  • jQuery validator and a custom rule that uses AJAX

    - by thatweblook
    Hi, I read your reply regarding the jQuery validator where you outline a method to check a username against a value in a database. Ive tried implementing this method but no matter what is returned from the PHP file I always get the message that the username is already taken. Here is ths custom method... $.validator.addMethod("uniqueUserName", function(value, element) { $.ajax({ type: "POST", url: "php/get_save_status.php", data: "checkUsername="+value, dataType:"html", success: function(msg) { // if the user exists, it returns a string "true" if(msg == "true") return false; // already exists return true; // username is free to use } })}, "Username is Already Taken"); And here is the validate code... username: { required: true, uniqueUserName: true }, Is there a specific way i am supposed to return the message from php. Thanks A

  • C++ - dynamic pointer of array

    - by Eagle
    Hi to all, first i would like to say i am Newbie in C++. As part of my master thesis i am writing a program in C++ which also get as parameters the variables m and d (both integers). Were d is the power of 2 (this means 2^d elements). Parameter m define the number of possible interactions between one element and the total group (2^d elements). The number of possible interactions is computed as following: \kappa = \sum_{i=0}^m\binom{d}{i} (at present i generate vector of vectors for 2^d x \kappa, but my Prof. would like me to create different statistics to different m's. My first though was to to generate a dynamic array of m arrays of different sizes... Then i though of defining a 3-dim array with the biggest needed 2d array, but also program speed is important (e.g d = 20). i would like to ask for your advice how to define such kind of dynamic array that will also be fast. Regards

  • How can I get jsonp to play nice with my class?

    - by George Edison
    This whole jsonp thing is quite confusing... Here is what I want to do: I have a class DataRetriever The class has a method GetData GetData makes a jsonp request with the following code: var new_tag = document.createElement('script'); new_tag.type = 'text/javascript'; new_tag.src = 'http://somesite.com/somemethod?somedata'; // Add the element var bodyRef = document.getElementsByTagName("body").item(0); bodyRef.appendChild(new_tag); Now, the jsonp data from the server somesite.com can call a function in my code with the data. The problem is, how does the data get delivered to the instance of DataRetriever that requested it? I'm really stuck here.

  • Make jQuery-ui draggable handle cover entire page

    - by Acorn
    What would be the best way to make an element draggable when clicking anywhere in the window? Would I have to use a container <div> that covers the whole window? I tried making the body draggable but that didn't work. The problem with using a container <div> is that it moves and therefore doesn't cover the whole of the screen any more after it has been dragged. What about making a really vast container <div> that spans a large number of pixels in every direction so you would never get to the edge of it. Is that a bad idea? The idea (simplified) is to have a page with a square in the middle that can be dragged by dragging any part of the window. Here's a wonderfully unnecessary mockup :)

  • Display message when user leaves site

    - by Brian Rasmusson
    Hi, I'm looking for a way to display a message to the user if he leaves my site after only viewing one page. I found this (http://www.pgrs.net/2008/1/30/popup-when-leaving-website) clever solution, but it has a few flaws: staying_in_site = false; Event.observe(document.body, 'click', function(event) { if (Event.element(event).tagName == 'A') { staying_in_site = true; } }); window.onunload = popup; function popup() { if(staying_in_site) { return; } alert('I see you are leaving the site'); } It displays the message also when refreshing the page or using the back button. Do you know a better solution or how to fix it in the above code? I'm no javascript master :) My intention is to add the code on very specific landing pages only, and display the message when people leave the page without downloading my trial software or reading other pages on my site.

  • Loop throught form inputs

    - by Victor
    I have a form with lots of inputs. I want to get each id and value and then put them in $.load method. I tried this: $("#form input").each(function() { var name = $(this).attr("id"); var value = $(this).attr("value"); $.extend(params, { name, value }); }); and then use $.load("script.php", params); But obviously it doesn't work. In params I have only one element "name". And I'm not sure I should use extend method too.

  • Arrays in JavaScript

    - by caramel1991
    While reading a book about JavaScript I stumbled across an example: var names = new Array("Paul","Catherine","Steve"); var ages = new Array(31,29,34); var concatArray; concatArray = names.concat(ages); My question is, why doesn't the variable concatArray need to be define as a new Array() in order to store the concatenated data for both arrays name and ages , but when I try to treat the concatArray as an array by adding another line of code "document.write(concatArray[0])", it works just like an array and shows me the data stored in the first element. I just wonder why I'm not declaring the concatArray as a new array, yet it still works as one.

