React Scrollspy - API

In this section you will find advanced information about the Scrollspy component. You will learn which modules are required in this component, what are the possibilities of configuring the component, and what events and methods you can use in working with it.

Import statement

React scrollspy can use other components, like ListGropu or Navbar in addition to present current scroll location, so rememeber about proper imports.

Main Scrollspy components:

        
            
            import { MDBScrollspyBox, MDBScrollspyList, MDBScrollspyListItem, MDBScrollspyText  } from "mdbreact";

Import statement

In order to use Scrollspay you have to define scrollable container, and sections inside of it and determine which section is visible.

Our suggestion is to use React ref to watch it's offsetTop property. Then we compare it with offsetTop of nested sections to determine which is active.

Also rememeber that Scrollspy elements (sections and navigation) have to be wrapped inside MDBScrollspyBox and sections have to be inside MDBScrollspyTex.

Sample code looks like this: 

        
            
          import React from "react";
          import ReactDOM from 'react-dom';
          import {
            MDBScrollspyBox,
            MDBScrollspyList,
            MDBScrollspyListItem,
            MDBScrollspyText
          } from "mdbreact";
          import DocsLink from "../DocsLink";

          class ScrollSpyPage extends React.Component {
          constructor(props) {
            super(props);
            this.state = {
              active: 0,
              sections: []
            };

            this.scrollSpyText = React.createRef();
          }

          componentDidMount() {
            let sections = this.scrollSpyText.current.getElementsByTagName("h4");
            this.setState({ sections });
          }

          handleScroll = (e) => {
            const scrollTop = e.target.scrollTop;
            const sections = this.state.sections;
            const lastIndex = sections.length - 1;

            for (let i = 0; i < lastIndex; i++) { if ((scrollTop> sections[i].offsetTop - 20) && (scrollTop < sections[i +
              1].offsetTop - 20)) { this.setState({ active: i }); } }; if (scrollTop> sections[lastIndex].offsetTop - 20)
              this.setState({ active: lastIndex });
          }

          render() {
            return (
              <MDBScrollspyBox>
                <MDBScrollspyList>
                  <MDBScrollspyListItem href="#section1" active={this.state.active===0}>

                  </MDBScrollspyListItem>
                  <MDBScrollspyListItem href="#section3" active={this.state.active===2}>
                    section3
                  </MDBScrollspyListItem>
                </MDBScrollspyList>
                <MDBScrollspyText onScroll={this.handleScroll} scrollSpyRef={this.scrollSpyText}>
                  <div id="section1">section1</div>
                  <div id="section2">section2</div>
                  <div id="section3">section3</div>
                </MDBScrollspyText>
              </MDBScrollspyBox>
            );
          }
        }

        export default ScrollSpyPage;
