[jQuery] Re: Way to convert DOM event to jQuery event?
What about using the metadata plugin and storing data in the class
attribute? A little hackish (in HTML5 can use the data attribute, which is
more proper...):
http://plugins.jquery.com/project/metadata
In addition to rel, you could also use the title attribute on the anchor,
no?

[jQuery] ANN eyedropper color picker plugin
[cross posted from the plugin list, which seems to have died in February] Hey folks, I've been absent from the jquery lists for quite awhile, but just recently had the opportunity to build a cool little plugin for a project I'm working on so I decided to release it to the public. This plugin acts as an eyedropper-style color picker, allowing a user to select a color by clicking a pixel in an image. The plugin replaces selected img elements on the page with a canvas element, and provides click, mousemove and mouseout event callbacks. The callback is sent a color object (describing the color under the mouse for the event). It also shows a little hovering preview of the color near the cursor when over the image. You can find it on github with a simple demo included: http://github.com/sstrudeau/jquery-dropper I'm hoping to receive some feedback on things like: * callback function naming conventions * which other arguments would be useful appropriate to send via the callback * should I instead (or also) trigger events instead/as well as offer callbacks? * any best practice examples for making something like the color hover chip style-able, optional? * any other feedback No live demo yet -- but if I hear a clamor, I might find a place to tuck one. Notable limitations: doesn't work on IE (the VML canvas hack doesn't offer pixel-level access to images) and images must be hosted from the same domain as the origin page (canvas security limitation).

[jQuery] Re: ANN eyedropper color picker plugin
This wouldn't be too difficult to turn into a greasemonkey script. It
wouldn't work for images that are hosted from a domain other than the parent
page, however, which is a frequent case; Firefox will throw canvas security
exceptions for every img element not in the domain if you do
$('img').dropper(). You could probably do a $('img').each() loop and check
that the src attribute is in the page domain before making the image
pickable, but you would only be able to pick from a subset of (possibly
0) images on the page.
You could also turn it into a bookmarklet a la Karl Swedberg's jquerify
bookmarklet (same caveats apply, greasemonkey not required):

Yes. That creates a single scope for all the plugin code and allows you to

doesn't use the $() alias for jQuery() (e.g., because they also use

[jQuery] Re: Remote JSON Ajax call - error function not called
No, I don't think there is. When you use JSONP or other script-tag
techniques, jQuery creates the script tag DOM element, but I don't think it
can get any response if the script fails to load. Whatever happens, happens.
It's technically possible to simulate a timeout by wrapping the JSONP
callback function, wait for the timeout period, and then check to see if the
callback function set some known value. If it hasn't set this value after
the defined timeout interval, destroy the callback function and script tag,
and trigger a timeout. I built a custom JSONP function that does this since
jQuery didn't back when I needed it. I've been meaning to look at core and
contribute a patch to simulate timeouts for JSONP calls, but the code is
pretty wacky so I haven't had time to parse it and understand how a patch
like this might work. Not sure if the state of affairs has changed since
1.1.2...

not happen*. No function is called. If, however, you change the URL
to be a local address (but still incorrect) then the error function
*is* called.
I'm sure I'm missing something fundamental!! But is there a way to

You can also extend that to do some kind of alternate logging if
console.logisn't defined.
E.g.,
if(typeof window.console == 'undefined') {
window.console = {
log: function(msg) { $('div#log').append('p'+ msg '/p'); }

Well, in that specific code, you should be able to just

[jQuery] Re: Using JSONP...I'm clueless.
Ryura,
You don't need to use getJSON but you do need to find out exactly how the
JSONP service you are using expects the callback function to be specified in
the URL. The echo you provided shows that the service you are calling is
not prepending the JSON encoded object with the name of the function.
Normally the GET param for a JSONP callback function is simply callback
-- I don't recall if jQuery will append this by default if it doesn't see a
? at the end of the provided URL -- but it can be anything. For example, it
could be jsonpCallback, in which case your URL should be something like:
http://somedomain.net/jsonp/selection.php?jsonpCallback=?
jQuery will autogenerate your callback function (which eventually will
invoke your success callback) and replace the trailing ? with the
autogenerated function name.

