How do you teach Vue to handle events when…

In Vue, you cannot directly handle events on elements with pointer-events: none because they do not participate in mouse and touch event handling. Alternative approaches include:

Passing the event to a parent element: Place a non-interactive element inside a parent that listens for events and delegates them.

<template>
  <div @click="handleEvent">
    <div style="pointer-events: none;">Non-interactive element</div>
  </div>
</template>

<script>
export default {
  methods: {
    handleEvent(event) {
      // Logic to handle the event, e.g., based on event.target
      console.log('Event caught on parent', event.target);
    }
  }
}
</script>

Using an overlay: Place an interactive, transparent element over the non-interactive one.

<template>
  <div style="position: relative;">
    <div style="pointer-events: none;">Non-interactive element under overlay</div>
    <div style="position: absolute; top: 0; left: 0; width: 100%; height: 100%; background: rgba(0,0,0,0); cursor: pointer;" @click="handleOverlayClick"></div>
  </div>
</template>

<script>
export default {
  methods: {
    handleOverlayClick() {
      // Logic to handle overlay click
      console.log('Click on transparent overlay');
    }
  }
}
</script>

Programmatic simulation of events: Use JavaScript to determine cursor or touch position and invoke the corresponding logic, simulating event handling. This method is more complex and requires precise calculation of element positions.

// Example pseudocode for detecting a click on a non-interactive element
document.addEventListener('click', function(event) {
  const element = document.getElementById('my-non-interactive-element');
  const rect = element.getBoundingClientRect();

  if (event.clientX >= rect.left && event.clientX <= rect.right &&
      event.clientY >= rect.top && event.clientY <= rect.bottom) {
    console.log('Programmatically detected click on non-interactive element');
    // Your handling logic
  }
});

The choice of method depends on the specific task and DOM structure. Passing the event to a parent element is often the simplest and most preferred approach.
