[Proto-Scripty] Re: Pulse effect sometimes stopping on darkened version
Thanks for that walter. I played around and it seemed that even if you
queue pulstes, you can run into issues. The solution I found in the
end is instead of queueing pulsates, queue an opacity effect of 0.1
duration, from 1 to 1. Queueing the pulsate is annoying anyway, as if
you spam the link, it queues and goes on for ages.
Cheers anyway

Identify assigns an ID to the element if none exists, and that ID will
persist until the page is done processing. Basically, it's a throw-
away line to ensure that if the element that fired the event doesn't
have an ID, the rest of your code doesn't go sproing. You could just
as easily throw in an outer if(elm.id) test wrapped around the inner
parts.
Queue works by allowing you to define as many different queues as you
like, and for each queue, stacking up the effects that are fired
within it so that they have to complete before another effect can
begin. By passing the ID of the element as the queue name, you give
each element its own stack of effects, keeping another effect from
messing with it and giving each effect time to complete fully.

[Proto-Scripty] Re: Pulse effect sometimes stopping on darkened version
The app as a whole is complicated, but what is driving the effects
isnt.
It's simply html with a plain old link:
a [...] onmouseover=attractAttention
('pb_user_mylocs_button');link/a
and the attractAttention function is a one-liner:
function attractAttention(obj){
new Effect.Pulsate(obj, { pulses: 3, duration: 1});
}
Apart from the Click a Location Marker link, which also moves the
map etc.
Basically, for a demo, rollover just the last link (My Locations)
repeatedly.
As I said, that effectively executes one line:
new Effect.Pulsate($('pb_user_mylocs_button'), { pulses: 3, duration:
1});
It's clearly not my code. If you go to
http://wiki.github.com/madrobby/scriptaculous/effect-pulsate
and click the demo repeatedly, you get the same problem.

Is that big lump of code in the middle (begins with unescape) what you
are using to drive any of these effects?

[Proto-Scripty] Re: Ajax functions not working inside classes.
Great, that worked. I didn't realise this could be something else... Also, bear in mind that I only started using prototype for this project yesterday. Hell, I ripped it out and put it back in since I made the first post - hence a lot of the code does not use prototype properly (Though a search and replace for document.getElementsByID( to $( is quick and easy...) I have firebug installed already, though I have only ever used it for CSS inspection, I will have to investigate how to use it to debug JS. Many thanks for taking the time to download my code and help set me straight.

[Proto-Scripty] Re: Ajax functions not working inside classes.
The idea of Placebook is social networking for places. Sort of like if you could have a facebook or twitter account for a place. People can log in and add locations, then people can make posts on it's wall, or add tags to the location to denote activies and social groups associated with that place (eg a cafe may have a food tag and a tag that linked to a book club that met there on tuesdays). As my uni project I wish to develop basic functionality, but this is something I will likely be persuing even I leave university, though not really as a profit making venture, more as one of those things you just want to use yourself ;) Ultimately, I want to write a mobile interface (This may happen as a uni project) and allow import / export of GPS trails, interfacing with TomTom and other mobile navigation systems etc etc. I managed to buy placebook.tv and placebook.mobi, so keep an eye out there!

For future reference,
document.observe('resize',winResize);
Never fires. Maybe because the document as a whole has not been
extended?
However,
Event.observe(window, 'resize', winResize);
worked fine.

[Proto-Scripty] Ajax functions not working inside classes.
The following code works:
new Ajax.Request('somefile.php',{
method:'get',
onSuccess: function(transport){
var response = transport.responseText || no response text;
alert(Success! \n\n + response);
},
onFailure: function(){
alert('Something went wrong...')
}
});
however, if you encapsulate the code inside a class:
var myclass = Class.create({
cut and paste exact same code into here
});
var thisclass = new myclass();
thisclass.submit();
The code ALWAYS comes back with an empty response when you encapsulate
the AJAX call :(
Any ideas what I am doing wrong? is prototype broken?

[Proto-Scripty] Re: Ajax functions not working inside classes.
Thanks TJ, I tried to make a self-contained version, so I ripped out prototype and did the same thing with object literals, and I still had issues, so clearly it wasnt prototype. In the end I figured out that the button which fired off the AJAX request (ie the Submit button) was inside a form (I did not want it to actually do an HTTP POST submission of the form, just call JS code) and I had not disabled the form with onsubmit='return false', so when I clicked submit, it was submitting the form, thus destroying the button that made the AJAX call before the reply came back. I had noticed that putting an alert or delay into the script caused it to work and was tearing my hair out - obviously the delay stopped the button being destroyed long enough for the AJAX request to come back. Oh the joys of Asynchronous web coding. I now have a slightly different problem, with the same button... Once the AJAX reply comes back that the data was updated, I want to destroy the form. But it won't let me. I guess for a similar reason to my explanation above - the button started the call, and it is in the response code that I wish to destroy it, so it technically hasn't finished yet. I hope that all makes sense. If not, I will try and rig some self contained code using the system you linked - I guess for the ajax request I could just get it to grab a css file or something off the server? -- You received this message because you are subscribed to the Google Groups Prototype script.aculo.us group.

[Proto-Scripty] Re: Ajax functions not working inside classes.
I have put up a version on my web server. http://www.evilc.com/pb The JS file is at http://www.evilc.com/pb/placebook.js - the code you are interested in will be in the pb_editloc object near the end. The HTML of the form is at http://www.evilc.com/pb/templates/pb_add_location.html (the php grabs this and passes it to the JS in the templates[] array) Here is how to replicate: 1. Click Add Location in the top right of the map window - This calls pb_editloc.add 2. Click the Point radio button in the form that appears. You are now in the form where the problem lies - with the submit/ cancel buttons at the bottom. Click on the map to place a marker and type a name in the name box to make the submit button light up. Once you click submit, it adds the location to the back end database fine, but when it calls pb_editloc.deleteform in the AJAX callback function (in pb_editloc.submit), it fails. Notice if you click Cancel, it kills the form fine. This ultimately calls pb_editloc.deleteform just like submit does, but I am presuming as there is no AJAX call still running that the button started, the button can be deleted.
