如何访问名称中有空格的Json Object？ [英] How to access Json Object which has space in its name?

问题描述

在下面查找json回复......

Find below the json response...

{"Object":
          {"PET ANIMALS":[{"id":1,"name":"Dog"},
                          {"id":2,"name":"Cat"}],
           "Wild Animals":[{"id":1,"name":"Tiger"},
                           {"id":2,"name":"Lion"}]
           }
}

在上面提到的回复中，找到PET ANIMALS和野生动物的长度的方法是什么...... ...

In the above mentioned response, what is the way to find the length of "PET ANIMALS" and "Wild ANIMALS"......

推荐答案

var json = /* your JSON object */ ;

json["Object"]["PET ANIMALS"].length // returns the number of array items

使用循环打印数组中的项目数：

Using a loop to print the number of items in the arrays:

var obj = json["Object"];
for (var o in obj) {
    if (obj.hasOwnProperty(o)) {
        alert("'" + o + "' has " + obj[o].length + " items.");
    }
}
