testen ob "element has no properties"

[Christian Kruse]

你好 Kermit,

element has no properties
if ( element.offsetTop != null ) {
dein Beispiel funz also nicht.

Du hast es falsch angewendet:

  
cumulativeOffset: function(element) {  
     var valueT = 0, valueL = 0;  
  
     if(element == null) return;  
  
     do {  
       valueT += element.offsetTop  || 0;  
       valueL += element.offsetLeft || 0;  
       element = element.offsetParent;  
     } while (element);  
     return Element._returnOffset(valueL, valueT);  
   }  

再见,
