javascript - Issue with getting focus -


i'm trying change img if user clicks anywhere inside specified div element. nothing happening, know must wrong.

so far have this

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';      }  }
<div style="border-style: solid;height:20px;" id="demo"></div>    <img id="pic1" src="https://pbs.twimg.com/profile_images/688766010837446657/2dgfpaq6.png">

not sure if i'm getting right you're trying do. can see working code here :

you had typos in code , missed parenthesis if condition 

var demo = document.getelementbyid('demo');  demo.addeventlistener('click', myfunction, false);    function myfunction() {      if (document.getelementbyid("demo") === document.activeelement) {      document.getelementbyid('pic1').src = 'https://pbs.twimg.com/profile_images/701853789855346689/ikxiygko.png';    } else {      document.getelementbyid('pic1').src = 'https://screenshots.fr.sftcdn.net/fr/scrn/76000/76818/microsoft-small-basic-22.jpg';    }  }
<div style="border-style: solid;height:20px;" id="demo"></div>    <img id="pic1" src="https://pbs.twimg.com/profile_images/688766010837446657/2dgfpaq6.png">
