I'm trying to change the img if the user clicks anywhere inside the specified div element. Nothing is happening, i know something must be wrong.

So far i have this

```js
setInterval("myFunction()", 1);

function myFunction() {

    if document.getElementById("demo").hasFocus; {
        document.getElementById('pic1').src='https://pbs.twimg.com/profile_images/701853789855346689/iKxIyGkO.png';
    } else {
        document.getElementById('pic1').src='https://pbs.twimg.com/profile_images/688766010837446657/2DgfpAQ6.png';
    }
}
```

```html
<div style="border-style: solid;height:20px;" id="demo"></div>

<img id="pic1" src="https://pbs.twimg.com/profile_images/688766010837446657/2DgfpAQ6.png">
```
