Changing a checkbox's state programmatically in dashcode

Question

Okay, so I'm trying to change a checkbox's state programmatically in dashcode. I've tried:

var checkbox = document.getElementById("checkbox");

// I have tried all the following methods.
checkbox.checked = false;
checkbox.selected = false;
checkbox.value = false;

Answer 1

Maybe:

checkbox.checked = "checked";

Then:

checkbox.checked = "unchecked";

Answer 2

checkbox.setAttribute("checked", "checked"); // set
checkBox.removeAttribute("checked"); // remove

Answer 3

Dashboard Widgets just run on WebKit technologies, so code valid for Safari should also be valid in Dashcode. Either of the following should work:

checkbox.checked = true;
checkbox.setAttribute("checked", "true");

The fact that they are not working indicates there is a problem elsewhere in your code. I would check the line

var checkbox = document.getElementById("checkbox");     

Correctly assigns an element to the checkbox variable. Also, check the id of your "checkbox" element is valid and correct (not a duplicate, doesn't have a typo, etc).

Answer 4

Hello! This question is one month old as I write this answer. It was probably already solved, but in any case I would like to add that if you are using Dashcode, the Checkbox part is a div which contains one label and one input, this one being the "real" checkbox.

If you inspect the html as it is loaded in Safari you will notice that "checkbox" is the type of the element.

Therefore the proper way to change the state of the checkbox would be, assuming "input" is its id (it could have a default number attached though):

document.getElementById("input").checked="true";

or whichever method you want to use.

The main point here is that you were trying to change the state of another div.

Hope it helps! Regards,
