Show or hide element in React

Show or Hide Element in React: A Simple Guide 👀✨

So, you're using React.js for the first time and want to show or hide an element on your page whenever a click event occurs. No worries, my friend, I've got you covered! In this guide, I'll walk you through the process of achieving this using React.

The Problem 🤔

Imagine you have a button, and whenever it's clicked, you want to show or hide a specific element on your page. In this case, you want to show the "results" div when the click event fires.

Based on the code snippet you provided, you're on the right track! We just need to make a couple of tweaks.

The Solution 💡

Here's what you can do to accomplish your goal:

1. First, let's define a state property within your Search component to keep track of whether the results should be shown or hidden. We'll call it showResults and initialize it as false. Your Search component should look like this:

var Search = React.createClass({
  getInitialState: function() {
    return {
      showResults: false,
    };
  },

  handleClick: function() {
    this.setState({ showResults: !this.state.showResults });
  },

  render: function() {
    return (
      <div className="date-range">
        <input
          type="submit"
          value="Search"
          onClick={this.handleClick}
        />
        {this.state.showResults && <Results />}
      </div>
    );
  },
});

1. In the above code, we've added a new condition ({this.state.showResults && <Results />}) within the render method. This condition checks if showResults is true, and if so, it renders the Results component.

2. Lastly, we need to update the Results component to reflect the changes. It should remain the same:

var Results = React.createClass({
  render: function() {
    return (
      <div id="results" className="search-results">
        Some Results
      </div>
    );
  },
});
