html - 不同状态 Angular 6 的图标颜色

Question

我对 Angular 看法是这样的:

这是我的 dashboard.component.ts

export class DashboardComponent implements OnInit {
  tablePresetColumns;
  tablePresetData;
 ngOnInit() {
  this.tablePresetColumns = [{id: 1,content: 'Username'},{id: 2,content: 'Status'}];
  this.tablePresetData = [[{id: 1,content: 'john.doe@random.com'},{id: 2,content: 'Busy'}],[{id: 1,content: 'test2@random.com'},{id: 2,content: 'overload'}]];
 }
} 

这就是我在 dashboard.component 上调用表的方式:

<div eds-tile class="xl-4" style="height: 700px">
<eds-tile-title>User on Shift</eds-tile-title>  
<eds-table [columns]="tablePresetColumns" [data]="tablePresetData" [modes]="['compact', 'dashed']"></eds-table>
</div>

我的编辑表:

selector: 'eds-table',
template: "<table class=\"table\" [ngClass]=\"modes\">\n  <thead *ngIf=\"columns\">\n    <tr>\n      <th *ngFor=\"let col of columns\">\n        {{col.content}}\n      </th>\n    </tr>\n  </thead>\n  <tbody>\n    <tr *ngFor=\"let row of data\">\n      <td *ngFor=\"let cell of row\">\n        {{cell.content}}\n      </td>\n    </tr>\n  </tbody>\n</table>\n",

我的问题是，我应该怎么做才能使我的 View 至少变成这样，我的意思是有条件时状态为 Busy，

Icon Color are green, or Idle are Yellow, and Overload are Red (in the right of the text):

Answer 1

您可以在 <td> 使用以下内容

<td *ngFor="let cell of row" 
  [ngStyle]="{'color': (cell.content === 'Busy') ? 'green' : (cell.content === 'overload') ? 'red' : (cell.content === 'idle') ? 'yellow' : ''}">{{cell.content}}
</td>

或

通过下面的方式，

<td [ngClass]="{
                'busy' : cell.content == 'Busy',
                'idle' : cell.content == 'Idle'
                'overload' : cell.content == 'Overload'
             }" *ngFor="let cell of row"> {{cell.content}} </td>

在你的CSS中

.busy {
    color: green;
}

.idle {
    color: yellow;
}

.overload {
    color: red;
}

更新的答案

   <td *ngFor="let cell of row"> {{cell.content}} 
      <span class ="dot" [ngClass]="{
        'dot-red' : cell.content == 'Busy',
        'dot-green' : cell.content == 'Idle',
        'dot-yellow' : cell.content == 'overload'}"></span></td>

.dot {
  height: 20px;
  width: 20px;
  border-radius: 50%;
  display: inline-block;
}
.dot-red {
  background-color: red;
}
.dot-green {
  background-color: green;
}
.dot-yellow {
  background-color: yellow;
}
