Property 'files' does not exist on type 'EventTarget' error in typescript

Question

I am trying to access the value of the input file from my ionic 2 application but still I\'m facing the issue of property files does not exist on type \'EventTarget\'. As it

Answer 1

The simplest solution is to declare e as any

e.g

document.getElementById('customimage').onchange = (e: any) => {
    let files = e.target.files[0];
    ...
};

But you lose type information. A safer approach might be to declare your own FileEvent type based on https://developer.mozilla.org/en-US/docs/Web/API/FileReader/onload.
