My issue rests on what I believe to be a misuse of the image carousel html code structure. Here is my Html:
<div id="carousel-trades" class="carousel slide carousel-fade" data-ride="carousel">
<div class="carousel-inner" role="listbox">
<div *ngFor="let ytd of yourTrades; let i = index" class="carousel-item {{ (i == 0) ? 'active' : ''}}">
<img style="width:310px;height:310px" [src]="splitImageString(ytd.tradeUrl)" (click)="pickImageForTrade(yourTradeImage)"
alt="First slide">
</div>
</div>
</div>
Also I there is the possibility that the array "yourTrades" is not being initialized due to being out of scope.
component.ts file:
yourTrades: Trade[];
ngOnInit(): void {
this.resetForm();
this.serviceTrade.getUserId()
.subscribe(data => {
this.myId = data;
let yourTrades = new Array();
for (let i = 0; i < this.trades.length; i++) {
if (this.myId.userId == this.trades[i].userId) {
yourTrades.push(this.trades[i]);
}
}
console.log(yourTrades);
})
}
When I call console.log I get the expected array of objects but when my carousel renders it returns empty. It must be the fact that there may be a wrong connection from when "yourTrades" is populated to when it is used by the html?
Change your caraousel html to:-
<div id="carousel-trades" class="carousel slide carousel-fade" data-ride="carousel">
<div class="carousel-inner" role="listbox">
<div *ngFor="let ytd of yourTrades; let i = index" class="carousel-item" [ngClass]="{'active': i===0}">
<img style="width:310px;height:310px" [src]="splitImageString(ytd.tradeUrl)" (click)="pickImageForTrade(yourTradeImage)"
alt="First slide">
</div>
</div>
</div>
You aren't assigning the yourTrades
variable inside the subscription to the member variable. Try the following
yourTrades: Trade[] = []; // <-- assign empty array
this.serviceTrade.getUserId()
.subscribe(data => {
this.myId = data;
for (let i = 0; i < this.trades.length; i++) {
if (this.myId.userId == this.trades[i].userId) {
this.yourTrades.push(this.trades[i]); // <-- directly push to the member variable
}
}
console.log(this.yourTrades);
});
}
