Angular 4 On select change get attribute data value

Answer 1

As your attr.data-some-data value is the same as value you can simply write:

console.log(event.target.value);

But if you really want to get that data-attribute then use the following code:

const selectEl = event.target;

const val = selectEl.options[selectEl.selectedIndex].getAttribute('data-somedata');
// or
const val = selectEl.options[selectEl.selectedIndex].dataset.somedata;
