  • Switching Javascript Function states

    - by webzide
    Dear experts, I would like to implement a API of Javascript that sort of resemble a light switch. For instance, there are two buttons on the actual HTML page act as the UI. Both of the buttons have event handlers that invokes a different function. Each function have codes that act like a state, for instance. button1.onclick=function (){ $("div").click( //code effects 2 ) } button2.onclick=function (){ $("div").click( //Code effects 2 ) } I the code works fine on the surface but the 2 state functions overlap. the effects is going to take place for the rest of the way until the next reload of the document. Basically what I want to achieve is that when 1 button is clicked, it will switch "OFF" the state of function invoked by the other button and vice versa. Thus, the effects achieved are unique are not overlapped. Is there anyway to achieve this or could any experts point me to the right direction. Thanks in advance.

  • Silverlight Close/Cancel button

    - by Fizz
    This is for Silverlight 4, I want to create a new button class for a close/cancel button to use on dataentry screens. The aim is to move the "confirm cancel" interaction to the control rather than having it in the ViewModel. Functional outline: 1) Have a property IsDirty, needs to support binding 2) Has two "states", controled by IsDirty IsDirty = false - Content is "Close" IsDirty = true - Content is "Cancel" 3) When clicked if it is Dirty show a message box to confirm cancel, before calling the command 4) Both states will call the command Usage would be <i:CancelButton Command="{Binding Path=CloseCommand}" IsDirty="{Binding Path=IsDirty}"/> I am looking for pointers, I think a Templated Control would be the best option, but need some guidance on how to do this

  • dojo.connect won't connect 'onclick' with button

    - by Daniel
    I'm running into a problem using dojo.connect() to connect an 'onclick' event with this button: <button dojoType="dijit.form.Button" widgetId="inbox_button" id="inbox_button">Inbox</button> and the code making the connection is: var inbox_button=dojo.byId("inbox_button"); dojo.connect(inbox_button,'onclick',function(){ var container=dijit.byId("center"); container.addChild(new dijit.layout.ContentPane({region: "left", content: "...", style: "width: 100px;"})) }); However, instead of executing the function when the button is clicked, ANY onclick event triggers the function, and I end up with a lot of children containers. Even though I'm pretty certain the .connect() function should be available as part of dojo's base functionality, I've 'required' it explicitly: dojo.require("dojo._base.connect"); Any ideas as to why this might be happening?

  • Toggling audio on click?

    - by angela
    please look at this fiddle http://jsfiddle.net/rabelais/yLdkj/1/ The above fiddle shows three bars that on hover play audios. How do I change this so the music plays and pauses on click instead. Also if one audio is playing and another is clicked how can the already playing song pause? $("#one").mouseenter(function () { $('#sound-1').get(0).play(); }); $("#one").mouseleave(function () { $('#sound-1').get(0).pause(); }); $("#two").mouseenter(function () { $('#sound-2').get(0).play(); }); $("#two").mouseleave(function () { $('#sound-2').get(0).pause(); }); $("#three").mouseenter(function () { $('#sound-3').get(0).play(); }); $("#three").mouseleave(function () { $('#sound-3').get(0).pause(); });

  • How can I collapse a nested list using jQuery?

    - by Bradley Herman
    I have a nested list: <ul> <li><a href='#'>stuff</a></li> <li><a href='#'>stuff2</a></li> <ul> <li><a href='#'>stuff3</a></li> </ul> <li><a href='#'>stuff4</a></li> </ul> ...and want to collapse the nested ul when the li is clicked. Before I was using $('UL LI').click(function(){ $(this).next().slideToggle(); }); ...but this obviously causes a problem when a li doesn't have a ul nested after it. Is there a better way to do this, or is there a way for me to determine if the object returned by $(this).next() is a UL?

  • Can a variable bu used 2nd time after releasing it?

    - by Jakub
    Hello, I try to understand the memory management in ObjectiveC and still some things are a misery for me. I've got an instance variable: NSMutableArray *postResultsArray; when a button is clicked in the UI I create new array: self.postResultsArray = [NSMutableArray array]; then I add some objects to the array and when the whole operation is done I would like to release the array: [self.postResultsArray release]; (I assume that all the objects stoed in the array will be released along with the array). The problem appears when I click the button again and in the code I want to create the array again with: self.postResultsArray = [NSMutableArray array]; I get: [CFArray release]: message sent to deallocated instance 0x3d9e390 Can't I initialize the same instance variable for the second time? or maybe I should not release it? and if so, why? Thanks!

  • calling a method on the parent page from a user control

    - by Kyle
    I am using a user control that I created (just a .cs file not an .ascx file), that does some magic and depending on a value generated by the control, I need it to do something on the parent page that is 'hosting' the control. It needs to call a method under certain circumstances (method is on the parent control). the control is placed on the parent page like so: <customtag:MyControl ID="something" runat="server" /> I'm dynamically creating buttons etc on the control itself but when a button is clicked, let's say for example that there's a text box on the control and if the value of the textbox is "bob" it needs to call a method on the page that's housing the control...how can I accomplish this?

