Ways to exclusively trigger the onclick function of the primary button when dealing with nested buttons in React.js

Question

Ways to exclusively trigger the onclick function of the primary button when dealing with nested buttons in React.js

Let me elaborate on this issue. I have a List component from material-UI, with ListItem set to button=true which makes the entire item act as a button.

Within the ListItem, I have added a FontAwesomeIcon. To hide the button, I set its style to visibility: "hidden" and the Icon to visibility: "visible" so that it remains visible. (perhaps not the best practice, but couldn't think of another way at the moment).

Now, when someone clicks on the ListItem outside the Icon area, the onClick event of the ListItem is triggered - which is expected and good! However, when clicking on the Icon itself, both the onClick events of the "Icon button" and the ListItem are called - while this behavior is expected, it's not desired in my case.

Is there a way to bring the smaller "nested" button to the forefront of the parent button so that only its event is triggered?

If not, is there a way for the parent onClick event to detect whether it was clicked within the Icon area so that different functions can be called based on the click location?

I am open to any other suggestions as I am new to react and web development in general, and I want to learn and implement best practices solutions.

Thank you in advance :)

This relates to handling events in JavaScript. You can utilize the event.stopPropagation() method to prevent an event from propagating up the DOM tree. Learn more about event.stopPropagation() here.

Check out this React example below:

import React from "react";
import "./styles.css";

export default function App() {
  const parentButtonHandler = () => {
    console.log("parent");
  };
  const childButtonHandler = (e) => {
    console.log("child");
    e.stopPropagation();
  };

  return (
    <div className="App">
      <button onClick={parentButtonHandler}>
        Hello CodeSandbox
        <button onClick={childButtonHandler}>
          Start editing to see some magic happen!
        </button>
      </button>
    </div>
  );
}

It seems like the issue you're experiencing is due to event bubbling. For more detailed information, check out this resource: https://javascript.info/bubbling-and-capturing A possible solution is to utilize event.stopPropagation() within the click event handler for the "Icon button", preventing the event from bubbling up to the ListItem parent element.

Using nested buttons in your layout may not be the best idea as it can make it harder to support and result in a messy design.

If you're looking for alternative approaches, consider the following options:

Having two separate buttons within your ListItem component

export const Comp = () => {
  return (
   <ListItem>
    <button onClick={handleOnMainClick}>mainButton</button>
    <button onClick={handleOnSecondClick}>secondButton</button>
   </ListItem>
  )
}

This method works well if your buttons are meant to be on either the left or right side only.

If you need to position your functional button anywhere on the screen, you can use CSS positioning

export const Comp = () => {
  return (
   <ListItem styles={{position: 'relative'}}>
    <button onClick={handleOnMainClick}>mainButton</button>
    <button 
      styles={{position: 'absolute', top: '50%', left: '50%'}} 
      onClick={handleOnSecondClick}>
         secondButton
     </button>
   </ListItem>
  )
}
