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>

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
