Gossamer Forum: General: Internet Technologies: Firefox won't accept getElementById ?

Hi,

Got a problem with some javascript I've just written :(

It looks like;

Code:
                <script language="JavaScript"> 
                  <!-- Begin 
                  function docheck() { 
                        var isIE = false; 
                        var isNav = false; 
					if (navigator.appName == "Netscape") { 
							isNav = true 
				    	} else { 
						  	isIE = true 
				    	}                     

                        if (isIE) { 
		         		    document.getElementById('loadingdiv').style.display = 'none';  
        				    document.getElementById('downloadit').style.display = 'block';                          
                        } 

                        if (isNav) { 
		         		    document.getElementById('loadingdiv').style.display = 'none';  
        				    document.getElementById('downloadit').style.display = 'block'; 
                        }                         

                        alert("Browser: " + navigator.appName); 

                  } 
                  // End --> 
                </script> 
<body class="body_1col" onload="javascript: docheck()">

Basically, when the page loads... docheck() is run, and decides it its an IE or Mozilla browser.

This part works fine in IE... but not FireFox;

Code:
document.getElementById('loadingdiv').style.display = 'none';  
document.getElementById('downloadit').style.display = 'block';

Anyone got any ideas? (I'm basically trying to make a "loading" div, which gets shown while the page loads, and then dissapears after its finished ... revealing the main div, which has the content in it :)).

TIA
