jquery I am trying to append a hidden field to a hidden div from a button outside form

The problem is two-fold

1) camelcCase the appendTo function - appendTo()

2) you have multiple classes on your button - the first one takes precedence, so remove it
<input type="button" class="editincidentbutton" value="Edit incident" />

Does jQuery's `click()` method work on hidden form elements?

Yes, hidden inputs work with the click() method. You can't click on a hidden input element with your mouse, but you can execute the click event using the click method.

So, given this HTML:

<form>
    <input type="hidden" name="input1" id="input1" value="Yes">
</form>

You can assign a click handler:

$('#input1').click(function () {
    //do something
});

and invoke the click event:

$('#input1').click();

See http://jsfiddle.net/jhfrench/v6LUd/ for a working example.

How to add a hidden list of IDs to a form in Javascript?

I am not sure if I understand your question correctly, so I may just be guessing here.

Try adding multiple hidden inputs with a name such as ids[] so that they will be posted to the server as an array.

Example:

<form action="" method="post">
    <input type="hidden" name="ids[]" value="123">
    <input type="hidden" name="ids[]" value="534">
    <input type="hidden" name="ids[]" value="634">
    <input type="hidden" name="ids[]" value="938">
    <input type="hidden" name="ids[]" value="283">
    <input type="hidden" name="ids[]" value="293">
    <input type="submit" value="Save this stuff">
</form>
