我想创建一个解决方案来根据输入更改来更新可观察的数组对象
我正在使用ngFor从带有数组的表中创建一个表,其中angular具有一个带有出价值的文本字段。
我想要的是每当用户更新文本字段时,包含该出价值的对象应自动更新
这是我的代码
模板文件:
<table class="table table-striped applist-table table-bordered">
<thead>
<tr>
<th width="10%" class="text-center">App Id</th>
<th width="40%">App/Site Name</th>
<th width="30%">Exchange Name</th>
<th width="20%">Actions</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let a of apps | async">
<td width="15%" class="text-center">{{ a.sid }}</td>
<td width="40%">{{ a.appName }}</td>
<td width="30%">{{ a.exchange }}</td>
<td width="15%">
<div class="input-group">
<input type="text" class="form-control" value="{{a.dynamic_bid}}" #bid />
<div class="input-group-append">
</div>
</div>
</td>
</tr>
</tbody>
</table>
component.ts
apps: Apps[] = [];
openBidUpdateOptions(content) {
this.loading = true;
this._campaignOperations.loadCampaignApplistData(this.id).subscribe(
data => {
if (data.status == 1200) {
this.loading = false;
this.apps = data.data;
this.modalReference = this.modalService.open(content, {
size: 'lg'
});
this.modalReference.result.then((result) => {
}, (reason) => {
});
this.loading = false;
} else {
let str: any = '';
let errorList = data.errors;
for (let i in errorList) {
str += errorList[i] + "<br>";
}
this.toastr.error(str, 'Error');
this.loading = false;
return false;
}
},
error => {
swal({
position: 'center',
type: 'error',
title: 'Unable to create campaign due to unknown error',
showConfirmButton: false,
timer: 1500
});
this.loading = false;
return false;
});
}
export interface Apps {
id ? : string;
sid ? : string;
appName ? : string;
exchange ? : string;
dynamic_bid ? : string;
}
答案 0 :(得分:2)
我不确定我是否理解您的问题。但我认为您可以使用ngModel:
<input type="text" class="form-control" [(ngModel)]="a.dynamic_bid" #bid />
