javascript - JSON 对象键值

Question

这是我来自服务器的 JSON 响应

{    "responses": 
              {        
                 "army":[{"name":"jhon","age":"32"},{"name":"sam".....}]      
                 "navy":[{"name":"tom","age":"42"},{"name":"josh"......}]   
                 "air":[{"name":"jhona","age":"34"},{"name":"samy"........}]   
               }  
}

我试过:

var obj1= myArrays.responses; 
for (var key1 in obj1) { 
    console.log(key1); 
    for (var i = 0; i < obj1.length; i++) { 
        console.log(obj1.length);
    }
}

我希望输出看起来像这样，但我不知道该怎么做。

In army, jhon(age:32), sam(age:35)
In navy, tom(age:42), josh(age:35)
In air, jhona(age:34), samy(age:35)

Answer 1

只是循环:

var output = '';
for (var branch in responses) {
    ouput += 'In ' + branch + ', ';
    var people = responses[branch];
    for (var i = 0; i < people.length; i++) {
       output += people[i].name + '(age:' + people[i].age +')';
    }
}

根据您添加的代码，您缺少一个分配:

var obj1= myArrays.responses; 
for (var key1 in obj1) { 
    console.log(key1); 
    var people = obj1[key1]; // get the people array
    for (var i = 0; i < people.length; i++) { 
        console.log(people[i].name, people[i].age); 
    } 
}
