  • Accessing items at deeper levels using children() in jQuery

    - by favo
    Hi, I want to access a simple button in an unknown nested level of a container. Using container.children('button') allows me to access buttons in the first level, i.e.: <div> <button>test</button> </div> Trying to use the same with the following construct: <div> <div> <button>test</button> </div> </div> .. fails, because the button is not a direct children. I could use element.children().children('button') but the depth of the button can change and this feels too strange. I can also write my own function to iterate thru all children to find what I need, but I guess jQuery does already have selectors for this. So the question is: How can I access children in an unknown depth using jQuery selectors? Thank you all in advance for your feedback!

  • ViewController Navigating

    - by Kobe.o4
    I have 4 ViewControllers, startViewController as the initial View Controller. This contains my intro. After its finish, it will [self presentViewController:vc animated:YES completion:NULL]; into my menuViewController. startViewController ------> menuViewController ------> C1ViewController \ \ ------> ImportantViewController In my menuViewController are buttons for the two ViewController like the above illustration. Also I presented them in the View with this: [self presentViewController:vc animated:YES completion:NULL]; I return tomenuViewController with this [self dismissModalViewControllerAnimated:YES]; What I wanted is to make the ImportantViewController to be the like the parent view or the mainVIew even if I go to other Views. What I need is when ImportantViewController is presented when I go to either C1ViewController or menuViewController it wont be deallocated, or its content there will still be retained. Is it possible? And How? I don't know much about what parent and child view controllers for so I dont know what to implement in my problem. Thank you. BTW, Im using Storyboard.

  • Java JCheckBox ArrayList help needed

    - by user2929626
    I'm new to Java and struggling with something which I'm sure must have a simple answer but I can't seem to find it. I have an array of checkbox objects defined as: ArrayList<JCheckBox> checkBoxList A JPanel is created with a grid layout and the checkboxes are added to the JPanel and the ArrayList: for (int i = 0; i < 256; i++) { JCheckBox c = new JCheckBox(); c.setSelected(false); checkBoxList.add(c); mainPanel.add(c); } Yes, there are 256 checkboxes! The panel is added to a JFrame and eventually the GUI is displayed. The user can select any combination of the 256 checkboxes. My class implements Serializable and this ArrayList of checkboxes can be saved and restored using 'Save' and 'Load' GUI buttons. My code to load the saved object is as below: public class LoadListener implements ActionListener { public void actionPerformed(ActionEvent a) { try { // Prompt the user for a load file JFileChooser fileLoad = new JFileChooser(); fileLoad.showOpenDialog(mainFrame); // Create a object/file input stream linking to the selected file ObjectInputStream is = new ObjectInputStream(new FileInputStream(fileLoad.getSelectedFile())); // Read the checkBox array list checkBoxList = (ArrayList<JCheckBox>) is.readObject(); is.close(); } catch (Exception ex) { ex.printStackTrace(); } } On loading the ArrayList object, the values of the checkboxes are correctly populated, however I want to update the checkboxes on the GUI to reflect this. Is there an easy way to do this? I assumed as the array of checkboxes had the correct values that I could just repaint the panel / frame but this doesn't work. I'd like to understand why - does my loaded array of checkbox objects no longer reflect the checkbox objects on the GUI? Any help would be much appreciated. Thanks!

