Cannot trigger event ascn.onchange does not exist as a function

Need to trigger the onChange function and pass parameters within it. Here's what I have tried:

 setTimeout(function() { document.getElementById(input.key)?.onchange({}) }, 200);

Encountering the following error message:

 cn.onchange is not a function

Seeking assistance from anyone who can help me resolve this issue.

Answer №1

If you are looking to directly trigger the onchange event,

const input = { key: 'foo' };

// Set up the event handler...
document.getElementById('foo').onchange = (data) => {
  console.log({ data });
};

setTimeout(function() {
  document.getElementById(input.key).onchange({}); // Trigger it...
}, 1000);
<input type="text" id="foo" />
