  • Jquery, how to escape quotes

    - by Sandro Antonucci
    I'm using a simple jquery code that grabs html code form a tag and then puts this content into a form input <td class="name_cat" ><span class="name_cat">It&#039;s a &quot;test&quot; </span> (5)</td> jquery gets the content into span.name_catand returns it as It's a "test". So when I print this into an input it becomes <input value="It's a "test"" /> which as you can imagine will only show as It's a , the following double quote will close the value tag. What's the trick here to keep the original string while not showing utf8 code in the input? Jquery code $(".edit_cat").click(function(){ tr = $(this).parents("tr:first"); id_cat = $(this).attr("id"); td_name = tr.find(".name_cat"); span_name = tr.find("span.name_cat").html(); form = '<form action="/admin/controllers/edit_cat.php" method="post" >'+ '<input type="hidden" name="id_cat" value="'+id_cat+'" />'+ '<input type="text" name="name_cat" value="'+span_name+'" />'+ '<input type="submit" value="save" />'+ '</form>'; td_name.html(form); console.log(span_name); } ); I basically need html() not to decode Utf8

  • how can I store the current status of the game in cocos2d ?

    - by srikanth rongali
    I am writing a shooting game in cocos2d. And each enemy enters the screen after the current one is dead. I have stores the enemies and their properties in plist. I need to save the current state of the game. If any phone call comes the game should be started from the current state. So, I usedNsUserDefaults in this way, - (void) applicationDidFinishLaunching:(UIApplication*)application { ... NSUserDefaults *myDefaultOptions = [[myDefaultOptions stringForKey:@"enemyNumber"]intValue] ; //tempCount4 is the current Enemy number. It was declared in another class. I am using extern and using the value here. tempCount4 = [[myDefaultOptions stringForKey:@"enemyNumber"]intValue] ; } - (void)applicationWillTerminate:(UIApplication *)application { [[CCDirector sharedDirector] end]; [myDefaultOptions setObject:tempCount4 forKey:@"enemyNumber"]; } The control is not entering in to the (void)applicationWillTerminate:(UIApplication *)application when I pressed the Home button. And when I touched the game icon on the screen the game is running from first screen and in log (terminal )it is not showing any values. And what should I store to resume my game from stored state. Can you explain where I was wrong ? Thank You.

  • Checkbox not checkable in dialog ui

    - by Sable Foste
    I am trying to solve a z-index problem with the jQuery UI Dialog, similar to question Can't select or deselect checkboxes inside jQuery UI Modal Dialog , knowing there is a bug report out there. So in trying to up the z-index as recommended, I added the following code: $('#interface').click(function(evform){ $('#interface').prop('z-index')=99999; }); where the chrome and firefox console.log states: Uncaught ReferenceError: Invalid left-hand side in assignment HOWEVER, despite the error, the checkbox now works (throwing the console error every time). If I remove the offending line, the checkbox becomes "unclickable". How can I properly code this? My HTML: <div id="dialog" title="Loading..."> <p id="interface">Loading...</p> </div> (by the way, I tried adding inline style to the <p>, and it didn't work: <p id="interface" style="z-index:99999">Loading...</p> And with AJAX, I replace the contents of '#interface' with valid checkbox html such as: <label for="right"> <input name="right" type="checkbox"> </label> and I have the usual jQuery/Dialog UI files included. One final note, I tried to get creative, since this wasn't working and manually switch the checkbox by: if ($(evform.target).prop('type')=="checkbox"){ $(evform.target).checked; } Thank you to anyone willing to help me figure this out!

  • Selenium problem locating by DOM

    - by bartonlee
    Hi, I'm trying to use the DOM to locate a form element in Selenium but I can't get it to work. Even if I use the example in the Selenium documentation it still fails, for example with this html... <html> <body> <form id="loginForm"> <input name="username" type="text" /> <input name="password" type="password" /> <input name="continue" type="submit" value="Login" /> <input name="continue" type="button" value="Clear" /> </form> </body> <html> and this command in the Selenium IDE... verifyElementPresent with target... dom=document.forms['loginForm'] I get [error] false in the log. The 'getElementById' example in the documentation does work, but none of the others. Can someone explain what I'm doing wrong here? Thanks.

