  • Remove the period and everything after it using jQuery

    - by veryserious
    Is there a way to remove the period and everything after it using jQuery? The numbers following the period vary in length, so it's not as simple as finding the length. For example: <span class="changethis">505.234</span> <span class="changethis">23.93</span> Thanks for your help! P.S. (bonus) If there is a way to round up if it's x.5 or higher that would be awesome. Not essential though.

  • Why doesn't the C++ default destructor destroy my objects?

    - by Oszkar
    The C++ specification says the default destructor deletes all non-static members. Nevertheless, I can't manage to achieve that. I have this: class N { public: ~N() { std::cout << "Destroying object of type N"; } }; class M { public: M() { n = new N; } // ~M() { //this should happen by default // delete n; // } private: N* n; }; Then this should print the given message, but it doesn't: M* m = new M(); delete m; //this should invoke the default destructor

  • Getting imagename and make link from <img> with jQuery

    - by Bulan
    With jQuery, I want to make all images under a specific path on a site clickable and showing a big image using Fancybox, which is a lighbox variant plugin for jQuery. My small images are located under "images/products/small", the big ones under "images/products/big" and the imagename is always the same The page is showing the image with the following code: <img src="images/products/small/hat.jpg" alt="Nice hat"> What i want is some jQuery script that makes this into: <a href="images/products/big/hat.jpg" class="fancybox"><img src="images/products/small/hat.jpg" alt="Nice hat"></a> Maybe the part with setting class on the link tag can be skipped and just activate fancybox on the element directly with $(elm).fancybox(); I was looking around a bit and it looks like the jQuery functions "attr" and "wrap" might be useful, but with my currently limited jQuery skills I can't really connect the dots.

  • Mootools event leak

    - by user572263
    The example to demonstrate the issue can be found here: link text The test shows a basic Mootools class that contains an element variable with a click event attached. There’s also a “cleanup” function to remove the event and nullify the element variable. My problem is that when I loop a thousand times to create the “LeakClass” instance and clean it up, it causes a major memory leak like there’s no tomorrow. I tested this on IE8 and Chrome. On the other hand what I’ve noticed is that if I comment out the line that adds the “click” event, the code doesn’t leak. Can somebody please help me structure the class/event in a manner that it doesn’t leak. Thanks in advance.

  • NUnit [Test] is not a valid attribute

    - by tyndall
    I've included the necessary assemblies into a Windows Class project in VS2008. When I start to try to write a test I get a red squiggle line and the message [Test] is not a valid attribute. I've used NUnit before... maybe an earlier version. What am I doing wrong? I'm on version 2.5.2. using System; using System.Collections.Generic; using System.Linq; using System.Text; using NUnit; using NUnit.Core; using NUnit.Framework; namespace AccessPoint.Web.Test { public class LoginTests { [Test] public void CanLogin() { } } }

  • How can data not stored in a DB be accessed from any activity in Android?

    - by jul
    hi, I'm passing data to a ListView to display some restaurant names. Now when clicking on an item I'd like to start another activity to display more restaurant data. I'm not sure about how to do it. Shall I pass all the restaurant data in a bundle through the intent object? Or shall I just pass the restaurant id and get the data in the other activity? In that case, how can I access my restaurantList from the other activity? In any case, how can I get data from the restaurant I clicked on (the view only contains the name)? Any help, pointers welcome! Thanks Jul ListView lv= (ListView)findViewById(R.id.listview); lv.setAdapter( new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,restaurantList.getRestaurantNames())); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Intent i = new Intent(Atable.this, RestaurantEdit.class); Bundle b = new Bundle(); //b.putInt("id", ? ); startActivityForResult(i, ACTIVITY_EDIT); } }); RestaurantList.java package org.digitalfarm.atable; import java.util.ArrayList; import java.util.List; public class RestaurantList { private List<Restaurant> restaurants = new ArrayList<Restaurant>(); public List<Restaurant> getRestaurants() { return this.restaurants; } public void setRestaurants(List<Restaurant> restaurants) { this.restaurants = restaurants; } public List<String> getRestaurantNames() { List<String> restaurantNames = new ArrayList<String>(); for (int i=0; i<this.restaurants.size(); i++) { restaurantNames.add(this.restaurants.get(i).getName()); } return restaurantNames; } } Restaurant.java package org.digitalfarm.atable; public class Restaurant { private int id; private String name; private float latitude; private float longitude; public int getId() { return this.id; } public void setId(int id) { this.id = id; } public String getName() { return this.name; } public void setName(String name) { this.name = name; } public float getLatitude() { return this.latitude; } public void setLatitude(float latitude) { this.latitude = latitude; } public float getLongitude() { return this.longitude; } public void setLongitude(float longitude) { this.longitude = longitude; } }

  • jQuery reference to (this) does not work?

