ReactJS: onClick change element

If I understand your questions correctly, you want to render a different element in case of an “onClick” event.

This is a great use case for react states.

Take the following example

React.createClass({ 
    getInitialState : function() {
       return { showMe : false };
    },
    onClick : function() {
       this.setState({ showMe : true} );
    },
    render : function() {
        if(this.state.showMe) { 
            return (<div> one div </div>);
        } else { 
            return (<a onClick={this.onClick}> press me </a>);
        } 
    }
})

This will change the components state, and makes React render the div instead of the a-tag. When a components state is altered(using the setState method), React calculates if it needs to rerender itself, and in that case, which parts of the component it needs to rerender.
