View 11 RepliesI have a 3 drop down menus used in a form. Depending on what the selection is of the 1st drop down menu, the contents of the the 2nd and 3rd drop down menu can change.
I have all the contents of the drops down menus stored in an array in an external .js file. That way I can manage the content better and upload new .js files whenever I need to.
Since the contents of the .js file can change frequently, my question is how can I ensure that people using the form are always accessing the most up to date .js file without having them to refresh the page?
I am very new to this and have just written some code to randomly generate an image on my web page. Each time I test it, a bar at the top of the page comes up saying:
"To help protect your security, Internet Explorer has restricted this file from showing active content that could access your computer. Click here for options..."
How do I stop this coming up on other peoples computers, because if they don't click OK, they can't see my images? Is it my script that is causing an issue, or is there a simple fix for this?
Many thanks in advance for your help, and please remeber I am very new to all this, so try to explain in simple terms.
A Java applet has two methods stop() and destroy() that get called when the user moves to a different page. Does javascript have anything similar?

Everything seemed to work great until I noticed the menu always stays visible as you scroll down the page.
How can I make this menu stay put exactly in the layer (yellow bar) and not scrolldown? Code:
Basically, I have a page that I load with 10 input fields. If users
have JS enabled I want to hide 5 of these fields so as to reduce
clutter. If the user needs these extra fields an "Add" button can be
used to display the hidden fields one by one.
Once the fields a filled in the user submits them for validation and
if there are any error They can "Go back" to make some changes. The
whole process works great in FF & Opera but IE lets me down because if
you use the Browser "Back" button the Javavscript gets executed even
though it should be loaded out of cache.
I m trying to make a person stay on same page on cancel, but the confirm takes the user to the next page like they press ok. how can i stop it? code...

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?
What's the simplest way to fetch a js file from the current website, then
cache it?
I'm using dojo, which has a large js file when using the built version.
As a mercy for dialup users, I want to serve up a tiny 'loader' html page
(containing an animated 'loading...' gif) which, when loaded:
1. retrieves the big js file, and plants it in the cache
2. when the js file is retrieved, then sets document.location to
the url of the real website page which uses this js file, and
thus redirects to that page.

The cache in Tomcat really gives me hard time, it seems no way to handle the
cache control. I am using Tomcat 3.2 on NT 4, I don't know the newer
version would solve this problem.
I am sorry if this has been asked already. I searched but could not find a suitable answer.I am making a simple RSS reader (using jquery mobile) and I need to be able to cache the resulted feed.To understand better let me explain alittle. I have a page where the users selects the desired category. After that he is taken to a different page where the titles of news are. here the feed is read for the first time. When the user click on a title he is taken to another page where I want to display the content of the selected news article.Sincethe feed was already retrieved on the previous page, I want to be able to cache it so that it won't be retrieved again.Any idea how I best do this?

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 have removed the definition of a certain function from a third party plugin, and also removed all found references to this function throughout the code. The purpose of the function is to display an emoticon. However, it seems that if I refresh the page a few times, the emoticon appears sometimes, but not always! It appears this function is cached somewhere, but I have deleted my browser's cache already. Also, I can't figure out why the emoticon only appears sometimes, as if randomly. If the function is indeed cached somewhere, and I couldn't find all of its references, then the emoticon should appear always?

I have a problem, and maybe someone knows the solution.
Context :
- Browser : IE 6.0
- Application server : Livewire Pro
- Client OS : Windows 98 SE
- Server OS : NT4
- I have a frameset, including several pages, but only one will be
used for the example.
--------
| a |
--------
| b |
--------
- a form on the main page (a.html i.e.)
- a data is manually typed, then I submit the form => the action will
redirect to a new page (c.html)
- on this new page, I do a history.go(-1), so I'm back on the a.html
page, and the data is still there (it's ok)
- cache parameters : "check on every page visited"
Problem :
- From the main page, if a popup gives the data to the form, so after
the submit and the history.go(-1), the form contains NO data !!!
So, the data is lost when the data input is not made by hand.
I have no troubles with Netscape/Mozilla, but only with IE.
Maybe someone would have an idea ?
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 a DOM manipulated page - manipulated with jQuery.The user follows a link on this page - but when he uses the back button all the previous JSON data is lost and the original (unmanipulated) static page is shown.This is putting a *STOP* on our project.I cannot find a way to cache the content - have tried headers and mod_cache in apache... it still simply shows the original page.To make things worse different browsers give different results.
View 1 Replies View RelatedWhen using the function to switch images as shown below, I want to check if the image is already in the cache to prevent showing the css .loading class. The .complete() object just made a lot of trouble but I couldn't use it probably. The switchImage Function is fired when pressing a thumbnail or a prev/next button.Is their any solution to check whether the image/url I want to load is already in the cache?

View 3 Replies View RelatedI want to cache the styles of an element, but saving the ".style" object won't work because any changes to that are also applied to my saved variable. What's the best way to cache the styles of an element? (Needs to work across major browsers)
View 2 Replies View RelatedIf you use javascript/dhtml to, say, add a text field to a web page. If you then navigate away from this page and back again using the back button the added text field is lost and the web page is back to how it was prior to any dhtml changes.
I assume this is because the browser is using the cached version and not the changed dhtml version.
How can I force the changed web page to be cached so that when returning to the page the dhtml version is the page I see with the added text field?
