##Have a look at it!
In App.js We created a class named Components
ReactDOM.render(<Componets />, document.getElementById('root'));
This will render our class which contains all our elements
<textarea class="form-control"
onChange={this.htmlChange}
rows="20"
placeholder="Cool stuff goes here">
</textarea>
You can see There is a method onChange which is bound to htmlChange which is bound to a state change
htmlChange = (event) => {
this.setState({html: event.target.value});
}
Which changes the state of html. Similarly is done for css and js.
componentDidMount() {
this.interval = setInterval(() => this.setState({ framesrc:"<html>"+"<style>"+this.state.css+"</style><script>"+this.state.js+"</script>"+this.state.html+"</html>" }), 350);}
ComponentDidMount will execute on every change state and combine our code from 3 text areas to one state framesrc. We will use an iframe element to render html source
<iframe width="100%" height="100%" srcDoc={this.state.framesrc}></iframe>
srcDoc has a state of framesrc and hence it will automatically change.
