element with the following syntax:

rows[i].object.templateElements.<NAME_OF_THE_ELEMENTS_CLASS>.style

where is the name that you gave it in the Dashcode GUI (but leave the _template appendix away) and i is the index of the specific row (you get the index in the prepareRows Function).

Example:

rows[0].object.templateElements.text1.style

where the automatic generated css classname for text1 is text1_template.

Hope it helps.
