javascript document.write variables

I'm writing a simple javascript with several document.write statements...

String accountLink = "#";
String accountLogo = "img/myLogos/someLogo.png";

function drawLogos(){
    document.write('<li><a href="');
    document.write("#");  // link to account page
    document.write('"><img src="');
    document.write('img/myLogos/someLogoF.png'); // reference to logo image
    document.write('" alt=""  /></a></li>');
}

Which works just fine. but when I use a variable like this...

document.write(accountLink);

it doesn't load anything. I've tried getting rid of the quotes but nothing different happens. Is there some small syntax error I'm not picking up on?

You should initialize variable instead of String using var and then try:

var mytext = "Hello again";
document.write(mytext);

Here is working demo

use var instead of String, Javascript is a weak typing language

<script>
        var accountLink = "#";
        var accountLogo = "img/myLogos/someLogo.png";

        function drawLogos(){
            document.write('<li><a href="');
            document.write(accountLink);  // link to account page
            document.write('"><img src="');
            document.write(accountLogo); // reference to logo image
            document.write('" alt=""  /></a></li>');
        }
</script>

Declare your string variables with var 

  var accountLink = "#";
document.write(accountLink);
