如何在angularjs

Question

我正在将json对象转换为数组。我得到的数据如下。我尝试使用Google，但找不到答案。如何通过下面的数据解决此问题

[{"january":"0.00","february":"0.00","mac":"1271.00","april":"5.00","may":"0.00","june":"0.00","july":"0.00","august":"0.00","september":"0.00","october":"0.00","november":"0.00","december":"0.00"}]

进入此

$scope.data = [
        [0.00, 0.00, 1271.00, 5.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00]
      ];

在file.html

中

<div class="card">
    <div class="card-header">
         <i class="icon-graph icon-bg"></i>Bar Chart
    </div>
    <canvas id="bar" class="chart chart-bar" chart-data="graph" chart-labels="labels"></canvas>

</div>

在file.js中

$http.get(commonData.apiURL + 'dashboard/countDataGraph.php')
        .success(function (data) {
            $scope.graph = data;
            console.log(JSON.stringify(data));

        })
        .error(function (data, status, headers, config) {
            $scope.errorMessage = "Couldn't load the list of Orders, error # " + status;
            console.log("error");
    });

Answer 1

JavaScript中的对象属性是无序的，因此使用Object.values()的解决方案不能保证生成的数组正确排序。

您必须以正确的顺序获取各个值，并从中构造一个新的数组。预定义一系列的月份，并结合map()操作将达到目的：

const months = ['january', 'february', 'march', 'april', 'may', 'june', 'july', 'august', 'september', 'october', 'november', 'december'];
const data = [{"january":"0.00","february":"0.00","march":"1271.00","april":"5.00","may":"0.00","june":"0.00","july":"0.00","august":"0.00","september":"0.00","october":"0.00","november":"0.00","december":"0.00"}];

const result = data.map(v => months.map(m => v[m]));
       
console.log(result);

Answer 2

您可以使用函数Object.values

Object.values(o) // Returns an array of values.

let obj = [{"january":"0.00","february":"0.00","mac":"1271.00","april":"5.00","may":"0.00","june":"0.00","july":"0.00","august":"0.00","september":"0.00","october":"0.00","november":"0.00","december":"0.00"}];
let values = obj.map(Object.values);
console.log(values);

.as-console-wrapper { max-height: 100% !important; top: 0; }

Answer 3

您可以使用map()和Object.values

const arr = [{"january":"0.00","february":"0.00","mac":"1271.00","april":"5.00","may":"0.00","june":"0.00","july":"0.00","august":"0.00","september":"0.00","october":"0.00","november":"0.00","december":"0.00"}]

const res = arr.map(x => Object.values(x));

console.log(res);
