state

问题 I've be fiddling around with ui-router today in trying to better understand the scaffolding in Ionic and one thing that I noticed was that they give the abstracted state of "tabs" a url. The only times I've ever used abstract states, I used an empty string as the url and I notice that if I've ever accidentally attempted to navigate to an abstracted state (as opposed to the child state) I get the error: Cannot transition to abstract state '[insertAbstractStateHere]' edit: "Moreover, in

问题 I am attempting to use the 'File' function in ActionScript 3 to save the following information: I have varying draggable display objects in the scene, the amount and type can vary. I want to save the amount and their position and then load them back in a future session. I am struggling to use File to save anything, I have searched the Adobe documentation and cannot get my head round how to use it. I have not yet developed any code using it. Any help would be appreciated. Thank you. 回答1: You

问题 I have a todo list and want to set the state of that item in the array to "complete" if the user clicks on "complete". Here is my action: export function completeTodo(id) { return { type: "COMPLETE_TASK", completed: true, id } } Here is my reducer: case "COMPLETE_TASK": { return {...state, todos: [{ completed: action.completed }] } } The problem I'm having is the new state does no longer have the text associated of that todo item on the selected item and the ID is no longer there. Is this

问题 I'm starting a new app where I use ActionBarSherlock & HoloEverywhereLib. My min & target SDK are the same (10/2.3.3). This is just so I can also quickly port it to Amazon Kindle & BB10 using the android runtime they have (already used this setup for another app and it worked without issue). All the while the app should have as close to ICS/JB look as possible. For my EditTexts though, I'm giving them a Girgerbread/iOS (round corners, but no shadows) look to them Someone mentioned to me a few

问题 What's the major difference bewteen these two functions? handleOnChange(evt) { this.setState(() => ({ tickerName: evt.target.value })); } handleOnChange(evt) { this.setState({ tickerName: evt.target.value }); } And why with the handleOnChange() function that change the state directly this works fine? <input type="text" value={this.state.tickerName} onChange={(evt) => this.handleOnChange(evt)} /> When I use the first function that change the state with a callback I get this error: TypeError:

问题 I plane to use static variables instead of Application state in ASP.NET and am wondering if this is correct approach: [Global.asax.cs] ... public class Global : System.Web.HttpApplication { void Application_Start(object sender, EventArgs e) { // Code that runs on application startup } ... private static Dictionary<string, object> cacheItems = new Dictionary<string, object>(); private static object locker = new object(); public static Dictionary<string, object> CacheItems { get { lock (locker)

问题 I am a newcomer to WPF, attempting to build a project that follows the recommendations of Josh Smith's excellent article describing The Model-View-ViewModel Design Pattern. Using Josh's sample code as a base, I have created a simple application that contains a number of "workspaces", each represented by a tab in a TabControl. In my application, a workspace is a document editor that allows a hierarchical document to be manipulated via a TreeView control. Although I have succeeded in opening

问题 I'm creating an app where the user can design his own form. E.g. specify name of the field and details of which other columns that should be included. The component is available as a JSFiddle here. My initial state looks like this: var DynamicForm = React.createClass({ getInitialState: function() { var items = {}; items[1] = { name: 'field 1', populate_at: 'web_start', same_as: 'customer_name', autocomplete_from: 'customer_name', title: '' }; items[2] = { name: 'field 2', populate_at: 'web

问题 Following up to: How to write MassTransitStateMachine unit tests? Here's a simple test class (using MS Test) for a simple state machine called ProcedureStateMachine (note: this is not a real production state machine for us... just an experiment I'd used to play around with MassTransitStateMachine a while back.. it seemed a handy self-contained place to experiment with getting unit testing going too): [TestClass] public class ProcedureStateMachineTests { private ProcedureStateMachine _machine;

问题 I'm using protractor framework to test my angular application. Can I check for the angular state in the e2e test? 回答1: Sure, the idea is to use browser.executeAsyncScript() to: locate the element having the ng-app defined initialize the angular.element and get the injector instance get the $state service use $state.current.name to get the current state's name Sample working test using the UI router demo page: describe("Current Angular UI router state", function () { beforeEach(function () {
