Lightweight generic busy indicator
Hi!
I am trying to maneuvre a lightweight gmail-style busy indicator to
stay in place whenever I click an operative button.
The script seems to work fine with regular submit buttons, but I have
not found a proper way to reset the indicator in context with ajax
buttons and links.
Is there an event I could bind this to, or do I have to push some
javascript from the server side / tweak the wicket-ajax.js? It would
be pretty nice if I could just overload/hook-to something on
javascript level.
Here is my code:
<style type="text/css">
#busysign {
display: none;
float: right;
background: red;
margin-top: 5px;
margin-right: 5px;
z-index: 1000;
width: 200;
font-weight: bold;
text-align: center;
font-size: 1.3em;
}
</style>
<script type="text/javascript">
window.onload = setupFunc;
function setupFunc() {
document.getElementsByTagName('body')[0].onclick = clickFunc;
}
function clickFunc(eventData) {
var clickedElement = (window.event) ? event.srcElement : eventData.target;
if (clickedElement.tagName == 'BUTTON'
|| (clickedElement.tagName == 'INPUT' && (clickedElement.type ==
'button' || clickedElement.type == 'submit'))) {
document.getElementById('busysign').style.display ='inline';
}
}
</script>
I would equally well appreciate if you had some alternative generic
lightweight solution :)

I must say that in my experience, 'worksforme'. Whenever I have had
problems with the indicator it has been because the javascript has
crashed. You can debug the javascript by putting alert('Hello'); in
some places you want to debug. This will quickly show you which parts
of the javascript really get executed and which parts do not.

Hello, I put this code into my application and its very non-intrusive and
easy to use. I found a slight problem with it though that I am able to
replicate but not able to fix.
It happens when a page using a form is loaded through the browsers url
directly, instead of through a link in the application. So for instance if a
user bookmarks a form, or opens a browser and types in the form url, when
the form is submitted the indicator displays as it should, but it does not
ever hide when the request is finished.
In my instance I am submitting the form through ajax with validation errors,
and the validation messages come back as they should but the indicator
doesn't hide. I've tried putting the js outside of the html head tag, but it
didn't seem to help. Interestingly enough, if I type the url and go to the
form, and click refresh once, it works fine again. Almost like for some
reason it can't be used on the page that creates the users session. Any
ideas about this?

Hi!
I put it into the Reference Library -> Ajax as "Generic Busy Indicator
(for both Ajax and non-Ajax submits)"

I'd have thought that either under the "AJAX" or the "View layer"
topics in the Reference Library[1] page. If so, go to the 'topic'
page for the one you choose ([2] or [3]) and "Add page" your own page
which should then automatically appear in the lists.
If you've already created a page, it's not a problem as it's possible
to move it around. As for which one to use, which would you look for
it under?

I had a look at the wicket wiki:
http://cwiki.apache.org/WICKET/#Index-FrameworkDocumentation
Would you consider it it the right place or would you suggest a more
suitable location (and would that require any special publishing
rights)?

Yes because calling it with brackets, does actually call the
showBusysign method and gives the result to registerPreCallHandler..
Doing with out brackets passes the method as wanted.

Ok. So I finally figured out my javascript syntax mistake. Do not use
Wicket.Ajax.registerPreCallHandler(showBusysign()) but instead without
the brackets with the function:
Wicket.Ajax.registerPreCallHandler(showBusysign);
This snipplet is now complete and can be used with any application:
<script type="text/javascript">
/* Your web page must contain this:
* <div id="busysign">Loading ...</div>
*/
window.onload = setupFunc;
function setupFunc() {
document.getElementsByTagName('body')[0].onclick = clickFunc;
hideBusysign();
Wicket.Ajax.registerPreCallHandler(showBusysign);
Wicket.Ajax.registerPostCallHandler(hideBusysign);
Wicket.Ajax.registerFailureHandler(hideBusysign);
}
function hideBusysign() {
document.getElementById('busysign').style.display ='none';
}
function showBusysign() {
document.getElementById('busysign').style.display ='inline';
}
function clickFunc(eventData) {
var clickedElement = (window.event) ? event.srcElement : eventData.target;
if (clickedElement.tagName == 'BUTTON' || clickedElement.tagName
== 'A' || clickedElement.parentNode.tagName == 'A'
|| (clickedElement.tagName == 'INPUT' && (clickedElement.type ==
'BUTTON' || clickedElement.type == 'SUBMIT'))) {
showBusysign();
}
}
</script>
Do you think I should add it to the WIKI?

Re: Lightweight generic busy indicator
Posted by Martin Makundi <ma...@koodaripalvelut.com>.
Hi!
In my understanding it should (IMHO) be possible to hook all ajax
calls without doing anything on the server side. I think your "add
onClick to an AjaxButton" issue involves attaching specific javascript
(from the server side) to a specific button. That's not what I need,
is it? I would have to roll out a new global ajax button having the
amendments....no. That's an overkill (is it the only solution???).
I just want the indicator to become visible whenever any ajax request
starts and the indicator to be again hidden whenever the ajax request
stops/terminates. I do not want to affect the ajax behavior itself, I
just want to add one intermediate function call.
There should be a generic clicent-side (browser) hook or way to tweak
this. I tried chaning the body onload setupfunc to the following,
which had the result that all ajaxfallbackbuttons fell back into
normal mode:
function setupFunc() {
document.getElementsByTagName('body')[0].onclick = clickFunc;
hideBusysign();
Wicket.Ajax.registerPreCallHandler(showBusysign());
Wicket.Ajax.registerPostCallHandler(hideBusysign());
Wicket.Ajax.registerFailureHandler(hideBusysign());
}
So I just want to add the show/hideBusysign in addition to the
existing functionality. Do I have to fork wicket-ajax.js or is it
possible to achieve it using scripting within the markup file?

check my posts on "add onClick to an AjaxButton" in the users list (I

It seems that you have a similar problem.

Re: Lightweight generic busy indicator

Hi!
Did I misunderstand something? I am not a javascript-wizard ;) I could
make it work perfectly with non-ajax buttons and links but it does not
seem to react to wicket ajax buttons.
Here is the script code, pls take a look if there is a blatant bug (I
assumed I do not need to make any modifications onto the server side):
<script type="text/javascript">
/*
* <div id="busysign">Loading ...</div>
*/
window.onload = setupFunc;
Wicket.Ajax.registerPreCallHandler(showBusysign());
Wicket.Ajax.registerPostCallHandler(hideBusysign());
Wicket.Ajax.registerFailureHandler(hideBusysign());
function setupFunc() {
document.getElementsByTagName('body')[0].onclick = clickFunc;
hideBusysign();
}
function hideBusysign() {
document.getElementById('busysign').style.display ='none';
}
function showBusysign() {
document.getElementById('busysign').style.display ='inline';
}
function clickFunc(eventData) {
var clickedElement = (window.event) ? event.srcElement : eventData.target;
if (clickedElement.tagName == 'BUTTON' || clickedElement.tagName
== 'A' || clickedElement.parentNode.tagName == 'A'
|| (clickedElement.tagName == 'INPUT' && (clickedElement.type ==
'BUTTON' || clickedElement.type == 'SUBMIT'))) {
showBusysign();
}
}
</script>

wicket supports global javascript event handlers for this. either
search the list or look inside wicet-ajax.js, i cant recall them off
the top of my head.
