(Firefox :: General, defect)

Windows Vista
Not set





(Reporter: lampacz, Unassigned)


(Whiteboard: [CLOSEME 2011-1-1])

User-Agent:       Opera/9.61 (X11; Linux i686; U; en) Presto/2.1.1
Build Identifier: FF 3.0.3

When trying send form data with ajax all selects are screwed (is not possible to change their value, after first select is not possible again to select another option) Happens only on vista (linux ok, other browsers ie, opera works ok)

Reproducible: Always

Steps to Reproduce:

<script type="text/javascript">

function getData() {
	var sData = '';
	var oForm = document.getElementById('jForm');

	for (var i = 0; i < oForm.length; i++)
		sData += (sData ? '&' : '') + oForm.elements[i].name + '=' + encodeURIComponent(oForm.elements[i].value);

	return sData; 

function _rpc() {
	try {
		return new XMLHttpRequest();
	} catch (error) {}
	try {
		return new ActiveXObject('Msxml2.XMLHTTP');
	} catch (error) {}
	try {
		return new ActiveXObject('Microsoft.XMLHTTP');
	} catch (error) {}
	return null;

function submitForm() {
	var sData = 'rSave=100&' + getData(); 
	var rpc = _rpc();
	rpc.onreadystatechange = function() {
		if (rpc.readyState == 4 && rpc.status == 200) {
			var x = document.createElement('div');
			x.innerHTML = rpc.responseText;
	};'POST', 'ffbug2.html', true);
	rpc.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
	rpc.setRequestHeader('Content-length', sData.length);
	rpc.setRequestHeader('Connection', 'close');

	<form action="" method="post" id="jForm">
		<select name="rF1">
			<option value="1">A</option>
			<option value="2">B</option>
			<option value="3">C</option>
		<select name="rF2">
			<option value="1">Z</option>
			<option value="2">Y</option>
			<option value="3">X</option>
		<input type="button" name="rSubmit" value="Submit" onclick="submitForm();">

file ffbug2.html:
<script type="text/javascript">
	alert('Response OK');

click on Submit button (you can choose other options than default) and you should get alert Response OK, then try change value of select. Is possible to drop down but selection is not acceptable and second selection of same select is not possible
Actual Results:  
unable to select another select option

Expected Results:  
able to select another select option
I confirm that happens also in latest FF 3.5.3
On windows XP and Windows 7. Didn't checked other operating systems.
Looks like this happens only if ajax loaded page has alert() in script. I had to rewrite my scripts to use custom alerts instead of default javascript alert() to be compatible with firefox. In other browsers all ok.