  • Create ImageButton programatically depending on local database records

    - by user2507920
    As i described in title, i have a local db in sqlite. I want to create ImageButton parametrically. How many times is local database loop executing? Please see code below : RelativeLayout outerRelativeLayout = (RelativeLayout)findViewById(R.id.relativeLayout2_making_dynamically); db.open(); Cursor c = db.getAllLocal_Job_Data(); if(c!=null){ if(c.moveToFirst()){ do { RelativeLayout innerRelativeLayout = new RelativeLayout(CalendarActivity.this); innerRelativeLayout.setGravity(Gravity.CENTER); ImageButton imgBtn = new ImageButton(CalendarActivity.this); imgBtn.setBackgroundResource(R.drawable.color_001); RelativeLayout.LayoutParams imageViewParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT); imgBtn.setLayoutParams(imageViewParams); // Adding the textView to the inner RelativeLayout as a child innerRelativeLayout.addView(imgBtn, new RelativeLayout.LayoutParams( ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); outerRelativeLayout.addView(innerRelativeLayout, new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); } while (c.moveToNext()); } } db.close(); But when i run the project, i can see only one button created there. I think there are many buttons but here image button is creating on last created image button. I think i should use android:layout_toRightOf with previous created button but i cant find how to place it here. I have tried some ideas but it did not change any thing. So please anybody has any idea to solve my problem then please share it with me.

  • Does jquery live slow down websites?

    - by chobo2
    Hi I have a problem I am using jquery U.I tabs that load everything with ajax. Now I have it right now everytime you click on a tab a partial view is loaded up into that tab. Now in this partial view their are javascript files that use jquery to bind all the events that are needed in that tab plus some jquery plugins I am using. Now every time that tab is loaded up all those scripts are loaded up. If it is clicked 10 times then those scripts are loaded 10times up meaing now each of say my buttons will now have 10 of the same events on it mean if someone clicks on that button 10 events will all fire off to and do the same thing. So I need to find some solution to either move all the script out and have it on the main page and use jquery.live or some other solution. I tried to do use jquery caching for the U.I tabs but this won't work since some things in say Tab A when changed effect Tab B meaning I need Tab B to be reloaded but the scripts can't reload otherwise I run into the same problem as now.

  • jQuery scroll div with scrollTop

    - by papermate
    I'm trying to scroll a div up or down when hovering over the respective arrows. I also want to be able to jump down the div when the buttons are clicked (think clicking the windows scroll arrows rather than dragging the scroll bar). The scrolling works but the jumping doesn't. scrollTop() keeps retuning 0. Here's the code: function startScrollContent() { if ($('.haccordion-opened').prev('.header').find('div').attr('title') != 'dontscroll' && $('.haccordion-opened span.arrow').length == 0) { $('.haccordion-opened').append('<span class="arrow down" style="position: absolute; bottom: 5px; left: 260px; font-size: 9pt;">&#9660;</span><span class="arrow up" style="position: absolute; bottom: 5px; left: 280px; font-size: 9pt;">&#9650;</span>'); $('.content span.arrow').hover(function() { direction = ($(this).hasClass('up')) ? '-=' : '+='; $('.content .padding').animate({scrollTop: direction + $('.content .padding').css('height')}, 5000); }, function() { $('.content .padding').stop(); }); $('.content span.arrow').click(function() { $('.content .padding').stop(); direction = ($(this).hasClass('up')) ? '-' : '+'; alert($('.content .padding').scrollTop()); //$('.content .padding').scrollTop($('.content .padding').scrollTop + direction + 100); }); } return; } How can I get the jump part working?

  • Dealing with Struts2 float conversion type

    - by Daniel Calderon Mori
    I have a question regarding float type conversion in Struts2. I have a form that contains a serie of normal input elements. A serie of textfields with an add button by the side of each one is included in the window. Clicking on one of this buttons has the effect of adding an input type "hidden" inside the form with the value of its correspondent textfield. That value will often be a float number that, this is very important, uses the point format (example: 1.34). The inputs created look like this: <input class="hidden_material" type="hidden" name="form[0].cantidad_formulacion" value='1.34'"> <input class="hidden_material" type="hidden" name="form[1].cantidad_formulacion" value='1.54'"> Anyway, the whole proccess is made correctly until the data is used by the server after the form submission. The numbers are present as if the point wouldn't have been placed in the number (using the example above, as 134). If a comma is used (as in 1,34), there wouldn't be a problem. But that will not be the case with the users of the system. How could I solve this problem?

