JQuery :: Exceptions Inside Callbacks Are Silently Ignored?

Safari Failing Silently
Aug 30, 2006The stuff I've built recently works (in the sense that it does what I'm
expecting it to do without any errors or warnings) in IE and FF but
fails silently in Safari. I don't have a Mac to test on. I write some
stuff and send it to the client who tests and reports back.
I don't do any browser sniffing, I test for a feature for I try to use it...
Are there any known oddities about scripting for Safari that might
possibly help me out.
Silently Upload File Using Hta (hypertext Application)?
Jun 29, 2010I've got a pc which will hold some log files, and I want to get them onto my server.Rather than use a combination of batch scripts, ftp, and cron jobs, I thought I'd try using an hta htpertext application on the local machine, to upload the log file. So I'm trying to do a hta file that will upload a specified file via a self-submitting (javascript), then close itself, but I'm having 2 problems:1. Specifying the file name as the value of the file in the form doesn't seem to have any effect. The form comes trhough with a blank field.2. On submitting the form to the server, it opens an IE window to view the returned page (even if it's blank). If I ran the script every 10 minutes or whatever, the screen and memory would soo get full.Here' s the code I'm using:
Code:
<form enctype="multipart/form-data"
action="http://myserver/form.php"

JQuery :: Ajax Callbacks Not Being Called?
May 17, 2010I'm having problems with callbacks in the code below:
$.ajax({
dataType : 'jsonp',
jsonpCallback : 'get_json',
success : function(d) { alert(d); },
error : function() { alert("ouch"); },
url : data_url
})}
I have verified that the server is returning valid json. My jsonpCallback is called, but neither the success nor the error callbacks are. I'm stumped by this.

JQuery :: Prevent The Multiple Callbacks?
Dec 21, 2010how to use jQuery I created my own AutoComplete Textbox (although there is one in the jQueryUI Lib). The users types something in a textbox and after 3 characters, the getJSON method is beeing called. This processes the data by calling another site and after received the data, it displays the result in a div tag.If a user types something, it automatically searchs - my problem is the delay. Because if a user continuous, he will already receive (delayed) results - so far it works as designed. My question is, how can I stop the other callbacks of being processed and only receive and display the details of the last callback?

JQuery :: Loaded Up New 1.4 And Now Sucess Callbacks Don't Work
Jan 16, 2010Really excited about the new 1.4 release. Looks like a lot of good stuff. Anyway, I've been using the json format to pass data back from the server and after upgrading to 1.4 I'm getting the parsererror, even when I simplify my response to something like:

JQuery :: Continuation-style Programming / Are There Constraints On Fx Callbacks
Feb 18, 2011The documentation on e.g. the fadeIn() method does not specify any constraints on the callback argument. Does that mean that 'anything will work'? Specifically, is recursion allowed?I want to know whether jQuery design has deliberately taken this into account. Yes, I can read the source code. No I don't plan to do so (for now), since I consider it an essential gap in the documentation.[code]

Apr 6, 2010I am trying to develop a iGoogle-like dashboard that uses JSONP to get the content of each widget from other (trusted) sites.Each widget is a div that will take care of getting its content using $.ajax() and use the callback to update the div with the html content returned with JSONP.The problem I have happens only in Firefox (I'm using 3.6.3):when a site is unavailable or takes longer to return the JSONP content for a widget, it seems that the callback for the other widget does not get executed. All the widgets stay in the "loading" state although I'm sure they have all received the answer.What's puzzling is that if I hit the "stop" button of Firefox, the content of the other widgets get displayed (ie. their displaying callbacks get executed).
If the calls are asynchronous, what prevents Firefox from executing the callbacks for the other widgets once the response is received?Do you have any idea of what's happening and if there's some way around this?
JQuery :: Switched To 1.6.1 Immediately The Success Callbacks Of Functions Did Not Trigger?
May 13, 2011There is probably something going on in my environment but when running 1.5.2, jquery runs and behaves fine. When I switched to 1.6.1 immediately the success callbacks of ajax functions did not trigger. I did not see the release notes mention anything new regarding that.
This includes
$.post("url", function() { console.log("will i get printed?"); });
Here is a code sample which fails
$(".foo").click(function(e) {
var link = $(this);
e.preventDefault();[code].....
The callback function for the ajax is never invoked.As part of my application, I have the following ajax setup going
$.ajaxSetup({
'beforeSend': function(xhr) {xhr.setRequestHeader("Accept", "text/javascript")}
});