  • Get the WPMU default blog domain

    - by RobertWHurst
    I have a network of blogs that link to each other. The problem is when I want to get the primary blog's domain. I need it for things like the the target of the logo when clicked. I can't seem to find a function in WPMU the retrieves this. I can see the value I want in the wp_site table. I could easily get it with $wpdb, but its a bit over kill, and if there is a function that can get the value already, then I want to use it.

  • UISearchDisplayController automatically creates a UIPopovercontroller to display content search result ?! How to dismiss it ?

    - by yonel
    Hi, I'm using a UISearchDisplayController with a UISearchBar. I put this UISearchBar in my app using IB and I get : Fine : when you start taping, the result popovercontroller appears magically (I didn't write anything on my own to make it appear !) Then, when a row is clicked among the result, I want to dismiss the PopoverController BUT at this stage, I never instantiated the UIPopoverController on my side : it looks like if there's an encapsulated behavior in the UISearchDisplayController that automatically wraps its searchContentsController inside a UIPopoverController. That's really great because everything works perfectly without doing anything except that I cannot get the reference to this UIPopoverController to dismiss it :( Does anyone know how to get the reference to this "magically" created UIPopoverController ? (this is the proof the iPad is really a "magical" device ;) I thought there would be a reference to the UIPopoverController from its contentController (through its parent property for instance), but I cannot find any way to get a pointer to it :/

  • Swing- focus problem

    - by AlonaK
    Hi, In my application I have a frame, with toolbar (the toolbar contains some actions). I want the toolbar to be visible only when the window is focused. So, I registered a windowFocusListener on the window. The problem is- when the window is not focused and I click on the place where a tool bar action should be- the action is performed. This happens because the WindowFocusGained is called before the mouse button is released and when the mouse button released it calls the actionPerformed. Does anybody has any idea for a work around for this problem? Does anybody know how to determine wether the mouse button is clicked now?

  • How can I have a smooth animated move between 2 Google Maps locations?

    - by pelms
    When clicking from one marker to another in Google Maps, the map screen animates the move smoothly if both markers are within them initial map view but jumps if one of the markers is off screen. I'm trying to set up a map which has several locations within the main map area but has one which is 'off screen'. I have a signpost icon to the more distant location within the initial map area which I want to smoothly scroll to the off screen location when clicked (so as to give a better sense of it's relative location). I can't find anything in the Maps API which would let me do this however. I could zoom out, move and then zoom in again but this looks a bit jarring. Am I missing something in the API, or does anyone have any suggestions?

  • How do I get a MessageBox like information window to appear in Java?

    - by John McClane
    I'm learning Java and I have no idea how to do this. I dragged a button on the form in Netbeans, double clicked it and it created this event: @Action public void HelloClickMethod() { JOptionPane.showMessageDialog(this, "The message!", "This is supposed to be the MessageBox title."); } This is the exception the IDE brings up. Cannot find symbol. Symbol: showMessageDialog() Edit 1 Now I changed it to this: @Action public void HelloClickMethod() { JOptionPane.showMessageDialog(this, "The message!", "This is supposed to be the MessageBox title.",JOptionPane.ERROR_MESSAGE); } However the IDE is saying I have an error in the word 'this'. "Cannot find symbol". I don't understand. Why is it so dificult and why are the errors so esoteric. :P

  • How to automate the finding of an M value along a route

    Kirk Kuykendall had given a script example a few years back in an ESRI forum http://forums.esri.com/Thread.asp?c=93&f=996&t=88246&mc=4 as to how to find the M (measure) value of a point in a shapefile along a route when you clicked on the point. This is very handy, BUT..I have 1500 points that I need M values for. Is there a way to automate this type of thing? I need the M values for the points to create linear events on the route. Note: I am not a programmer, but have people who can help me out.

  • Chrome and its Spellcheck -- How Hard Would This Be To Implement

    - by bobber205
    From a programmer's perspective. The dictionary in chrome, Google's "own" browser, does not have the same dictionary as their search engine. Countless times I have right clicked on a poorly misspelled word only to have no correct spelling appear. I Google the word and almost 100% of the time it knows what I was trying to type. :) I realize there are probably very good reasons for this, but why can't Chrome simply Google for a word when you right click on it when it can't find a correct spelling. I am sometimes a bad speller and it would be really nice if the spell check in Chrome at least utilized Google's landmark product to provide more accurate word spelling lookups. How hard must this be to implement or are there other reasons you think they are not?

  • How to launch a mac application without a terminal window.

    - by KPexEA
    I've written an open-source c++ application and it works fine on Windows and Linux, I finally got a Mac Mini (with 10.5.8) so I've just been testing the Mac version. My application works fine when running it from inside a terminal window and typing ./appname , but if instead I double click on it from the finder, then it opens a termnial window first and then runs my app but it doesn't seem to set the working directory to the correct location so my app dies. How do I make my app so when it launches by being double clicked on it doesn't open a terminal window first and how can I have the current directory set to the apps location automatically?

