• jQuery class selectors with nested div's

  - by mboles57

  This is part of some HTML from which I need to retrieve a piece of data. The HTML is assigned to a variable called fullDescription. <p>testing</p> <div class="field field-type-text field-field-video-short-desc"> <div class="field-label">Short Description:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> Demonstrates the basics of using the Content section of App Cloud Studio </div> </div> </div> <div class="field field-type-text field-field-video-id"> <div class="field-label">Video ID:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> 1251462871001 </div> </div> </div> I wish to retrieve the video ID number (1251462871001). I was thinking something like this: var videoID = $(fullDescription).find(".field.field-type-text.field-field-video-id").find(".field-item.odd").html(); Although it does not generate any syntax errors, it does not retrieve the number. Thanks for helping out a jQuery noob! -Matt

• Forcing user to new page in php. (PHP newbie)

  - by JohnC

  Hello I'm a newbie web programmer. My background is writing Windows applications with sql. I'm putting together my 1st data entry screens in Php. I have a search form that links to a form that displays records in a grid. On each row of the grid I have a delete url to allow the user to remove a record. This links to a form delete.php (which calls the sql to remove the record). Ideally I would like to automatically take the user back to the search form rather than forcing the user to click on a link to do so. I have used ob_start with the header to do this elsewhere but cannot get it to work on this page. Is there another way to do it? (Using php 5 as part of LAMP) file delete.php <?php $id = $_GET['recordID']; //ob_start(); require_once('connections/local.php'); mysql_select_db($database_local, $local); mysql_query("DELETE FROM user_access WHERE id = {$id}") or die(mysql_error()); echo("Record ".$id." deleted"); echo("<br>"); //header("location:http://localhost/search7.htm); //ob_flush(); echo("<a href=\"http://localhost/search7.htm\">Search for Members</a>"); ?>

• HQL query problem

  Hi all, I'm using this hql query for my filters. Query perfectly working except width (string) part. Here is the query, public IList<ColorGroup> GetDistinctColorGroups(int typeID, int finishID, string width) { string queryStr = "Select distinct c from ColorGroup c inner join c.Products p " + "where p.ShowOnline = 1 "; if (typeID > 0) queryStr += " and p.ProductType.ID = " + typeID; if (finishID > 0) queryStr += " and p.FinishGroup.ID = " + finishID; if (width != "") queryStr += " and p.Size.Width = " + width; IList<ColorGroup> colors = NHibernateSession.CreateQuery(queryStr).List<ColorGroup>(); return colors; } ProductType and Size have same mappings and relations.

• How can we set time delay in animation of images to make them appear smooth ?

  - by srikanth rongali

  Hi, I have 10 CCSprite images. They are continues images. I am using, CCSprite *playerH = [CCSprite spriteWithFile:@"Player_01.png" ]; playerH.position = ccp(playerH.contentSize.width/2, windowSize.height/2); [self addChild:playerH z:1]; CCAnimation* animation = [CCAnimation animationWithName:@"dance" delay:0.20f]; for( int i = 1; i < 11; i++ ) { [animation addFrameWithFilename: [NSString stringWithFormat:@"Player_%02d.png", i]]; } NSLog(@"k VALUE: k: %d",k); id actionA = [CCAnimate actionWithAnimation: animation restoreOriginalFrame:NO]; id actionD = [CCDelayTime actionWithDuration:5.0f]; id actionC = [CCCallFunc actionWithTarget:self selector:@selector(enemyEntranceScreen:)]; id seqActionPlayer = [CCSequence actions:actionA, actionD, actionC, nil]; [playerH runAction: seqActionPlayer]; But the animation is not continues. I have changed the animation delay time. but, I can see only three images appearing. How can we know how much time interval should we keep in animation. Is there any relationship between this and the frame rate [[CCDirector sharedDirector] setAnimationInterval:1.0/60]; [[CCDirector sharedDirector] setDisplayFPS:YES]; Thank you.

