香港專業教育學院得到了與3 foreach循環的離子型格海誓山盟 裏面最外環是這樣的:離子2新行,如果索引%3 == 0
<ion-content padding>
<ion-grid>
<ion-row>
<ion-col>
<ion-row>
<ion-col *ngFor="let field1 of gs.fields; let x = index; trackBy: trackByFn">
<!-- More Foreach Loops inside each other-->
</ion-col>
</ion-row>
</ion-col>
</ion-row>
</ion-grid>
</ion-content>
但我想要每次都得到一個新的行x%3 == 0 [如果我保持循環的第一個外部我需要x%3 == 0 & & x!= 0] 我希望將所有內容保留在循環中相同而不是複製代碼

我首先想到的是做這樣的事情:
<ion-content padding>
<ion-grid>
<ion-row>
<ion-col>
<ion-row>
<ion-col *ngFor="let field1 of gs.fields; let x = index; trackBy: trackByFn">
<ion-row *ngIf="x%3==0 && x!=0">
<!-- More Foreach Loops inside each other-->
</ion-row *ngIf="x%3==0 && x!=0">
</ion-col>
</ion-row>
</ion-col>
</ion-row>
</ion-grid>
</ion-content>
X在0-8的範圍內運行,所以</ion-row *ngIf="x%3==0 && x!=0">
爲關閉標籤應該沒問題,因爲我關閉了outter foreach循環外的離子行。但是這不是加載。
它是如何:
如何我希望它是:
<ion-content padding>
<ion-grid>
<ion-row>
<ion-col *ngFor="let field1 of gs.fields; let x = index; trackBy: trackByFn">
<div *ngIf="gs.won_fields[x] == false" [ngClass]="{'bordern':x%2==0,'bordernplus1':x%2!=0}">
<ion-col *ngFor="let field2 of field1; let y = index; trackBy: trackByFn">
<ion-row>
<ion-col class="ctr fc tile" *ngFor="let tile of field2; let z = index; trackBy: trackByFn" (click)="playerClick(x,y,z)">
<span class="ctr" [ngClass]="{'player1': tile==1, 'player2' : tile==2}">{{(tile==0)? ' ': ((tile==1)? 'x' : 'o')}}</span>
</ion-col>
</ion-row>
</ion-col>
</div>
<!-- Wenn Feld gewonnen x oder o eintragen -->
<span class="ctr tile" *ngIf="gs.won_fields[x] != false" [ngClass]="{'bordern':x%2==0,'bordernplus1':x%2!=0}" [ngClass]="{'player1': gs.won_fields[x]===1, 'player2' : gs.won_fields[x]===2}">{{(gs.won_fields[x]==1)? 'x' : 'o'}}</span>
</ion-col>
</ion-row>
</ion-grid>
</ion-content>
你能展示'gs.fields'的結構嗎? –
