Question

Update: Ok, I need to be shot. I left out a little bit of form code to cut down on the length of the post. Here’s the full code:

<form name="userupdate" id="userupdate" method="post">
<input type='hidden' name='username' id='username' value='andyd273' />
<input type='hidden' name='setusertype' id='setusertype' value='1' />
<table align="left" border="1" cellspacing="0" cellpadding="3" class="bodytext">
<tr><td>andyd273</td></tr>
<tr><td>
<input type='checkbox' name='DealerType[]' id='GM' value='1' /> GM<br>
<input type='checkbox' name='DealerType[]' id='Chrysler' value='2' /> Chrysler<br>
<input type='checkbox' name='DealerType[]' id='Ford' value='3' /> Ford<br>
</td></tr>
</table><br>
<input type='button' value='Save' onclick='javascript: formSubmit();' />
</form>

I figured I’d try something out, and removed the table stuff, just leaving the plain form inputs, and the checkboxes started working just like they do in Chrome.

So, new question: Why won’t serialize work in IE when the inputs are inside of a table?
Thanks to everyone that tried to help solve the first incomplete question!

Old question left for completeness:

I am trying to get a form to serialize. It works in Chrome and Firefox, but not in Internet explorer.
Example:

<input type='hidden' name='username' id='username' value='andyd273'>
<input type='hidden' name='setusertype' id='setusertype' value='1'>
<input type='checkbox' name='DealerType[]' id='GM' value='1' /> GM<br>
<input type='checkbox' name='DealerType[]' id='Chrysler' value='2' /> Chrysler<br>
<input type='checkbox' name='DealerType[]' id='Ford' value='3' /> Ford<br>

In Chrome I get:

Array
(
    [username] => andyd273
    [setusertype] => 1
    [DealerType] => Array
        (
            [0] => 1
            [1] => 3
        )

)

But in IE I only get:

Array
(
    [username] => andyd273
    [setusertype] => 1
)

So I’m not sure what needs to be done with it to make it work in IE.

Answer 1

jQuery’s serialize does not include unchecked checkboxes.

Check out this fiddle:

You can find more from the following question:

jQuery serialize does not register checkboxes

Ignore the code, wouldn’t let me post an answer.

$('#test').on('click', '#submit', validate);

function validate() {
    var data = $('#test').serialize();
    console.log(data);