    - by FFish
    I have this href link with text either "attivo" or "non attivo" User can set the item to 'active' or 'closed' in the database with an ajax request $.post() I have 2 questions for these: I can't get the reference to $(this) to work.. I tried it with a normal link and it works, but not wrapped in if/else?? How can I prevent the user from clicking more than one time on the link and submitting several request? Is this a valid concern? Do I need some sort of a small timer or something? First I was thinking about a javascript confirm message, but that's pretty annoying for this function.. HTML: <dl id='album-list'> <dt id="dt-2">some title</dt> <dd id="dd-2"> some description<br /> <div class='links-right'>status: <a class='toggle-active' href='#'>non attivo</a></div> </dd> </dl> <a class="test" href="#">test</a> JS: $('dd a.toggle-active').click(function() { var a_ref = $(this); var id = a_ref.parent().parent().attr('id').substring(3); if (a_ref.text() == "non attivo") { var new_active = "active"; // for db in english $.post("ajax-aa.php", {album_id:id, album_active:new_active}, function(data) { // alert("success"); a_ref.text("non attivo"); // change href text }); } else { var new_active = "closed"; // for db in english $.post("ajax-aa.php", {album_id:id, album_active:new_active}, function(data) { // alert("success"); a_ref.text("attivo"); // change href text }); } return false; }); $('a.test').click(function() { var a_ref = $(this); $.post("ajax-aa.php", {album_id:2, album_active:"active"}, function(data) { a_ref.text("changed"); }); return false; })

  • Is there a way to set a DLL to always follow CultureInfo.InvariantCulture by default, if not specifi

    - by JL
    I have a lot of code in a class library that does not specify CultureInfo.InvariantCulture. For example in toString operations, toBool, toInt, etc. Is there a way I can get set a property for the class library to always execute using CultureInfo.InvariantCulture, even if it is not explicitly specified everywhere in the code? Sort of like a global switch? It is not only messy to have to explicitly type it everytime, it makes my code less readable, and is a royal pain for example: if (Convert.ToInt16(task.RetryCount, CultureInfo.InvariantCulture) < Convert.ToInt16(ConfigurationManager.AppSettings["TasksMaxRetry"], CultureInfo.InvariantCulture))

  • How to get the Primary/Secondary color in jQuery UI Theme

    - by simonsanderson
    Is there a way to reference the colours used in the jQuery themes without creating a simple style for each theme that I may choose to use? Example: I have some text as follows <div>Hello</div> which I'd like to be change colour in line with my theme of the day. I wish to use the primary colour from a theme (say ui-lightness) which is "#1c94c4" as defined in several of the styles such as ui-state-default in ui-lightness.css The problem is that if I do the following <div class='ui-state-default'>Hello</div> I get all the other style effects, like borders and background colour, which are not right for my application What I'd like to do is something like <div class='ui-primary-color'>Hello</div> which would automatically change only the colour dependent on the theme. PS. Doing a pre-build pre-processing step to parse the themes and generate a customised css style would be my least favourable option here!

  • Adding Related Entities without using navigation properties

    - by Barisa Puter
    I have the following classes, set for testing: public class Company { [DatabaseGenerated(DatabaseGeneratedOption.Identity)] public int Id { get; set; } public string Name { get; set; } } public class Employee { [DatabaseGenerated(DatabaseGeneratedOption.Identity)] public int Id { get; set; } public string Name { get; set; } public int CompanyId { get; set; } public virtual Company Company { get; set; } } public class EFTestDbContext : DbContext { public DbSet<Employee> Employees { get; set; } public DbSet<Company> Companies { get; set; } } For the sake of testing, I wanted to insert one company and one employee for that company with single SaveChanges call, like this: Company company = new Company { Name = "Sample company" }; context.Companies.Add(company); // ** UNCOMMENTED FOR TEST 2 //Company company2 = new Company //{ // Name = "Some other company" //}; //context.Companies.Add(company2); Employee employee = new Employee { Name = "Hans", CompanyId = company.Id }; context.Employees.Add(employee); context.SaveChanges(); Even though I am not using navigational properties, but instead I've made relation over Id, this somehow mysteriously worked - employee was saved with proper foreign key to company which got updated from 0 to real value, which made me go ?!?! Some hidden C# feature? Then I've decided to add more code, which is commented in the snippet above, making it to be inserting of 2 x Company entity and 1 x Employee entity, and then I got exception: Unable to determine the principal end of the 'CodeLab.EFTest.Employee_Company' relationship. Multiple added entities may have the same primary key. Does this mean that in cases where foreign key is 0, and there is a single matching entity being inserted in same SaveChanges transaction, Entity Framework will assume that foreign key should be for that matching entity? In second test, when there are two entities matching the relation type, Entity Framework throws an exception as it is not able to figure out to which of the Companies Employee should be related to.

  • Is it possible to append html code in parts via JQuery?