I am thinking to load the data to a Textarea under Div tag and hide the the data: <Div id="reference" style="Display:none;"> <textarea rows="2" cols="20" id="database"> html, htm, php, asp, jsp, aspx, ctp, thtml, xml, xsl... </textarea> </Div> <table border=0 width="100%"> <tr> <td>Username</td> <td> <div id="username"> <input type="text" name="data" id="data"> </div> </td> </tr> </table> <script> $(document).ready(function(){ //comparing the data loaded from database with the user's input if($("#data").val()==$("#database").val()) {alert("error");} }); </script> I am not sure if this is the best way to do it, so could you give me some advice and suggest your methods please.

• FluentNHibernate: Not.Nullable() doesn't affect output schema

  - by alex

  Hello I'm using fluent nhibernate v. 1.0.0.595. There is a class: public class Weight { public virtual int Id { get; set; } public virtual double Value { get; set; } } I want to map it on the following table: create table [Weight] ( WeightId INT IDENTITY NOT NULL, Weight DOUBLE not null, primary key (WeightId) ) Here is the map: public class WeightMap : ClassMap<Weight> { public WeightMap() { Table("[Weight]"); Id(x => x.Id, "WeightId"); Map(x => x.Value, "Weight").Not.Nullable(); } } The problem is that this mapping produces table with nullable Weight column: Weight DOUBLE null Not-nullable column is generated only with default convention for column name (i.e. Map(x = x.Value).Not.Nullable() instead of Map(x = x.Value, "Weight").Not.Nullable()), but in this case there will be Value column instead of Weight: create table [Weight] ( WeightId INT IDENTITY NOT NULL, Value DOUBLE not null, primary key (WeightId) ) I found similiar problem here: http://code.google.com/p/fluent-nhibernate/issues/detail?id=121, but seems like mentioned workaround with SetAttributeOnColumnElement("not-null", "true") is outdated. Does anybody encountered with this problem? Is there a way to specify named column as not-nullable?

• Can't understand sessions in Rails

  - by ciss

  Hello everyone. Please don't bit my for my misunderstanding. The sessions are very new for me, and i have some problems. Okay i read many information about sessions and especially rails session. But this don't give me right imagine about sessions. Did i understand right, when users send request to server (get) - Server create a new session (and store this some file in hard drive with session id), session id - is a random generated num? so, server create a new session (and store session on drive) after this server send back answer to client and set session_id in cookies? Ok, i debug some params and see some results: debug(session): {:_csrf_token=>"jeONIfNxFmnpDn/xt6I0icNK1m3EB3CzT9KMntNk7KU=", :session_id=>"06c5628155efaa6446582c491499af6d", "flash"=>{}} debug(cookies): {"remember_user_token"=>"1::3GFRFyXb83lffzwPDPQd", "_blog_session"=>"BAh7CDoQX2NzcmZfdG9rZW4iMWplT05JZk54Rm1ucERuL3h0NkkwaWNOSzFtM0VCM0N6VDlLTW50Tms3S1U9Og9zZXNzaW9uX2lkIiUwNmM1NjI4MTU1ZWZhYTY0NDY1ODJjNDkxNDk5YWY2ZCIKZmxhc2hJQzonQWN0aW9uQ29udHJvbGxlcjo6Rmxhc2g6OkZsYXNoSGFzaHsABjoKQHVzZWR7AA==--348c88b594e98f4bf6389d94383134fbe9b03095"} Okay, i know, what _csrf_token helps to prevent csrf. session_id - is id of the session which stored on hard drive (by default) but what is _blog_session in cookies? also, remeber_user_token containes my id (1::*) and what about second part, what is it? Sorry for this stupid questions, i know what i can easy use any nice auth-plugins (authlogic/clearance/devise), but i want to fully understand sessions. Thank you. (also sorry for my english, this is not my native language)

• Have Microsoft changed how ASP.NET MVC deals with duplicate action method names?

