react-jsx

问题 I've written a gulp task to compile my .jsx and .js scripts into a bundle using watchify and babelify as a transform. For some reason my gulp script seems to be choking on the transform and I'm not sure why: gulp.task('browserify', function() { var bundle = watchify(browserify('./app/jsx/client/index.jsx', { extensions: ['.js', '.jsx'], debug: process.env.NODE_ENV === 'development' })); bundle.transform(babelify); bundle.on('update', function() { rebundle(bundle); }); function rebundle(bundle

问题 I was trying to change background image style dynamically for the following div: Here is my component for changing it, render: function() { var divImage = { backgroundImage : "url(" + this.state.song.imgSrc + "),url(" + this.state.nextImgSrc + ");" }; return ( <li> <div ref="image-pane" className="player" style={divImage}></div> </li> ) } Thanks for the help 回答1: You haven't specified when would you like to change backgroundImage , so I've created version which changes it with onClick : React

问题 I like to send the attribute properties/props/state values from child component to parent component on an event fire onDrag . I could not find proper documentation on this. Here is my code: /*** @jsx React.DOM */ var APP=React.createClass({ getInitialState:function() { return {url:'http://www.youtube.com/embed/XGSy3_Czz8k'} }, handleDrag:function(vidurl) { alert(vidurl); //i need to get child component url here. }, render:function(){ return <div> <VideoFrame src={this.state.url} /> <hr/>

问题 I've made a small fiddle to show the problem: http://jsfiddle.net/4TpnG/582/ When you have an input box with onBlur attached to it, and an initial value from state, input from the keyboard is blocked. When onChange is attached, it's working correctly. Why is this happening and how can this be solved? I would have expected it to accept the characters you type and update the state onBlur. var Test = React.createClass({ getInitialState: function() { return { value: "hallo" }; }, render: function

问题 I am using browserify and watchify , and would like to require() files other than the default extensions .js and .json without specifying the extension, for instance: // Not ideal (tedious) var Carousel = require('./components/Carousel/Carousel.jsx') // Ideal var Carousel = require('./components/Carousel/Carousel') I have tried --extension=EXTENSION as specified in the browserify documentation: "scripts": { "build": "browserify ./src/App.js --transform [ reactify --es6 ] > dist/script.js -v

问题 I've heard of react-templates, but I was still wondering it was possible to make a first-class ForEach component. My end goal is to make something like this more readable: <ul> {list.map(function(item, i) { return <li>{item}</li>; })} </ul> // instead? <ul> <ForEach items="{list}"> <li>{item}</li> </ForEach> </ul> Here's my first serious attempt by passing props: var ForEach = React.createClass({ render: function(){ return ( <ul> {this.props.items.map(function(item, i) { return React.Children

问题 I'm building my React app with Webpack, and css-loader w/modules. I love it. Most of my stylesheets are very small, though, and I'd like to inline them within the same JSX file as my markup and JavaScript. The CSS loader I'm using right now looks like this: { test: /\.(css)$/i, loader: ExtractTextPlugin.extract("style-loader", "css-loader?modules") } In my JSX, I import my separate CSS files like this: import classNames from 'dashboard.css'; ... <div className={classNames.foo}></div>; This is

问题 In _onChange method, I wait for a change in this.state.name . On the change _updateArticle method is called: _onChange() { var team = this.getTeamState(); this.setState({name: team}); console.log(this.state.name); //"Boston Celtics" //this should have changed but it didn't this.unbind("articles"); this._updateArticle(); }, then in _updateArticle a new reference is created using this new state. _updateArticle(team) { var teamRef = new Firebase(this.props.baseUrl + team + "/results"); console

问题 I am new to react.js. Just started learning it. So my question may seems to be stupid but please answer it.
