  • Text box loses focus when DIV is hovered

    - by Konoplianko
    Hello. I have a problem: When I enter a text into suggestion text box, popup panel appears. But when user places mouse over this popup panel with suggestions - text box loses focus. What should I do to prevent losing focus ? Example which have the same behaviour: http://demo.raibledesigns.com/gwt-autocomplete/ Thanks for any help. Update 1 SuggestionMenu which is being shown is extending MenuBar which sets focus for all menu items. void itemOver(MenuItem item, boolean focus) { if (item == null) { // Don't clear selection if the currently selected item's menu is showing. if ((selectedItem != null) && (shownChildMenu == selectedItem.getSubMenu())) { return; } } // Style the item selected when the mouse enters. selectItem(item); if (focus) { focus(); } // If child menus are being shown, or this menu is itself // a child menu, automatically show an item's child menu // when the mouse enters. if (item != null) { if ((shownChildMenu != null) || (parentMenu != null) || autoOpen) { doItemAction(item, false); } } } It's clear that i cant fix loosing focus. Now question is - how to make on pressing backspace or any key to focus on edit box? Thanks in advance

  • Using numeric values to select item from a dropdown box with JavaScript

    - by Shyam
    Hi, I have a multitude of dropdown boxes within my webpage. One of these dropdown boxes is used for a single selected value out of a list of options. <SELECT id="Box0" name=""> <OPTION value="0">none</OPTION> <OPTION value="1">first</OPTION> <OPTION value="2">second</OPTION> </SELECT> How can I add an event to this section, so when it is in focus, I could use numeric keys like 1,2.. to select an option instead of using the mouse or arrow keys for selecting an option? For clarification: if I press "1" on my keyboard, the selected value would become "first", with "2" the selected value becomes "second". I choose not to use a library/framework such as JQuery/Mootools. Thanks,

  • Javascript onclick event is not working in internet explorer 8.

    - by Mallika Iyer
    Hi, I have the following line of code that works fine in Firefox, Chrome and Safari, but not in internet explorer 8. <a href="javascript:void(0);" onclick="showHide('reading','type_r','r');">Show me the example</a> The function simply shows and hides a div on clicking the hyperlink. Is there anything I'm missing here? This is the showHide function: function showHide(elementId,parentId,qtype) { if (document.getElementById && !document.all) { var elementParent = document.getElementById(parentId); var element = document.getElementById(elementId); var upArrowId = 'up-arrow-'+qtype; var downArrowId = 'down-arrow-'+qtype; if(element.style.visibility == 'hidden'){ elementParent.style.height = 'auto'; element.style.visibility = 'visible'; document.getElementById(upArrowId).style.visibility = 'visible'; document.getElementById(downArrowId).style.visibility = 'hidden'; } else if(element.style.visibility == 'visible'){ element.style.visibility = 'hidden'; elementParent.style.height = '50px'; document.getElementById(upArrowId).style.visibility = 'hidden'; document.getElementById(downArrowId).style.visibility = 'visible'; } } } Thanks.

  • performing a javascript event without triggering that event handler

    - by bento
    In my latest code, I have an event handler for a focus on a textarea. When the user clicks on the textarea, that event-handler is triggered which sets some other DOM states based on the selected textarea. However, elsewhere in my program I want to programmatically set the focus of the textarea without triggering that event handler. I know Backbone, for instance, has a way to silently perform an action. My only pseudo-solution is to temporarily set a variable: var silence = true; And then, in my event handler, only perform the logic if silence is false. The handler is still triggered, but the logic doesn't run. Does anyone else know of better strategies for this?

  • adding new Input to jquery validationEngine form?

    - by Hailwood
    I have some fairly complex ajax logic etc going on in the onValidationComplete function for a form with jQuery Validation Engine. This is working perfect, but one thing is bothering me. in the form I have the ability to dynamically add inputs (add new row button). so my code structure wise looks like: var form = $('#myForm'); form.validationEngine('attach', {onValidationComplete:validationComplete}); $('#newInput').on('click', function(){ form.append('<input />'); form.validationEngine('detach'); form.validationEngine('attach', {onValidationComplete:validationComplete}); }); function validationComplete(form, status){/*all my logic here*/} What I don't like about it is that every time I add a new input I have to detach and then re-attach the validationEngine. Is there any way to just tell it to add the new input to it's list of inputs to validate?