  • Android - update widget text

    - by david
    Hi, i have 2 questions about widgets update I have 2 buttons and i need to change one button text when i press the other one, how can i do this? The first time i open the widget it calls the onUpdate method, but it never calls it again. I need to update the widget every 2 seconds and i have this line in the xml. android:updatePeriodMillis="2000" Do i need a service or should it works just with the updatePeriodMillis tag? onUpdate method RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.newswidget); Intent intent = new Intent(context, DetalleConsulta.class); intent.putExtra(DetalleConsulta.CONSULTA_ID_NAME, "3"); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); views.setOnClickPendingIntent(R.id.btNews, pendingIntent); /* Inicializa variables para llamar el controlador */ this.imei = ((TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE)).getDeviceId(); this.controlador = new Controlador(this.imei); try { this.respuestas = this.controlador.recuperarNuevasRespuestas(); if(this.respuestas != null &amp;&amp; this.respuestas.size() &gt; 0){ Iterator&lt;Consulta&gt; iterRespuestas = this.respuestas.iterator(); views.setTextViewText(R.id.btNews, ((Consulta)iterRespuestas.next()).getRespuesta()); } } catch (PersistenciaException e) { //TODO manejar error } appWidgetManager.updateAppWidget(appWidgetIds, views); thx a lot!!!

  • MS Access Form - Horizontal Anchor Affecting Data Update

    - by nicholas
    Running Access 2007 with a databound form. The form Record Source is set to a query, and all fields in the form have a defined Control Source; nothing fancy, just field names. The form is a Single form with record navigation buttons which perform a "Next Record" and "Previous Record" actions. As I navigate the records the controls in the header update correctly. However, if I change a control Horizontal Anchor property to "Right" the fields no longer update on record navigation. This is observed for both text box and combo box controls. I can switch the anchoring back to "Left" and the updating works as it should. Is there some reason anchoring would affect a control updating of in an Access form? Or is this a bug that has been observed before? The only workaround I can think of is to assign the control text/value property in the form OnCurrent event, but this seems somewhat sloppy. Am I missing something here?

  • How: Start an Activity inside a Thread and use finish() to get back.

    - by Kirk Becker
    Hello, I am programming a game on android. I'm using a Thread while calling a Surface View class to update and draw my game. Inside the update I wanted to start an activity based on if the game has just started and this would launch my MENUS. My Thread for the most part.. while (myThreadRun) { Canvas c = null; try { gameTime = System.currentTimeMillis(); c = myThreadSurfaceHolder.lockCanvas(null); synchronized (myThreadSurfaceHolder) { // Update Game. myThreadSurfaceView.onUpdate(); // Draw Game. myThreadSurfaceView.onDraw(c); You can see there where I am updating the game... here is onUpdate(); protected void onUpdate() { // Test if menu needs to be displayed. while (thread.getMenu()) { // Test if menu activity has been started. if (thread.getMenuRunning() == false) { Intent menuIntent = new Intent(this.getContext(), MyMenu.class); ((Activity) cxt).startActivityForResult(menuIntent, 1); thread.setMenuRunning(true); } } I am using a while loop because if I didn't use it the thread just keeps going. Basically I just don't know how to implement my menus using a thread as a game loop. Everywhere I look it seems like that's best practice. In my menu activity I just display the menu layout and a few buttons and when the person wants to start the game it uses finish() to go back to my thread where they play the game. I am very new to this so any insight will be helpful, Thanks

    I'm very new to flash and I really have no idea what I'm doing. Thank you in advance. its giving me that error after I click a button to go to another frame.

  • How to return a variable from a javascript function into html body.

    - by anthr
    Hi there, I am still new to javascript, and I am trying to get a function to return a variable using html & javascript. Basically the function should just return whichever radio button that the user clicks on, although at the moment I don't see anything being returned at all. The function is here: <script type="text/javascript"> function GetSelectedItem() { var chosen = "" len = document.f1.r1.length for (i = 0; i <len; i++) { if (document.f1.r1[i].checked) { chosen = document.f1.r1[i].value } } } return chosen </script> And then in the html section I have these radio buttons, and my attempt to get the variable "chosen" output to the screen. <form name = f1><Input type = radio Name = r1 Value = "ON" onClick=GetSelectedItem()>On <Input type = radio Name = r1 Value = "OFF" onClick =GetSelectedItem()>Off</form> <script type ="text/javascript">document.write(chosen)</script> At the moment nothing seems to be getting returned from the function (although if I output the variable 'chosen' inside the function then it is working correctly. Thanks in advance!

