我有一个席位选择,其中包括两个选项：个人客户和组织客户.如果从下拉列表中选择Ind Cust,则应该看到三个选项名,姓氏和客户ID.但是,如果选择“组织客户”,则应该可以看到组织名称和组织ID.
我已经准备好所有HTML代码,但是无法基于选择显示选项.
<mat-form-field>
<mat-label>Select an option</mat-label>
<mat-select [(value)]="selected">
<mat-option value="indCust">IndividualCustomer</mat-option>
<mat-option value="orgCust">Organizational Customer</mat-option>
</mat-select>
</mat-form-field>
<div class="row" *ngIf="indCust; orgCust">
// Code for Input Box of Individual Customer
</div>
<ng-template #orgCust >
//Code for dropdown of Organization Customer
</ng-template>
打字稿代码
selected = '';
indCust: Boolean ;
if(this.selected == 'indCust'){
this.indCust = true;
} else {
this.indCust = false;
}
有人可以向我解释我做错了什么,并帮助我找出正确的方法.
最佳答案
我会这样：
<mat-form-field>
<mat-label>Select an option</mat-label>
<mat-select>
<mat-option *ngFor="let obj of list" (click)="get(obj)" [value]="obj"> {{obj.viewValue}}</mat-option>
</mat-select>
</mat-form-field>
<span *ngIf="isSelected">
<div class="row" *ngIf="indCust">
Code for Input Box of Individual Customer
<mat-form-field class="example-full-width">
<input matInput placeholder="Individual Customer" >
</mat-form-field>
</div>
<div class="row" *ngIf="!indCust">
Code for Combo Box of Organizational Customer
<mat-form-field>
<mat-label>Favorite food</mat-label>
<mat-select>
<mat-option *ngFor="let food of foods" [value]="food.value">
{{food.viewValue}}
</mat-option>
</mat-select>
</mat-form-field>
</div>
</span>
TS代码：
import { Component } from '@angular/core';
@Component({
selector: 'select-overview-example',templateUrl: 'select-overview-example.html',styleUrls: ['select-overview-example.css'],})
export class SelectOverviewExample {
list: any[] = [
{ value: 'indCust',viewValue: 'IndividualCustomer' },{ value: 'orgCust',viewValue: 'Organizational Customer' }
];
foods: any[] = [
{ value: 'steak-0',viewValue: 'Steak' },{ value: 'pizza-1',viewValue: 'Pizza' },{ value: 'tacos-2',viewValue: 'Tacos' }
];
isSelected: boolean = false;
indCust: Boolean = undefined;
get(data) {
this.isSelected = true;
if (data.value == 'indCust') {
this.indCust = true;
console.log(data)
} else {
this.indCust = false;
}
}
}
