winjs

问题 I have a WinJS project and I receive toasts notification from my webservice. In my webservice my XML is like: string type = "Computer"; string toast1 = "<?xml version=\"1.0\" encoding=\"utf-8\"?> "; string message = "{\"Message\":{\"Id\":\"6724d22a-87fe-4137-b501-9d9a9a0558b1\",\"DetailId\":\"dc02e784-7832-4625-a538-29be7f885ccb\",\"Description\":\" Message\",\"UserName\":null,\"ActionDateTime\":\"2015-09-15T15:36:14+05:45\",\"CalamityId\":\"c0fa848e-ee6c-4b91-8391-a12058f25387\",\

问题 I have a save function in my app which can be called manually and an autosave function which runs every 60 seconds. To prevent the two ops trying to access the same file at the same instant, I set a flag called isSaving to true when one starts running, and to false again afterward. If open or save detect that autosave is running, they wait 1000ms and try again. If they fail after that I consider it an error. Autosave: setInterval(autosave, 1000 * 60); isSaving = false; function autosave() {

问题 Scenario I need a background upload queue that sends files to a server. The queue should send the files in sequential order as they are pushed into the queue (FIFO). My solution var pendingFiles = []; var filesOperation = null; uploadNextAsync = function(file) { var next; if (!pendingFiles.length) { return WinJS.Promise.as(); } next = pendingFiles.shift(); fileslogger.debug("Uploading " + next); return fileQuery.folder.getFileAsync(next).then(function(file) { return Server.sendFileAsync(file)

问题 How can I tell using c# or winjs when your app that the user downloaded is being uninstalled? Can you call home, or try to save the client by giving/redirecting them to a site with an exit poll? 回答1: Not supported. A key goal with the Windows Store is to make it seamless and painless for consumers to try apps. One result of this is that Store apps don't have any control over or hooks into install/uninstall processes. Bottom line is that the act of uninstall is not a time to try to exercise

问题 Is it possible to bind a List-Binding to a HTML Select () element to display the contents of the binding as elements? Im using this right now, which doesn't seem to work: <select data-win-options="{itemDataSource: ...)}"></select> 回答1: There is a programmatical way without declarative binding: JavaScript part: // Load data var options = [ { optionValue: 1, optionText: 'One', selected: false }, { optionValue: 2, optionText: 'Two', selected: true }, { optionValue: 3, optionText: 'Three',

问题 I know it's possible to call native C# from WinJS by creating a Windows Runtime Component and then adding it as a reference to the WinJS app -- but is it possible to do the same thing from the WinJS app when it's loaded inside a WebView ? I've tried it, but it seems the WinJS app inside the WebView is operating in a completely different context or something and isn't finding the symbols, so it crashes and offers to launch a new instance of VS2013 to try and debug. 回答1: You're correct in that