  • odd behavior when checking if radio button selected in jQuery

    - by RememberME
    I had the following check in my jQuery which I thought was working fine to see if a radio button was checked. if ($("input[@name='companyType']:checked").attr('id') == "primary") { ... } Here's the radiobuttons: <p> <label>Company Type:</label> <label for="primary"><input onclick="javascript: $('#sec').hide('slow');$('#primary_company').find('option:first').attr('selected','selected');" type="radio" name="companyType" id="primary" checked />Primary</label> <label for="secondary"><input onclick="javascript: $('#sec').show('slow');" type="radio" name="companyType" id="secondary" />Subsidiary</label> </p> Then, it suddenly stopped working (or so I thought). I did some debugging and finally realized that it was returning an id of "approved_status". Elsewhere on my form I have a checkbox called "approved_status". I realized that when I originally tested this, I must have testing it on records where approved_status is false. And, now most of my approved_statuses are true/checked. I changed the code to this: var id = $("input:radio[@name='companyType']:checked").attr('id'); alert(id); if (id == "primary") { And it's now properly returning "primary" or "secondary" as the id. So, it is working, but it seems that it's not checking the name at all and now just checking radio buttons. I just want to know for future use, what's wrong with the original code b/c I can see possibly having 2 different radio sets on a page and then my new fix probably wouldn't work. Thanks!

  • iPhone rotation woes

    - by skooter500
    I have been spending many frustrating hours trying to get rotations working on the iPhone version of Tunepal. Firstly, I have a tab bar controller, with a navigation controller controlling each of the views. I actually only want one of my views to be able to rotate and that is the TuneDisplay. I have a subclassed the UITabBarController and overridden theshouldAutorotateToInterfaceOrientation: (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation) interfaceOrientation { if (self.selectedViewController != nil) { return [self.selectedViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation]; } else { return (interfaceOrientation == UIInterfaceOrientationPortrait); } } In each of the view controllers for each of the tabs I have overridden the method and returned YES for each orientation I want to support. All well and good and everything works as it should. If I try and do a rotation on a tab that doesn’t support the rotation, nothing happens. The problem occurs if I move from a tab thats rotated to a tab that isnt supposed to support that rotation. The new tab is displayed rotated too! Screenshots for all this are included here: http://tunepal.wordpress.com/2010/04/20/rotation-woes/ Is there any way I can make it rotate back to portrait on tapping the tab? I have tried the unsupported setOrientation trick, but firstly it doesnt work correctly and secondly I received a warning from Apple for including it in my last build. If (as I suspect) there is no way to limit this behavior: How do I make the microphone image scale when I rotate the device? How do I make the buttons and the progress bar expand to fit the witdh of the toolbar? Also, one of the tabs that rotates ok has a table, with a search bar. The first time I rotate to the right or to the left, I get a black bar to the right of the search bar. If I subsequently rotate back and rotate again, the bar disappears! I have enabled the struts and springs things on the search bar in the interface builder and it looks like it should behave correctly. Any ideas about how to fix this? Ideas, feedback much appreciated Bryan

