  • Jquery Double clicking on link removing div content

    - by ram
    I wrote this code to load the content of a DIV ,when some one clicks on a link. Now,if you click on a link twice,it is removing the content. Here is the code $('a').click(function() { var id = $(this).attr('class'); if(id == 'first') { $('.active').removeClass('active'); $('a.first').addClass('active'); } else if(id == 'second') { $('.active').removeClass('active'); $('a.second').addClass('active'); } $('#first').toggle(id == 'first'); $('#second').toggle(id == 'second'); });? <a class="first">one</a> <a class="second">two</a> <div> <li id="first"> <h2>pen</h2> <div> <div>parker</div> </div> </li> <li id="second" style="display: none;"> <h2>car</h2> <div>Bugatti</div> </div> </li> </div>? .active { color: green; }

  • Double reversals on technology decisions

    - by Kev
    Have you ever gone through a painful switch from one technology to another, only to switch back later in a project's lifetime? Was it because the technologies evolved differently than you expected, or because of something you didn't understand about them in the first place, or because they didn't fly when it came to beta testing or production? Did you regret the switch back too?

  • XCode Obj-C: Make new NSArray from one key each out of an Array of Dictionaries

    - by user323772
    This actually could be a multipart question. But here's the first part ... I have an array (actually in a plist) of dictionaries. Each dictionary has 3 keys in it: (title), (points), and (description). I am trying to make a NEW array with the values of the key "title" from each dictionary in that first array. Let me explain WHY I am doing this and maybe that will provide a better all around explanation. I am trying to let people pick from a pre-determined list. Heck, if this was a web page it would be very simple since all I really care about are the "points" and the "Title". On a web site I could simply do a drop down combo-box with the "points" being the value and the title being the text for each row. But this is not a web page. So what I am trying to do here is pop out a modal picker when they click the text field. The modal picker shows the alphabetical ordered "titles" from our new array. And whichever one they select, it closes the modal view and assigns that "title" text to the UITextField which cannot be edited by the user. I have some code to get my modal picker to pop out. But I need to feed it an array of just the "titles" of each dictionary in my real array. Thanks in advance (and yes I am a newbie)

  • Double use of variables?

    - by Vaccano
    I have read that a variable should never do more than one thing. Overloading a variable to do more than one thing is bad. Because of that I end up writing code like this: (With the customerFound variable) bool customerFound = false; Customer foundCustomer = null; if (currentCustomer.IsLoaded) { if (customerIDToFind = currentCustomer.ID) { foundCustomer = currentCustomer; customerFound = true; } } else { foreach (Customer customer in allCustomers) { if (customerIDToFind = customer.ID) { foundCustomer = customer; customerFound = true; } } } if (customerFound) { // Do something } But deep down inside, I sometimes want to write my code like this: (Without the foundCustomer variable) Customer foundCustomer = null; if (currentCustomer.IsLoaded) { if (customerIDToFind = currentCustomer.ID) { foundCustomer = currentCustomer; } } else { foreach (Customer customer in allCustomers) { if (customerIDToFind = customer.ID) { foundCustomer = customer; } } } if (foundCustomer != null) { // Do something } Does this secret desires make me an evil programmer? (i.e. is the second case really bad coding practice?)

  • Any way to define getters for lazy variables in Javascript arrays?

    - by LLer
    I'm trying to add elements to an array that are lazy-evaluated. This means that the value for them will not be calculated or known until they are accessed. This is like a previous question I asked but for objects. What I ended up doing for objects was Object.prototype.lazy = function(var_name, value_function) { this.__defineGetter__(var_name, function() { var saved_value = value_function(); this.__defineGetter__(var_name, function() { return saved_value; }); return saved_value; }); } lazy('exampleField', function() { // the code that returns the value I want }); But I haven't figured out a way to do it for real Arrays. Arrays don't have setters like that. You could push a function to an array, but you'd have to call it as a function for it to return the object you really want. What I'm doing right now is I created an object that I treat as an array. Object.prototype.lazy_push = function(value_function) { if(!this.length) this.length = 0; this.lazy(this.length++, value_function); } So what I want to know is, is there a way to do this while still doing it on an array and not a fake array?

