Trying to Create Homepage with Random Background Image Each Time it is Accessed. Using HTML and JavaScript. What am I doing wrong? -

-

i'm trying make array of multiple background images , having browser choose 1 @ random display.

i have attempted coding don't know i'm going wrong.

here code working with

<head> <meta charset="utf-8"> <title>christopher tameji foose</title> <script src="chrisfoose.js">  var imgsrcarr = ["/background/000.jpg", "/background/001.jpg", "/background/003.jpg"]      window.onload = function() {             var randnum = math.floor(math.random() * 3);         console.log(randnum);   document.getelementbyid("main").style.backgroundimage = "url('" + imgsrcarr[randnum] + "')";         }  </script> <link rel="stylesheet" href="stylesheet.css">      ;<script>      ;</script>

a zip of website @ https://www.sendspace.com/file/2la4he. feedback appreciated.

you have couple of issues here. first, document.getelementbytagname("div.main") invalid since there no function called "getelementbytagname" want "getelementsbytagname" (notice "s").

second, target div has id, rather looping through tags , selecting 1 want, use getelementbyid() instead.

var imgsrcarr = ["/background/000.jpg", "/background/001.jpg", "/background/003.jpg"] window.onload = function() {     var randnum = math.floor(math.random() * 3);     document.getelementbyid("main").style.backgroundimage = "url('" + imgsrcarr[randnum] + "')";
