在角度4中 .ts我想同时使用下拉菜单中的accounts.Id和accounts.Name。有可能吗?
<select [(ngModel)]="selectedName" class="form-control" (change)="SearchLedgerTransaction($event.target.value)">
<option value=""></option>
<option *ngFor="let accounts of accountledger" [value]="accounts.Id && accounts.Name">
{{accounts.Name}}
</option>
</select>
<br />
{{selectedName}} Account Ledger View

如果帐户列表很长,并且只想获取其ID和名称,则可以尝试以下方法:
-180/pi()*sign(x*y)*atan((abs(y)-abs(x))/(abs(y)+abs(x)))
然后,您的 selectedName 模型值将变为,例如: {id:1,name:'Kristy'}
已经创建了一个Stackblitz Demo供您参考。

1。)您可以选择分别指定[ngModel]和(ngModelChange)。
<option *ngFor="let accounts of accountledger"
[ngValue]="{id: accounts.Id, name: accounts.Name}"> // Use ngValue for multi-select control. Setup the object value you want to assign to the 'selectedName' model
{{accounts.Name}}
</option>
在您的组件上-分解参数,因为当前事件值是从选择框[ngValue]中传递的{id:accounts.Id,name:account.Name}
<select [ngModel]="selectedName"
(ngModelChange)="onSelectName($event)" // Call onSelectName function if select is actively changed
class="form-control" >
<option value=""></option>
<option *ngFor="let accounts of accountledger"
[ngValue]="{ id: accounts.Id, name: accounts.Name }"> // Pass Id and Name
{{accounts.Name}}
</option>
</select>

您可以使用类似..
<select [(ngModel)]="selectedName" class="form-control" (change)="SearchLedgerTransaction($event.target.value)">
<option value=""></option>
<option *ngFor="let accounts of accountledger" [value]="accounts">
{{accounts.Name}}
</option>
</select>
<br />
{{selectedName.Id}}{{selectedName.Name}} Account Ledger View
