javascript settimer broken FF 73.0

more options

I have the following Javascript code which has been working for over 10 years and still works on Chrome, but does not work on FF 73.0 on Ubuntu Linux.

```

/************************************************************************

*  timer														        *
*																		*
*  This timer is started whenever the user presses a key in the input	*
*  field and pops if 0.9 second passes without a new keystroke			*
************************************************************************/

var timer = null;

/************************************************************************

*  function onKeyDownName												*
*																		*
*  This method is called when a key is pressed in the Name field.		*
*  A timer is set so that when the user stops typing the selection		*
*  list is repopulated.												*
*																		*
*  Input:																*
*		event	if passed, event.keyCode identifies the key pressed		*
*				in older releases of Internet Explorer use window.event	*
************************************************************************/

function onKeyDownName(event) {

   if (timer)

clearTimeout(timer);

   timer	= setTimeout(update, 900);

} // function onKeyDownName

/************************************************************************

*  function update														*
*																		*
*  This method is called when the user stops typing to repopulate		*
*  the selection list based upon the current contents of the Name		*
*  field.  It is also the onchange method for the following fields:	*
*  'birthmin', 'birthmax', 'incMarried', 'includeParents',				*
*  'includeSpouse', and 'Sex', and it is called by the onchange		*
*  method for the field 'treeName'.									*
************************************************************************/

function update() {

   var	form	= document.nameForm;
   if (form)
   {		// form present

var url = "/FamilyTree/getIndivNamesXml.php"; ... code to complete url by appending values of elements from form // invoke script to obtain list of names for selection list HTTP.getXML(url, // see O'Reilly Javascript gotNames, noNames);

// clear out the old selection list while we are waiting var select = form.individ; select.options.length = 0;

// put a dummy entry at the top of the selection, otherwise // selecting the first name does not call onchange var name = '[choose an individual]'; var option = new Option(name, -1, false, false); option.innerHTML = '[choose an individual]'; select.appendChild(option);

   }		// form present
   else
       alert("nominalIndex.js:update: cannot find form");

} // function update ```


When I put alerts into nameOnKeyDown and update I see that nameOnKeyDown is called but update is never called.

This code has worked for over 10 years, and still is working today on Chrome, but the timer never pops on Firefox 73.0 on Ubuntu Linux 19.10.

Thank you for looking at my report.

This wasn't a developer question because I wasn't asking how to get the code working. It was a caution that I had observed a specific problem on a specific release of Firefox that was not observed on other browsers. However the problem has now gone away as mysteriously as it appeared with no changes to any of my code.