  • What is common between environments within a shell terminal session?

    - by Matt1776
    I have a custom shell script that runs each time a user logs in or identity is assumed, its been placed in /etc/profile.d and performs some basic env variable operations. Recently I added some code so that if screen is running it will reattach it without needing me to type anything. There are some problems however. If I log-in as root, and su - to another user, the code runs a second time. Is there a variable I can set when the code runs the first time that will prevent a second run of the code? I thought to write something to the disk but then I dont want to prevent the code from running if I begin a new terminal session. Here is the code in question. It first attempts to reattach - if unsuccessful because its already attached (as it might be on an interruped session) it will 'take' the session back. screen -r if [ -z "$STY" ]; then exec screen -dR fi Ultimately this bug prevents me from substituting user to another user because as soon as I do so, it grabs the screen session and puts me right back where I started. Pretty frustrating

  • How to structure code with 2 methods, one after another, which throw the same two exceptions?

    - by dotnetdev
    Hi, I have two methods, one called straight after another, which both throw the exact same 2 exceptions (IF an erroneous condition occurs, not stating that I'm getting exceptions). For this, should I write seperate try and catch blocks with the one statement in each try block and catch both exceptions (Both of which I can handle as I checked MSDN class library reference and there is something I can do, eg, re-open SqlConnection or run a query and not a stored proc which does not exist). So code like this: try { obj.Open(); } catch (SqlException) { // Take action here. } catch (InvalidOperationException) { // Take action here. } And likewise for the other method I call straight after. This seems like a very messy way of coding. The other way is to code with the exception variable (that is ommited as I am using AOP to log the exception details, using a class-level attribute). Doing this, this could aid me in finding out which method caused an exception and then taking action accordingly. Is this the best approach or is there another best practise altogether? I also assume that, as only these two methods are thrown, I do not need to catch Exception as that would be for an exception I cannot handle (causes way out of my control). Thanks

    - by user556167
    Hi all. I am writing an app to share a page to friends when browsing. To this end, I can get the url of the page to my app and display it on the screen. Could anyone tell me, how to improve this, to show the headline of the page and the picture of a page as it appears when a page is being shared to friends on facebook. Here is the code to get and display the url of the page: Intent intent = getIntent(); String action = intent.getAction(); String type = intent.getType(); String mNewLinkUrl=""; if (action != null && type != null && Intent.ACTION_SEND.equals(action) && "text/plain".equals(type)){ mNewLinkUrl = intent.getStringExtra(Intent.EXTRA_TEXT); } TextView ptext = (TextView) findViewById(R.id.pagetext); ptext.append("\n"+mNewLinkUrl); Any insight will be appreciated. //update 1 found a method: use Jsoup to download the html as a Document.

  • Display web page from another site in asp page.

    - by Daniel
    hi all, Our customer has a requirement to extend the functionality of their existing large government project. It is an ASP.NET 3.5 (recently upgraded from 2.0) project. The existing solution is quite a behemoth that is almost unmaintainable so they have decided that they want to provide the new functionality by hosting it on another website that is shown within the existing website. As to how this is best to be done I'm not quite sure right now and if there is any security issues preventing it or that need to be considered. Essentially the user would log on to the existing web site as normal and when cliicking on a certain link the page would load as normal with some kind of frame or control that has within it the contents of the page from the other site. IE. They do not want to simply redirect to the other site they want to show it embedded within the current one such that the existing menus etc are still available. I believe if information needed to be passed to the embedded page it would be done using query strings as I'm not sure if there is even another way to accomplish this. Can anyone give me some pointers on where to start at looking to implement this or any potential pitfalls I should be aware of. Thanks

  • File uploads simply do not work - what could be wrong server side?

