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?
how to clear browsers' cache with javascript? .. so users will unable to go to previous page after they logged out.. I tried to add <meta http-equiv="Pragma" content="no-cache"> on head section of my page1.jsp .. but it does not work
just came across this in a book for browser javascript on/off detection:
Code: <noscript> <img src="monitor.php?scriptoff=true" /> </noscript> just wondering if browsers when js is off will ever access any <script type="text/javascript" src="file.js"></script>
files? i mean wouldn't it be better not to bother with the noscript thing and just be aware of if file.js is accessed? or do some browsers access the file.js even when js is off?
I have designed a mail service in java.In my compose page,i want to attach some excel files of text files and to send it.After sending i want to store it my database.Then how can i download or open that file after opening that recipient mail inbox.
I have the following JavaScript (see below). The script requests an XML file from the server and displays it on the page.The script works fine when the requested XML file is stored on the same server as the script.The problem is when I try requesting an XML file from an external server such as the National Weather Service. I get an error. If I take the XML file from the National Weather Service and save it to my server it works. Why can't I use my script to request XML files stored on external servers?
Javascript Code
Code:
window.onload = initAll; var xhr = false; function initAll() { document.getElementById("makeTextRequest").onclick = getNewFile;
In my quest to implement ajax for the first time i've hit a brick wall. i've been searching for hours for a solution but with no success. Here is the problem.
[Code]...
why is it not working? my PHP code is outputting the contents of the xml document.
I want to write a javascript to list of all files in a folder including files in the subfolders. This is for the scorm purpose to list all the files. some examples are listing files but not listing the files inside the subdirectories. I want the file's full path like C:Documentsjavascriptwilson.js like this.
I have four folders and each folder has one images, let say ( images-one.jpg, images-two.jpg, images-three.jpg, images-four.jpg). now,in index.php page there are four buttons, each buttons for each images. if i clicked button numer two for images-two.jpg, and then it will show that images name from that folder in index.php page. and then if i reload same index.php page or refreshed same page, i want to show SAME images that I clicked before which is images-two.jpg. how can i write that code to show images from four files, each files are in each folder.
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?
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 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.
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.
When 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?
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> </head>
<body bgcolor="#ffffff" text="#000066"> I'm working with some large images that are in markup but being processed into queued animations. If image is already loaded but I call $load will it pull image from browser cache? I want to use the success to do some size processing
I need to cache some javascript variable values across the page. Consider page 1 has a javascript variable which holds some value and If the user take page 2 and clicks the browser back button the javascript variable value on page 1 will be lost. How can I cache the javascript variable value on page 1.
I 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)
If 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?
