  • How can I implement a jquery ajax form which requests information from a web api via a php request?

    - by Jacob Schweitzer
    I'm trying to implement a simple api request to the SEOmoz linkscape api. It works if I only use the php file but I want to do an ajax request using jquery to make it faster and more user friendly. Here is the javascript code I'm trying to use: $(document).ready(function(){ $('#submit').click(function() { var url=$('#url').val(); $.ajax({ type: "POST", url: "api_sample.php", data: url, cache: false, success: function(html){ $("#results").append(html); } }); }); }); And here is the part of the php file where it takes the value: $objectURL = $_POST['url']; I've been working on it all day and can't seem to find the answer... I know the php code works as it returns a valid json object and displays correctly when I do it that way. I just can't get the ajax to show anything at all!!

  • How can I add more Android home screens?

    - by LKM
    It seems my HTC Magic running Android 1.5 (Cupcake) has three home screens I can switch between. I can't find any kind of option to add additional home screens (the "home screen" menu only lets me add Widgets, Shortcuts and Folders or change the Wallpaper). Is there any way I can add more?

  • Mouseup not working after mousemove on img

    - by leyou
    I'm trying to do a simple drag script. The idea is to save the position when the mouse is down, update the view while the mouse is moving, and stop when mouse is up. Problem, mouseup event isn't working properly. See the code: var target = $('a') var pos = 0; var dragging = false; $(document).mousedown(function(e) { pos=e.pageX; dragging = true }) $(document).mouseup(function() { dragging = false }) $(document).mousemove(function(e) { if(dragging){ target.css('left', e.pageX-pos); } }) ? Why mouseup works with a "a" tag: http://jsfiddle.net/leyou/c3TrG/1/ And why mouseup doesn't work with a "img" tag: http://jsfiddle.net/leyou/eNwzv/ Just try to drag them horizontally. Same probleme on ie9, ff and chrome.

  • Must a Language that Implements Monads be Statically Typed?

    - by Morgan Cheng
    I am learning functional programming style. From this link http://channel9.msdn.com/shows/Going+Deep/Brian-Beckman-Dont-fear-the-Monads/, Brian Beckman gave a brilliant introduction about Monad. He mentioned that Monad is about composition of functions so as to address complexity. A Monad includes a unit function that transfers type T to an amplified type M(T); and a Bind function that, given function from T to M(U), transforms type M(T) to another type M(U). (U can be T, but is not necessarily). In my understanding, the language implementing monad should be type-checked statically. Otherwise, type errors cannot be found during compilation and "Complexity" is not controlled. Is my understanding correct?

  • Kernel thread exit in linux

    - by Raffo
    Hi guys, I'm here to ask you the difference between a process and a thread in linux. I know that a thread for linux is just a "task", which shares with the father process things that they need to have in common (the address space and other important informations). I also know that the two are creating calling the same function ('clone()'), but there's still something that I'm missing: what really happens when a thread exit? What function is called inside the linux kernel? I know that when a process exits calls the do_exit function, but here or somewhere else there should be a way to understand if it is just a thread exiting or a whole process. Can you explain me this thing or redirect to some textbook?? I tried 'Understanding the linux kernel' but I was not satisfied with it. I'm asking this thing because a need to add things to the task_struct struct, but I need to discriminate how to manage those informations for a process and its children. Thank you.

  • Convert a "by" object to a data frame in R

    - by lorin
    I'm using the "by" function in R to chop up a data frame and apply a function to different parts, like this: pairwise.compare <- function(x) { Nright <- ... Nwrong <- ... Ntied <- ... return(c(Nright=Nright, Nwrong=Nwrong, Ntied=Ntied)) } Z.by <- by(rankings, INDICES=list(rankings$Rater, rankings$Class), FUN=pairwise.compare) The result (Z.by) looks something like this: : 4 : 357 Nright Nwrong Ntied 3 0 0 ------------------------------------------------------------ : 8 : 357 NULL ------------------------------------------------------------ : 10 : 470 Nright Nwrong Ntied 3 4 1 ------------------------------------------------------------ : 11 : 470 Nright Nwrong Ntied 12 4 1 What I would like is to have this result converted into a data frame (with the NULL entries not present) so it looks like this: Rater Class Nright Nwrong Ntied 1 4 357 3 0 0 2 10 470 3 4 1 3 11 470 12 4 1 How do I do that?

