要实现“Angular - 使用组件包装器和组件作为参数的材料模态框”,你可以按照以下步骤进行操作:
modal-wrapper
的组件包装器组件。这个组件将负责显示和管理材料模态框的打开和关闭。import { Component, ComponentFactoryResolver, OnInit, ViewChild, ViewContainerRef } from '@angular/core';
import { MatDialog } from '@angular/material/dialog';
@Component({
selector: 'app-modal-wrapper',
template: `
`,
})
export class ModalWrapperComponent implements OnInit {
@ViewChild('modalContainerRef', { read: ViewContainerRef }) modalContainerRef: ViewContainerRef;
constructor(private dialog: MatDialog, private componentFactoryResolver: ComponentFactoryResolver) {}
ngOnInit(): void {}
openModal(component: any): void {
this.modalContainerRef.clear();
const componentFactory = this.componentFactoryResolver.resolveComponentFactory(component);
const componentRef = this.modalContainerRef.createComponent(componentFactory);
const dialogRef = this.dialog.open(componentRef.instance);
dialogRef.afterClosed().subscribe(() => {
componentRef.destroy();
});
}
}
my-dialog
组件,它将作为参数传递给modal-wrapper
组件。import { Component } from '@angular/core';
import { MatDialogRef } from '@angular/material/dialog';
@Component({
selector: 'app-my-dialog',
template: `
My Dialog
Hello, this is my custom dialog content.
`,
})
export class MyDialogComponent {
constructor(public dialogRef: MatDialogRef) {}
}
modal-wrapper
组件。
import { Component } from '@angular/core';
import { ModalWrapperComponent } from './modal-wrapper.component';
import { MyDialogComponent } from './my-dialog.component';
@Component({
selector: 'app-my-component',
template: `
`,
})
export class MyComponent {
constructor(private modalWrapper: ModalWrapperComponent) {}
openDialog(): void {
this.modalWrapper.openModal(MyDialogComponent);
}
}
以上代码示例演示了如何创建一个可复用的组件包装器modal-wrapper
,以及如何使用modal-wrapper
组件来打开一个具体的材料模态框my-dialog
。