  • Creating dynamic icons based on data entered into database from django forms

    - by John Hoke
    So I'm using Django to create a projects page with multiple forms for each project. Let's call them form 1, 2, 3, and 4. Once you create a project you can fill out any of these forms. I want to create "buttons" or links for each one of the forms that would show up on the main page. Now this is the part I need help with: Step 1. I want it so that if you click on a button for a form (say form 1) and none exists for that project yet a pop up would come up saying "This form does not exist yet, are you sure you want to create one?". And if you'd answer yes you would be directed to the form page. Step 2. But if that form does exist, I don't want any pop up to open and I want the link to take the user directly to that page. Step 3. My next problem is this. These forms are in order, so if you didn't create form 1 but created form 2, I don't want to give the user access to form 1. So in this scenario, if you click on form 1 I want a pop up to open and say "This form can no longer be created", and the link wouldn't function anymore. Basically the button will have 3 function. First it should look at the database and if data for that specific form exists it should do "Step 2", if data for that form and the proceeding forms don't exist it should do "Step 1", and if data for that form doesn't exist but data for proceeding form's does exist is should do "Step 3". Is this possible? Please help as I need to find a solution to this soon. Any help would be highly appreciated. Thank you

  • Recommendation for a Pagination procedure AJAX PHP

    - by Jamex
    Hi, I am not sure the correct terminology for the process that I am trying to describe. I don't even know which platform is underlying the technique. If you understand my description, please give the link to the site(s) and or the keyword name of the process. I think it is done by AJAX, but I am not certain. I use php as the backend code, I just need to find a way to dynamically display the results. Please give suggestions. I forgot the name of the sites that use this, and my link history expired. TIA Description: The page would have a search form and options. After the user submits, the search is initiated, and the results appear inside the dedicated result area. The page does not refresh, just the info inside the result area. The display area will show 20 (or whatever) results (lines). There will be next, and previous buttons. If you hit next, the next set of results will display. I am writing a code that generates 20 results for each display. There is no set number of results, so the results might have a start/first page, but do not have an end page. Each time the user hits 'next', the program would generate/load new results. It would also store previous results, so that when a user hits 'prev', the previous results can instantly come up. What techniques/program are theses?

  • UIComponent in Swc

    - by mustISignUp
    In Flash, if i create a custom Movieclip, and compile it to a SWC, i can use it in .fla files (by linking to the .swc).. var mcInstance = new CustomMovieClip(); addChild(mcInstance); All the arrangement of graphics on the custom movieClip's layers is preserved. If i subclass UIComponent and compile to a swc, I can use the custom Class in my .fla file, but the new instance doesn't seem to construct the children arranged on the layers. I know that the correct way to make a custom component is to have the two frames, first to specify bounding box, second frame for assets, and that the first graphic in frame 1 is removed at runtime. But i'm not really trying to make a reusable component - i just want to use the UIComponent class (It seems to have some nice extensions to Sprite). As i really want some hand-positioned layers inside the component i figured i could have the bounding box as the first element on frame 1 (knowing that it would be removed), but any other items i put on frame 1 would be preserved - buttons, images, lines, etc. Is this possible?

  • Passing trough a datagrid value

    - by Tonz
    I have a datagrid with 2 columns. One databound which display names and the other one is a hyperlink column. Column1 = databound column, Column2 = hyperlink column. column1: column2: --------------------- Name1 Modify Name2 Modify Next when i click on any of the values in Column2 i simply get redirected to a other page. This page contains 2 buttons/hyperlinks with Yes or No. (does not mather wich control, which one would bring the most easy to implement solution atm) When clicked on No it simply redirects back to the orignal page. Now the question is when i press "Yes" how exactly do i acces "Name1" (or Name2 if i press on the second modify)? Meaning if i press Yes i want to use this Name for certain opertions (xml). To put it short if i press on "modify" i want to be able to get that name associated with it (which is already displayed in the first bound column left of it). So the goal is to use that name in Xpath for example so i can make a query towards that node with that certain name. Hopefully this made some sence.

I looked around some questions. they did not answer clearly what I am looking for.hence the posting. thanks.I think I was adding my own Back button on the Layout I created in the Class B's UI Screen --not using the regular "Back" button on the key board. May be that was the problem.

  • How to get VC# to rebuild auto-generated .cs files?