  • Double Linked List header node keeps returning first value as 0

    - by Craig
    I will preface to say that this is my first question. I am currently getting my Masters degree in Information Security and I had to take C++ programming this semester. So this is homework related. I am not looking for you to answer my homework but I am running into a peculiar situation. I have created the program to work with a doubly linked list and everything works fine. However when I have the user create a list of values the first node keeps returning 0. I have tried finding some reading on this and I cannot locate any reference to it. My question is then is the header node(first node) always going to be zero? Or am I doing something wrong. case: 'C': cout<<"Please enter a list:"<<endl; while(n!=-999){ myList.insert(n); cin>> n;} break; I now enter: 12321, 1234,64564,346346. The results in 0, 12321, 1234, 64564,346346. Is this what should happen or am I doing something wrong? Also as this is my first post please feel free to criticize or teach me how to color code the keywords. Anyway this is a homework assignment so I am only looking for guidance and constructive criticism. Thank you all in advance So I cannot figure out the comment sections on this forum so I will edit the original post The first section is the constructor code: template <class Type> doublyLinkedList<Type>::doublyLinkedList() { first= NULL; last = NULL; count = 0; } Then there is my insert function : template <class Type> void doublyLinkedList<Type>::insert(const Type& insertItem) { nodeType<Type> *current; //pointer to traverse the list nodeType<Type> *trailCurrent; //pointer just before current nodeType<Type> *newNode; //pointer to create a node bool found; newNode = new nodeType<Type>; //create the node newNode->info = insertItem; //store the new item in the node newNode->next = NULL; newNode->back = NULL; if(first == NULL) //if the list is empty, newNode is //the only node { first = newNode; last = newNode; count++; } else { found = false; current = first; while (current != NULL && !found) //search the list if (current->info >= insertItem) found = true; else { trailCurrent = current; current = current->next; } if (current == first) //insert newNode before first { first->back = newNode; newNode->next = first; first = newNode; count++; } else { //insert newNode between trailCurrent and current if (current != NULL) { trailCurrent->next = newNode; newNode->back = trailCurrent; newNode->next = current; current->back = newNode; } else { trailCurrent->next = newNode; newNode->back = trailCurrent; last = newNode; } count++; }//end else }//end else }//end Then I have an initialization function too: template <class Type> void doublyLinkedList<Type>::initializeList() { destroy(); } Did I miss anything?

  • Dynamic added elements double effect after page transition

    - by Emil Moe
    I have added dynamic from jQuery in my code, but when I go back one page and return to the page where the 's are added and you press them, they somehow click twice now. I have tried with an alert('something'); when I click: $(document).on('click', '#products a', function() { alert('something'); } And it's shown twice when you return to the page. I have tried $('#products a').remove(); When you click the 'Back' button, because I thought all elements where added twice, but that made no difference. I don't have anything around these lines, maybe I need $(document).ready(); or something with pageinit?

  • Prevent double submission of forms in jQuery

    - by Adam
    I have an form that takes a little while for the server to process. I need to ensure that the user waits and does not attempt to resubmit the form by clicking the button again. I tried using the following jQuery code: <script type="text/javascript"> $(document).ready(function(){ $("form#my_form").submit(function(){ $('input').attr('disabled','disabled'); $('a').attr('disabled','disabled'); return true; }) }); </script> When I try this in Firefox everything gets disabled but the form is not submitted with any of the POST data it is supposed to include. I can't use jQuery to submit the form because I need the button to be submitted with the form as there are multiple submit buttons and I determine which was used by which one's value is included in the POST. I need the form to be submitted as it usually is and I need to disable everything right after that happens. Thanks!

