reactjs-flux

问题 Struggling to find or come up with an elegant answer to this one: If I have multiple dynamic react components that are listening to one flux store to update their child components is it possible to emit changes to specific components rather than emitting changes to all the components that are registered to listen to changes on that store? E.G: A dynamic component has a button and when clicked its tells the flux store to send some data to API. The dynamic component will it update its child

问题 i am using material UI dropdown component and trying to run a callback function only when user fills all the form and submits the form. On the call back function i intend to collect all the form field and generate url to call to api. My problem is that i can not use onChange as stated solution in #560 as i want to collect all the detail only when user clicks the submit button. It is also weird that at the moment, i am able to get value of all the other form element like slider, textfield

问题 I have been stuck on this issue for hours now. I want to implement the Flux architecture. I am trying to create a ToDo list. However, I want to load some initial data before hand. For example in my todoStore.js: import { EventEmitter } from "events"; class ToDoStore extends EventEmitter { constructor(){ super(); this.bucket_list = [{ id: 123, name: "Hi", isCompleted: false }] } getAll(){ return this.bucket_list; } } I have some initial data here which is used by my todo.js : import toDoStore

问题 Is there any reason, other than semantics, to create different dispatch methods for view and server actions? All tutorials and examples I’ve seen (most notably this) ignore the source constant entirely when listening to dispatched payloads in favor of switching on the payload's action type. I suppose there is a reason why this pattern is pervasive in flux examples, but I have yet to see a concrete example as to why this is useful. Presumably one could add an additional if or switch on the

问题 I'm using pouchDB as a local database for an app. I want to query the results from PouchDB and load this into React.js. However, even though I'm using the waitFor() method the results of PouchDB query return too late. I think I don't understand the use of waitFor() correct, maybe someone can shed a light on it. I have two stores, the DbStore that retrieves data from the datbase. And the FileExplorerStore this store is used by my react components. DbStore.dispatchToken = AppDispatcher.register

问题 I am trying to retrieve some data from an API and pass it into my application. Being new to React/Redux however, I am wondering where to make these calls from and how to pass it into my application? I have the standard folder structure (components, reducers, containers, etc.) but I'm not sure where to place my API calls now. 回答1: The easiest way to get started with this is to just add it into your actions, using a function called a thunk along with redux-thunk. All you need to do is add thunk

问题 I have been playing with React/Flux, and I am having trouble wrapping my head around the 'Flux Way' for handling permission-sensitive actions. Overarching question: When a non-logged in visitor attempts an action that requires he/she to be logged in, what is the Flux way of (a) checking if a user is logged in, (b) starting the login flow, (c) finishing the action on success? Take an example of a forum app, that requires users to be logged in to post: We have a comment form component (mostly

问题 I'm a bit stuck thinking on how to implement a reducer where its entities can have children of the same type. Let's take reddit comments as an example: each comment can have child comments that can have comments themselves etc. For simplification reason, a comment is a record of type {id, pageId, value, children} , with pageId being the reddit page. How would one model the reducer around that? I was thinking of having the reducer be a map -> id of the comments where you can filter by page

问题 Here is my form and the onClick method. I would like to execute this method when the Enter button of keyboard is pressed. How ? N.B: No jquery is appreciated. comment: function (e) { e.preventDefault(); this.props.comment({comment: this.refs.text.getDOMNode().value, userPostId:this.refs.userPostId.getDOMNode().value}) }, <form className="commentForm"> <textarea rows="2" cols="110" placeholder="****Comment Here****" ref="text" /><br /> <input type="text" placeholder="userPostId" ref=

问题 I can only see the actual app under /public . The configs in webpack.config.js are below: var path = require('path'); var webpack = require('webpack'); module.exports = { entry: [ 'webpack-dev-server/client?http://localhost:8080', 'webpack/hot/only-dev-server', './app/js/App.js' ], output: { path: path.join(__dirname, 'public'), filename: 'bundle.js', publicPath: 'http://localhost:8080' }, module: { loaders: [ { test: /\.js$/, loaders: ['react-hot', 'babel-loader'], exclude: /node_modules/ }