  • How does one implement a truly asynchronous java thread

    - by Ritesh M Nayak
    I have a function that needs to perfom two operations, one which finishes fast and one which takes a long time to run. I want to be able to delegate the long running operation to a thread and I dont care when the thread finishes, but the threads needs to complete. I implemented this as shown below , but, my secondoperation never gets done as the function exits after the start() call. How I can ensure that the function returns but the second operation thread finishes its execution as well and is not dependent on the parent thread ? public void someFunction(String data) { smallOperation() Blah a = new Blah(); Thread th = new Thread(a); th.Start(); } class SecondOperation implements Runnable { public void run(){ // doSomething long running } }

  • adding numeric values of variable number of forms

    - by user306472
    I'm trying to use jquery to loop through a block of forms that contain numeric data and add it all up to be displayed in a form with id grand. I have the ability to dynamically add new forms, so the number of forms I'm looping through will change. Here's my jquery code I wrote that isn't working for whatever reason: $('#table').delegate('input#grand', 'focus', function(){ var grand = $(input.expend).map(function(){ return this.value; }); $(grand).each(function(){ var g = 0; g+= $(this); $('input#grand').val(g); }); });

  • How do you replace many characters in a regex?

    - by macca1
    I am sanitizing an input field and manually getting and setting the caret position in the process. With some abstraction, here's the basic idea: <input type="text" onkeyup"check(this)"> And javascript... function check(element) { var charPosition = getCaretPosition(element); $(element).val( sanitize( $(element).val() ) ); setCaretPosition(element, charPosition); } function sanitize(s) { return s.replace(/[^a-zA-Z0-9\s]/g, ''); } This is working fine except when a character does actually get sanitized, my caret position is off by one. Basically I'd like a way to see if the sanitize function has actually replaced a character (and at what index) so then I can adjust the charPosition if necessary. Any ideas?

  • MS Access "#Name?" in unbound field on SOME machines

    - by alkorya
    I have a datasheet form bound to table. I added 2 unbound fields and set their Control Source properties to user defined VBA functions: 1. ConcatRelated (http://allenbrowne.com/func-concat.html) 2. Custom function that returns a string: Public Function GetLowestSatatus(LookupField As String, JSAID As Integer) As String On Error Resume Next GetLowestSatatus = DLookup(LookupField, "JsaStatuses", "ID=" & DMin("StatusID", "Tasks", "JSAID =" & JSAID)) End Function It works fine on my and some other machines but there are machines I got "#Name?" in these 2 unbound fields. All machines configured identically. Any ideas? Thank you!

  • Interrupting `while loop` with keyboard in Cython

    - by linello
    I want to be able to interrupt a long function with cython, using the usual CTRL+C interrupt command. My C++ long function is repeatedly called inside a while loop from Cython code, but I want to be able, during the loop, to send an "interrupt" and block the while loop. The interrupt also should wait the longFunction() to finish, so that no data are lost or kept in unknown status. This is one of my first implementation, which obviously doesn't work: computed=0; print "Computing long function..." while ( computed==0 ): try: computed = self.thisptr.aLongFunction() except (KeyboardInterrupt, SystemExit): computed=1 print '\n! Received keyboard interrupt.\n' break; (p.s. self.thisptr is the pointer to the current class which implements aLongFunction() )

  • Java, how to trace functions called

    - by user435657
    Hi all, I want to trace the beginning [& ending] of functions called in Java, like the following code: public void foo() { System.out.println("begin of foo()"); ... System.out.println("e-n-d of foo()"); } But maintaining of the dump code System.out.println is something tedious and error-prone, for there may be tens of thounds of function in an class. Any good idea can ease this work? I don't want dump statements all over the file. Implementation of both or one of the beginning & ending traces is perferd. But, if impossible, recordings of that the function has been called is also helpful. I mean not care the exact beginnig and ending, just tell that the function has been called.

  • Connecting data to a GUI - OOP

    - by tau
    I have an application with several graphs and tables on it. I worked fast and just made classes like Graph and Table that each contained a request object (pseudo-code): class Graph { private request; public function setDateRange(dateRange) { request.setDateRange(dateRange); } public function refresh() { request.getData(function() { //refresh the display }); } } Upon a GUI event (say, someone changes the date range dropdown), I'd just call the setters on the Graph instance and then refresh it. Well, when I added other GUI elements like tables and whatnot, they all basically had similar methods (setDateRange and other things common to the request). What are some more elegant OOP ways of doing this? The application is very simple and I don't want to over-architect it, but I also don't want to have a bunch of classes with basically the same methods that are just routing to a request object. I also don't want to set up each GUI class as inheriting from the request class, but I'm open to any ideas really.

  • INET_ATON() and INET_NTOA() in PHP?

