toString、toLocaleString的差异比较

var person1 = {
toString:function(){
return "Nikolaos";
},
toLocaleString:function(){
return "Nicholas";
}
};

var person2 = {
toLocaleString:function(){
return "Grigorios";
},
toString:function(){
return "Greg";
}
}
var people = [person1,person2];
alert(person1);//Nikolaos
alert(person2);//Greg
alert(people.toLocaleString());//Nicholas,Grigorios
alert(people.toString());//Nikolaos,Greg
