Question

我正在为球队显示球场上的数据。我有正确的数据，但显示为[object，Object]。我如何在字段键中JSON.stringify？

 public config = {
columns: [
  { field: 'name', label: 'Name' }, //I get the name just fine
  { field: 'age', label: 'age' }, // I get the age just fine
  { field: 'teams', label: 'Teams' }, // I get all the teams but 
                                      // [object, Object] is shown
],
}

模板

  <tr *ngFor="let item of items ">
  <td *ngFor="let column of config.columns">
    <span *ngIf="!column.click && !column.link">
      {{item[column.field] | json}}
    </span>
    <span *ngIf="column.link">
      <a [routerLink]="[item.id, column.link]">
        {{item[column.field] | json}}
      </a>
    </span>
  </td>

</tr>

我如何在此处访问角色值。我使用'teams'字段获取此数据，但我需要专门访问角色。

[ { "programId": "feef40bb-c4a3-4185-9e89-162349acd9aad", "userId": "bab.admin", "role": "regionalManager", "id": "59408f47fd44df38a89db6e5", "created": "2017-06-14T01:20:07.273Z", "modified": "2017-06-14T01:20:07.273Z" }, { "programId": "fe2fa0bb-c3a3-4185-9e89-16779acd9aad", "userId": "bab.admin", "role": "salesManager", "id": "59408f47fd44df38a89db6e6", "created": "2017-06-14T01:20:07.275Z", "modified": "2017-06-14T01:20:07.275Z" }, ]