    - by Jive Dadson
    I imagine this question has been asked and answered, but I cannot find it. I wanted to make a simple GUI to interface to a windows 7 command. I usually use Wx, but since this was to be a windows-only thing, I decided to see if I could whip it out real fast using Visual C# 2010 Express, which I had never used before. Things started off just great. I created a form, put a few buttons and text boxes and such on it, and hit Debug. It came up and ran just like that. No muss, no fuss. So I then designed the form just the way I wanted it, renamed the controls from "Button1" and so forth to meaningful names. But now it's a mess. By clicking around, I discovered that VC# had auto-generated two files called Form1.cs and Form1.Designer.cs. The later contains the bindings between functions and the events generated from user-clicks etc., and the former contains no-op code for those functions, for me to complete. Problem is, the names are all still the original "Button1" and so forth, not the new ones, and the new controls I added after running the first time do not appear at all. I want it to regenerate all that stuff afresh from the finished form. How to?

  • IE8 and below <input type="image"> value work around

    - by kielie
    Hi guys, I have a slight problem, I am trying to capture the input of two buttons, one yes, one no, into a database but for some reason the database doesn't always show the value of the button clicked, it just shows up blank. <form action="refer.php" method="post" id="formID" > <div class="prompt_container" style="float: left;"> <span class="prompt_item"><input type="image" src="images/yes.jpg" alt="submit" value="yes" onclick="this.disabled=true,this.form.submit();" /></span> <input type="hidden" name="refer" value="yes"> </div> </form> <form action="thank_you.php" method="post" id="formID" > <div class="prompt_container" style="float: right;"> <span class="prompt_item"><input type="image" src="images/no.jpg" alt="submit" value="no" onclick="this.disabled=true,this.form.submit();" /></span> <input type="hidden" name="refer" value="no" > </div> </form> Apparently anything lower than IE8 will ignore the value attribute of all form inputs. How could I get this to work properly in all browsers? jQuery or Javascript maybe?

  • What is the common way to program action listeners?

    - by Roman
    I just started to learn how to use action listeners. To my understanding it works in the following way: There are some classes which contains "addActionListener" method by default (for example classes for buttons). Using this method we add an action listener to an object. For example: listenedObject.addActionListener(listeningObject). When an action with the "listenedObject" is performed, the "actionPerformed" method of the "listeningObject" will be called. So, it means that when we program a class for the listeningObject, we need to put there "actionPerformed" method. What is not clear to me, should we create a new class for every object that we want to listen. It does not seem to me as an elegant solution. On the other hand, if we have one action listener class for all (or at least many) object, than we have a problem since a instance of this class will not know which object is calling the "actionPerformed" method (and we need to know that since actions performed by the actionPerformed differs depending on who is called for this method). In my opinion, for every listened object we need to create are "personal" action listener and we can do it by setting a specific value to the corresponding field of the action listener. But I am not sure that it is a standard way to go? How do usually people do it?

  • Required attribute HTML5

    - by Joop
    First of all I will explain how I stumbled into this behavior. Within my web application I am using some custom validation for my form fields. Within the same form I have two buttons. One to actually submit the form and the other to cancel/reset the form. Mostly I use Safari as my default browser. Now Safari 5 is out and suddenly my cancel/reset button didn't work anymore. Every time I did hit the reset button the first field in my form did get the focus. However this is the same behavior as my custom form validation. When trying it with another browser everything just worked fine. I had to be a Safari 5 problem. I changed a bit in my Javascript code and I found out that the following line was causing the problem: document.getElementById("somefield").required = true; To be sure that would be really the problem I created a test scenario: <!DOCTYPE html> <html> <head> <title>Test</title> </head> <body> <form id="someform"> <label>Name:</label>&nbsp;<input type="text" id="name" required="true" /><br/> <label>Car:</label>&nbsp;<input type="text" id="car" required="true" /><br/> <br/> <input type="submit" id="btnsubmit" value="Submit!" /> </form> </body> </html> What I expected would happen did happen. The first field "name" did get the focus automatically. Anyone else stumbled into this?
