[英]Cannot find a differ supporting object '[object Object]' of type 'object'. NgFor only supports binding to Iterables such as Array. json data
JSON 數據
data:[
{
assets:[[tool_order_id: "38",order_status_id: "10"]],
order_info:[id: "1", order_type: "6",check: "1", current_Stage_id: "29"]
},
{
assets:[tool_order_id: "1",order_status_id: "10"],
order_info:[id: "2", order_type: "3",check: "1", current_Stage_id: "29"]
},
{
assets:[[tool_order_id: "8",order_status_id: "10"]],
order_info:[id: "3", order_type: "3",check: "1", current_Stage_id: "29"]
},
{
assets:[tool_order_id: "3",order_status_id: "10"],
order_info:[id: "4", order_type: "3",check: "1", current_Stage_id: "29"]
}
]
如果我重復這個,我會收到錯誤。 找不到支持 object 類型為“object”的“[object Object]”的差異。 NgFor 只支持綁定到 Iterables 比如 Arrays 下面是 html
<div *ngIf="orders['assets'].length != 0">
<ion-row *ngFor="let tool of orders['assets']">
<ion-col col-4>{{ tool.tool_order_id }}</ion-col>
<ion-col col-4>{{ tool.order_status_id }}</ion-col>
</ion-row>
<div *ngIf="orders['assets'].length != 0">
<ion-row *ngFor="let tool of orders['assets']['0']">
<ion-col col-4>{{ tool.tool_order_id }}</ion-col>
<ion-col col-4>{{ tool.order_status_id }}</ion-col>
</ion-row>
並在 data.ts 文件中按順序存儲數據this.orders = this.data; console.log(this.orders);
this.orders = this.data; console.log(this.orders);
能夠在控制台中顯示數據。
如果它以某種方式進入控制台,你可以在循環內循環
<div ngbDropdownMenu aria-labelledby="dropdownMenuButton2" *ngFor="let pChannel of channels">
<div *ngFor="let channel of pChannel">
<a class="dropdown-item" (click)="getVouchersByChannelId(channel.channelId)">
{{ channel.channelName }}
</a>
</div>
</div>
嘗試這樣的事情
<ion-row *ngFor="let t of data">
<ion-row *ngFor="let tool of t.orders['assets']">
數據格式不正確。 [ ] 表示一個數組。 在數組中,您不能直接擁有鍵值對[tool_order_id: "38",order_status_id: "10"]
。 它應該是一個 object {tool_order_id: "38",order_status_id: "10"}
。 首先確保您的數據格式正確。
請消除數據中的不一致,例如第 1 行中的資產是 arrays 的數組,而第 2 行中它是一個數組。
資產:[[tool_order_id: "38",order_status_id: "10"]],
資產:[tool_order_id:“1”,order_status_id:“10”],
