使用JS在Json中解析嵌套对象
问题描述:
我有这种格式的Json:
I have a Json in this format:
{"year":{"month1":{"date1":{"device1":{"users":6}}}}
示例:
{"2013":{"2":{"5":{"GT-N7000":{"users":1}},"6":{"GT-N7000":{"users":9},"HTC Sensation Z710a":{"users":1}},"7":{"GT-N7000":{"users":15},"HTC Sensation Z710a":{"users":2},"M903":{"users":1}}}}}
如何从Json生成新的用户数组。例如:
How can I generate new arrays of users from the Json. For example:
GT-N7000 = [1, 9, 15]
M903 = [1]
我已尝试嵌套 for
循环,我试过 for..in 循环也是如此。我确信我犯了一个错误。我有什么想法可以过滤/解析这些嵌套的json对象所需的信息吗?
I have tried nested for
loop and I have tried for..in
loop too. I am sure I am making a mistake. Any ideas how I can filter/parse the required information for such nested json objects?
答
我想你会做类似的事情:
I would imagine you would do something like:
var json = {"2013":{"2":{"5":{"GT-N7000":{"users":1}},"6":{"GT-N7000":{"users":9},"HTC Sensation Z710a":{"users":1}},"7":{"GT-N7000":{"users":15},"HTC Sensation Z710a":{"users":2},"M903":{"users":1}}}}};
var result = {}, year, month, date, item;
for (year in json) {
for(month in json[year]) {
for(date in json[year][month]) {
for(item in json[year][month][date]) {
if(item in result) {
result[item].push(json[year][month][date][item].users) // this bit might need editing?
} else {
result[item] = [json[year][month][date][item].users] // this be also might need editing
}
}
}
}
}