  • Hiding/Unhiding Control in Gridview’s column - shifting problem

    - by lupital
    This is a follow up to my previous question: link text In gridview's column i have a linkbutton and a label under it. I want to hide/unhide label when linkbutton is clicked. I use javascript because i don't want any postbacks. The code: protected void gvwComments_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { LinkButton lButton = ((LinkButton)e.Row.Cells[2].FindControl("lbtnExpand")); Label label = ((Label)e.Row.Cells[2].FindControl("lblBody")); lButton.Attributes.Add("onclick", string.Format("HideLabel('{0}'); return false;", label.ClientID)); } } function HideLabel(button) { var rowObj = document.getElementById(button); if (rowObj.style.display == "none") { rowObj.style.display = "block"; } else { rowObj.style.display = "none"; } } The problem is that when I unhide the label by clicking on button, linkbutton is shifted a a bit upper it's original position in the cell. Is it possible to preserve linkbutton's position in the gridviews cell?

  • Changing the color of a Rebol button

    - by Dave Matuszek
    I want to ask multiple choice questions in Rebol. Possible answers will be on buttons. I want to turn a button red when it is clicked and it is the wrong answer. When the correct button is pressed, I want to proceed to the next question. I can change the color of a box (mybox/color: red show mybox). I can set up a toggle with two colors (but I can't change it based on the result of an arbitrary test (is the answer correct?). It seems like there is probably a simple way to change the color of a button, without having to create my own button-like face objects. Isn't there?

  • In Windows 7, clicking between file explorer windows does not generate window events. What's up?

    - by asmw
    I have a custom made global hook installed and am monitoring for window messages when file explorer windows are clicked on. The funny thing is that they don't generate any window messages! I click between two file explorer windows and nothing. No VM_CREATE, no VM_ACTIVATE. Nothing. Why is this? Spy++ crashes on my machine so I can't use it but my hook is pretty good and should pick everything up. For some reason these windows just don't function like normal windows in that they don't generate the standard window messages when they become active. It seems windows 7 does not see them as normal windows? what's going on?

  • Element point map for html5 canvas element, need algorithm

    - by Artiom Chilaru
    I'm currently working on a pure html 5 canvas implementation of the "flying tag cloud sphere", which many of you have undoubtedly seen as a flash object in some pages. The tags are drawn fine, and the performance is satisfactory, but there's one thing in the canvas element that's kind of breaking this idea: you can't identify the objects that you've drawn on a canvas, as it's just a simple flat "image".. What I have to do in this case is catch the click event, and try to "guess" which element was clicked. So I have to have some kind of matrix, which stores a link to a tag object for each pixel on the canvas, AND I have to update this matrix on every redraw. Now this sounds incredibly inefficient, and before I even start trying to implement this, I want to ask the community - is there some "well known" algorithm that would help me in this case? Or maybe I'm just missing something, and the answer is right behind the corner? :)

  • Request attributes in jsf / icefaces behaves strange (survive request end)

    - by hubertg
    I have the following code in a listener method: FacesContext.getCurrentInstance().getExternalContext().getRequestMap().put("time", new Date()); When a button is clicked the following code is executed System.out.println(FacesContext.getCurrentInstance().getExternalContext().getRequestMap().get("time")); One could except that "time" is null when the listener was not executed while processing the current request, but: it seems like the "time" object survives the request processing. So when "time" has been set sometimes in the past it stays there... can anybody explain this? Thanks.

  • link_to for calling an action, instead of a button_to

    - by Brian Roisentul
    I'd like to call an action with a link_to button without being redirected to another page(I don't want ajax). For you to have an idea, I'm trying to accomplish a sort "link button" in a search page. So, when the link is clicked, the page should be refreshed showing the list ordered as I tell it in the action. If I do the following in my view, it will ask me for a template called as the action, and I don't want it: <%= link_to 'M&Aacute;S RELEVANTES', search_filter_relevance_path %> My routes file looks like this: map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance' And my controller looks like this(I haven't developed the functionality yet): def search_filter_relevance end Any help on this will be appreciated.

  • Delphi for PHP - location of source

    - by Holgerwa
    I just installed Delphi for PHP to get an idea on how it works and have created a simple app with a button that puts a text into a listbox when it is clicked. The app works if I copy all required files to my webserver and run it from there. It also works if I save the project in the standard path: "c:\documents and settings\username\My Documents\Delphi for PHP Projects" But if I save the project in another directory, the ButtonClick event is not fired when the application runs from there. I've put a breakpoint in the event to see if it stops there but it doesn't. The OnShow event of the form works as usual. It really seems to be the path where the project is located to make it either work or not. As I said, I have no experience with Delphi for PHP so far, it is probably just a simple solution that I don't see...
