PRB: Disabled Form Elements Are Not Submitted (287738)

SYMPTOMS

When you submit an HTML form that contains disabled elements, the disabled elements are not submitted with the rest of the form elements. In addition, in your server-side form processing code, you may not receive name/value pairs for any disabled elements that are located on your form.

MORE INFORMATION

The following sample code illustrates how to programmatically create new elements to submit the values of disabled elements through script in Internet Explorer 5.0 or later:

<HTML>
<BODY>
<SCRIPT LANGUAGE="JScript">
function doSubmit(theForm)
{
	var i = 0;
	for (i = 0; i < theForm.elements.length; i++)
	{
		if (theForm.elements[i].tagName == "INPUT" && 
theForm.elements[i].type == "text")
		{
			if (theForm.elements[i].disabled == true)
			{	
				var newElement;
				newElement = document.createElement("INPUT");
				newElement.type = "hidden";
				newElement.name = theForm.elements[i].name;
				newElement.value = theForm.elements[i].value;
				theForm.appendChild(newElement);
				newElement = null;
			}
		}
	}

	return true;
}
</SCRIPT>

<FORM onSubmit="doSubmit(this);" ACTION="formprocessing.asp" METHOD="POST">
 <P>First Name: <INPUT TYPE="TEXT" ID="firstname" NAME="firstname" VALUE="dan">
 <P>Last name:  <INPUT TYPE="TEXT" ID="lastname" NAME="lastname" VALUE="m" DISABLED>
 <P><INPUT TYPE="SUBMIT" VALUE="Submit">
</FORM>

</BODY>
</HTML>