    - by vanneto
    This has been grinding my gears for at least a week now. I have a site which has a crucial function - the upload component. Without it, the site is completely useless. Now, lots of users have problems uploading files. This is why I implemented a log system that keeps track of what happens when the file is on the server. Problem is, only a minority of problems happen when the file is on the server, the problems happen client side. For example, when I tried SWFUpload the errors where 'I/O Error'. When I changed to Uploadify I get 'HTTP Error'. I am trying to get a more detailed error description as I type this. I am starting to think its not the client or the upload software, but the server. What could be wrong? The following directives for PHP are set: upload_max_filesize 200M post_max_size 200M memory_limit 256M max_execution_time 4200 max_input_time 4200 I simply have no clue why file uploads are failing. They should not fail. I would really appreciate any answers as why the uploads could be failing. Thank you.

  • Concatenate an each loop inside another

    - by Lothar
    I want to to concatenate the results of a jquery each loop inside of another but am not getting the results I expect. $.each(data, function () { counter++; var i = 0; var singlebar; var that = this; tableRow = '<tr>' + '<td>' + this.foo + '</td>' + $.each(this.bar, function(){ singlebar = '<td>' + that.bar[i].baz + '</td>'; tableRow + singlebar; }); '</tr>'; return tableRow; }); The portion inside the nested each does not get added to the string that is returned. I can console.log(singlebar) and get the expected results in the console but I cannot concatenate those results inside the primary each loop. I have also tried: $.each(this.bar, function(){ tableRow += '<td>' + that.bar[i].baz + '</td>'; }); Which also does not add the desired content. How do I iterate over this nested data and add it in the midst of the table that the primary each statement is building?

  • Two references to the same domain/entity model

    - by Sbossb
    Problem I want to save the attributes of a model that have changed when a user edits them. Here's what I want to do ... Retrieve edited view model Get domain model and map back updated value Call the update method on repository Get the "old" domain model and compare values of the fields Store the changed values (in JSON) into a table However I am having trouble with step number 4. It seems that the Entity Framework doesn't want to hit the database again to get the model with the old values. It just returns the same entity I have. Attempted Solutions I have tried using the Find() and the SingleOrDefault() methods, but they just return the model I currently have. Example Code private string ArchiveChanges(T updatedEntity) { //Here is the problem! //oldEntity is the same as updatedEntity T oldEntity = DbSet.SingleOrDefault(x => x.ID == updatedEntity.ID); Dictionary<string, object> changed = new Dictionary<string, object>(); foreach (var propertyInfo in typeof(T).GetProperties()) { var property = typeof(T).GetProperty(propertyInfo.Name); //Get the old value and the new value from the models var newValue = property.GetValue(updatedEntity, null); var oldValue = property.GetValue(oldEntity, null); //Check to see if the values are equal if (!object.Equals(newValue, oldValue)) { //Values have changed ... log it changed.Add(propertyInfo.Name, newValue); } } var ser = new System.Web.Script.Serialization.JavaScriptSerializer(); return ser.Serialize(changed); } public override void Update(T entityToUpdate) { //Do something with this string json = ArchiveChanges(entityToUpdate); entityToUpdate.AuditInfo.Updated = DateTime.Now; entityToUpdate.AuditInfo.UpdatedBy = Thread.CurrentPrincipal.Identity.Name; base.Update(entityToUpdate); }

  • Adobe Air, packaged install fails with my trace routine... how come?

    I cobbled together some code from here and there for a trace I like... it generates an error to get a stack trace and picks out the traced routine name, I like that detail in the trace log. Problem: it fails in an installed AIR file. I wonder why? I don't expect it to do anything as is... just, I'd prefer it not cause the program to fail! tx artie enter code here static public function XTRACE( ... traceArgs ):void { try { throw new Error(); // make a stack } catch (e:Error) { var stack:String = e.getStackTrace(); var frames:Array = stack.split("\n"); var myFrame:String = String(frames[2]); myFrame = myFrame.replace("\t", ""); // "at " can be followed by some part of the package // you don't want to see.

