If you want to know the index position of an SVG element in a collection, such as the SVG itself or a group, here the solution:

elements.on('click', function(e, d){
  
    const list = [...this.parentNode.children]
    const index = list.indexOf(this)
    console.log(index)
  
})

Here a live example.
