如何将一个数组推入另一个数组内部的对象中？

标签： javascript multidimensional-array chart.js

在for循环中，我试图将变量数组推入对象内，而对象又位于数组内。 我正在尝试将数据推送到此处： enter image description here

展开的视图： enter image description here

数据最终位置： enter image description here

这是我的代码：

let that.dynamicDataCollection3 = [];
let allDeptNames=["Dept 1","Dept 2","Dept 3","Dept 4","Dept 17"];
let insPerDay =

正在记录以下内容（将数据推送到对象之外）：

that.dynamicDataCollection 对象/数组的预期输出应该是这样的：

[

   [{"label":"Dept 2","backgroundColor":"rgba(255, 80, 248, 0.06)","data":[0,0,43,0,66,13,12, 0,0,0],"borderColor":"rgba(255, 80, 248, 0.9)","borderWidth":2}],
   [{"label":"Dept 3","backgroundColor":"rgba(159, 255, 252, 0.06)","data":[0,0,49,0,22,12,8, 0,0,0],"borderColor":"rgba(159, 255, 252, 0.9)","borderWidth":2}],

关于如何解决这个问题的任何想法？

答案 0 :(得分：1)

尝试以下行：

that.dynamicDataCollection3[i].push({data: datasets});

答案 1 :(得分：1)

更改此：

  • 我在您的user: User = { userName: '', password: '', confirmPassword: '' }; submit() { console.log(this.user); } 模板中添加了一个空数组data 

    datasets

  • 将 let datasets = [ { label: allDeptNames[i], backgroundColor: lineColours[i], backgroundColor: lineBackColours[i], borderColor: lineColours[i], borderWidth: 2, data: [] // <- Add this } ] 更改为datasets.push(data ); 

datasets[0].data = data.map(i => i[0]);
