在角度上，如何用If .. then .. else条件实现* ngIf?标签? [英] In angular how to implement *ngIf with If .. then.. else condition inside a <td> tag?

问题描述

我尝试使用ngIf在表块中显示if else条件，但是我无法显示它.

I have tried to show the if else condition inside block of table using ngIf but i am not able to display it.

  <tr *ngFor="let client of clients">
<!--here i need to implement it-->
   <td *ngIf="!client.auditorGroup"; then 
   [ngStyle]="titleStyles else [ngStyle]="oldStyles1">{{client.selectionId}}</td>
   <td>{{client.selectionDate}}</td>
   <td>{{client.selectedBy}}</td>
   <td>{{client.panEximNumber}}</td>
   <td>{{client.name}}</td>
   <td>{{client.address}}</td>
   <td>{{client.phoneNumber}}</td>
   <td>{{client.selectionType}}</td>
   <td *ngIf="!client.auditorGroup" [ngStyle]="titleStyles">Edit
   Delete</td>
</tr>

推荐答案

否则，仅在ng-templates上使用，如果您需要条件样式，则可以使用ngClass或仅使用[class.someClass] ="condition"添加单个类或操纵样式使用[style.'some property']，因为您使用的是ngStyle，请尝试以下操作 在component.ts中，您可以具有一个根据条件(例如!client.auditorGroup

else and then can only used on ng-templates if you want conditional styles you could use ngClass or just add a single class using [class.someClass] ="condition" or manipulate the style using [style.'some property'] since you're using ngStyle try this in your component.ts you can have a function that returns your style depending on conditions such as your !client.auditorGroup

getStyle(value) { 
if(!value)
  return this.titleStyles;
}else {
  return this.oldStyles1;
}

，然后在您的component.html

and then in your component.html

<tr *ngFor="let client of clients">
<!--here i need to implement it-->
   <td 
   [ngStyle]="getStyle(client.auditorGroup)">{{client.selectionId}}</td>
   <td>{{client.selectionDate}}</td>
   <td>{{client.selectedBy}}</td>
   <td>{{client.panEximNumber}}</td>
   <td>{{client.name}}</td>
   <td>{{client.address}}</td>
   <td>{{client.phoneNumber}}</td>
   <td>{{client.selectionType}}</td>
   <td [ngStyle]="getStyle(client.auditorGroup)">Edit
   Delete</td>
</tr>
