Avoiding triggering the parent event from the child in React

Question

Avoiding triggering the parent event from the child in React

I'm facing a situation where clicking on a parent element results in it flipping to display a child element with different colors. However, the issue arises when the user tries to click on one of the colors in the child element, as it also triggers the 'click' event on the parent element.

Is there a way to prevent the event from being triggered on the parent when the child is clicked?

Here are some possible solutions that I'm considering:

Using CSS?
Adding a class pointer-events : none to the parent when the child is clicked. However, this would require removing the pointer-events class from the parent later on.
Utilizing Refs?
Storing the ref of the parent React element and comparing the event.target with the ref when the child is clicked. I have some reservations about this approach due to the global nature of refs.

I would greatly appreciate any thoughts and suggestions for a better solution to the following question: How can I prevent the event from being triggered on the parent when the child is clicked?

Answer №1

One technique you can use is the stopPropagation method.

stopPropagation - This method prevents the current event from further propagating during the bubbling phase.

var App = React.createClass({
  handleParentClick: function (e) { 
    console.log('parent');
  },

  handleChildClick: function (e) {
    e.stopPropagation();
    console.log('child');
  },

  render: function() {
    return <div>
      <p onClick={this.handleParentClick}>
        <span onClick={this.handleChildClick}>Click</span>
      </p>
    </div>;
  }
});

ReactDOM.render(<App />, document.getElementById('root'));

To address this issue, one possible solution is to add the following event callback to the parent:

if(event.target == event.currentTarget){
  event.stopPropagation()
  ....
}

By utilizing this method, you can capture events that stem from the specific attached DOM node while allowing other unrelated events to propagate to the subsequent node.

I needed to trigger a function on props while also preventing event propagation from the child to the parent. Here's how I managed to achieve this:

class LabelCancelable extends Component {

  handleChildClick(e) {
    e.stopPropagation()
  }
  closeClicked(e, props) {
    e.stopPropagation();
    props.onCloseClicked()
  }

  render() {
    const {displayLabel} = this.props;
    return (
      <span className={ "label-wrapper d-inline-block pr-2 pl-2 mr-2 mb-2" } onClick={ this.handleChildClick }>
          <button type="button" className="close cursor-pointer ml-2 float-right" aria-label="Close"
              onClick={(e) => this.closeClicked(e, this.props) }>
              <span aria-hidden="true">&times;</span>
          </button>
          <span className="label-text fs-12">
            { displayLabel }
          </span>
      </span>
    );
  }
}

export default LabelCancelable;

This solution stands out as the most elegant in my opinion. Big thanks to JohnsonFashanu for sharing!

onClick={e => e.currentTarget === e.target && doSomething(e)}

Allow me to elaborate further on this concept: When your mouse initially enters the parent element, the currentTarget is set (event), and later when it moves to the child element, the target changes. Without the check, clicking on the child element may still trigger the parent's onClick event because the mouseleave event has not yet been triggered.

To prevent the click event from reaching the 'child' div and propagating through the children, you can use the following code snippet. Simply place it where you want to stop the click event:

<div onClick={handleClickEvent}> 
 <div onClick={(e) => e.stopPropagation()}>
  <div>
   <p>This will now block the click event</p>
  </div>
 </div>
</div>

When working with JSX files, I found a solution where I simply included

onClick={(e) => e.stopPropagation()

within a specific tag. This action only impacts the child element and not the parent element.

<td>
  {!item.user_info_user ? null : (
    <a
      href={`${ENVIRONMENT.LINK_TO_PROFILE}${item.user_info_user?.domain_url}`}
      target="_blank"         
      rel="noreferrer"
      onClick={(e) => e.stopPropagation()}
    >
      {item.user_info_user?.domain_url}
    </a>
  )}
</td>