  - by Jason Evans

  I might be missing something here, but in ASP.NET MVC 4, I can't get the following to work. Given the following controller: public class HomeController : Controller { public ActionResult Index() { return View(); } [HttpPost] public ActionResult Index(string order1, string order2) { return null; } } and it's view: @{ ViewBag.Title = "Home"; } @using (Html.BeginForm()) { @Html.TextBox("order1")<br /> @Html.TextBox("order2") <input type="submit" value="Save"/> } When start the app, all I get is this: The current request for action 'Index' on controller type 'HomeController' is ambiguous between the following action methods: System.Web.Mvc.ActionResult Index() on type ViewData.Controllers.HomeController System.Web.Mvc.ActionResult Index(System.String, System.String) on type ViewData.Controllers.HomeController Now, in ASP.NET MVC 3 the above works fine, I just tried it, so what's changed in ASP.NET MVC 4 to break this? OK there could be a chance that I'm doing something silly here, and not noticing it. EDIT: I notice that in the MVC 4 app, the Global.asax.cs file did not contain this: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults ); } which the MVC 3 app does, by default. So I added the above to the MVC 4 app but it fails with the same error. Note that the MVC 3 app does work fine with the above route. I'm passing the "order" data via the Request.Form. EDIT: In the file RouteConfig.cs I can see RegisterRoutes is executed, with the following default route: routes.MapRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }); I still get the original error, regards ambiguity between which Index() method to call.

• Are ternary operators not valid for linq-to-sql queries?

  - by KallDrexx

  I am trying to display a nullable date time in my JSON response. In my MVC Controller I am running the following query: var requests = (from r in _context.TestRequests where r.scheduled_time == null && r.TestRequestRuns.Count > 0 select new { id = r.id, name = r.name, start = DateAndTimeDisplayString(r.TestRequestRuns.First().start_dt), end = r.TestRequestRuns.First().end_dt.HasValue ? DateAndTimeDisplayString(r.TestRequestRuns.First().end_dt.Value) : string.Empty }); When I run requests.ToArray() I get the following exception: Could not translate expression ' Table(TestRequest) .Where(r => ((r.scheduled_time == null) AndAlso (r.TestRequestRuns.Count > 0))) .Select(r => new <>f__AnonymousType18`4(id = r.id, name = r.name, start = value(QAWebTools.Controllers.TestRequestsController). DateAndTimeDisplayString(r.TestRequestRuns.First().start_dt), end = IIF(r.TestRequestRuns.First().end_dt.HasValue, value(QAWebTools.Controllers.TestRequestsController). DateAndTimeDisplayString(r.TestRequestRuns.First().end_dt.Value), Invoke(value(System.Func`1[System.String])))))' into SQL and could not treat it as a local expression. If I comment out the end = line, everything seems to run correctly, so it doesn't seem to be the use of my local DateAndTimeDisplayString method, so the only thing I can think of is Linq to Sql doesn't like Ternary operators? I think I've used ternary operators before, but I can't remember if I did it in this code base or another code base (that uses EF4 instead of L2S). Is this true, or am I missing some other issue?

• Why Backbone.js isn't binding my event

  - by Saif Bechan

  I have a router like this, as main entry point: window.AppRouter = Backbone.Router.extend({ routes: { '': 'login' }, login: function(){ userLoginView = new UserLoginView(); } }); var appRouter = new AppRouter; Backbone.history.start({pushState: true}); I have a model/collection/view like this: window.User = Backbone.Model.extend({}); window.Users = Backbone.Collection.extend({ model: User }); window.UserLoginView = Backbone.View.extend({ events: { 'click #login-button': 'loginAction' }, initialize: function(){ _.bindAll(this, 'render', 'loginAction'); }, loginAction: function(){ var uid = $("#login-username").val(); var pwd = $("#login-password").val(); var user = new User({uid:uid, pwd:pwd}); } }); And body of my HTML looks like this: <form action="#" method="POST" id="login-form"> <p> <label for="login-username">username</label> <input type="text" id="login-username" autofocus /> </p> <p> <label for="login-password">password</label> <input type="password" id="login-password" /> </p> <a id="login-button" href="#">Inloggen</a> </form> Note: The HTML comes from Node.js using express.js, should I maybe wait for a document ready event somewhere? Edit: I have tried this, create the view when ready, did not solve the problem. $(function(){ userLoginView = new UserLoginView(); });

• FragmentActivity doesn't see activity in onActivityCreate(), after screen orientation changed

