Cache/save The Styles Of An Element?

Jul 8, 2010

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)

Changing Element Styles In Real Time

Feb 6, 2003

I'm using sliders to change text colour dynamically; at the moment, I'm doing it by iterating through the getElementsByTagName collection; like

paraAry = document.getElementsByTagName("p");
paraLen=paraAry.length;
for(j=0;j<paraLen;j++){
paraAry[j].style.color = "rgb("+bodyColor[0]+","+bodyColor[1]+","+bodyColor[2]+")";
paraAry[j].style.borderColor = "rgb("+textColor[0]+","+textColor[1]+","+textColor[2]+")";
paraAry[j].style.backgroundColor = "rgb("+textColor[0]+","+textColor[1]+","+textColor[2]+")";
}

But blatantly it's well inefficient; is there a better way to achieve this - like just a single property I can change to make all elements of a given name change.

HTML 5 Canvas Element Animation Save

May 18, 2010

My application is based on client-server architecture. It is a E-Learning Application. I am using ruby on rails server, javascript,canvas,SVG element. I have an idea of an interface to allow the teacher to build any type of animation for students using Cake javascript API. I wanted to save the animation build using the canvas element on the rails server either in database or as a file. Later I have to use that animation to be played to students. Any way to do it on any language except proprietary languages like flash but from that language communication can be done with rails server.

Do Browser's Cache .JS Files?

Jul 23, 2005

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?

Loading Js File Into Cache

Sep 22, 2006

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.

Clear The Cache With A Button?

Sep 21, 2010

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)

Function Persists In Cache

Jul 12, 2011

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?

[Internet Explorer] Cache Pbl With A Popup

Jul 23, 2005

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 ?

XMLHttpRequest In FireFox And Browser Cache

Jul 23, 2005

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.

Cache A DHTML Updated Webpage?

Sep 16, 2010

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?

JQuery :: Cache The Sizzle Parsed Strings?

Apr 21, 2010

The scenario would be something like checking if an element fulfills some complex conditions, something like if(myElement.is('div.someClass[someAttribute], td.someOtherClass[someAttribute]')) ... . Is there a way to parse that string only once, maybe create some sort of "compiled" version of the check, cache it, then give it to is ? Or does jQuery cache the string after parsing it once so I don't have to do anything?

Resolved IE CSS Cache And External File Updating

Jun 11, 2009

Working on a little window to do some very simple quick edits to an external CSS file. Whole thing is working off of Ajax URI strings and GET methods.Once a edit to the loaded CSS source has been performed I write back out the the external css file via Ajax GET method and PHP fopen. Then while the file writing completes, I return back its newly saved contents to the head of my document.In my documents head I have a div block with a unique id that gets traversed to via DOM and our newly edited external css files contents gets dumped too.Upon dumping the contents of the external css file to this div block I wrap style tags around the incoming contents like so.

Ok great so that's the break down of my whole editing and updating preview of an external css file, now my problem. Works fine in FireFox and not so well in IE.I suspect its because IE caches CSS harder than the FF Gecko Engine. Thus leaving me here to ask if anyone knows of a work around for my approach or a more elegant method that I might want to investigate?
