Syntax * ngFor = '...' eckig 2

Question

Hilfe mit Syntax bitte. Ich würde zwei Objekte analysiert (Daten in Tabelle Anzeige) ->

<tbody> 
     <tr *ngFor="let service_rec of list.servicelist" *ngFor= "let service_rec of list.storagelist"> 
      <td> {{ service_rec.name }} </td> 
      <td> {{ service_rec.status }}</td> 
      <td>{{ service_rec.total | byteFormat }}</td> 
      <td>{{ service_rec.used | byteFormat }}</td> 
      <td>{{ service_rec.free | byteFormat }}</td> 
     </tr> 
    </tbody> 

Wie kombinieren (mit Syntax) list.servicelict & list.storagelist,

ich habe Fehler "NaN undefined"

UPD:

<div class="panel-header text-center"> 
    <h1> Тест блок </h1> 
</div> 

<div class="row" *ngFor="let list of lists"> 
<div class="col-md-6"> 
    <table class="table table-bordered"> 
     <caption>{{ list.nodename }}</caption> 
     <thead> 
      <tr> 
       <th rowspan="2" style="text-align: center;">Название сервиса</th> 
       <th rowspan="2" style="text-align: center;">Статус</th> 
       <th colspan="3" style="text-align: center;">Файловая система</th> 
      </tr> 
      <tr> 
       <th>Всего</th> 
       <th>Использовано</th> 
       <th>Доступно</th> 
      </tr> 
     </thead> 
     <tbody> 
      <template ngFor let-service_rec [ngForOf]="list.servicelist"> 
      <tr *ngFor= "let service_rec of list.storagelist"> 
       <td> {{ service_rec.name }} </td> 
       <td style="width: 15%"> 
        <span [style.background-color]="service_rec.status == 'Online' ? 'green' : 'red'" class="label label-default"> 
         {{ service_rec.status }} 
        </span> 
       </td> 
       <td>{{ service_rec.total | byteFormat }}</td> 
       <td>{{ service_rec.used | byteFormat }}</td> 
       <td>{{ service_rec.free | byteFormat }}</td> 
      </tr> 
      </template> 
     </tbody> 
    </table> 
</div> 
</div> 

Wenn ich hinzufügen

Daten in der Zeile "Название сервиса" & "Статус" sind

gegangen

[ 
    {"nodename":"192.124.105.55", 
    "servicelist":[ 
     {

     } 
    ], 
    "storagelist":

    { 
     "mountpoint":"/",

    } 
    ]

Sie können nicht zwei strukturellen Richtlinien auf dem gleichen Element haben (2 x *ngFor) Wenn Sie mehr als eins benötigen, müssen Sie das Formular mit einem eindeutigen <template> Tag verwenden:

<tbody> 
    <template ngFor let-service_rec [ngForOf]="list.servicelist"> 
    <tr *ngFor= "let service_rec of list.storagelist"> 
     <td> {{ service_rec.name }} </td> 
     <td> {{ service_rec.status }}</td> 
     <td>{{ service_rec.total | byteFormat }}</td> 
     <td>{{ service_rec.used | byteFormat }}</td> 
     <td>{{ service_rec.free | byteFormat }}</td> 
    </tr> 
    </template> 
</tbody>
