我正在尝试创建一个表单,其中包含两个使用 Angular Material 的开始/结束日期日期选择器。由于某种原因,当我在对话框窗口中的表单内添加日期选择器时,对话框的布局未正确呈现,正如从图像中可以看到的那样。这可能是什么原因造成的?
模板:
<div class="consumption-form">
<form [formGroup]="consumptionControl" id="consumptionForm">
<p class="consumption-field">
<mat-form-field hintLabel="Max 10 characters" appearance="fill">
<mat-label>BGpoint</mat-label>
<input matInput #BGpoint maxlength="10" placeholder="BG5521900640000000000000001668712" formControlName="BGpointControl">
<mat-error>
<span *ngIf="consumptionControl?.controls.BGpointControl?.errors?.pattern">Field should contain 10 numeric
characters!</span>
</mat-error>
<mat-hint align="end">{{BGpoint.value?.length || 0}}/10</mat-hint>
</mat-form-field>
</p>
<p class="consumption-field">
<mat-form-field appearance="fill">
<mat-label>Choose a start date</mat-label>
<input matInput [matDatepickerFilter]="myFilter" [matDatepicker]="picker">
<mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
<mat-datepicker #picker></mat-datepicker>
</mat-form-field>
</p>
<button mat-raised-button type="submit" (click)="submit(BGpoint) " mat-icon-button matTooltip="Click to search for results " [matTooltipPosition]="position.value " [matTooltipShowDelay]="500
" [matTooltipHideDelay]="500">
<mat-icon aria-label="Search button icon ">search</mat-icon>
</button>
</form>
</div>
组件ts:
import { Component, OnInit } from '@angular/core';
import { FormGroup, FormControl, Validators } from '@angular/forms';
import { TooltipPosition } from '@angular/material/tooltip';
@Component({
selector: 'app-consumption-details',
templateUrl: './consumption-details.component.html',
styleUrls: ['./consumption-details.component.css']
})
export class ConsumptionDetailsComponent implements OnInit {
myFilter = (d: Date | null): boolean => {
const day = (d || new Date()).getDay();
// Prevent Saturday and Sunday from being selected.
return day !== 0 && day !== 6;
}
consumptionControl: FormGroup;
private positionOptions: TooltipPosition[] = ['after', 'before', 'above', 'below', 'left', 'right'];
position = new FormControl(this.positionOptions[0]);
constructor() { }
ngOnInit(): void {
this.consumptionControl = new FormGroup({
BGpointControl: new FormControl('', [Validators.minLength(1), Validators.maxLength(20), Validators.pattern("*")]),
});
}
submit(BGPoint:string){
}
}
对话框窗口在屏幕左侧显示为从上到下的白色条带。
我知道我来晚了一点,但我刚刚遇到了和OP类似的问题。就我而言,mat-datepicker 工作得很好,直到我尝试将其放入 mat-dialog 窗口中的表单中。 尽管
MatNativeDateModule
和 MatDatepickerModule
已导入到我的模块中,但我仍然在控制台中得到 ERROR Error: MatDatepicker: No provider found for DateAdapter
。
对我有用的是在
MyModule
和 AppModule
和 中导入上述模块,同时将 MatDatepickerModule
注册为 MyModule
中的提供者。
对于独立组件,有时在对话框组件中导入
MatDatepickerModule
和 MatNativeDateModule
可能还不够(尽管您肯定需要这两个)。
由角度材质对话框服务实例化的组件无法访问应用程序全局注入器。这对我有帮助:
constructor(private dialog: MatDialog,
private injector: Injector) {}
openResponseModal() {
this.dialog.open(MyModalComponent, {
data: {
// ... injected data
},
injector: this.injector,
});
}
按照@nikoswsn链接的答案,在组件的模块中导入
MatNativeDateModule
对我有用。
import { MatDatepickerModule } from '@angular/material/datepicker';
import { MatNativeDateModule } from '@angular/material/core';
// ...
@NgModule({
imports: [
MatDatepickerModule,
MatNativeDateModule,
// ...
