In React dangerouslySetInnerHTML is not working for html tags.

Question

In React dangerouslySetInnerHTML is not working for html tags. it is not even working on homepage of React . Type <h1>this is heading.</h1>

How can i render html tags in React? Why did we pass * for <em> tags in React tutorials ?

Answer 1

On React homepage example they use markdown ( markdown does not understand HTML syntax) and library Remarkable ., if you want to use only HTML remove Remarkable from rawMarkup method - { __html: this.state.value }

 var HTMLEditor = React.createClass({ getInitialState: function() { return {value: 'Put here <h1>HTML</h1>'}; }, handleChange: function(e) { this.setState({ value: e.currentTarget.value }); }, markup: function() { return { __html: this.state.value }; }, render: function() { return ( <div className="html-editor"> <textarea onChange={ this.handleChange } defaultValue={this.state.value} /> <div className="html-editor__content" dangerouslySetInnerHTML={ this.markup() } /> </div> ); } }); ReactDOM.render(<HTMLEditor />, document.getElementById('container')); 

 .html-editor { border: 1px solid #000; padding: 10px; } .html-editor__content { margin: 10px 0 0 0; }
