How to get id of button inside main div when I clicked on button?

April 25, 2023

I have added onclick on main div. Whenever I click on its child elements, main div onclick is trigger. I cannot get id of the child element I clicked inside the main div using this.

Here is sample

<div id = 'main' onclick='console.log(this);'>
  <p> some paragraph </p>
  ...
  <button id='test' type="button">click</button>
</div>

>Solution :

You can create a function by passing the event. Then use event.target to get the id.

Demo:

<div id = 'main' onclick='handleClick(event);'>
  <p> some paragraph </p>
  
  <button id='test' type="button">click</button>
</div>

<script>
  function handleClick(event) {
    console.log(event.target.id);
  }
</script>
