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]...
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'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?
Code:
(function(){

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)

IE has no problem with this, but Firefox throws an exception - "Illegal operation on WrappedNative prototype object". Is it within its rights to do so?
I am trying to assign a variable to a jquery object that is found using the children() and eq() methods. This is a simplified version of the html structure.[code]Here is the jquery code. All I want to do is assign an object to the variable and be able to manipulate the object through the variable. [code]Again this is a simplified version of my code but the structure is similar.
View 2 Replies View RelatedHere's my object constuctor:
function suggest_object(result_id)
{
this.in_result_div = false;
this.search_element = document.getElementById(result_id);
}
And the execution code:
var suggest = new suggest_object(result_id);
document.getElementById(result_id).onmouseover = function(){suggest.in_result_div = true;}
It works as is, but i'd really like to be able to set the onmouseover inside of the object. Something like
function suggest_object(result_id)
{
this.in_result_div = false;
[Code]....
So how can I get the 'this' inside the onmouseover function to refer to the object?
I have a simple filmstrip that uses getJSON to return data. The data is an array containing two arrays. The first, is the base path to photos. The second is a list of the photo file names. I am trying to loop through the array of photos and set them in divs. Then I need to attach an event to popup a larger view of the image placed in a dynamically generated div containing the image and initially hidden.
So what I am trying to accomplish is:
1. get JSON data from server.
2. get base image path from json data array
3. get list of images from json data array
4. Loop through list of images, prepend base path and assign to hard coded div.
5. create a dynamically generated div with larger version of same image.
6. Attach hover action to cause a mouse-over action on the hard coded div to popup the dynamically generated div containing the larger version of the image.
My issue is that once my code runs, no matter what image in the filmstrip I mouse over I always get a popup with the last image in it. Here is my code:
<script language="javascript">
$(document).ready(
function(){
$.getJSON("<?php echo site_url('filmstrip/index');?>",
function(data){
var dir = data['dir'];
var imgs = data['imgs'];
var i =0; .....
I want to find x, y location of a layer or an image, or any other item
on a webpage.
1. It could be relatively or absolutely positioned.
2. It does not matter what browser the user is using.
what's the correct javascript code?
example: find x, y location of the image "someImage"
<html>
<body>
......... some html here....
<img src="someImage.gif" id="someImage" />
......... some html here....
<body>
</html>
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.

would like to know which is the best WYSIWYG editor you are using for every of your application? I do not actually have any since i'm not in need but I may consider adding one to one of my upcoming project.
View 1 Replies View RelatedI am building a webpage that loads information from an XML file. I am using XMLHTTPrequests.
On page load a function populateH(); is called which reads the XML file and populates the HTML(Home) page accordingly. The function uses getData() functions to read and write from the XML file.
The page works properly in FireFox, but the populateH() function doesn't seem to work with other browsers. I have tested my getData() functions in other browsers and it seems to work fine.
(example available at: [url]
My get data function is written as follows:
Code:
And my populateH() function is written as follows:
Code:
I use the XMLHttpRequestObject in the populateH() function to set the nodes to retrieve, and the getData() functions are called in the place functions (placeNews(), placeFriends(), placeLinks()) to write to the HTML document.
I have a website[URL]... that has a car search box functionality which uses an external javascript file to populate the makes and models within the dropdown boxes.
A few weeks ago I realised that it didn't work in safari (initilly I had the populate onload code attached to the submit image), I then moved the code into a inline script tag and it worked but now i've realised it doesn't work in Firefox... I am now thinking of adding a script to determine the browser and dynamically work on adding the populate code depending on the browser but thought it would be a good idea to post on here in case there is an overall much better solution. If you visit the site you will see a working example of the issue.
I'm trying to find a javascript/DOM navigation tree to use in a
web-based content management system, to allow navigation of > 10,000
folders/files.
The javascript (non-DOM) tree we currently use is running too slowly
as it cannot dynamically load in nodes when users select a node to
expand. This is critical for us. The top level of the tree hirarchy
only has 20 or so nodes, but each node might contain up to 1,000
nodes.
So what we need is for the tree to process and display the first tier
(20 nodes) and then only process sub-nodes if the expand icon is
clicked.
Does anyone know whether such a tree exists?
It needs to be compatible with all modern browsers (IE 5+, Netscape
6+, Opera 7+, Konqueror 2+, Safari etc). I've looked at several
different examples, but none of them (AFAIK) appear to be fully
compatible with the above list of browsers.
I am brand-new to javascript, but after reading some tutorials online I
was able to make a dynamic HTML photo gallery in javascript. It works
fine in all browsers except IE6 (big surprise). I've been looking
around online for solutions, but the fixes I have seen don't seem to
work. I assume I am misunderstanding something... I was using
element.setAttribute but have changed my code to avoid that. Here is an
example. IE6 displays the link text but doesn't do anything else--exact
same result I had by using element.setAttribute('name', 'value').
