Problem
Dynamically appended checkbox element does not appear checked despite setting the checked property state to true or "checked".

Browser
Internet Explorer

Example
The Javascript code:

Expand | Select | Wrap | Line Numbers

 var cb = document.createElement("input");

cb.type = "checkbox";

cb.name = "checkbox1";

cb.id = "cbID";

cb.checked = true;

obj.appendChild(cb);

Solution
Use defaultChecked instead of checked:

Expand | Select | Wrap | Line Numbers

cb.defaultChecked = true;

Alternative Solution
Set the checked state after appending the checkbox:

Expand | Select | Wrap | Line Numbers

 obj.appendChild(cb);

cb.checked = true;
