The following code is working fine in firefox n not working in IE8... I get the Object Expected Error when the code hits the if(GBrowserIsCompatible())..... line in the javascript code. Clear cache and browser history does not work. Does anyone have a resolution for this?

OK, so I have an AJAX app and am using browser caching to reduce the number of server calls. However, I wanted to be able to clear the whole cache for the browser if the version of my AJAX app has changed.
My plan is to have the version number stored in a cookie on a user's machine. The first thing my app then does upon load is check the version number of the javascript to the version number of the cookie and if they are not the same clear the cache.
Is this possible?
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?
View 9 Replies View RelatedIs there a way in Javascript, or perhaps in HTML, to force a browser to
re-render an image on an HTML page after a round-trip between the client
and the server ?
In my particular case, the image is changing on the server although the
URL for it remains the same, but the browser is still displaying the old
image from its cache rather than the new image from its URL location.
Using IE 5.5(sp2) no other!
I have several .js files that are included in various jsp pages.
I've read somewhere(can't remember where?) that the browser caches .js
files.
If this is the case is it better to include all of them in the 1st page of
my app regardless if they're used in this page & take a performance hit
once? - or am I missing something?
Does anyone know of good links about cross-browser compatibility (html
attributes/css2/javascript)?
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.
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();
Does anybody know how to make FireFox to cache data that comes via
XMLHttpRequest? Here is the issue I deal with:
- On the web server (apache2) I have a static xml file test.xml
- When I download test.xml using XMLHttpRequest, FireFox always gets
complete test.xml from the server, thus not using the browser cache
(apache sends 200 OK back to FireFox).
- If I look into the HTTP request and the HTTP response, I can see
that FireFox seems to always set the following request headers:
Pragma: no-cache
Cache-Control: no-cache
- Apache always sets Last-Modified and ETag headers in a response.
I tried the same JavaScript code with IE, and IE definitely relies on
its cache: I can see in Apache logs responses with 304 Not Modified
code for IE, also HTTP requests from IE have If-Modified-Since and
If-None-Match headers. I didn't find any difference in responses Apache
provides for FireFox and IE.
I have an Apache PHP enabled webserver and want to know from where users are coming from.
Understand I want the last surfer's browser visited url. I imagine I can do this with some kind of interraction between 2 scripts : one client side, one server side. The client one send the URL and the server one write it in the right log file....
I search for a way in javascript to prevent browser from caching my
HTML page in its "history" and "temporary files" if there is any .
Is it possible to force an entry into the browsers history without actually changing pages? I want to change the history based on a tabbed interface so that when linking away from one of the tabs a back button will return me to the correct tab or even the browser back button for that matter.

My clients have a, "Family Violence" Prevention website and they have asked me to create them an "Exit" button so that the users could escape the page quickly if they heard their abusive partners.
I added the "javascript:document.location.replace("http://www.google.com")" to the button to disable the back button, but it only works on the last page viewed.. if they viewed more than one page on the website it takes them back to the page before the last page viewed.Is there a way to remove all pages from a domain name? or remove all browser history before that?
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
thing.
The following code works for Firefox but not on Chrome. Does anybody know what it doesn't work on Chrome. Is there a document on the browser compatibility info on each JQuery command.

Hint me about an easy and clear way to cache ajax response into client browser WITHOUT using the JQuery? I am unable to find that on google.
I have a page that is loaded using AJAX and it takes long time to load every time (approximately 28 seconds), so I need to cache it to reduce the time. I tried the stored procedure for database, but it did not give me good result, so I want to try the caching.
I am using javascript to load and parse a big xml file (around 1 mb) save some values to an array and draw a picture using google Flot. Unfortunately, this causes the browser to crash! Is there a way to clear the memory of the browser?
View 2 Replies View RelatedWe 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 have a client that wants a site for people who are potentailly being abused, often by partners they live with.
He is under the impression that it is possible for there to be a "Button" that deletes the cache when the user presses it rather than going through the procedure of clearing the cache. I can see why this would be a goog thing to have, and wondered of js (or perhaps php might be the way to go)

I am working on a online video portal build on flash/actionScript.
If I enter a url of a video when another video is playing, it doesn't playing the new video but it keeps on playing the old video. The reason I think is as it is a RIA, it doesn't refreshes the page and looks for a flash object and its already cached so it doesn't makes any http request in order to play the new video.
So I am planning to claer the cache.
how to clear the cache when a user enters something in address bar and press enter key?