    - by blerh
    I want to store IP addresses in my database, but I also need to use them throughout my application. I read about using INET_ATON() and INET_NTOA() in my MySQL queries to get a 32-bit unsigned integer out of an IP address, which is exactly what I want as it will make searching through the database faster than using char(15). The thing is, I can't find a function that does the same sort of thing in PHP. The only thing I came across is: http://php.net/manual/en/function.ip2long.php So I tested it: $ip = $_SERVER['REMOTE_ADDR']; echo ip2long($ip); And it outputs nothing. In the example they gave it seems to work, but then again I'm not exactly sure if ip2long() does the same thing as INET_ATON(). Does someone know a PHP function that will do this? Or even a completely new solution to storing an IP address in a database? Thanks.

  • Jquery code working in all browsers apart from FF

    - by alan
    Hi, I have written the following jquery sitting in the head tags of my HTML It is supposed to bring the image that is being hovered over to full opacity and slide another image over it from the right, then return when un-hovered. <script type="text/javascript"> $(function() { $('ul#img-nav li').css({ "opacity": .5 }); $('ul#img-nav li').hover(function() { $(this).stop(true).animate({"opacity":1}); $(this).children('.overlay').stop(true).animate({"left" : "18px" }); }, function() { $(this).stop(true).animate({"opacity":.5}); $(this).children('.overlay').stop(true).animate({"left" : "180px" }); }); }); This works fine in Safari, Chrome, IE (7,8) but not in FF 3.6. Any suggestions why this might be? Many thanks

  • What are these lines doing?

    - by Montecristo
    I'm starting learning javascript for a project, I've found a script that does a part of what I need to do, I'd like to know how it works, both for me and in case it needs to be modified. Originally it was used inside the page, now I've put it in a file on its own and does not work anymore, so I'm dividing it in parts, because I fail to get the whole thing. Here is what bother me most for now: 1) Is this a declaration a function? What is its name? How can it be invoked? (function() { //some code })(); 2) No clue of what is going on here var VARIABLE = VARIABLE || {}; 3) Am I defining a the implementation of methodCall here? Something like overriding a method in Java? VARIABLE.methodCall = function(parameter) { console.log("parameter was: " + parameter); }; Thank you in advance for your help.

  • How can I revert a 'draggable' upon failed AJAX request?

    - by Frank
    I have a draggable div, that needs to be dropped on a droppable. If it is dropped correctly, the droppable calls an AJAX request. If the draggable does not have a valid id or the AJAX request fails, the draggable should be reverted to it's original position. Is that something that can be done with jQuery?! Any help is greatly appreciated!! $("div.draggable").livequery(function(){ $(this).draggable({ revert: 'invalid', distance: 20 }) }); $("#trash").droppable({ tolerance: 'touch', drop: function(event, ui) { var item = ui.draggable; var id = item.attr('id'); if (id) { $.ajax( { type: "POST", url: "delete.php", data: "id=" + id, success: function(html) { if (html) { item.remove(); } else { // FAILED AFTER AJAX // is it possible to revert the draggable from here?? } } }); } else { // FAILED BEFORE AJAX // is it possible to revert the draggable from here?? } } });

  • How to add values to a JSON object?

    - by Damiano
    Hello everybody, I have created an array with: var msg = new Array(); then, I have a function that add values to this array, this function is: function add(time, user, text){ var message = [time, user, text]; if (msg.length >= 50) msg.shift(); msg.push(message); } As you can see, if the array has 50 or more elements I remove the first with .shift(). Then I add an array as element. Ok, the code works perfectly, but now I have to loop the msg array to create a JSON obj. The JSON object should has this format: var obj = [ {'time' : time, 'user' : user, 'text' : text}, {'time' : time, 'user' : user, 'text' : text}, {'time' : time, 'user' : user, 'text' : text} ] I mean...i have to loop msg array and then store all the values inside the JSON object. I do not know how to "concatenate" the element of the array inside json obj. Could you help me? Thank you very much in advance!

  • JavaScript Namespace Declaration

    I created a javascript class as follow: var MyClass = (function() { function myprivate(param) { console.log(param); } return { MyPublic : function(param) { myprivate(param); } }; })(); MyClass.MyPublic("hello"); The code above is working, but my question is, how if I want to introduce namespace to that class. Basically I want to be able to call the class like this: Namespace.MyClass.MyPublic("Hello World"); If I added Namespace.MyClass, it'll throw error "Syntax Error". I did try to add "window.Namespace = {}" and it doesn't work either. Thanks.. :)
