simple text movement via js
html file
    if(!document.getElementById) return false;
    if(!document.getElementById("message")) return false;
    var elem = document.getElementById("message");
    elem.style.position = "absolute";
    elem.style.left = "50px";
    elem.style.top = "100px";
    moveElement("message",200,100,10);
}
 addLoadEvent (positionMessage); 
 the effect you want to achieve is text movement 
, but in fact positiMessage successfully calls 
 but no text movement effect occurs; 
 and the browser reports an error [Web browser] "Uncaught SyntaxError: Unexpected number" (1)
