I am trying to develop a Qwerty Shifter http:[url]....by handling keyboard events.I want to display a textbox and as user type any text it changes at once means as user types "a" it display "s" "b" changes "n"
for internet explorer I have script
function InputEventKeyPress(event){
window.event.keyCode = shifter (window.event.keyCode);[code].....
I'm trying to write a cross-browser (IE and firefox) event handler for
the mousewheel. Basically my web app is an image viewer, so if you
scroll "down" with the wheel the next image should be displayed and if
you scroll "up" the previous image should be displayed.
So far I have:
function handleMouseWheel(e)
{
if (!e) e = window.event;
if ( e.wheelDelta <= 0 || e.detail > 0) { changeImage(1); }
else { changeImage(-1); }
}
This code works in IE and in Firefox to the desired effect. The
problem I am having is with registering the event handler.
The following works for IE:
document.onmousewheel = handleMouseWheel;
And the following works for Firefox:
window.addEventListener("DOMMouseScroll", handleMouseWheel, false);
But when I add the firefox event handler to my code, IE chokes with an
error "Object doesn't support this property or method".
What do I need to do to "hide" the firefox event handler code from IE?
I have a document with a parent element that has mousedown,mouseup and mousemove events registered to it. The parent element has some child elements as well. I observe inconsistent behaviours between browser types when I hold the mouse button down, move the pointer and release the button.
ie7 - mouseup fires when over a child or parent
op9 - mouseup fires only when over the parent
ff2 - mouseup fires only over a child or parent but only if the pointer has moved since the mousedown occured
The topic of event handler management has been covered in many places in the past. One location is in the contest by PPK (http:[url]....). The winning submission by John Resig (http:[url]...._and_the_winner_1.html) has a few problems, and the commentary on the site seems to gravitate to the implementation by Dean Edwards (http://dean.edwards.name/weblog/2005/10/add-event2/) after the analysis of the Resig code.I was also able to find a few more implementations on stackoverflow from: Bill Ayakatubby (http:[url]....) and Marco Demaio [url].....
Outside of the JavaScript frameworks, what is generally done for supporting event functionality? There are numerous options each with their own benefits and drawbacks. I'm uncertain of which one to use myself. Is there an undeclared de facto?

When you click on the "details" link, a modal window pops up with the job info.This works in IE, but nowhere else. My js skills are shaky, at best, but I did figure out that event.srcElement is IE only and that there are better, modern methods of achieving this.Problem is, I don't know how to implement them in this instance.How can I rewrite this so the modal window functions correctly in IE, FF, etc?Here's the code:
Code:
function displayDetails(num,ctrl)
{
for(var i=0; i<details.length; i++)[code]...
it's possible to bind a function to an element that is fired if that element is 'moved'/repositioned via the browser.
For a more specific example what I have is a function that calculates height and width of certain elements to allow them to all fit nicely on the page without having scroll bars, and this is bound to the window onresize event. It works nicely most of the time but occasionally something will change the height of one of the elements and this effectively bumps one element right off the page.
So I'm wondering if its possible to have an event bound to an element that is fired when an elements position is moved/recalculated by the browser? Short of polling every second or so, to see if it has moved/recalculate layout.
I'm trying to augment Object.prototype with an addEvent method that will add event listeners, and will work regardless of whether the browser is IE or not.Here's what I have: So far it seems to work in non-IE browsers, but in IE8 it doesn't work. Where am I going wrong?

Is there any way to resize an iframe dynamically to the height of its content that works cross browser and works when the iframe content is on another domain than the main page (I have access to both pages, so code can be put in either) Also, it must resize when links in the iframe are clicked (ie when a new page within the iframe is loaded)
View 1 Replies View RelatedI've been looking up lots of documentation and trying to work out a
cross-platform method of capturing a keyboard event and working out
which key was pressed. From what I can find, there doesn't appear to be
any standardised keyboard event interface other than this DOM 3 Events
W3C Working Group Note [1]. However, it is only a note and doesn't
appear to be implemented in any browser. Is there another standard that
I've missed?

This is a really basic question: what does blur mean, or what does it do when used in links as described below? I've tested it on Firefox 3.6 and Opera 11 and it behaves as I hope except for one thing. During testing if I use both keyboard and mouse to navigate within the same session, the browser history for the 'other' method is wiped out; it won't go backwards beyond the most recently used method. Is this not a surprise when you know what blur really means? I want the following (assuming Javascript is enabled):
a) Keyboard users to see a focus outline on navigation links.
b) Keyboard users to see the outline still there if they use the browser Back button, and continue tabbing from that link onwards.
c) Mouse users to NOT see an outline if they use the browser Back button.