    - by phpheini
    I am trying to append li elements coming from a php file with JQuery. Problem is that the html code needs to be seperately appended to different html IDs according to the key value. Unfortunately as I understood append() can only append correct html with all elements closed. Otherwise it will automatically close the tags. The following code will NOT work as dval contains code like <div><li class="some">Some value</li> and append() will make <div><li class="some">Some value</li></div> out of it. So I was wondering whether there is another way, maybe a function other than append() to be able to append html parts? $.each(obj, function(key,val) { $.each(obj[key], function(key, dval) { if(key == "text") { $("#" + key).append(dval); } }) });

  • Is it possible for a parent to use a child's constant or static variables from inside a static metho

    - by ryeguy
    Below is an example of what I'm trying to do. The parent can't access any of the child's variables. It doesn't matter what technique I use (static or constants), I just need some kind of functionality like this. class ParentClass { public static function staticFunc() { //both of these will throw a (static|const) not defined error echo self::$myStatic; echo self::MY_CONSTANT; } } class ChildClass extends ParentClass { const MY_CONSTANT = 1; public static $myStatic = 2; } ChildClass::staticFunc();

  • Is it possible to use AutoMapper to map methods?

    - by Woj
    I have two classes: public class TestClass1 { public int TestInt { get; set; } public void TestMethod() { // Do something } } public class TestClass2 { public int TestInt { get; set; } public void TestMethod() { // Do something } } I want to create interface that I can use for both classes. The easiest solution is to implement the interface on TestClass1 and TestClass2 but I don;t have access to the implementation of these classes (external dll). I was wondering if I can create new interface and use AutoMapper to map TestClass1 and TestClass2 to ITestInterface: public interface ITestInterface { int TestInt { get; set; } void TestMethod(); }

  • C++ and virtual methods overriding

    - by silent
    Sorry for this stupid question, but I can't find an answer by myself, I'm too new in C++ :( class DBObject : public QObject { ... protected: virtual QString tableName() { return ""; }; }; class DBUserObject : public DBObject { ... protected: virtual QString tableName() { return "profiles"; }; }; And I have this code in parent: bool DBObject::load(quint32 id) { QString query = QString("select %1 from %2 where id = :id") .arg(fieldList().join(",")) .arg(tableName()); <--- here is trouble ... } So I'm trying to execute: DBUserObject user; user.load(3); But in result I have a query with empty table name cause tableName() method returns empty string. Why not "profiles"?

  • Google App Engine: Difficulty with Users API (or maybe just a Python syntax problem)

    - by Rosarch
    I have a simple GAE app that includes a login/logout link. This app is running on the dev server at the moment. The base page handler gets the current user, and creates a login/logout url appropriately. It then puts this information into a _template_data dictionary, for convenience of subclasses. class BasePage(webapp.RequestHandler): _user = users.get_current_user() _login_logout_link = None if _user: _login_logout_link = users.create_logout_url('/') else: _login_logout_link = users.create_login_url('/') _template_data = {} _template_data['login_logout_link'] = _login_logout_link _template_data['user'] = _user def render(self, templateName, templateData): path = os.path.join(os.path.dirname(__file__), 'Static/Templates/%s.html' % templateName) self.response.out.write(template.render(path, templateData)) Here is one such subclass: class MainPage(BasePage): def get(self): self.render('start', self._template_data) The login/logout link is displayed fine, and going to the correct devserver login/logout page. However, it seems to have no effect - the server still seems to think the user is logged out. What am I doing wrong here?

When I load this settings file, I can use the variables defined in settings.php in the script itself, but not within any functions I define in it. For example, in my class definition, myclass.php: <?php $preIP = dirname(__FILE__); require_once( "preIP/settings.php" ); class MyClass { ... public function foo() { echo $variable_from_settings; } } The code in the function foo() will not work (the variable will not be defined). The settings.php file looks like this: $variable_from_settings = "bar"; Thanks,

  • Django store regular expression in DB which then gets evaluated on page

    - by John
    Hi, I want to store a number of url patterns in my django model which a user can provide parameters to which will create a url. For example I might store these 3 urls in my db where %s is the variable parameter provided by the user: www.thisissomewebsite.com?param=%s www.anotherurl/%s/ www.lastexample.co.uk?param1=%s&fixedparam=2 As you can see from these examples the parameter can appear anywhere in the string and not in a fixed position. I have 2 models, one holds the urls and one holds the variables: class URLPatterns(models.Model): pattern = models.CharField(max_length=255) class URLVariables(models.Model): pattern = models.ForeignKey(URLPatterns) param = models.CharField(max_length=255) What would be the best way to generate these urls by replacing the %s with the variable in the database. would it just be a simple replace on the string e.g: urlvariable = URLVariable.objects.get(pk=1) pattern = url.pattern url = pattern.replace("%s", urlvariable.param) or is there a better way? Thanks
