I am dynamically creating an input that is a checkbox like:

myINPUT = document.createElement("INPUT");
myINPUT.type = "checkbox";
myINPUT.id = myINPUT.name = "myck_box";
myINPUT.value = "Y";
myINPUT.checked = true;
myINPUT.disabled = true;

This works on my IE 6, Netscape 7.2, Firefox 1.0.3, Mozilla 1.7.3 :

var myDiv = document.getElementById('somediv');
var myINPUT = document.createElement("INPUT");
myINPUT.type = "checkbox";
myINPUT.id = "myck_box";
myINPUT.name = "myck_box";
myINPUT.value = "Y";
myINPUT.disabled = true;
myDiv.appendChild(myINPUT);
myINPUT.checked = true;

I see .... I have to check it after I create it, i.e. I can't create it
in the "checked" condition.

Thanks, let me try that

No, for IE you have to check it after you *add it to the document*,
Firefox is quite happy for you to check it anytime after it is
created.

Until the checkbox is added to the document (either by appending it
to an element that is part of the document, or adding its parent
element to the document), IE will not check it.

In either case you must create it first before you can do anything
with it - I suspect that will be true of all browsers.

Ok.

You can. When the checkbox is added to the document (or when the
document is (re)loaded or the form reset), its "defaultChecked"
property determines its initial checked status.

myINPUT = document.createElement("INPUT");
myINPUT.type = "checkbox";
myINPUT.id = myINPUT.name = "myck_box";
myINPUT.value = "Y";
myINPUT.defaultChecked = true;
myINPUT.disabled = true;

ciao, dhgm
