Firefox Event Is Undefined ?
Mar 19, 2010
I have come across a problem that seems common with firefox and the use of event. I have a simple javascript function which trys to determine the element that an event was acted upon:
Code:
This is called on click of a input:
Code:
This seems to work correctly for every browser except firefox. A quick search online and all the fixes seem to include:
Code:
But when I debug this function, neither e or event are defined, am i overlooking something really obvious?

I have included a copy of my XML below.

is not assigning a value when the page is loaded in firefox but in IE it works perfectly.
Code:
function testAnswers(aqNow,review,toClose){
//alert("inside test answers");
var listQa = gid("listQuestions").value;

The following coding works in Konqueror 3.5.10 on Ubuntu 8.04.3 LTS but not on Firefox 3.0.10 Linux/3.5.7 XP, Opera 10.10 Linux or IE8 XP.I can't see why but it may be to do with the recursion (showtable calls onclick calls addit which calls showtable).Somehow it is not seeing the addit routine the second time round.It is meant just to add a line. Eventually it needs to be a complex table but this is for illustration. There are other ways to solve this but this would be the simplest - if it worked!What happens is that one line is added OK but then it chokes. This is what makes me think it is the recursion but I can't see otherwise how to make it write the updated text. I realise I should have a document.close() in it as well and I have tried adding <![CDATA[ ... ]]> as well.Other than in Konqueror, it gives an error message saying object not found (in IE8) or more explicitly:[code]

function doUnload()
{
if (window.event.clientX < 0 && window.event.clientY < 0)
{
alert("Window is closing...");
} }
I get window.event undefined by using
var evt =window.event? event : e I get e undefined
var evt =window.event? event : e
if (evt.clientX < 0 && evt.clientY < 0){
alert(evt.clientX +"Window is closing...");
}

I need an event that checks if the size of a DIV has changed. The "resize" event works in IE but not in FF. Or, more precisely, The "resize" event works in FF but NOT for resizing DIVs. Is there an event that works like the "resize" event but also can be used in with DIVs in FF?

After spending hours trying out many different examples that supposedly work with IE and FF, I've decided to post here :)
This is the code I'm using to catch the down arrow:
function is_int(event)
{
var Key = event.keyCode ? event.keyCode : event.which ? event.which :
[Code].....
And called using the following on the text input of a form field:
onKeyDown="is_int(event);"
This works in IE but still not in Firefox (3.5.7). Surprised as it has the .which in there - I thought this is what FF needed?

I am doing some showing and hiding of unordered lists for menus. I like CSS and so I swap the id of the unordered list to either show or hide the <ul>. The code works fine in Firefox but not in IE6. I start with the <ul> hidden using <ul id="SubMenu1Hide">. I attach the evens to the onmouseover and onmousout events. The bug happens in IE when I rollover the element with the event attached it does not show or disappear.
The <ul> seems to stay hidden like it is the default, it will never appear. Here is the weird thing. If I start with the id="SubMenu1Show" the menu shows as it is supposed to, stays visible when I mouseover and then disappears when I mouseout. It then continues to work as it is supposed to, appearing on rollover and disapearing on mouseout.
I want the submenus to all stack on top of each other on the page and be hidden by default then only show when you mouseover it's main menu heading. Here is the code:

My original idea of two trains, however pictural it was, appeared to be
wrong. The truth seems to be even more chaotic.
IE implements its standard down-up model: any mouse event goes from the
deepest visible element to the top. By carefully studying fromElement
and toElement properties, one can handle events on any point of their
way up.
NN/FF implements a "Russian hills" style: mouse events go first
up->down (window->deepest element), and right away after that it goes
down->up (deepest element->window). On theory you can handle events
during any phase on any level. On practice this implementation has some
major flaws. I don't have NN handy right now, but in FF we have:

Code like :

I have a requirement to force the pageUp and pageDown keys to function the same as the arrowUp and arrowDown. I believe I'm ok with IE but have issues with setting the value for FireFox ...specifically line: evt.which=38; and line evt.which=40; -the "which" seems to only have a getter-
try{
if (window.document.addEventListener) {
window.document.addEventListener("keydown", reviseKeyFunctions, false);
}else{

I am successfully using this code to cause an event to fire when the user clicks inside any of the text inputs in my form:
Code:
govindaAddEventHandler(document.getElementById("input_" + arrWhichFieldsFilterable[i]),"click",getMouseCoords); // govindaAddEventHandler(obj, eventName, handler)
...which relies on this:
Code:
function govindaAddEventHandler(obj, eventName, handler) {
if (document.attachEvent) {
obj.attachEvent("on" + eventName, handler);
[code]....
The problem occurs when I change it from an on"click" event to an on"focus" event. In the latter case (onfocus) it does not work on Firefox, but only in IE8. Why is that? How can I add an event handler for onfocus in firefox?

Here is an answer for those who are looking for a keystroke evaluation
script that works in Internet Explorer (IE 5.5, 6.0, 7.0 for PC--IE
4.0, 5.2 for Mac), Mozilla Firefox (Windows, Linux, and Apple
Macintosh), Safari, Opera, and other off-brand web browsers.
I have gone through many groups trying to find code that didn't break
in Firefox--yet still worked in other browsers. Although many people
give input on this topic, few are correct in their handling of the
events to give the correct results across the board.
I am a Webmaster, and although I have worked with much JavaScript, I do
not claim to be an expert on this topic--so feel free to post any
improvements that you can make.
Here's the test code, this snippet designed to force numeric-only input
in any browser, with the exception of a couple keys that are still
needed for form navigation (such as Tab--although this can be tailored
to your needs by adding more exceptions):
---SNIP_01---
<script language="JavaScript">
function CheckNumericKeyInfo($char, $mozChar) {
if($mozChar != null) {// Look for a Mozilla-compatible browser
if(($mozChar >= 48 && $mozChar <= 57) || $mozChar == 0 || $char ==
8 || $mozChar == 13) $RetVal = true;
else {
$RetVal = false;
alert('Please enter a numeric value.');
}
}
else {// Must be an IE-compatible Browser
if(($char >= 48 && $char <= 57) || $char == 13) $RetVal = true;
else {
$RetVal = false;
alert('Please enter a numeric value.');
}
}
return $RetVal;
}
</script>
---END_01---
This function would then be called as follows:
---SNIP_02---
<input type="text" name="over_figure" id="over_figure" size="5"
onKeyPress="return CheckNumericKeyInfo(event.keyCode, event.which);"
value="">
---END_02---
I have personally tested this on PC, Mac, and Linux systems in every
Web browser that I can get my hands on. It's far easier than the other
scripts that I've found, and you can just add "alert('keyCode: ' +
$char)" to find any other keycodes you might want to allow if you don't
know them off-hand. Obviously there is room to add a larger exception
list if you have need of it, and it might be better to just set $RetVal
to TRUE in the else and add an else if for IE, but my use didn't
require it.
I hope it saves someone some time!

I have the following question: What event could be or is triggered when someone fills in a inputfield using the autosuggest that is build in in browsers? Like for example my email that always comes back on email input fields. I have tried the change and keyup event but they don't work. What event could be or is triggered when someone fills in a inputfield using the autosuggest that is build in by browsers.
