From my reading of the HTML spec, it's not a bug, it's how the onchange event works.  The spec says:

The onchange event occurs when a control loses the input focus and its value has been modified since gaining focus

(My emphasis).

(http://www.w3.org/TR/html401/interact/scripts.html#adef-onchange)

When changing the control's value via script, the control never gets the focus, so implicitly never loses the focus, which is a prereq for the onchange event to fire.

The same thing happens if one changes a normal form input control via script.  No event fires.

I do however have an issue with the cfinput type datefield.

How do you disable Saturdays and Sundays?

In Flash form and Flex, we only use disabledDays=[0,6]

For example,

<cfinput
           type="datefield"

          id="valuationDate_txt"

          name="valuationDate_txt"
          mask="dd/mm/yyyy" width="50"
          value="#lsdateformat(now(),'dd/mm/yyyy')#"
          onFocus="valuationDate_txt.disabledDays = [0,6];">

How do we make the disabledDays=[0,6] work with the cfinput type datefield?

Thanks and regards.

This may not be the most elegant solution out there, but it works okay.

====== Javascript Code ======

i = 0;

function doSubmit(caldate) {

i++;

if (i>1) {

window.location = "index.cfm?caldate=" + document.getElementById('caldate').value;

     }

}

=====CFML Code ======

<cfform ... typical code here ....>

<cfinput type="datetime" id="caldate" ...typical code here .... />

<cfajaxproxy bind="javaScript:doSubmit({caldate})">

</cfform>

What this does is fires doSubmit each time the form controls are touched or the value is modified.  When this happens, it will increment i.  You will fire doSubmit twice (once to open the calendar and then once when a date is actually selected).  So you want to fire when i = 2 or when i > 1.
