Input List Selection Changed Event

Issue

I have this example:

<datalist id="browsers">
  <option value="Internet Explorer">
  <option value="Firefox">
  <option value="Google Chrome">
  <option value="Opera">
  <option value="Safari">
</datalist>

I need to catch an event, when the user selects option (with mouse or keyboard).

I tried to do onchange="MySuperFunction();", but this works only when an item is selected and then the list is unfocused.

Solution

The input event should work for what you need. As I understand, you can't use a datalist directly, but it is connected to an input by the list attribute. This event binding would go on that input:

document.getElementById('browsers-input').addEventListener('input', function (event) {
   if (event.inputType == 'insertReplacementText')
       console.log('autocomplete option selected'); 
});