  • Database solution for 200million writes/day, monthly summarization queries

    - by sb
    Hello. I'm looking for help deciding on which database system to use. (I've been googling and reading for the past few hours; it now seems worthwhile to ask for help from someone with firsthand knowledge.) I need to log around 200 million rows (or more) per 8 hour workday to a database, then perform weekly/monthly/yearly summary queries on that data. The summary queries would be for collecting data for things like billing statements, eg. "How many transactions of type A did each user run this month?" (could be more complex, but that's the general idea). I can spread the database amongst several machines, as necessary, but I don't think I can take old data offline. I'll definitely need to be able to query a month's worth of data, maybe a year. These queries would be for my own use, and wouldn't need to be generated in real-time for an end-user (they could run overnight, if needed). Does anyone have any suggestions as to which databases would be a good fit? P.S. Cassandra looks like it would have no problem handling the writes, but what about the huge monthly table scans? Is anyone familiar with Cassandra/Hadoop MapReduce performance?

  • Listing all objects that share a common variable in Javascript

    - by ntgCleaner
    I'm not exactly sure how to ask this because I am just learning OOP in Javascript, but here it goes: I am trying to be able to make a call (eventually be able to sort) for all objects with the same variable. Here's an example below: function animal(name, numLegs, option2, option3){ this.name = name; this.numLegs = numLegs; this.option2 = option2; this.option3 = option3; } var human = new animal(Human, 2, example1, example2); var horse = new animal(Horse, 4, example1, example2); var dog = new animal(Dog, 4, example1, example2); Using this example, I would like to be able to do a console.log() and show all animal NAMES that have 4 legs. (Should only show Horse and Dog, of course...) I eventually want to be able to make a drop-down list or a filtered search list with this information. I would do this with php and mySQL but I'm doing this for the sake of learning OOP in javascript. I only ask here because I don't exactly know what to ask. Thank you!

  • Variable won't store in session

    - by Mittens
    So I'm trying to store the "rank" of a user when they log in to a control panel which displays different options depending on the given rank. I used the same method as I did for storing and displaying the username, which is displayed on the top of each page and works just fine. I can't for the life of me figure out why it won't work for the rank value, but I do know that it is not saving it in the session. Here is the bit that's not working; $username = ($_POST['username']); $password = hash('sha512', $_POST['password']); $dbhost = 'mysql:host=¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦;dbname=¦¦¦¦¦¦¦¦¦¦¦'; $dbuser = '¦¦¦¦¦¦¦¦¦¦¦'; $dbpassword = '¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦'; try { $db = new PDO($dbhost, $dbuser, $dbpassword); $statement = $db->prepare("select password from users where email = :name"); $statement->execute(array(':name' => $username)); $result = $statement->fetch(); $pass = $result[password]; $rank = $result[rank];} catch(PDOException $e) {echo $e->getMessage();} if ($password == $pass) { session_start(); $_SESSION['username'] = $username; $_SESSION['rank'] = $rank; header('Location: http://¦¦¦¦¦¦¦¦¦.ca/manage.php'); } else{ include'../../includes/head.inc'; echo '<h1>Incorrect username or password.</h1>'; include'../../includes/footer.inc'; } I'm also new to the whole PDO thing, hence why my method of authenticating the password is pretty sketchy.

  • Iterate over defined elements of a JS array

    - by sibidiba
    I'm using a JS array to Map IDs to actual elements, i.e. a key-value store. I would like to iterate over all elements. I tried several methods, but all have its caveats: for (var item in map) {...} Does iterates over all properties of the array, therefore it will include also functions and extensions to Array.prototype. For example someone dropping in the Prototype library in the future will brake existing code. var length = map.lenth; for (var i = 0; i < length; i++) { var item = map[i]; ... } does work but just like $.each(map, function(index, item) {...}); They iterate over the whole range of indexes 0..max(id) which has horrible drawbacks: var x = []; x[1]=1; x[10]=10; $.each(x, function(i,v) {console.log(i+": "+v);}); 0: undefined 1: 1 2: undefined 3: undefined 4: undefined 5: undefined 6: undefined 7: undefined 8: undefined 9: undefined 10: 10 Of course my IDs wont resemble a continuous sequence either. Moreover there can be huge gaps between them so skipping undefined in the latter case is unacceptable for performance reasons. How is it possible to safely iterate over only the defined elements of an array (in a way that works in all browsers and IE)?

