Javascript AngularJS和JSON数组

我试图通过使用AngularJS过滤器（如$filter）来安排现有的JSON数组，如下所示，但失败了

 {
        {       
            name: "name 1",         
            label: "A",     
        },
        {       
            name: "name 2",         
            label: "A",     
        },
        {       
            name: "name 3",         
            label: "B",     
        },
        {       
            name: "name 4",         
            label: "B",     
        },
        {       
            name: "name 5",         
            label: "B",     
        },
        {       
            name: "name 6",         
            label: "C",     
        },
        {       
            name: "name 7",         
            label: "C",     
        },
        {       
            name: "name 8",         
            label: "C",     
        },
        {       
            name: "name 9",         
            label: "D",     
        }
    }

我想要的是将这个数组排列成如下的新数组

{
    "A" : { 
        {       
            name: "name 1",         
            label: "A",     
        },
        {       
            name: "name 2",         
            label: "A",     
        },
    },
    "B" : {
        {       
            name: "name 3",         
            label: "B",     
        },
        {       
            name: "name 4",         
            label: "B",     
        },
        {       
            name: "name 5",         
            label: "B",     
        },
    },
    "C" : {
        {       
            name: "name 6",         
            label: "C",     
        },
        {       
            name: "name 7",         
            label: "C",     
        },
        {       
            name: "name 8",         
            label: "C",     
        },
    },
    "D" : {
        {       
            name: "name 9",         
            label: "D",
        }
    }   
}

如何使用angularJS获取新数组？

如果您正在使用，您可以使用

\uuux.groupBy

函数来实现此目的：

var grouppedArray = _.groupBy(myArray, function(i){
  return i.label;
})

若要仅提取标签，您可以像这样进行smth

var uniqueLables = [];
angular.forEach(myArray, function(obj){
  if(uniqueLables.indexOf(obj.label) == -1) uniqueLables.push(obj.label)
})

试试这个

   var result = {}
   angular.forEach(jsonData, function(obj){
       if(!result.hasOwnProperty(obj.label) result[obj.label] = []
       result[obj.label].push(obj)
   })

   console.log(result)

非常感谢。再帮我一个忙。我怎么能只得到“A”、“B”、“C”而没有任何子值？