  • Security in API authentication

    - by Carlos
    We are in the process of revamping our server side API, and we need to manage security. Our current model requires that a credentials object (containing user, password, and pin) be included in each method invocation. Our development team, however, has decided that we should have session objects instead (which is fine by me), but the new credentials are just a GUID. This is very different from what I've seen in other APIs in our industry, so I'm a bit concerned about how secure the new model will be. I asked them if they had analyzed both alternatives, and they said they haven't. Does anyone know if there're any clear advantages, disadvantages, risks, etc. of using a set of credentials versus just one element (complex as it may be)? PS: the communication channel would be secure in either case, and it's separate from this particular topic

  • iPhone / NSArray : How do I format a text file to be read in using arrayWithContentsOfFile

    - by nickthedude
    I have several large word lists and I had been loading them in place in the code as follows: NSArray *dict3 = [[NSArray alloc] initWithObjects:@"abled",@"about",@"above",@"absurd",@"absurdity", ... but now it is actually causing an exc_bad_access error weirdly, i know it seems implausible but for some reason IT IS causing it. (trust me on this I just spend the better part of a day debugging this crap) Anyway, I'm looking to get these humongous lines of code out of my files but I'm not sure what the best approach is. I guess I could do a plist but I need to figure out how to automate the process. it be easiest if I could just use the text files I've been compiling so if anyone knows how I can format the text file so that the myArray = [NSArray arrayWithContentsOfFile: @"myTextFile.txt"]; will be read in correctly as one word per element in the array it would really be appreciated. Thanks, Nick

  • How To Switch To A Frame That Appears As A Pop Up Window

    - by chuanl
    I am using the following applications: Selenium 2.0 in C# Firefox I need to write a test that clicks a button and opens a frame as a pop up window. The frame does not have a name nor id. The source code in the frame starts with "html" instead of "frame". However, when you right click on the window, it shows that it is a frame. So, I think it is a frame instead of a window. I have tried the following code, but does not work: driver.SwitchTo().Frame(0) The error I get looks like below: error: No response from server for url http://localhost:7055/hub/session/126a4485-48cb-4230-b0b0-69c4169b1852/element/%7B706f4a88-56a7-4813-af1b-8e137ce676af%7D/click Please help. Thanks.

  • About enumerations in Delphi and c++ in 64-bit environments

    - by sum1stolemyname
    I recently had to work around the different default sizes used for enumerations in Delphi and c++ since i have to use a c++ dll from a delphi application. On function call returns an array of structs (or records in delphi), the first element of which is an enum. To make this work, I use packed records (or aligned(1)-structs). However, since delphi selects the size of an enum-variable dynamically by default and uses the smallest datatype possible (it was a byte in my case), but C++ uses an int for enums, my data was not interpreted correctly. Delphi offers a compiler switch to work around this, so the declaration of the enum becomes {$Z4} TTypeofLight = ( V3d_AMBIENT, V3d_DIRECTIONAL, V3d_POSITIONAL, V3d_SPOT ); {$Z1} My Questions are: What will become of my structs when they are compiled on/for a 64-bit environment? Does the default c++ integer grow to 8 Bytes? Are there other memory alignment / data type size modifications (other than pointers)?

  • Add version control to existing SQL Server database

    - by ederbf
    I am part of a development team currently working with a database that does not have any kind of source control. We work with SQL Server 2008 R2 and have always managed the DB directly with SSMS. It now has ~340 tables and ~1600 stored procedures, plus a few triggers and views, so it is not a small DB. My goal is to have the DB under version control, so I have been reading articles, like Scott Allen's series (http://bitly.com/9cJmGR) and many old SO related questions. But I am still unable to decide on how to proceed. What I'm thinking of is to script the database schema in one file, then procedures, triggers and views in one file each. Then keep everything versioned under Mercurial. But of course, every member of the team can access SSMS and directly change the schema and procedures, with the possibility that any of us can forget to replicate those changes in the versioned files. What better options are there? And, did I forget any element worth having source control of?

  • Show only one validation error-message using replaceWith

    - by timkl
    I am currently working with the jQuery validation plugin, and I want to show only one error-message before the form itself. Right now the validation shows all the error-messages on top of each others as they stack up, as you can see in my live example: http://timkjaerlange.com/foobar/stack-stuff/validate-test.html This is my jQuery: $(document).ready(function() { $("form").validate({ rules: { // bunch of rules here, left out to keep it simple }, messages: { // messages goes here }, errorElement: 'div', errorClass: 'error', errorPlacement: function(error, element) { error.insertBefore('form'); // this is what I've got $('div').replaceWith(error); // trying to replace the prev error } }); }); Anybody know how to this? Is this the best way to show only one error-message? Any help is highly appreciated.

