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)

AJAX :: Clear Browser Cache With Script?

Jul 26, 2011

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?

Clear Cache When A User Enters Something In Address Bar And Press Enter Key?

Sep 10, 2007

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?

Spry Form Validation Breaking Back Button Cache?

Apr 20, 2009

I use Spry for my form validation and have recently ran into a small issue. Form fields validated using Spry lose their value when I hit the back button. Fields without validation retain their values.

The form is using the POST method. With javascript, is it necessary to send the form variables back to the original form page?

Implement Clear Function Using Reset Button

Jul 23, 2005

i need to implement a clear button to clear all the fields in the
form, but i am thinking i can just use reset button.

<input type="reset" name="reset" value="CLEAR">

The first thought is that if there is default value reset and clear
will become different. My understanding is that reset means to restore the original page
before any edits by the user.

It seems like I can use reset button to implement clear javascript button.

Generic ClearForm Function When Click CLEAR Button

Jul 23, 2005

I want to write a generic clearForm function to clear the form when
the user click CLEAR button.

Here's my attempts, because I want to take care all html controls. I
think I need to test if the control is submit button, regular button. But I don't know
what I should do on drop down box?

function clearForm()
{var i=0;
for (i=0; i<InputForm.elements.length-1; i++)
{var obj = InputForm.elements[i];
document.write(obj.type); //runtime error: object doesn't support
this property or method
if (obj.type != "submit" && obj.type != "button")
obj.value = "";
}}

Confirm Dialog Button Not Firing To Clear Data

Oct 5, 2011

I used this button to clear the database. It works perfectly:
HTML Code:
<input class="clearButton" type="button" value="Erase Data Now" onclick="clearData()">
However, it would be better to put it in a confirm dialog to prevent accidental use. So I used this line to open a dialog box:
HTML Code:
<input class="clearButton" type="button" value="Clear Data" onclick="confirmation()">


I used this script for the dialog box:
Code:
<script type="text/javascript">
// Confirm Dialog box from [URL]
function confirmation() {
var answer = confirm("Are you sure you want to erase ALL data you entered into the fields on this page? Action cannot be undone.")
if (answer){
onclick="clearData()";
}else{
onclick="close()";
}}
</script>

However, the
Code:
onclick="clearData()";
is not firing, but the
Code:
onclick="close()";
works fine, dismissing the dialog box. How do I incorporate the clearData so it works?

Ajax ::Submit Inputs Values Using Normal Button / How To Keep And Clear Values

Apr 15, 2010

In part of my form, I have 3 inputs (one textarea and two text inputs),I am validating their value format using AJAX (each input triggers error message on its label in case format is wrong). Also I have one button, "NOT submit button" (type = button).Now, when clicking on the button it must enter the value of those three inputs in my database in case they are true then all inputs values must be cleared. In case AJAX validation is wrong and in case the user clicked on that button, the value of fields must kept as it is.

Actually I can not use submit button because I have it for the whole form and what I am taking about is a part of the form and it's not possible to make nested forms as I know it violates html rules. It's easy to make it if I am taking about submitting button as I can view session values on fields after submission in case ajax returns error.I can clear inputs from Javascript, but it will be cleared on both cases if AJAX validation true or wrong. Each input field has AJAX Error message that will be triggered when the input format is wrong.

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.

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.

JQuery :: Cannot Find Way To Cache Content
