Adding images to an HTML document with JavaScript

I've tried some HTML DOM code from several sites, but it isn't working. It isn't adding anything. Does anyone have a working example on this?

this.img = document.createElement("img");
this.img.src = "img/eqp/"+this.apparel+"/"+this.facing+"_idle.png";
src = getElementById("gamediv");
src.appendChild(this.img)

But it isn't adding anything to the div gamediv. I've tried document.body as well, with no result.

Thanks in advance.

Solution 1:

You need to use document.getElementById() in line 3.

If you try this right now in the console:

var img = document.createElement("img");
img.src = "http://www.google.com/intl/en_com/images/logo_plain.png";
var src = document.getElementById("header");
src.appendChild(img);

<div id="header"></div>

... you'd get this:

With a little research i found that javascript does not know that a Document Object Exist unless the Object has Already loaded before the script code (As JavaScript reads down a page).

<head>
    <script type="text/javascript">
        function insert(){
            var src = document.getElementById("gamediv");
            var img = document.createElement("img");
            img.src = "img/eqp/"+this.apparel+"/"+this.facing+"_idle.png";
            src.appendChild(img);
        }
     </script>
 </head>
 <body>
     <div id="gamediv">
         <script type="text/javascript">
             insert();
         </script>
     </div>
 </body>

Solution 3:

This works:

var img = document.createElement('img');
img.src = 'img/eqp/' + this.apparel + '/' + this.facing + '_idle.png';
document.getElementById('gamediv').appendChild(img)

Or using jQuery:

$('<img/>')
.attr('src','img/eqp/' + this.apparel + '/' + this.facing + '_idle.png')
.appendTo('#gamediv');
