以下演示的是在AngularJS的{{}}表达式中使用三目运算符,其实,在Javascript中,三目运算符的格式也与其一模一样,包括简写。
<div ng-if="scope=='all'" class="outline-border">
结果:巡检路线数量:
<strong>{{statistics.routesCount==undefined?0:statistics.routesCount}}</strong>
,覆盖设备设施总数:
<strong>{{statistics.routeEqTotal==undefined?0:statistics.routeEqTotal}}</strong>
,巡检整体覆盖率:<strong>{{statistics.eqCoverRate==undefined?0:statistics.eqCoverRate}}%</strong>
,特种设备数量:
<strong>{{statistics.routeSpecialEqTotal==undefined?"无":statistics.routeSpecialEqTotal}}</strong>
,特种设备巡检覆盖率:
<strong>{{statistics.eqSpecialCoverRate==undefined?0:statistics.eqSpecialCoverRate}}%</strong>.
</div>
如果是字符串,需要使用引号。

结果:巡检路线数量:
<strong>{{statistics.routesCount?statistics.routesCount:"字符串需使用引号"}}</strong>
,覆盖设备设施总数:
