javascript将forEach用于嵌套数组

Question

If I have a nested array as follows:

var attendees={attendees :[{name: John},{name: Terry}]}

how do I loop through the names using the forEach function? I have tried:

attendees.forEach(function(attendees){
    console.log(attendees.name):
});

but it does not loop through the subarrays and just gives me:

[{name: John},{name: Terry}]

Appreciate the help!

Answer 1

With another foreach when detects is an array:

attendees.forEach(function(attendee){
   if(attendee.isArray()) {
      attendee.forEach(function(subattendee) {
         console.log(subattendee):
      });
   }
});

Be carefull with the nested variable. You have the same name for de readed array and for the function asigned variable.

Good luck

Answer 2

It should be like this :

var attendees={
attendees : [
    { name: 'John'},
    { name: 'Terry'}
]};



attendees.attendees.forEach(function(attendees){console.log(attendees.name);});