  • ServiceLoader double iterator issues

    - by buge
    Is this a known issue? I had trouble finding any search results. When iterating over a ServiceLoader while an iteration already is in progress, the first iteration will be aborted. For example, assuming there are at least two implementations of Foo, the following code will fail with an AssertionError: ServiceLoader<Foo> loader = ServiceLoader.load(Foo.class); Iterator<Foo> iter1 = loader.iterator(); iter1.next(); Iterator<Foo> iter2 = loader.iterator(); while (iter2.hasNext()) { iter2.next(); } assert iter1.hasNext(); This only seems to occur, if the second iterator really terminates. The code will succeed in this variation for example: ServiceLoader<Foo> loader = ServiceLoader.load(Foo.class); Iterator<Foo> iter1 = loader.iterator(); iter1.next(); Iterator<Foo> iter2 = loader.iterator(); iter2.next(); assert iter1.hasNext(); Is this a bug or a feature? :p Is there a ticket for this already anywhere?

  • Active Directory Incorrect password attempts double counting

    - by Hidayath
    Hi I am using the following C# code to connect to active directory and validate the login, DirectoryEntry de = new DirectoryEntry(); string username = "myuser", path = "LDAP://addev2.dev.mycompany.com/CN=myuser,DC=dev,DC=mycompany,DC=com", password = "test"; for (int i = 0; i < 4;i++ ) { try { de.AuthenticationType = AuthenticationTypes.Sealing | AuthenticationTypes.Secure | AuthenticationTypes.FastBind; de.Username = username; de.Password = password; de.Path = path; //de.RefreshCache(); Object obj = de.NativeObject; } catch (Exception ex) { Console.WriteLine(ex.Message); } this works fine when the password is correct. However when the password is incorrect this shows as 2 invalid attempts in AD. So what happens is when the AD admin allows 5 invalid attempts the user is locked out on the 3rd attempt. when i look in the AD's event log 1 see 2 entries. 1)Pre-authentication failed: 2)Logon attempt by: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0 Logon account: [email protected] Source Workstation: WKSXXXX Error Code: 0xC000006A Stepping thro the code i see 2 event entries on the line de.RefreshCache() I tried using de.NativeObject to see if that would solve the problem. No Dice Anyone have any pointers?

  • PHP: Check if 0?

    - by tarnfeld
    Hi, I am using a class which returns me the value of a particular row and cell of an excel spreadsheet. To build up an array of one column I am counting the rows and then looping through that number with a for() loop and then using the $array[] = $value to set the incrementing array object's value. This works great if none of the values in a cell are 0. The class returns me a number 0 so it's nothing to do with the class, I think it's the way I am looping through the rows and then assigning them to the array... I want to carry through the 0 value because I am creating graphs with the data afterwards, here is the code I have. // Get Rainfall $rainfall = array(); for($i=1;$i<=$count;$i++) { if($data->val($i,2) != 'Rainfall') // Check if not the column title { $rainfall[] = $data->val($i,2); } } For your info $data is the excel spreadsheet object and the method $data->val(row,col) is what returns me the value. In this case I am getting data from column 2. Screenshot of spreadsheet http://cl.ly/1Dmy Thanks! All help is very much appreciated!

  • how can I get around no arrays as class constants in php?

    - by user151841
    I have a class with a static method. There is an array to check that a string argument passed is a member of a set. But, with the static method, I can't reference the class property in an uninstantiated class, nor can I have an array as a class constant. I suppose I could hard code the array in the static method, but then if I need to change it, I'd have to remember to change it in two places. I'd like to avoid this.

  • Can this be done in 1 line? [PHP]

    - by Angelo
    Can this be done in 1 line with PHP? Would be awesome if it could: $out = array("foo","bar"); echo $out[0]; Something such as: echo array("foo","bar")[0]; Unfortunately that's not possible. Would it be possible like this? So I can do this for example in 1 line: echo array(rand(1,100), rand(1000,2000))[rand(0,1)];

  • Simple php if query to double check

    - by skarama
    Is anything wrong with this code? <?php $variable = ; if (isset($variable)) { echo $variable ; echo "also this" ; } else echo "The variable is not set" ; ?> also, the other potential value of the variable is : $variable = <a href="http://www.mysite.com/article">This Article</a>; To clarify, I have a variable that may hold one of two possible values : an a href tag with it's url, or notihng at all. I need to have two different printouts for each of these cases, maybe I'm not doing it the right way though!

