在Angular中动态设置样式 [英] Set style dynamically in Angular

问题描述

我有以下标记

<tr *ngFor='let activity of pagedWorkflowActivities' style="background-color:{{activity.status == 'Pending' ? 'red' : 'green'}}">
.
.
.
.
</tr>

如前所述，如果activity.status字段待处理，则将背景色设置为红色，否则将设置为绿色.但这是行不通的.检查后，我发现它呈现为

As it says, if activity.status field is pending then make background color red otherwise green. But it doesn't work. After inspecting I found it renders it like

<tr ng-reflect-style="unsafe">

推荐答案

[style.background-color]="activity.status == 'Pending' ? 'red' : 'green'"

或

[ngStyle]="{'backgroundColor': activity.status == 'Pending' ? 'red' : 'green' }"
