解析在角控制器JSON数据 [英] parse json data in angular controller
问题描述
我用 $ http.get
得到这个JSON数据,做这样的分配 $ scope.a = data.a
,如何访问X - 当我打印 A
控制台就说明 [对象的对象],[对象的对象]
,应该不会是 [对象对象对象],[对象对象对象]
?当我使用 $ scope.a [0] .X [0]
,它说不确定。任何想法如何解决呢?
{
一个: [{
×:1385118661279,
Y:{
Y1:25,
Y2:12
},
Z:[
{
Z1:20
},
{
Z2:23
}
]
},
{
×:1385118650279,
Y:{
Y1:25,
Y2:32
},
Z:[
{
Z1:21
},
{
Z2:22
}
]
}], B:文本
}
[对象的对象],[对象的对象]
意味着它是一个对象数组。括号上述不引用数组,它只是意味着它是一个对象。
有关您的下一个问题,嵌套的'X'是不是数组。您可以通过访问:
$ scope.a [0] .X
I get this json data by $http.get
and did the assigning like this $scope.a = data.a
,how to access x? when I print a
in console it shows [object Object],[object Object]
, shouldn't it be [object Object Object],[object Object Object]
? And when I use $scope.a[0].x[0]
, it says undefined. Any idea how to solve it?
{
"a": [{
"x":1385118661279,
"y":{
"y1":25,
"y2":"12"
},
"z":[
{
"z1":20
},
{
"z2":23
}
]
},
{
"x":1385118650279,
"y":{
"y1":25,
"y2":"32"
},
"z":[
{
"z1":21
},
{
"z2":22
}
]
}],
"b": "text"
}
[object Object],[object Object]
means it is an array of objects. the brackets above does not refer to array, it simply means it is an object.
For your next question, the nested 'x' is not an array. You can access it by:
$scope.a[0].x
