我有几个输入字段(数字),是最后一个(禁用)它们是求和或减法的结果。所有这些都有货币掩码,包括总字段。问题是填充它们时,总字段不会采用小数,只有在我启用它时,键入一个数字。然后出现小数。有人可以帮忙解决问题吗?
HTML:
<div class="row">
<div class="col-md-4">
<input [(ngModel)]="mainBudget.budget.own_resources" class="form-control" placeholder="{{dataResources.placeholder.euro}}"
type="text" currencyMask required>
</div>
</div>
<div class="row">
<div class="col-md-4">
<input [(ngModel)]="mainBudget.budget.revenues_generated_by_project" class="form-control" type="text" currencyMask placeholder="{{dataResources.placeholder.euro}}"
required>
</div>
</div>
<div class="row">
<div class="col-md-4">
<input class="form-control disabled" disabled type="text" currencyMask [value]="totalBudget()" placeholder="{{dataResources.placeholder.euro}}"
required>
</div>
</div>
总和方法:
totalBudget(): number {
return this.mainBudget.budget.own_resources +
this.mainBudget.budget.revenues_generated_by_project;
}

将此函数totalBudget()添加到
中ngOnInit(){}或在里面添加:
setInterval(()=&gt; {this.totalBudget();},500);

我使用了ngModel,就像这样:
TS
total:number;
totalBudget(): boolean{
this.total = this.mainBudget.budget.own_resources +
this.mainBudget.budget.revenues_generated_by_project;
return true ;
}
HTML
<div class="row">
<div class="col-md-4" *ngIf="totalBudget()">
<input class="form-control" type="text" disabled currencyMask [(ngModel)]="total"
required>
</div>
</div>
