Javascript 如何在angularjs中从json获取特定的唯一值

我的json是这样的

{
"Project_details": [
    {
        "Project_ID": "1245353445",
        "Name": "Test1",
        "Releases": [
            {
                "sid_ratio": "5.0",
                "release_version": "13.2",
                "pre_delivery": {
                    "total": "13",
                    "blocker": "2",
                    "critical": "2",
                    "major": "4",
                    "normal": "6",
                    "minor": "1"
                },
                "post_delivery": {
                    "total": "3",
                    "blocker": "2",
                    "critical": "0",
                    "major": "1",
                    "normal": "1",
                    "minor": "1"
                }
            },
            {
                "sid_ratio": "15.0",
                "release_version": "14.1",
                "pre_delivery": {
                    "total": "13",
                    "blocker": "3",
                    "critical": "2",
                    "major": "4",
                    "normal": "6",
                    "minor": "1"
                },
                "post_delivery": {
                    "total": "3",
                    "blocker": "3",
                    "critical": "0",
                    "major": "1",
                    "normal": "1",
                    "minor": "1"
                }
            },
            {
                "sid_ratio": "15.0",
                "release_version": "14.2",
                "pre_delivery": {
                    "total": "13",
                    "blocker": "0",
                    "critical": "2",
                    "major": "4",
                    "normal": "6",
                    "minor": "1"
                },
                "post_delivery": {
                    "total": "3",
                    "blocker": "0",
                    "critical": "0",
                    "major": "1",
                    "normal": "1",
                    "minor": "1"
                }
            }
        ]
    }
]
}

我想在一个阵列中获得唯一的发布版本

我需要另一个数组中的键“Project ID”和“Name”

---

如何使用angularjs实现这一点？这些数据我想在控制器中获取，并将这些数组分配给$scope..

没有特定于角度的数据。最终代码（原始javascript）：

我知道那个问题被接受了。我喜欢纯javascript。但我无法阻止自己使用提供一个优雅的解决方案

正如我正确理解的，您需要两个不同的数组

在数组中提取发布\u版本

_.pluck(data['Project_details'][0]['Releases'], 'release_version');
// ["13.2", "14.1", "14.2"]

提取项目Id和名称

_.pick(data['Project_details'][0], ['Project_ID', 'Name'])
// Object {Project_ID: "1245353445", Name: "Test1"}

使用索引

0

是因为您的项目\u details数组中只有一行。

使用

angular.forEach从Json获取特定唯一值的简单方法

var notificationcontent = [{"type":"success","title":"title","body":"Your deadline to open an Term deposit and save thousands in taxes is june 20th!","timeout":"0","bodyOutputType":"trustedHtml","clickHandler":""},

{"type":"error","title":"title","body":"This month, Your spent Rs.500.05 on restaurants. This exceeds your budget of Rs.300 by Rs.200.","timeout":"0","bodyOutputType":"trustedHtml","clickHandler":""},

{"type":"warning","title":"title","body":"This month, Your spent Rs.500.05 on Gas and Fuel. This exceeds your budget of Rs.800 by Rs.200.","timeout":"0","bodyOutputType":"trustedHtml","clickHandler":""}];

angular.forEach ( notificationcontent, function(value, key) {alert(value.type);console.log(value.body);});

但这与角度无关。您需要的是在数组上循环并查找其中的内容。你试过什么吗？张贴您遇到问题的代码。谢谢您的回答。我刚试过这个，效果很好。
_.pick(data['Project_details'][0], ['Project_ID', 'Name'])
// Object {Project_ID: "1245353445", Name: "Test1"}

var notificationcontent = [{"type":"success","title":"title","body":"Your deadline to open an Term deposit and save thousands in taxes is june 20th!","timeout":"0","bodyOutputType":"trustedHtml","clickHandler":""},

{"type":"error","title":"title","body":"This month, Your spent Rs.500.05 on restaurants. This exceeds your budget of Rs.300 by Rs.200.","timeout":"0","bodyOutputType":"trustedHtml","clickHandler":""},

{"type":"warning","title":"title","body":"This month, Your spent Rs.500.05 on Gas and Fuel. This exceeds your budget of Rs.800 by Rs.200.","timeout":"0","bodyOutputType":"trustedHtml","clickHandler":""}];

angular.forEach ( notificationcontent, function(value, key) {alert(value.type);console.log(value.body);});
