要在Angular 6中使用键盘回车键关闭模态框,您可以按照以下步骤进行操作:
npm install --save @angular/material @angular/cdk
import { MatDialogRef } from '@angular/material/dialog';
import { HostListener } from '@angular/core';
constructor(public dialogRef: MatDialogRef) {}
@HostListener('document:keydown.enter', ['$event'])
onKeydownHandler(event: KeyboardEvent) {
this.dialogRef.close();
}
这将在用户按下回车键时触发onKeydownHandler方法,并关闭模态框。
完整示例代码:
import { Component, OnInit } from '@angular/core';
import { MatDialogRef } from '@angular/material/dialog';
import { HostListener } from '@angular/core';
@Component({
selector: 'your-modal-component',
templateUrl: './your-modal-component.component.html',
styleUrls: ['./your-modal-component.component.css']
})
export class YourModalComponent implements OnInit {
constructor(public dialogRef: MatDialogRef) {}
ngOnInit() {}
@HostListener('document:keydown.enter', ['$event'])
onKeydownHandler(event: KeyboardEvent) {
this.dialogRef.close();
}
}
请注意,这个示例中的"YourModalComponent"应替换为您的实际模态框组件名称。
