javascript - KineticJS enumerate data types of an Object -

the code below enumerate properties of object, can data types enumerated?

function enumerateattributes(node){     var text="";     var attrs=circle1.getattrs();     (key in attrs) {         if (attrs.hasownproperty(key)) {             text+=(key+"=="+attrs[key]+"\n");         }     }     alert(text); } 

for javascript data types can use typeof: console.log(typeof attrs[key]);

these common types returned:

• null,

• object,
• boolean,
• number,
