Checkboxes created using Javascript DOM not available in $_POST

[Sebarry]

Hi,

I have a Javascript function that creates a number of checkboxes dynamically using document.create Element. The checkboxes are created fine but even when they are checked they don't appear in $_POST in Internet Explorer. The same code works fine in Firefox and I can get the details of the checkboxes that are checked. Does anyone know of any problems with checkboxes in IE?

Thanks,

Sean

Heya, Sean.

Make sure you're attaching the checkboxes to an element inside the form.

For example:

function addCheck()
{
    var newCheck = document.createElement('input');
    .
    .
    .
    document.getElementById('insertHere').appendChild(newCheck);
}
 

If insertHere is here:

<form ... >
    .
    .
    .
</form>
 
<div id="insertHere"></div>
 

then the new checkboxes will not be submitted with the form. But if insertHere is here:

<form ... >
    .
    .
    .
    <div id="insertHere"></div>
</form>
 

The new checkboxes will be submitted.

Yep thought of that but it's definately not that. I don't understand why it works in Firefox but not IE.

var cb = document.createElement( "input" );
cb.type = "checkbox";
cb.name = htmlIdName;
cb.id = htmlIdName;
cb.value = xmlOptions[i].getElementsByTagName('id')[0].firstChild.data;
subDiv.appendChild( checkBoxName );
subDiv.appendChild( cb );
subDiv.innerHTML += "<br />";
 

Like I said when I put in an alert I can print out the value and checked status of my checkboxes but even when they're checked they don't appear in $_POST.

It's strange and frustrating.
