需要有关嵌套数据的Angular数据表的帮助.

我想对表中的数据进行排序.

我使用的数据表来自 - https://www.npmjs.com/package/angular2-datatable

数据表适用于单个数组类型的数据.(用于许多角度应用)

问题:我已经嵌套了json(实际上,我有复杂的json,这里很简单)

感谢您查看这个.

任何建议或帮助表示赞赏.

JSON

records = [
  [
    {
      "name": "Subject Name",
      "type": "text",
      "id": "subjectName",
      "value": "DavidJ",
      "firstName": "David",
      "lastName": "John"
    },
    {
      "name": "QC Name",
      "type": "hidden",
      "id": "qcName",
      "value": "JosephT",
      "firstName": "Joseph",
      "lastName": "Tom"
    }
  ],
  [
    {
      "name": "Subject Name",
      "type": "text",
      "id": "subjectName",
      "value": "TigerC",
      "firstName": "Tiger",
      "lastName": "Chan"
    },
    {
      "name": "QC Name",
      "type": "hidden",
      "id": "qcName",
      "value": "ThomasR",
      "firstName": "Thomas",
      "lastName": "Richard"
    }
  ]
]

HTML …

我需要帮助在html中生成换行符.

使用Javascript

var x = "jun";
var y = "2015";

var calculate= x + "<br>" + y;

Html返回如下

<div>jan <br> 2015</div>

预期结果:我需要在html中换行,但不应该呈现<br>标记.

更新:我想要的是"jan"在第一行和下一行"2015"

我在c3图表x值中使用这些值.

的jsfiddle

提前致谢.

有谁能够帮我.

我试图从数组中排序字符串

var someArray= ["3a445a_V1", "3", "2a33s454_V1", "1", "3_V2", "2s4a34s3_V2", "234343"];

const [record] = someArray.map(r => parseFloat(r.replace('_V','.'))).sort((a,b) => a < b);

console.log(record)
//it returns 3a445a.1

JFIDDLE

在浏览器console.log中它工作正常,而不是打字稿？

打字稿,它给出了以下错误 错误:

error TS2345: Argument of type '(a: number, b: number) => boolean' is not 
assignable to parameter of type '(a: number, b: number) => number'.
      Type 'boolean' is not assignable to type 'number'.

任何的想法？提前致谢
