Here is what i did . // Retrieving the Captcha. WinJS.xhr({ url: "http://example.in/main.aspx", type: "get",

问题 My apologies if the question is overly simple or asking for a bit too much but I feel like I am very close to a simple answer and still too far. All I am trying to do is use the grid layout template in Visual Studio 2012 express to integrate xml data into the grid layout template. I've been really stumped with the winjs.xhr as a means of pulling the xml data. My xml file has nodes to match the group titles, item titles and page content. My partially edited data.js file is below: (function ()

问题 When I leave my WinJS app dormant for a while and then come back to it, and i click on a button, for some reason my calls to my backend aren't working. I get an "Unauthorized" error from the server. How do I modify the invokeApi so that it reauthenticates the user or something? Does anybody have any experience using mobileservices.web.js and how to keep the end user perpetually logged in without having to reauthenticate themselves? Thankyou. client.invokeApi("getTopForumsTotal", { method:

问题 I am trying to add a basic detection script for my application to allow it to display an error message when a call to WinJS.xhr fails. I have every WinHS.xhr call the following function onerror (using the 2nd param of .done() ) and that part is working great. function connectionError() { var msg = new Windows.UI.Popups.MessageDialog("There was a connection error while trying to access online content. Please check your internet connection."); // Add commands and set their CommandIds msg

问题 I am building an app for windows store and I need some default and example data to be in the localstate folder ( Windows.Storage.ApplicationData.current.localFolder ) when the app run the first time. The folder and files structure is a bit complex and I tryed to copy the files at the start of the application, but I can't manage that way. Is it possible to have files being copied automatically from the installation folder to the localstate folder during the store app installation? 回答1:

问题 Iwould like to add a button at the end of a listView in the same way as the bing apps do (see picture for example). I looked for hours in google and in the microsoft documentation but canøt find anything that can give me an idea of how to do this. Did anyone achieved this? thanks 回答1: If you run that app (Health & Fitness), then run Visual Studio and use Debug > Attach to Process, you can open the DOM Explorer and examine how that UI is implemented. What you'll see in this case is that it's

问题 I found this documentation for exporting and saving a Canvas as a png. It gives the following code: var Imaging = Windows.Graphics.Imaging; var picker = new Windows.Storage.Pickers.FileSavePicker(); picker.suggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.picturesLibrary; picker.fileTypeChoices.insert("PNG file", [".png"]); var imgData, fileStream = null; picker.pickSaveFileAsync().then(function (file) { if (file) { return file.openAsync(Windows.Storage.FileAccessMode

问题 I have a recursive function and I am trying to make it run in sequence, returning the promise every time. The code is recursive and works well but works only for the first item in the for loop. Example: folder: 1 - OK folder: 11 - OK folder: 111 - OK folder: 111 - OK folder: 2 - NOT OK folder: 12 - NOT OK All asynchronous downloads completed in sequence. I think it is because when I return the promise from inside, then the for loop gets interrupted. function CopySubFolders(folder, destFolder)

问题 I am trying to find a way to navigate to another html in my app. I tried window.location and WinJS.Navigation.navigate but none works. 回答1: Although you can get document.location and navigation to work (and note that it's document.location, not window.location), the recommended approach is to implement the app like a single-page web application, meaning that you "navigate" by dong DOM replacement inside default.html/index.html. That is, you're page context is always the default HTML page, so

问题 For some reason, my template is not getting used in the binding of data. I'm using Visual Studio's "Navigation App" project type for Windows 8 app. When I run it, each item just gets filled with the full json string. Similar to binding without using any templates at all. home.js : var dataList = new WinJS.Binding.List(); var publicMembers = { itemList: dataList }; WinJS.Namespace.define("VideosData", publicMembers); (function () { "use strict"; WinJS.UI.Pages.define("/pages/home/home.html", {