  • Javascript code works only when the page loads

    - by victor
    I have a page with a dropdown and two textboxes. The javascript code checks to make sure that if the dropdown says Appointment Made or Patient Scheduled, the appropriate text boxes will have dates in them. When the page loads and the drop down shows either of the two above, all works fine but when I change the drop down the script does not work. I have put an alert statament after the third line and do see that when I make a change to patient_status, the variable a gets updated but for some reason the script fails and does not prompt. For example if the page loads and Appointment Made is selected, the script will prompt, but if I change the drop down to Patient Scheduled, it will not prompt. Thank You. function calculate() { a= document.getElementById("EditRecordpatient_status").value; b= document.getElementById("EditRecordSurgery_Date").value; c= document.getElementById("EditRecordConsult_Date").value; alert(a); alert(b); alert(c); if (a=="Appointment Made" && c=="") { alert('You have scheduled a patient for consultation but the consult date is missing!'); return false; } else if (a=="Patient Scheduled" && b=="") { alert('You have scheduled a patient for surgery but the surgery date is missing!'); return false; } else { return true; } } document.getElementById("Mod0EditRecord").onclick=calculate;

  • Adding Message Part dynamically in Receive Pipeline

    - by Sean
    Hello, I tried to create a custom pipeline component that takes a message and attaches additional another part dynamically (during Disassemble stage). I haven't set up a send port, so that I can see what BizTalk is trying to process. I can see only the body part, the additional part doesn't show up. This is the code I used: var part = pc.GetMessageFactory().CreateMessagePart(); part.Data = new MemoryStream(new byte[] {1, 2, 3, 4, 5}); inmsg.AddPart("another_part", part, false); Thank you.

  • How do I stop a routed event from triggering on specific places in XAML?

    - by cfouche
    I have the following situation: A stackpanel contains a number of elements, including some that are contained in a GroupBox. So something like this: <StackPanel x:Name="stackpanel" Background="White"> <TextBlock Text="TextBlock"/> <TextBlock Text="Another TextBlock"/> <!--plus a load of other elements and controls--> <GroupBox Header="GroupBoxHeader"> <TextBlock Text="Text inside GroupBox"/> </GroupBox> </StackPanel> I want a MouseDown in the stackpanel to trigger some Storyboard, so I've added an EventTrigger, like this: <EventTrigger RoutedEvent="Mouse.MouseDown" SourceName="stackpanel"> <BeginStoryboard Storyboard="{StaticResource OnMouseDown1}"/> </EventTrigger> This is almost right, but the thing is - I don't want the MouseDown to be picked up by the GroupBox's header or border, only by its content. In other words, I want the Storyboard to begin when someone does a mousedown on anything inside the StackPanel, except GroupBox headers and borders. Is there some way of doing this? (I've tried setting e.Handled to true on the GroupBox, but then its content doesn't pick up the mousedown anymore either.)

  • Multiple Input From Keyboard C# WPF

    - by Alex
    I am writing a Tetris clone in WPF. If I hold down the right arrow key, the current piece shifts right. For playability, I want to allow the user to press another key (i.e. F-key) and rotate the moving piece without having to let go of the right arrow key first. Currently when I do this, the piece stops shifting. My first basic attempt at this was hooking into Window_PreviewKeyDown(object sender, KeyEventArgs e) and then sending a message to the controller layer. How do I structure my input-listening code to allow this? My current code Here

  • Using JQuery to get text of a div that's a child of a header to replace a different header

    - by Stevie Jenowski
    Hello all, I'm trying to get the text contents of a .div('.child#') child of my event.target('h6.class'), and replace my other headers('h1.replacHeader#') using this script below... $('h6.class').click(function(event) { var $target = $(event.target); $('.replaceHeader1').replaceWith("<h1 class='replaceHeader1'>" + $target.children(".child1").text() + "</h1>"); $('.replaceHeader2').replaceWith("<h1 class='replaceHeader2'>" + $target.children(".child2").text() + "</h1>"); }); }); I've noticed that .text() apparently doesn't apply to an event.target... So how could I go about achieving this?

  • Remote Ajax Call in jQuery .click() function doesn't finish before going to next page.

    - by Clint
    I need to send click information on my website to a third party server using ajax (json). I am using jquery and I added the click event to certain links. In the click event I am making a json request to a remote server with the location of the click (heat map) and some other information. The problem is that the ajax function doesn't fire in time before the default link action happens. Setting async to false doesn't seem to work on remote ajax calls. I have tried preventDefault(), but then I don't know how to run the default action after the successful ajax call. Here is what I want to do: $('a').click(submit_click); function submit_click(e,fireAjax){ e.preventDefault(); cd_$.ajax({ url: jsonUrl, //remote server dataType: 'json', data: jsonData, async: false, success: function(reply){ //Run the default action here if I have to disable the default action }, }); } Any suggestions?

