Universal Browser Compatibility - Mobile Device Connectivity This Is Making Things Even Harder
Feb 7, 2011
We run a click and sales tracking solution for our advertisers and as such we are having a few issues with browser compatability for certian sites that are ont eh Magento platform. Essentially we are just trying to create an image call in javascript that uses a few pre-populated variables from the checkout process.
So teh issue we are having doesn't seem to be broser specific. We are trying to simplify the javascript call to ensure we have the highest possible chance of compatiablity. Obviously now with so many differnt browsers and also mobile devide connectivity this is making things even harder. We know that our javascript calls are failing as we've been monitoring our IIS logs and can see the image calls are being made with blank variables. There are 3 different elements to our checkout calls that maybe you guys have experience of with possible issues or fixes:
1. unescape function
2. onload event function for images
3. creating images dynamically
these are very basic elements of the javascript core but aout 5-10% of our calls are failing with blank variables being passed into the image call. So the questions is what elements of our call will be the possibel sources of failure?

I work for masterclock. We sell network synced clocks and timing systems. One of our products is a "bell ringer." We currently control this ringer through a C++ program another one of our employees made. However, it only works on Windows systems, looks like crap, and is as confusing beyond all get-out. I have been given the task of rewriting this program in a pretty, easy, and universal format. i.e. a browser. Now to further explain the bell system program.
1. The program searches the local network for the bell system hardware.
2. User chooses appropriate hardware (if more than one bell system exists) to connect to and enters the password.
3. User edits tables stored in a local MS Access database via the bell system program UI.
4. User sends data to the bell system hardware it is connected to.
I've been racking my brain and the internet for about 6 hours trying to see what is possible. Because this all needs to be done locally I can't use any sort of server-side language like php or asp. It seems silly to make a client install a virtual server to connect to a file that is on their own computer. I'm assuming that I am pretty much limited me to javascript. I found this site but that only works with internet explorer which is almost as restricting as the program we have now.
I considered flash for a little while until I found out a swf can't connect to a database w/o using php or asp. We aren't limited to the MS Access database but it would be less work for me if we could stick with it. It may not even be possible but it seems like it should work. some way. We also considered an internal site on the bell ringer hardware itself, like routers nowadays. I think that would be an equally if not more difficult process though and I'm limited to about 500kb on its flash memory.

I was really hoping that someone could help me sort out two minor problems which I'm experiencing with by JavaScript and two browsers. (FireFox and Safari)
1. Safari doesn't support style="background:#CCCCCC;"
I use the following JS code to change the background color of my select boxes.
HTML Code:
var backcolor = "#CCCCCC";
document.getElementById('operatings').style.background = backcolor;
Unfortunately Safari doesn't support this. I could use the following :
HTML Code:
var backcolor = "#CCCCCC";
document.getElementById('operatings').style.background-color = backcolor;
...but it doesn't work. Probably because the JS reads the dash ( - ) as a syntax error. What alternative is there to this?
2. FireFox doesn't support 'value="";'
I use the following code to reset the selection of a <select> drop down :
HTML Code:
document.getElementById('operatings').value = "";
...but FireFox doesn't seem to support this.
What alterative is there to unselecting the selected the option in a <select> dropdown? I know about the reset button, but unfortunately I cannot use this.

Can anyone shed some light on the JavaScript support on many of the
most common mobile browsers (the newest versions of Blazer, Blackberry
and Pocket IE)? Specifically, I am trying to render some content using
innerHTML when the page loads without success. document.write is
supported but does not meet my needs.