How to handle "onMouseOver" event with keyboard. With JQuery, "onMouseOver" on a "plus symbol", small banner with some text content will be shown, it has been working with "Mouse(input device)", but same effect has been expecting from "keyborad" tab ordering on to that particular "plus symbol".

how to capture Window Keyboard Event in the Child IFrame
I am having a play around with javascript and the html5 canvas to evaluate the feasibility of using it for a few personal projects.I have tried using both setInterval or setTimeout to set up a very rough framerate for an animation.The framerate is fine when coupled with a simple delta timing to smooth out the changes however when running under a large load (large images) I cannot seem to capture keyboard events very easily.
If I wiggle around the mouse a bit, it makes the keyboard more responsive but is there any way to get the window to poll the inputs rather than wait for an event to fire?This is much worse on Linux but the issue is still around on Windows.
I am trying to use the script for a PHP integrated website whereby, I am having HEADER and FOOTER for all pages. But the problem is I am already having two other Javascripts in the HEADER so, somehow I am having problem getting the script to work. When I tried to get all the three javascripts to work, the JS menu buttons refused to load properly. Below you will find how both IE and Netscape react towards the script.
Could somebody help me solve this conflict. This seems to be onLoad function handler problem but I don't know how to go about it. Or browser compatibility problem.
Something very interesting is happening and I don't know how to go about it. Below script shows the the two different reaction of both IE and Netscape.
Both IE and Netscape used to load successfull without the Random Table Backgroung Image Rotater. This problem startd when I added the Random Table BG Image Rotater that's why I am including this script also.....

After 1.5 years of writting my website I installed NS. It's JS works alot different to IE's, so it looks like I've got to write most of my site again!! [img]images/smilies/frown.gif[/img]
NS will only read 1 external JS file, which is abit of a nuisance as my site has a JS file common to site, another for the subfolders of the site, and the page's JS included with the HTML.
I'm trying to put all of common functions into one JS, but some of the functions have large amounts of text assigned to them. I'm trying to import the text using XML sheets as needed, but having a bit of a problem with the line
Code:
xmlDoc.childNodes[i].childNodes[2]
where NS will only read 1 array of childNodes. How do extract xml with NS's JS?
If my audience uses not so old browsers, do I have to use cross browser DOM? If they have IE 5 or later and Netscape 6 or Mozilla 1.0 or later and any version of Opera that is not older than 6 months?

In some pages of my website I use a code like the following:
for (var n = 0; n < getTagsArray("SPAN").length; n++){
//SPAN is just an example. I also use other tags
tag = getTagsArray("SPAN")[n];
//make something with tag...
}
function getTagsArray(Tag){
if(document.all){ //Internet Explorer
return document.all.tags(Tag);
}
else if (document.layers){ //Netscape
eval("return document.tags." + Tag);
}}
I want to put all browser-specific code inside the getTagsArray
function. So far, I've programmed only for Internet Explorer (my
browser), but now I want to make my website visible to all browsers.
I'm not sure about the getTagsArray function. Is it right or is there
a better way to do the same thing? And how can I extend that function
to make it work in other browsers?
Finally, where can I find some information about cross-browser
programming? I have the javascript reference for Internet Explorer and
Netscape, but I know nothing about other browsers.
a lot of the code I have trouble with is events-based, although there are some DOM-navigation problems that I've noticed in IE.
before I launch into a probably fruitless attempt to write an API that corrects IE's DOM-mangling, I'm wondering if someone else may have already invented that particular wheel.
ideally, this would be a script which I simply link to in the head, and then write valid DOM code which automagically works.
onclick="getElementById(Ǝ').style.display='inline'" title="Show Comments">show</a> / <a href="#" onclick="getElementById(Ǝ').style.display='none'" title="Hide Comments">hide</a>
This is a snippet of code from my HTML, and it has been giving me a lot of trouble. It works in IE6 and FireFox, but not in Opera and I can't test other browsers.
What I'm looking to do is make this as cross-browser friendly as possible, which I'm guessing might be able to be done by the way of javascript functions.
The only problem is I don't know any javascript, this is all I know and a quick solution is all I'm looking for.
So maybe, firstly it would be best to ask if it is even possible to achieve this show/hide effect on all browsers, and if not, what options I have?
I need a free cross browser dhtml tab control.
