    react.JS - hide/show component

    Hello

    I am new to reactJS.

    I wonder if it is possible to hide/show components "onclick"? For example: index.php shows some text in headings and paragraphs(a component), a button or link can be found under the text. if the link or button is clicked, the text will change(new headings and paragraphes, aka a new component). How can this be done?

    Short answer, in your onclick handler, call setState. The headings and paragraphs you show could come from the state, so when you change the state, then your DOM automatically re-renders.

    Here's an example from the React tutorial:

    Code:
    class Square extends React.Component {
      constructor(props) {
        super(props);
        this.state = {
          value: null,
        };
      }
    
      render() {
        return (
          <button className="square" onClick={() => this.setState({value: 'X'})}>
            {this.state.value}
          </button>
        );
      }
    }
    for(split(//,'))*))91:+9.*4:1A1+9,1))2*:..)))2*:31.-1)4131)1))2*:3)"'))
    {for(ord){$i+=$_&7;grep(vec($s,$i++,1)=1,1..($_>>3)-4);}}print"$s\n";