  • Thread-Safe lazy instantiating using MEF

    - by Xaqron
    // Member Variable private static readonly object _syncLock = new object(); // Now inside a static method foreach (var lazyObject in plugins) { if ((string)lazyObject.Metadata["key"] = "something") { lock (_syncLock) { // It seems the `IsValueCreated` is not up-to-date if (!lazyObject.IsValueCreated) lazyObject.value.DoSomething(); } return lazyObject.value; } } Here I need synchronized access per loop. There are many threads iterating this loop and based on the key they are looking for, a lazy instance is created and returned. lazyObject should not be created more that one time. Although Lazy class is for doing so and despite of the used lock, under high threading I have more than one instance created (I track this with a Interlocked.Increment on a volatile static int and log it somewhere). The problem is I don't have access to definition of Lazy and MEF defines how the Lazy class create objects. I should notice the CompositionContainer has a thread-safe option in constructor which is already used. My questions: 1) Why the lock doesn't work ? 2) Should I use an array of locks instead of one lock for performance improvement ?

  • Django - Weird behaviour of sessions variables with Apache

    - by Étienne Loks
    In a Menu class with Section children, each Section has an available attribute. This attribute is initialized during the instance creation. The process of getting the availability is not trivial, so I stock a Menu instance for each user in a session variable. With the Django embedded webserver this works well. But when I deploy the application on an Apache webserver I can observe a very weird behavior. Once authentified, a click on a link or a refreshment of the page and the availability of each Section seems to be forgotten (empty menu but in the log file I can see that all Sections are here) then a new refresh on the page the availability is back, a new refresh the menu disappears once again, etc. There is no cache activated on the web server. The menu is initialized in a context processor. def get_base_context(request): if 'MENU' not in request.session or \ not request.session['MENU'].childs or\ request.session['MENU'].user != request.user: _menu = Menu(request.user) _menu.init() request.session['MENU'] = _menu (...) I have no idea what could cause such a behavior. Any clue?

  • Method invoked but not returning anything

    - by or azran
    i am calling this method from a touch in UITableViewCell , -(void)PassTitleandiMageByindex:(NSString *)number{ NSLog(@"index : %d",number.intValue); NSArray *objectsinDictionary = [[[NSArray alloc]init]autorelease]; objectsinDictionary = [[DataManeger sharedInstance].sortedArray objectAtIndex:number.intValue]; if ([objectsinDictionary count] > 3) { ProductLabel = [objectsinDictionary objectAtIndex:3]; globaliMageRef = [objectsinDictionary objectAtIndex:2]; [self performSegueWithIdentifier:@"infoseg" sender:self]; }else{ mQid = [objectsinDictionary objectAtIndex:1]; globaliMageRef = [objectsinDictionary objectAtIndex:2]; [mIQEngines Result:mQid]; NSLog(@"mQid : %@ Global : %@",mQid,globaliMageRef); }} Problem:- i am trying to get the same functionality programmatically by calling [self PassTitleandiMageByindex:stringNumber]; when i am calling this programmatically i can see the debug log getting in the place it should be, but nothing happens (by pressing the UITableViewCellon the screen) here is how it turns on by touch, - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{ [tableView deselectRowAtIndexPath:indexPath animated:YES]; NSString *st = [NSString stringWithFormat:@"%d",[indexPath row]]; [self PassTitleandiMageByindex:st];} I have also tried to call the table-view delegate by :[[Tview delegate] tableView:Tview didSelectRowAtIndexPath:selectedCellIndexPath]; but, nothing happened.

  • 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?
