Show a component on hover in reactjs [closed]

Answer 1

You can use onMouseEnter and onMouseLeave to change the state and render a component conditionally based on the value of the state.

See it in action: https://codesandbox.io/s/XopkqJ5oV

import React, { Component } from 'react';

class HoverExample extends Component {
  constructor(props) {
    super(props);
    this.handleMouseHover = this.handleMouseHover.bind(this);
    this.state = {
      isHovering: false,
    };
  }

  handleMouseHover() {
    this.setState(this.toggleHoverState);
  }

  toggleHoverState(state) {
    return {
      isHovering: !state.isHovering,
    };
  }

  render() {
    return (
      <div>
        <div
          onMouseEnter={this.handleMouseHover}
          onMouseLeave={this.handleMouseHover}
        >
          Hover Me
        </div>
        {
          this.state.isHovering &&
          <div>
            Hovering right meow!