View 3 Replies View RelatedTurn Asynch Callbacks Into Synchronous Flow?
Jul 16, 2009I need to do something unusual. Say a user is browsing my site, and before they navigate away, I need to perform some actions like logging them out, for which they would need some data from the server. On onunload, a SJAX request (AJAX with that parameter as false) is issued, code flow hangs, and when the result comes in, code flow resumes and does what it needs to. If AJAX were used, the script would unload and never get the callback. Ok. So that's what I want. The problem is that I'm dealing with something other than an XMLHttpRequest object, and I can't simply supply a false parameter to the request function. I'm looking for some way to wrap an asynchronous routine of this object into a synchronous one. If call var result = myobject.get(data_to_send), code flow here hangs WHILE myobject calls this funky XMLHttpRequest-like object in asynchronous mode, waits for the callback, the callback is called, and myobject returns the result. So code stops synchronously outside of myobject.get, but waits asynchronously inside.

AJAX :: Callbacks And Parameters From Outside The Scope Of The Callback?
Feb 9, 2011This could appear under Ajax, for example, you could have multiple objects that make a singular ajax call (say an RPC-like request) and you need to update the object that made the call during the callback with the result, but it doesn't have to be. The particular problem I'm thinking about happens to be ajax, particularly with multiple objects accessing the same ajax request (meaning I can't use a global or temporary variable).
One way that seems like it would work (just thinking about it in my head), is to create a hash, and to pass the key through the request, store the key in the response, and pick it up on the callback side. Then remove the item from the hash when done.
Asynchronus Calls And Callbacks To Object Orientated Code
Jul 20, 2005This might be a bit tricky. I want to call a method of a class using the setTimeout code, ok, can do this like this:
var instance = this;
timerID = window.setTimeout( function() { instance.Method(); }, 1000);
Now I want to call a method a number of times from with the class and when they
have all finished I want a second method to be called, I don't want the methods
themselves to be altered, i.e. I want this to be generic.
Here was my idea:
var timerCounter = 0
function CallFunc(func, callbackFunc)
{
timerCounter--;
if(timerCounter == 0)
{
callbackFunc()
}
}
function DoAsyncRequest(func, callbackFunction)
{
timerCounter++;
return window.setTimeout( CallFunc(func, callbackFunction), 1);
}
You would call this using something like:
timerId = DoAsyncRequest(this.method(), this.method2());
How could I do this, tryed using eval to no avail. I just don't know the
language well enough yet.
JQuery :: Form Plugin - Reference To The Form In Callbacks?
Jul 26, 2007I needed access to the form that's being submitted in the options.success() function (in order to hide the form after successful submission). I ended up modifying line 222 in jquery.form.js. I added $form as the third argument for all callbacks, like so:
options.success = function(data, status) {
for (var i=0, max=callbacks.length; i < max; i++)
callbacks[i](data, status, $form); // added $form as third argument.
};
Is there a better way of accessing the form from the callbacks or would the plugin developer(s) consider adding this or another similar modification to the code?
JQuery :: Managing "return" In Callbacks?
Sep 8, 2010When JQuery initiates an action (e.g. an Ajax PUT) it sets up a callback to handle processing the event when the time dependent action completes. Since the callback operates as an independent thread, it cannot return to a calling routine via the "return" instruction. Is there a way to preserve the context somehow to return to a calling routine? Perhaps another type of callback event?

Apr 11, 2007consider the next code:
var obj = {};
with(obj) {
var x = 10;
}
print(x);
print(obj.x);
It prints 10 and undefined. Here, one could expect that obj.x get the
value 10. But it's not the case, because variable declarations are
placed at the start of function code (or global code), so the
previous code is equivalent with:
var obj;
var x;
obj = {};
with(obj) {
x = 10;
}
print(x);
print(obj.x);
You can clearly see now that x is placed in the outer context. But
consider the next:
var obj = {};
with(obj) {
eval("var x = 10;");
}
print(x);
print(obj.x);
I was expecting that obj.x would get the value 10 here. But no, it
gives the same output as the previous code. I tested it with
spidermonkey, kjs and ie jscript. Looking at the ECMA spec, I could
not find anything that describes that behaviour. Code:

<div id="top"><h3>Title</h3</div>
<div class="desc">

I want to click on any h3-tag and the jquery should open the next div with class desc. At the moment I use this script:
$(document).ready(function(){
$('.desc').hide();
$('h3').click(function() {
$(this).next('.desc').toggle(400);
return false;
});
});
I absolutly dont know what to change inside the script to affect the next div with class desc.
