每次单击模块扩展面板时,都会对该API进行HTTP调用,以使所有公司可用于该特定模块。
<mat-accordion *ngIf="modules">
<mat-expansion-panel *ngFor="let module of modules">
<mat-expansion-panel-header (click)="availableCompanies(module.module_name)">
<mat-panel-title>
{{module.module_name}}
</mat-panel-title>
</mat-expansion-panel-header>
HTTP响应(可用的公司):
{
"message": "Retrieved companies available to module",
"data": [
{ "co_code": "123", "name": "Company A" },
{ "co_code": "456", "name": "Company B" },
{ "co_code": "789", "name": "Company C" }
]
}
在每个模块扩展面板的内部,我想显示可用的公司作为清单。但是我在访问对象的键值并为每个复选框进行迭代时遇到了麻烦。到目前为止,这是我尝试过的:
<mat-list dense>
<mat-list-item *ngFor="let vertical of companies | keys">
<mat-checkbox *ngFor="let company of companies[vertical]">
{{company.name}}
</mat-checkbox>
</mat-list-item>
</mat-list>
我认为也许我需要改变使用按键管道或ngFor的方式?任何帮助或想法都会很棒,谢谢:)
这是list.component.ts:
export class listComponent implements OnInit {
@Input() modules: Module[];
@Input() companies: Company[] = [];
constructor(
private rs: RecipientService, // has getAvailableCompanies http method
) { }
ngOnInit() {
}
availableCompanies(vertical: string) {
this.rs.getAvailableCompanies(this.recipient.email_address, vertical).subscribe(res => {
this.companies[vertical] = res;
console.log(res);
console.log(this.companies);
});
}
}
console.log(res):
(3) [
{ "co_code": "123", "name": "Company A" },
{ "co_code": "456", "name": "Company B" },
{ "co_code": "789", "name": "Company C" }
]
console.log(this.companies) 跟踪单击的模块/垂直。 如果扩展了两个模块(信用卡和存款),则this.companies将存储module_names(密钥)和每个公司的可用数组:
[credit_cards: Array(3), deposits: Array(4)]
答案 0 :(得分:0)
您正尝试使用keyvalue
,但语法错误
除非您有自定义管道声明,否则您需要使用 keyvalue
,而不仅仅是 keys
。
<mat-list dense>
<mat-list-item *ngFor="let vertical of companies | keyvalue">
<mat-checkbox *ngFor="let company of companies[vertical]">
{{company.name}}
</mat-checkbox>
</mat-list-item>
</mat-list>
