how 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?
I have a form which is submitted via $.post(). This posts data to the server script and then a response is sent back to the client script. I would like to prevent the execution of this post for 10 seconds after the first execution. This function is for a quick reply method, so naturally i dont want people to post replies every second, therefore i would like an interval between quick replies to discourage multiple spamming.
I am working on a project that relies heavily on AJAX calls, they are done in dozens of places. There are a number of places where I would want to prevent the user from submitting information multiple times (form submissions etc ). I am trying to think of the best way to accomplish this.
I could simply disable the element that starts the AJAX call upon the first click and re-enable it upon completion of the call. I have also seen examples of developers using a class to handle ajax calls that store an identifier for the call and if it is in progress any new calls with the same identifier will be ignored.
I built an application that open a modelessDialog. my question is can i replace the modelessDialog content on a click in the parent window. i need this in order to prevent multiple modelessDialog to be open. i need to get to a status that only one modelessDialog is open and if the user try to open a new one then the content of the already open one is replaced, or the modeless that is already open will be closed automatically and then a new one....
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.
Really 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:
In php I've been using:
To set the header.
Guess I'm stuck using the older version until I find a solution.
The 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]
I 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?
There 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
I 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.
This 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.
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() } }
I 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?
When 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?

Bit of a noob question, but I'm using the following code to get a menu tab to highlight/switch classautomatically based on the id of the page in the querystring. All is working well until the page ids hit double digits. Subsequently a menu with the link "p=10" and above will highlight when "p=1" in the location bar. How should Iamend the code to prevent this partial match? The menu item links always end after "p="; there are no furtherkeys in the querystring toact as a delimiter.

I have content that loads into a div and in every browser except IE it renders fine. In the wonderful IE it comes in jagged...sometimes it "snaps" after and looks normal but for the most part its all jagged. The page is a white bg with text rendering into of it. How can I fix this so it looks normal? </SPAN></FONT></DIV>
I have this function:$("input[type='text']:order").keyup(function var v (this).val() replace(/D/g,''); // removes non numbers $('#total_buyed').val( v * 2.75 ); }); The function is working correctly but when I press any key the same operation is calculated.How to avoid this? See online at [URL]..