  - by hai bison

  I'm using Android support library v13. There is a strange thing I couldn't understand. When creating new activity, I load fragment as: Main activity layout: ... <FrameLayout android:id="@+id/fragment_1" ... /> In onCreate() of main activity: mFragment = (FragmentActivity) getSupportFragmentManager().findFragmentById(R.id.fragment_1); // if screen orientation changed, no need to create new instance of fragment if (mFragment == null) { mFragment = ...; // create new instance of fragment FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); ft.replace(R.id.fragment_1, mFragment); // because this is called ONCE, we can use this method ft.commitAllowingStateLoss(); } Now, everything works perfectly in emulators 1.5, 1.6 and 2.2. I have a phone 2.2.2. But there is an exception: if the app is running, and screen orientation changed. Inside onActivityCreated(), getActivity() sometimes returns null. This only happens in emulators 1.5/ 1.6/ 2.2. My phone 2.2.2 works very well, I test hundreds of times but never catch that bug. Even other emulators 3.x, 4.x work well too. Unfortunately I don't have phone 1.5/ 1.6/ 2.2. So did you have experience with this? Is that a bug of the support library, or emulators? Could you please help me? Thank you in advance.

• Radiobuttons and jQuery

  Hi, I have the following radiobuttons rendered in MVC : <div class="radio" id="ModelViewAd.TypeOfAd"> <input checked="checked" id="ModelViewAd.TypeOfAd_Ad" name="ModelViewAd.TypeOfAd.SelectedValue" type="radio" value="Ad" /> <label for="ModelViewAd.TypeOfAd_Ad">Annons</label><br> <input id="ModelViewAd.TypeOfAd_Auktion" name="ModelViewAd.TypeOfAd.SelectedValue" type="radio" value="Auktion" /> <label for="ModelViewAd.TypeOfAd_Auktion">Auktion</label><br> </div> Now I need to hide the id=divEndDate element based on the value on the radiogroup. I have tried this : $(document).ready(function () { $("#TypeOfAd_Auktion").click(function () { if ($(this).checked) { $("divEndDate").css("visibility", "visible"); } else { $("divEndDate").css("visibility", "hidden"); } }); $("#ModelViewAd.TypeOfAd_Ad").click(function () { if ($(this).checked) { $("divEndDate").css("visibility", "hidden"); } else { $("divEndDate").css("visibility", "visible"); } }); }); Now one of these are triggered when switching between the radio buttons?

• Grails GORM rarely works in domain classes

  - by Vena

  I have many to many relationship between User and Organization. I want to delete user from all his organizations when the user is being deleted, so this is basically what I came up with: class User { ... def beforeDelete() { def user = User.get(id) Organization.all.each { it.removeFromMembers(user) it.save() } } } This surprisingly doesn't work because User.get(id) returns null even though the user with the given id is in the database, when I look at the log, no sql statement is even executed. So I tried to use load() method insted. ObjectNotFoundException is the result then. So I tried this as I was quite desperate: def user = User.find("from User as u where u.id = ?", [1L]) This, for some reason, works. But now, the line with it.removeFromMembers(user) throws NullPointerException. I tried to put this logic in my UserController and it works! Why is this? Why can't I do this in domain classes? This makes beforeDelete hook (and all the others too) pretty useless.

• JSF redirect doesn't work

  I have a problem with redirecting a page in my JSF application. My navigation rule look like this : <navigation-rule> <from-view-id>/index.xhtml</from-view-id> <navigation-case> <from-action>#{registerBean.registerUser}</from-action> <from-outcome>success</from-outcome> <to-view-id>/confirmation.xhtml</to-view-id> <redirect/> </navigation-case> </navigation-rule> In my case the redirect tag doesn't work, the URL remains unchanged, and when I refresh the page the registerUser action is executed again. I just have no idea what I'm doing wrong; I'm not very experienced with JSF. Can anyone please tell why the redirect tag doesn't work? Thanks. (I'm using JSF 2.0 and NetBeans IDE)

