访问对象的数组JSON(JavaScript的)
问题描述:
可能重复:结果
I有一个嵌套的数据结构/ JSON,我怎么可以访问特定的值?
我有一个JSON数组返回嵌套对象的一项服务。哪能遍历对象和打印所需的数据?
I have a service that returns nested Objects in a JSON Array. How can I loop through the objects and print the desired data?
这是我的结果:
[
{
"item1": {
"sourceUuid": "5599ffac-4b99-47c7-9370-a25e7e465429",
"targetUuid": "5599ffac-4b99-47c7-9370-a25e7effffff"
}
},
{
"item2": {
"sourceUuid": "bf63fe50-8b2b-488d-b565-009fcaebdb45",
"targetUuid": "-1"
}
},
{
"item3": {
"sourceUuid": "0005fd96-f654-4781-8602-09fedc0cdd35",
"targetUuid": "0005fd96-f654-4781-8602-09fedc0cdd35"
}
}
]
这是我想打印每个项目的内容(项目1,项目2,项目3,...):
This is what I want to print for each item (item1, item2, item3, ...):
Item Name: item1
Source: 5599ffac-4b99-47c7-9370-a25e7e465429
Target: 5599ffac-4b99-47c7-9370-a25e7effffff
到目前为止,我尝试:
So far I tried:
for (var i = 0, length = data.length; i < length; i++) {
for (obj in data[i]) {
console.log(obj);
}
}
这仅返回ITEM1,ITEM2等,但我不知道如何访问sourceUuid等在那里。
This only returns "item1", "item2" etc. But I don't know how access sourceUuid etc. from there
答
您可以循环使用的 for循环并与为对象的属性-in循环的。
You can loop the array with a for loop and the object properties with for-in loops.
for (var i=0; i<result.length; i++)
for (var name in result[i]) {
console.log("Item name: "+name);
console.log("Source: "+result[i][name].sourceUuid);
console.log("Target: "+result[i][name].targetUuid);
}