  • How can I get read-ahead bytes?

    - by Bruno Martinez
    Operating systems read from disk more than what a program actually requests, because a program is likely to need nearby information in the future. In my application, when I fetch an item from disk, I would like to show an interval of information around the element. There's a trade off between how much information I request and show, and speed. However, since the OS already reads more than what I requested, accessing these bytes already in memory is free. What API can I use to find out what's in the OS caches? Alternatively, I could use memory mapped files. In that case, the problem reduces to finding out whether a page is swapped to disk or not. Can this be done in any common OS?

  • numpy.equal with string values

    - by Morgoth
    The numpy.equal function does not work if a list or array contains strings: >>> import numpy >>> index = numpy.equal([1,2,'a'],None) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: function not supported for these types, and can't coerce safely to supported types What is the easiest way to workaround this without looping through each element? In the end, I need index to contain a boolean array indicating which elements are None.

  • Text box added using javascript doesnot respond as expected to the js attached to it.

    - by Mallika Iyer
    Hello, I am adding a text box using javascript: This is what is generated: <dd id="text3-element" style="width: 350px;"> <input type="text" size="50" id="text3" name="text3" onblur="return getFieldValue(this.id);" value=""> </dd> This is what is present in the getFieldValue function: function getFieldValue(id){ var elem = document.getElementById(id); alert(elem.value); return false; } I'm trying to get the value of the field added using javascript when the value of the filed changes. However, I keep getting the value as 'undefined', in spite of entering text into the newly added text box. This does not happen if the form already has a text box to begin with - i.e., if a text box is not being added via a js function. Anything missing / look wrong here? Thanks!

  • Problem with assigning elements of a class array to individual variables in MATLAB

    - by Marc
    This is a bit of a duplicate of this question, this question, and this question, however those solutions don't work, so I'm asking mine. I've got an array of locally defined classes and I'd like to assign it to multiple, individual variables. This pattern doesn't work: %a is 2x1 of MyClass temp = mat2cell(a); [x,y] = temp{:}; %throws: ??? Insufficient number of outputs from right hand side of equal sign to satisfy assignment. Because temp is a single cell, with my 2x1 array in one cell, rather than a 2x1 cell array with one element of each of my original array in one cell. Any ideas?

  • custom validation does not seem to get registered.

    - by viet pham
    Hi, Inside a tab, I have a form that is dynamically loaded via ajax. Since the name of the field is dynamic too (e.g. ), I write a custom validation method inside the "on complete" like this. However, the custom code does not get executed (bolded alert never pops up) no matter what i try. $.ajax ( { url: 'index.php?func=trainingmgr&aAction=displayAddForm', type: 'GET', dataType: 'html', complete: function(req, err) { //Append response to the tab's body $(href, '#trainingTabs').append(req.responseText); $.validator.addMethod ( 'tRequired', function(value, element) { if(value == '') { **alert('I am empty');** return true; } else return false; }, '<br>Required field' ); $('#upload' + index).click ( function() { $('#addForm' + index).validate().numberOfInvalids(); } ); } } );

  • How does jQuery .data() work?

    - by kazanaki
    My Javascript knowledge is pretty limited. Instead of asking several javascript questions I got the "message" from Stack overflow and started using jQuery right away in order to save me some time. However several times I do not undestand the "magic" behind jQuery and I would love to learn the details. I want to use .data() in my application. The examples are very helpful. I do not understand however WHERE these values are stored. I inspect the webpage with Firebug and as soon as .data() saves an object to a dom element, I do not see any change in Firebug (either HTML or Dom tabs). I tried to look at jQuery source, but it is very advanced for my Javascript knowledge and I lost myself. So the question is: Where do the values stored by jQuery.data() actually go? Can I inspect/locate/list/debug them using a tool?

  • Problem understanding treesort in Haskell

    - by Jerry
    I am trying to figure out how exactly does treesort from here work (I understand flatten, insert and foldr). I suppose what's being done in treesort is applying insert for each element on the list thus generating a tree and then flattening it. The only problem I can't overcome here is where the list (that is the argument of the function) is hiding (because it is not written anywhere as an argument except for the function type declaration). One more thing: since dot operator is function composition, why is it an error when I change: treesort = flatten . foldr insert Leaf to treesort = flatten( foldr insert Leaf )?