  • Why use event listeners over function calls?

    - by Organiccat
    I've been studying event listeners lately and I think I've finally gotten them down. Basically, they are functions that are called on another object's method. My question is, why create an event listener when calling the function will work just fine? Example, I want to call player.display_health(), and when this is fired, the method player.get_health() should be fired and stored so that display_health() has access to it. Why should I use an event listener over simply calling the function? Even if display_health() were in another object, this still doesn't appear to be a problem to me. If you have another example that fits the usage better, please let me know. Perhaps particular languages don't benefit from it as much? (Javascript, PHP, ASP?)

  • If we don't like it for the presentation layer, then why do we tolerate it for the behavior layer?

    - by greim
    Suppose CSS as we know it had never been invented, and the closest we could get was to do this: <script> // this is the page's stylesheet $(document).ready(function(){ $('.error').css({'color':'red'}); $('a[href]').css({'textDecoration':'none'}); ... }); </script> If this was how we were forced to write code, would we put up with it? Or would every developer on Earth scream at browser vendors until they standardized upon CSS, or at least some kind of declarative style language? Maybe CSS isn't perfect, but hopefully it's obvious how it's better than the find things, do stuff method shown above. So my question is this. We've seen and tasted of the glory of declarative binding with CSS, so why, when it comes to the behavioral/interactive layer, does the entire JavaScript community seem complacent about continuing to use the kludgy procedural method described above? Why for example is this considered by many to be the best possible way to do things: <script> $(document).ready(function(){ $('.widget').append("<a class='button' href='#'>...</div>"); $('a[href]').click(function(){...}); ... }); </script> Why isn't there a massive push to get XBL2.0 or .htc files or some kind of declarative behavior syntax implemented in a standard way across browsers? Is this recognized as a need by other web development professionals? Is there anything on the horizon for HTML5? (Caveats, disclaimers, etc: I realize that it's not a perfect world and that we're playing the hand we've been dealt. My point isn't to criticize the current way of doing things so much as to criticize the complacency that exists about the current way of doing things. Secondly, event delegation, especially at the root level, is a step closer to having a declarative behavior layer. It solves a subset of the problem, but it can't create UI elements, so the overall problem remains.)

  • Qt compilation and stylesheet

    - by Yosko
    Each time I compile my Qt project after modifying my qss stylesheet file, the modifications aren't taken into account, unless I rebuild everything. Any idea on a workaround for this, so that I don't have to wait 5 minutes each time I change my qss ? Notes: I use Qt 4.8, and my stylsheet is declared in a resource file (qrc). EDIT: As suggested by Luca Carlon, when a qss is reference in the project through a .qrc file, the changes in the qss don't affect the qrc, and the compiler ignores it. To avoid that, I added a Custom Build Step to my project: before the qmake step! calls a .bat file without any argument the .bat contains the real command copy /b files.qrc +,,

  • Drag and drop an image from desktop to a web text editor (implementation in javascript)

    - by fatmatto
    I tried to write reasonably short title but i failed i guess.. Hi everybody here's what i'm trying to do: I want to implement a web text editor able to recognize when the user drag a image file over it's editing surface and it automa(gically) starts the upload and insert the image near the cursor position. In other words i don't want the user to do the usual "insert-image-browse-ok". Atm i am not very good at javascript ... i know JQuery but i have not a clear idea about how to implement this... i don't know if there's an event handler able to help me in this situation... if not then there should be i think or web apps would miss some kind of interactivity. I've heard miracles about HTML5 could it help me? I've seen such things in Google Wave but that surface doesn't seem to be a form field... google lab's black magic i guess.... Thank you in advance.

  • JQuery checkbox state is updated differently between group click() and $.each(obj.click())

    - by teerapap
    The code below doesn't work in the same behavior. The sequence of click event and calling foo() is different. I want to know why they behave different sequence between call click() and iterate the objects before call click() on each. <script type="text/javascript"> function foo(obj){ alert(obj.id+" ->"+obj.checked); } function clickAll(val){ if (val) { $(":checkbox").click(); } else { $(":checkbox").each(function(i,obj){ obj.click(); }); } } </script> </head> <body> <input type="checkbox" id="check1" onclick="foo(this)" /> a <input type="checkbox" id="check2" onclick="foo(this)" /> b <input type="checkbox" id="check3" onclick="foo(this)" /> c <input type="button" onclick="clickAll(true)" value="click all" /> <input type="button" onclick="clickAll(false)" value="click all each" /> </body>