  • PHP: Need a double check on an error in this small code

    - by Josh K
    I have this simple Select box that is suppose to store the selected value in a hidden input, which can then be used for POST (I am doing it this way to use data from disabled drop down menus) <body> <?php $Z = $_POST[hdn]; ?> <form id="form1" name="form1" method="post" action="test.php"> <select name="whatever" id="whatever" onchange="document.getElementById('hdn').value = this.value"> <option value="1">1Value</option> <option value="2">2Value</option> <option value="3">3Value</option> <option value="4">4Value</option> </select> <input type="hidden" name ='hdn' id="hdn" /> <input type="submit" id='submit' /> <?php echo "<p>".$Z."</p>"; ?> </form> </body> The echo call works for the last 3 options (2,3,4) but if I select the first one it doesnt output anything, and even if i change first one it still doesnt output anything. Can someone explain to me whats going on, I think it might be a syntax issue.

  • Reading variable with double float precision from a text file with gnuplot

    - by user3636322
    I have a text file, containing data in 3 columns like below: 0.0100000000 | 0.0058077299 | -0.0000000288 0.0110000000 | 0.0075128707 | -0.0000000373 0.0120000000 | 0.0093579693 | -0.0000000465 I want to get the variables from this file in gnuplot and use them to draw graphs: What I exactly do is like below (e.g: to pick the variable from row 2 column 3): ii= 2 a_0 = system("awk '{ if (NR == " . ii . ") printf \"%f\", $3}' " .datafile) a_0 = a_0+0. but what is written as a_0 is zero! How can I increase the precision to get the exact value?

  • JavaScript two-dimensional Array to PHP

    - by vi
    Hi I have to send a two-dimensional JavaScript Array to a PHP page. Indeed, I'm working on a form-builder, in which the user can add or remove fields. These fields are added (or removed) using JavaScript (jQuery). When the user is done and hit a 'publish' button, I have to get all the fields concerned and send them to a PHP page which would build a real form with it. I found a way to do it but I'm pretty sure it's not very clean : addedFields = new Array(); $("#add-info .field").each(function() { addedFields.push(new Array($(this).find('.name').val(), $(this).find('.type').val(), $(this).find('.size').val())); }); Basically, the ".field" class objects are <tr> and the ".name", ".type" and ".size" objects are inputs. So I get an array of [name, type, size], then I convert it into a string using addedFields = addedFields.join(";"); Finally, I go to the PHP form that way ; document.location.href = "create.php?addedfields=" + addedFields; Concerning the PHP code, I create a PHP array using the explode() function: $addedFields = explode(";", $_GET['addedfields']); and then I use it again for each element in the array: foreach ($addedFields as $field) { $field = explode(",", $field); echo "<li>Field with name : '$field[0]', of '$field[1]' type and with a size of $field[2]"; }

  • Binding a single array cell to a WPF control

    - by yomi
    Hi, I have a bool array of size 4 and I want to bind each cell to a different control. This bool array represents 4 statuses (false = failure, true = success). This bool array is a propery with a class: class foo : INotifyPropertyChanged { ... private bool[] _Statuses; public bool[] Statuses { get {return Statuses;} set { Statuses = value; OnPropertyChanged("Statuses"); } } In XAML there are 4 controls, each one bound to one cell of the array: ... Text="{Binding Path=Statuses[0]}" ... ... Text="{Binding Path=Statuses[1]}" ... ... Text="{Binding Path=Statuses[2]}" ... ... Text="{Binding Path=Statuses[3]}" ... The problem is that the notify event is raised only when I change the array itself and isn't raised when I change one value within the array, i.e, next code line raises the event: Statuses = new bool[4]; but next line does not raises the event: Statuses [0] = true; How can I raise the event each time one cell is changed?
