javascript - jquery 对象属性值平均值

Question

我有以下对象:

rating {
     atmosphere: 85
     cleanliness: 91
     facilities: 91
     staff: 85
     security: 94
     location: 78
     valueForMoney: 85
    }

如何获得所有属性值的平均总和？

  $.each( json.rating, function( key, value) {
    console.log( key + ": " + value);

  });

Answer 1

没有 jquery 函数。你必须手动完成

var count = 0;
var sum = 0;
$.each(rating, function(k, v){
   count++;
   sum += v;
});

var average = sum / count;