  • URLLoader.load() issue when using the same URLRequest

    - by Rudy
    Hello, I have an issue with my eventListeners with the URLLoader, but this issue happens in IE, not in FF. public function getUploadURL():void { var request:URLRequest = new URLRequest(); request.url = getPath(); request.method = URLRequestMethod.GET; _loader = new URLLoader(); _loader.dataFormat = URLLoaderDataFormat.TEXT; _loader.addEventListener(Event.COMPLETE, getBaseURL); _loader.load(request); } private function getBaseURL(event:Event):void { _loader.removeEventListener(Event.COMPLETE, getBaseURL); } The issue is that my getBaseURL gets executed automatically after I have executed the code at least once, but that is the case only in IE. What happens is I call my getUploadURL, I make sure the server sends an event that will result in an Event.COMPLETE, so the getBaseURL gets executed, and the listener is removed. If I call the getUploadURL method and put the wrong path, I do not get an Event.COMPLETE but some other event, and getBaseURL should not be executed. That is the correct behavior in FireFox. In IE, it looks like the load() method does not actually call the server, it jumps directly to the getBaseURL() for the Event.COMPLETE. I checked the willTrigger() and hasEventListener() on _loader before assigning the new URLLoader, and it turns out the event has been well removed. I hope I make sense, I simplified my code. To sum up quickly: in FireFox it works well, but in IE, the first call will work but the second call won't really call the .load() method; it seems it uses the previously stored result from the first call. I hope someone can please help me, Thank you, Rudy

  • how to code client-side call to webservice that calls automatically every few seconds

    I have a webservice that I want to call from the browser every few seconds to see if there are any notification messages in the database that should be displayed on the screen. We have the JSON code working to display the messages in a JavaScript function after an Async Postback, but this only executes after a page turn. I want it to execute every 10-15 seconds as well. A code sample would be very helpful.

  • Crystal Report Function for converting Seconds to Timespan format.

    - by arakkots
    I have a crystal report where it shows the Agent's activities throughout the day with a pie chart. In the details section it is displaying: Activity [string] StartedAt [DateTime] EndedAt [DateTime] Duration [The difference between EndedAt and StartedAt in seconds - Integer] Report data is GroupedBy Activity and summarized by Duration. Currently Duration is shown in seconds but I need to format it 02h:30m:22s:15ms. For that I wrote a custom function in Crystal Report in the Formula Workshop editor as follows, but it looks like the syntax is not right (Error message on keyword Long: "A variable type (for example, 'String') is missing."). Can someone help? Function GetTimeSpanString(seconds as Long) Dim ts As TimeSpan = TimeSpan.FromSeconds( seconds ); GetTimeSpan = string.Format("{0:D2}h:{1:D2}m:{2:D2}s:{3:D3}ms", ts.Hours, ts.Minutes, ts.Seconds, ts.Milliseconds) End Function

  • 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.

  • C# Event Handlers Using an Enum

    - by Jimbo
    I have a StatusChanged event that is raised by my object when its status changes - however, the application needs to carry out additional actions based on what the new status is. e.g If the new status is Disconnected, then it must update the status bar text and send an email notification. So, I wanted to create an Enum with the possible statuses (Connected, Disconnected, ReceivingData, SendingData etc.) and have that sent with the EventArgs parameter of the event when it is raised (see below) Define the object: class ModemComm { public event CommanderEventHandler ModemCommEvent; public delegate void CommanderEventHandler(object source, ModemCommEventArgs e); public void Connect() { ModemCommEvent(this, new ModemCommEventArgs ModemCommEventArgs.eModemCommEvent.Connected)); } } Define the new EventArgs parameter: public class ModemCommEventArgs : EventArgs{ public enum eModemCommEvent { Idle, Connected, Disconnected, SendingData, ReceivingData } public eModemCommEvent eventType { get; set; } public string eventMessage { get; set; } public ModemCommEventArgs(eModemCommEvent eventType, string eventMessage) { this.eventMessage = eventMessage; this.eventType = eventType; } } I then create a handler for the event in the application: ModemComm comm = new ModemComm(); comm.ModemCommEvent += OnModemCommEvent; and private void OnModemCommEvent(object source, ModemCommEventArgs e) { } The problem is, I get a 'Object reference not set to an instance of an object' error when the object attempts to raise the event. Hoping someone can explain in n00b terms why and how to fix it :)
