angular - Angular2 How can I use ngIf correctly to show some text only when there's no data from server? -
i getting data server , using ngfor show them (it's search feature) when there's no result, want show text saying 'there's no result"
how can this?
i tried far isn't working.
<div *ngif="teainfo != '{}'"> <div class="starter-template text-xs-center"> <h5 style = "text-align:center">no result</h5> </div> </div>
use ngswitch check data exist , show default message if no data available below:
you can below result of if statement advisable use switch instead of if statement better performance perspective.
<div [ngswitch]="true"> <div *ngswitchcase="teainfo != null && teainfo.length>0"> //perform operation on data </div> <div *ngswitchdefault> there's no result </div> </div>
