React Bootstrap waves effect is an impression of circular overlay movement, triggered by clicking the object, flowing from the center of the click. By default, waves are added to buttons, masks, and navbar's links as in examples below.

Example

Click me

Show code

        
            
        import React from "react";
        import { MDBBtn, MDBCardImage } from "mdbreact";

        const WavesPage = () => {
          return (
            <div>
              <MDBBtn color="primary">Click me</MDBBtn>

              <MDBCardImage
                className="img-fluid"
                src="https://mdbootstrap.com/img/Photos/Horizontal/Nature/6-col/img%20(54).webp"
                waves
              />
            </div>
          );
        }

        export default WavesPage;

Customization

You can add waves effect to any element. The Waves component requires object with cursor's time and position. We will have to set up a function and store the cursor information in state.

Show code

        
            
        import React from "react";
        import { MDBWaves } from "mdbreact";

        class CustomComponent extends React.Component {
          constructor(props) {
            super(props);
            this.state = {
              cursorPos: {}
            };
          }

          handleClick = e => {
            e.stopPropagation();
            // Waves - Get Cursor Position
            let cursorPos = {
              top: e.clientY,
              left: e.clientX,
              time: Date.now() // time indicates particular clicks
            };
            this.setState({ cursorPos: cursorPos });
          };

          render() {
            return (
              <div
                onMouseUp={this.handleClick}
                onTouchStart={this.handleClick}
              >
                <img src="https://mdbootstrap.com/img/Photos/Horizontal/Nature/6-col/img%20(54).webp" />
                <MDBWaves
                  cursorPos={this.state.cursorPos}
                />
              </div>
            );
          }
        }

        export default CustomComponent;