From the docs http://docs.jquery.com/Ajax/jQuery.getJSON#urldatacallback
As of jQuery 1.2, you can load JSON data located on another domain if
you specify a JSONP callback, which can be done like so: myurl?
callback=?. jQuery automatically replaces the ? with the correct
method name to call, calling your specified callback.
This is a piece of working code:
$.getJSON(http://ws.geonames.org/searchJSON?q=+m.editSearch

When queryString starts with a ? it will get converted to

But I see no way to prevent that from happening.
Now... one might suggest that I should avoid a leading ? in my option
names. But I am taking them from input boxes and ? is a valid thing
for a user to type. Unfortunately there seems to be no good way to
escape the string to prevent this behavior (without teaching the
called code how to unescape it).
Also, the docs don't mention that the =? escaping happens to a json
dataType... I see it for jsonp.
Is this behavior intentional? If so, there should be a way to
suppress it or at a way for the calling code to escape the values to
cause a leading ? to be passed to the server.

So I use the script tag technique (create script tag, assign src and
append to head) to do so.
But unlike xmlhttprequest, I cannot get any response status from it.
So I just wonder if there is anyway I can detect if the remote script is
not available?
I tried to use try-catch, which works on Firefox but not IE. Code:
$(document).ready(function(){
try{
var s = document.createElement(script);
s.type = text/javascript;
s.src = http://thisurldoesnotexist/dsfsdlfjk.js ;
document.appendChild(s);
}
catch(e){
alert(any error);
}
});

Best Regards,
Jacky

[jQuery] Re: Counting the number of child elements that a div has
It should. I just typed this into my Firebug console on a page including
jQuery:
$('body').append('div id=test/div');
$('#test').append('p'+ $('#test').children().size() +'/p');
$('#test').append('p'+ $('#test').children().size() +'/p');
$('#test').append('p'+ $('#test').children().size() +'/p');
Seemed to work as expected

[jQuery] Re: $.post() and CI inquiry
* CI = CodeIgniter, I presume
Steve,
I'm not sure I understand your question, but when you call:
$('#pendingUsers').load('index.php/meduser/check_pending_users');
It should load the HTML returned by index.php/meduser/check_pending_users
into whatever element has the id pendingUsers ... CI doesn't need to know
about the target DIV. It just needs to return some HTML.
If you need to do something differently depending on the result of
check_pending_users, that becomes a little more complex.

My controller looks like this:
function pull_user_information()

$id = $this-input-post('id');
$data['query'] = $this-db_users-query('select * from tbl_signups
where ID=$id'
);
$this-load-view('default/meduser_useraccordny_view', $data);
}
I'm trying to populate the rel of the anchor tag into $id and using that
to query the database.
I can then pass that into the meduser_useraccordny_view, however I'm still
not entirely sure how to populate the particular div.
Any assistance would be appreciated!

I ended up giving up (for now) and switched to using thickbox for the

embed the ajax stuff that the modal needs to do in the parent page,
because the functionality is something that can be opened from any page
in the site, so I want it to be contained in the code for the modal that
is opened.

Hi All,
Anyone know if it's possible to make ajax calls from inside a jqModal

trigger:'a.jqmTrigger',
ajax:'/pos2/purchase/quick_change.cfm',
target:$('#users'),
modal:true,
onShow:function(h){
h.w.show();

});
a id=aUserSwitcher href=## class=jqmTriggerSwitch/a
div id=userSwitcher class=jqmWindow
style=width:600px;height:500px
div id=users/div
/div
and have included jqModal.js and jqModal.css in the calling page, then
in the quick_change.cfm file I'm doing additional ajax calls:
var url = something.html
$.get( url, function(template){
etc
but that $.get() never fires AND the userSwitcher div loads up real
quick, then the whole page goes white and goes nowhere: it just spins.
Bug? Is this possible via jqModal? I'm pretty sure I had something
like this working with the thickbox plugin a few months ago, but the
jquery.com site was down earlier tonight when I went fishing for the
latest code to try to use, so I tried using jqModal.
TIA,

[jQuery] Re: How to Rotate an Image 90 Degrees
I'm developing in Coldfusion, by the way. But, I don't think I can use a server side script for this as I need it to update without a page refresh... There are a number of ways you could do this with a .ajax or similar call. E.g., let's say you write a coldfusion script that accepts as parameters the image path and some rotation parameters (let's say 90, 180 or 270 for degrees of rotation to the right). E.g., http://example.com/rotateimage.cf/?image=foo.jpgrotate=90 ... and have that script rotate the source image, save it to disk, and return the new image (you can set headers to deliver a straight-up image from that URL). If it makes sense for your app, you could cache the rotated images and check the cache first ... but those are details. Then, for example, onclick you could replace the src attribute of an img tag with the rotated version of the URL. Lots of details here, but that might work. You could also have the CF script process the image and return the direct URL to the static file and replace it with that, instead... Scott On 6/27/07, cfdvlpr [EMAIL PROTECTED] wrote: I've taken a look at swfIR and that seems to work.