• SQL query for an access database needed

  - by masfenix

  Hey guys, first off all sorry, i can't login using my yahoo provider. anyways I have this problem. Let me explain it to you, and then I'll show you a picture. I have a access db table. It has 'report id', 'recpient id', and 'recipient name' and 'report req'. What the table "means" is that do the user using that report still require it or can we decommission it. Here is how the data looks like (blocked out company userids and usernames): *check the link below, I cant post pictures cuz yahoo open id provider isnt working. So basically I need to have 3 select queries: 1) Select all the reports where for each report, ALL the users have said no to 'reportreq'. In plain English, i want a listing of all the reports that we have to decommission because no user wants it. 2) Select all the reports where the report is required, and the batchprintcopy is more then 0. This way we can see which report needs to be printed and save paper instead of printing all the reports. 3)A listing of all the reports where the reportreq field is empty. I think i can figure this one out myself. This is using Access/VBA and the data will be exported to an excel spreadsheet. I just a simple query if it exists, OR an alogorithm to do it quickly. I just tried making a "matrix" and it took about 2 hours to populate. https://docs.google.com/uc?id=0B2EMqbpeBpQkMTIyMzA5ZjMtMGQ3Zi00NzRmLWEyMDAtODcxYWM0ZTFmMDFk&hl=en_US

• jQuery AJAX PHP JSON problem

  - by Curro

  Hi Gurus I'm facing the problem of receiving an empty array when I do an AJAX request in the following way: This is the code I'm executing in JavaScript: <script type="text/javascript" src="lib/jquery.js"></script> <script type="text/javascript" src="lib/jquery.json.js"></script> <script type="text/javascript"> $(document).ready(function(){ /* Preparar JSON para el request */ var mJSON = new Object; mJSON.id_consulta = new Array; for (var i=0; i<3; i++){ mJSON.id_consulta[i] = new Object; mJSON.id_consulta[i].id = i; } var sJSON = $.toJSON(mJSON); $.ajax({ type: "POST", url: "getUbicaciones.php", data: sJSON, dataType: "json", contentType: "application/json; charset=utf-8", success: function(respuesta){ alert(respuesta); }, error: function (request,error){ alert("Error: " + request.statusText + ". " + error); } }); }); </script> And this is the code under PHP: <?php /* Decodificar JSON */ $m_decoded = $_POST; print_r($m_decoded); exit; ?> And all I get from this, using Chrome's Developer Tools is an empty array: Array ( ) Any clues on what am I doing wrong? The string sJSON is being encoded correctly, this is what I get when I do an "alert" on that one: {"id_consulta":[{"id":1},{"id":2},{"id":3}]} Thank you everyone in advance!

• How to create custom query for CollectionOfElements

  - by Shervin

  Hi. I have problems creating a custom query. This is what entities: @Entity public class ApplicationProcess { @CollectionOfElements private Set<Template> defaultTemplates; //more fields } And Template.java @Embeddable @EqualsAndHashCode(exclude={"file", "selected", "used"}) public class Template implements Comparable<Template> { @Setter private ApplicationProcess applicationProcess; @Setter private Boolean used = Boolean.valueOf(false); public Template() { } @Parent public ApplicationProcess getApplicationProcess() { return applicationProcess; } @Column(nullable = false) @NotNull public String getName() { return name; } @Column(nullable = true) public Boolean isUsed() { return used; } public int compareTo(Template o) { return getName().compareTo(o.getName()); } } I want to create a update statement. I have tried these two: int v = entityManager.createQuery("update ApplicationProcess_defaultTemplates t set t.used = true " + "WHERE t.applicationProcess.id=:apId").setParameter("apId", ap.getId()) .executeUpdate(); ApplicationProcess_defaultTemplates is not mapped [update ApplicationProcess_defaultTemplates t set t.used = true WHERE t.applicationProcess.id=:apId] And I have tried int v = entityManager.createQuery("update Template t set t.used = true " + "WHERE t.applicationProcess.id=:apId").setParameter("apId", ap.getId()) .executeUpdate(); With the same error: Template is not mapped [update Template t set t.used = true WHERE t.applicationProcess.id=:apId] Any ideas? UPDATE I fixed it by creating native query int v = entityManager.createNativeQuery("update ApplicationProcess_defaultTemplates t set t.used=true where t.ApplicationProcess_id=:apId").setParameter("apId", ap.getId()).executeUpdate();
