Currently the render method can only return a single element/component. See: here In the discussion under that ticket some suggest to wrap multiple elements returned from a React component in a HTML comment so that the wrapping component is ignored by the browser, e.g.: <A> <B></B> <Fragment> <C></C> <D></D> </Fragment> <E></E> </A> would render to: <a> <b></b> <!--<fragment data-reactid="">--> <c></c> <d></d> <!--</fragment>--> <e></e> </a> But how to actually create a component that renders just HTML comment? In other words, how the render function of the 'fragment' component in the example

How would I take a string, and convert it to jsx ? For example, if I bring in a string from a textarea , how could I convert it to a React element; var jsxString = document.getElementById('textarea').value; What is the process I would use to convert this on the client? Is it possible? user8296051 You can consider using the JSX attribute dangerouslySetInnerHTML Example usage below: class YourComponent{ render() { someHtml = '<div><strong>blablabla<strong><p>another blbla</p/></div>' return( <div className="Container" dangerouslySetInnerHTML={{__html: someHtml}}></div> ) } } I know is to late

Import React vs Import React, { Component } Which one is better and why? Or does it make no difference other than writing less code later on? Does writing { Component } mean it only imports the Component object? import React, { Component } lets you do class Menu extends Component instead of class Menu extends React.Component . It's less typing and duplication of the React namespace, which is generally a desired modern coding convention. Additionally, tools like Webpack 2 and Rollup do "tree shaking," meaning any unused exports are not bundled into your final code. With import React / React

The site I am developing makes use of Microdata (using schema.org). As we are shifting development over to use React to render our views I have hit a blocker where React will only render attributes in the HTML spec however Microdata specifies custom attributes such as itemscope . As I'm relatively new to React and haven't had chance to fully understand the core just yet, my question is what would be the best way to extend the functionality of react.js to allow for defined custom attributes, e.g., Microdata? Is there a way of extending the attributes/props parser or is it a job for a mixin

I'm beginner of ReactJS. I learned and studied a lot of documents and ebooks on various websites. I realize there are two syntaxes for ReactJS. Example: React.createClass({ displayName: 'Counter', getDefaultProps: function(){ return {initialCount: 0}; }, getInitialState: function() { return {count: this.props.initialCount} }, propTypes: {initialCount: React.PropTypes.number}, tick() { this.setState({count: this.state.count + 1}); }, render() { return ( <div onClick={this.tick}> Clicks: {this.state.count} </div> ); } }); And this version is written by ES6: class Counter extends React.Component

How can I manually trigger a click event in ReactJS ? When a user clicks on element1, I want to automatically trigger a click on the input tag. <div className="div-margins logoContainer"> <div id="element1" className="content" onClick={this.uploadLogoIcon}> <div className="logoBlank" /> </div> <input accept="image/*" type="file" className="hide"/> </div> You could use the ref prop to acquire a reference to the underlying HTMLInputElement object through a callback, store the reference as a class property, then use that reference to later trigger a click from your event handlers using the

In my React component I have a button meant to send some data over AJAX when clicked. I need to happen only the first time, i.e. to disable the button after it's first use. How I'm trying to do this: var UploadArea = React.createClass({ getInitialState() { return { showUploadButton: true }; }, disableUploadButton(callback) { this.setState({ showUploadButton: false }, callback); }, // This was simpler before I started trying everything I could think of onClickUploadFile() { if (!this.state.showUploadButton) { return; } this.disableUploadButton(function() { $.ajax({ [...] }); }); }, render() {

I'm new to React.js, sorry if the question sounds too stupid for you. I'm trying to disable a button when an input field is empty. What is the beest approach in React for this? I'm doing something like the following: <input ref="email"/> <button disabled={!this.refs.email}>Let me in</button> Is this correct? It's not just duplication of dynamic attribute, because I'm also curious about transferring/checking the data from one element to another. You'll need to keep the current value of the input in state (or pass changes in its value up to a parent via a callback function , or sideways , or
