如何让for in循环只遍历对象的属性而不遍历方法

Question

以下代码把对象实例的方法也遍历了，我的问题如题。function member(sName,sGender,iAge,sProfession){
this.name = sName;
this.sex = sGender;
this.age = iAge;
this.job = sProfession;
}
member.prototype.showMemberInfo = function(obj){
for(var i = 0 in obj){
alert(i + ": " + obj[i]);
}
}
var LDH = new member("刘德华","男",45,"艺人");
LDH.showMemberInfo(LDH);

Answer 1

if(typeof(obj[i])=="function"){
continue;
}
试试

Answer 2

加个typeof  类型判断 for(var i = 0 in obj){
                   if(typeof(obj[i])!="function"){
                         alert(i + ": " + obj[i]);
                     }
                    
        }

Answer 3

if (typeof(obj[i]) != 'function') alert(i + ": " + obj[i]);
