角材料创建对话框与现有功能位于同一组件中

sky*_*dev 6 angular-material angular

我试图添加一个在我的Web服务执行之前被调用的Angular Material对话框(仅标题和yes / no)。事实是,我不想在单独的组件中创建对话框HTML。我需要对话框HTML与现有代码位于同一文件中。当我单击callAPI按钮时,对话框需要打开。这是我现有的组件代码

<mat-tab-group>
    <mat-tab label="Tab 1">
       <button mat-flat-button color="warn" (click)="callAPI()">Open Dialog</button>
    </mat-tab>
    <mat-tab label="Tab 2">
    </mat-tab>
</mat-tab-group>

callAPI() {
    this.http.get<any>('https://example.com/api').subscribe(data => {
      this.data = data;
      this.loading = false;
    },
    err => {
        this.loading = false;
    });
}

更新:我假设TemplateRef的类型参数是组件引用是不正确的- 事实上,它实际上是“嵌入视图的数据绑定上下文”,如该TemplateRef#createEmbeddedView方法的文档中所示:

abstract createEmbeddedView(context: C): EmbeddedViewRef<C>

描述:

基于此模板实例化嵌入视图,并将其附加到视图容器。

参数:

context(type C:) 嵌入视图的数据绑定上下文,在用法中声明。


您可以将模板引用传递给MatDialog#open

<ng-template #callAPIDialog>
    <h2 matDialogTitle>Hello dialog!</h2>
    <mat-dialog-actions align="end">
        <button mat-button matDialogClose="no">No</button>
        <button mat-button matDialogClose="yes">Yes</button>
    </mat-dialog-actions>
</ng-template>

import { TemplateRef, ViewChild } from '@angular/core';
import { MatDialog } from '@angular/material';

@Component({ /* */ })
export class MyComponent {

    @ViewChild('callAPIDialog') callAPIDialog: TemplateRef<any>;

    constructor(private dialog: MatDialog) { }

    callAPI() {
        let dialogRef = this.dialog.open(this.callAPIDialog);
        dialogRef.afterClosed().subscribe(result => {
            // Note: If the user clicks outside the dialog or presses the escape key, there'll be no result
            if (result !== undefined) {
                if (result === 'yes') {
                    // TODO: Replace the following line with your code.
                    console.log('User clicked yes.');
                } else if (result === 'no') {
                    // TODO: Replace the following line with your code.
                    console.log('User clicked no.');
                }
            }
        })