I have the following funciton that centers my website content for any size window and will center it in real time as the window is expanded or shrunk. It is activated by a
onresize="CenterIt();"
in the body tag.
Works fine for IE. How do I make it compatible with netscape and most browsers? Better yet, is there a good single source that explains how to write javascript to be compatible with all browsers? 766 and 435 are the width and height of my table that surrounds the website data defined so:
<TABLE id="Main" style="position:absolute; z-index:0; top:0; left:0;">
function CenterIt()
{
newOffsetWidth = 0;
newOffsetHeight = 0;
if (document.getElementById)
{
winW = document.body.offsetWidth;
winH = document.body.offsetHeight;
}
else if (document.all)
{
/*
What goes here????
*/
}
else if (document.layers)
{
/*
What goes here????
*/
}
if (winW > 766)
newOffsetWidth = ((winW - 766) / 2) - 10;
if (winH > 435)
newOffsetHeight = ((winH - 435) / 2);
if (document.getElementById)
{
document.getElementById('Main').style.left = newOffsetWidth;
document.getElementById('Main').style.top = newOffsetHeight;
}
else if (document.all)
{
/*
What goes here????
*/
}
else if (document.layers)
{
/*
What goes here????
*/
}
}
CenterIt();

Is JQuery live() supported in mobile app browsers? I am having a difficult time getting an application to work. I've posted some code to illustrate/test the problem below. Three lists, #1 using bind(), #2 using live(), and #3 using live() whilst allowing to add list elements. Clicking the list item should just bring you to a second page that displays your selection (it updates whatever was there before, original text is 'original' text). Works great on my PC in all browsers except IE, and on Android/FireFox, but not with IPhone/Safari and Andrpid/WebKit: ot only is the event not triggered on dynamically added list elements, it's not triggered on the 'static' elements in lists #2 and #3. The app was written using JQTouch; wondering if that disrupts somehow JQuery functions.

Is there a resource on the internet to tell me which javascript can
work with which browser.
For instance, can I use style.color with all browsers - that kind of

I have looked around and not been able to find a definitive answer to this. Prototype does not work in IE 7 or lower. All other browsers work just fine. Even something as simple as toggle(); will not work in older versions of IE. I don't get any errors or anything like that. It doesn't really seem like a compatibility issue as much as it does that those browsers could be parsing the code differently?

Im trying to design something that would be intuitive for the user to
represent rotating something. Think along the lines of rotating an
image a specific amount of degrees. The obvious choice is to have the
user input CW or CCW and the number of degrees but i would rather
present something graphically and let them manipulate that, then in JS
determine the rotation.
The only thing i have been able to come up with right now is something
along the lines of the iPod click wheel with a dot at the top. As it is
clicked and dragged it spins, but the problem is i dont know if this is
possible in just JS / HTML, i don't want to use flash.

I have managed to create a very basic form validation script that I can retrospectively add into current forms with the least effort.
As far as the validation goes I am sure that the script is not pretty, but it does work. However, I have failed to manage to get it to return the focus to the first field that errors.
My abortive attempts are not included in the attached script because I have tried and failed with many different attempts that I have confused myself. I would appreciate any advice that could point me in the right direction to place the focus in the first error field found. Code:

using js to force a specific anchor call to jump after the page completely loads. The reason I am doing this is because the page I am linking to with anchors takes a long time to load and a standard browser anchor link sometimes does not work 100%. With that said, I would now like to make the script I wrote universal to get ANY anchor param in the url and jump to that spot on the page. Right now it's coded to just look for "#anchor". I want to re-code it so it will look for "#" + "anyAnchorName".

I'm making an HTML5 web app which can use on both android and iOS devices. Here I want to use a scrollview with y direction paging and "data-scroll = yp" work for me. But here I'm experiencing an issue with device orientation change.So inportrait mode when we seeing 2nd page, scrollview offset is -768 and it is ok. But here if we rotate the device to landscape mode, then to see the complete page scrollview offset should be -1024. But still it is remaining in -768. So we have to give some touch movement to jump it to correct position.Actually this is a huge bug for scrollview and I tried a lot to fixed this. I bind a method with orientation change in scrollview widget and that method can not access other properties in the widget.

I have a site that can be downloaded and run on a closed network (not needing an active Internet connection). I'd like a page that displays live data to a user with Internet connectivity (I can do this) but display "canned" data when the user is without an internet connection...and this difference in page display is transparent to the user. I know this can be done with php but the user without Internet connectivity will likely not be able to run php locally so the page must be an .htm file. I there a javascript somewhere that does this?
