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.
You can see the above code in action at https://www.jamescobban.net/FamilyTree/nominalIndex.php?name=allenby,%20a&treename=&lang=en
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.
