I have tried searching all of the documentation for something about how to use stopPropagation for 'onclick' in Svelte 5, but can find nothing for it other than the legacy stuff. Is there any way to do this in Svelte 5?

I have tried something like this:

<div onclick|stopPropagation={someFunc}>
    <button onclick={otherFunc}></button>
</div>

But I get this error: "'onclick|stopPropagation' is not a valid attribute name".

How are you supposed to do this in Svelte 5?

I would solve it like this:

<div onclick={(e) => { e.stopPropagation(); someFunc();}}>
    <button onclick={otherFunc}></button>
</div>

Modifiers are not supported for event properties. Either call the respective function in the handler directly, or use a higher order function to wrap the handler.

<script>
  function someFunc(e) {
    e.stopPropagation();
    // [other logic]
  }
</script>

<button onclick={someFunc}>...

<script>
  // extract to a module for reusability
  function stopPropagation(handler) {
    return e => {
      e.stopPropagation();
      handler(e);
    };
  }

  function someFunc() { /* ... */ }
</script>

<button onclick={stopPropagation(someFunc)}>...

(There is more info on this in the migration guide.)
