Get index of selected text inside text input

If you have an HTML element input

, how can you determine the index of the start and end positions of the selected text inside input

? I tried to use window.getSelection

it but it doesn't work correctly. I need to figure this out in an event keydown

.

You can use properties selectionStart

and selectionEnd

to get the indices of the corresponding values.



var start = document.getElementById("myArea").selectionStart;  
var end = document.getElementById("myArea").selectionEnd;

console.log(start);
console.log(end);
