无法解析MatDialogRef angular 4的所有参数 [英] Can't resolve all parameters for MatDialogRef angular 4

问题描述

我正在使用Angular 4，正在尝试设置材料包，在这里我尝试尝试对话框，但由于我不确定材料包而无法正常工作.

I'm working on Angular 4 and I'm trying to setup material package, and here I'm trying to try dialog, but it doesn't work maybe because of material package I'm not sure.

这是我的(dialog.components.ts):

This is my (dialog.components.ts):

import {Component, OnInit} from '@angular/core';
import {MatDialogRef} from '@angular/material'

@Component({
    selector: 'app-dialog',
    templateUrl: './dialog.component.html',
    styleUrls: ['./dialog.component.css']
})
export class DialogComponent implements OnInit {

    public receivedNode: any;

    constructor(public dialogRef: MatDialogRef<DialogComponent>) {
    }

    ngOnInit() {
    }

}

在我的模块中:

import {MatButtonModule,MatMenuModule,MatToolbarModule,MatIconModule,MatCardModule, MatDialogRef} from '@angular/material';


 @NgModule({
        imports: [
            CommonModule,
            MatButtonModule,
            MatMenuModule,
            MatToolbarModule,
            MatIconModule,
            MatCardModule,
            RouterModule.forRoot(
                appRoutes,
                {enableTracing: true}
            ),
        ],
        declarations: [],
        exports: [
            MatButtonModule,
            MatMenuModule,
            MatToolbarModule,
            MatIconModule,
            MatCardModule
        ],
        entryComponents: [DialogComponent],
        providers: [MatDialogRef]
    })
    export class DialogModule {
    }

我收到此错误:

有什么想法吗?

编辑

我的通话功能:

openPopup(){
        const config = new MatDialogConfig();
        const dialogRef: MatDialogRef<DialogComponent> = this.dialog.open(DialogComponent, config);

        dialogRef.componentInstance.receivedNode = "test";
        console.log("test");
    }

推荐答案

希望这可以帮助我完成此任务:

Hope this helps this is what I have done:

在组件上:

import { MatDialog } from '@angular/material';
import { DialogComponent } from './dialogs'; // component name of dialog can add multiple in here.

@Component({
    selector: 'yourComponent',
    templateUrl: './yourComponent.html'
})
export class YourComponent {

  private dialogRef: any;
  constructor(public dialog: MatDialog) {

  openPopup(){
    this.dialogRef = this.dialog.open(DialogComponent , {
                                    width: '250px',
                                    height: '25%',
                                    data: { errorcode: errorCode, errormessage: errorMessage }
                                });
                                this.dialogRef.updatePosition({ top: '3%', left: '20%' });
  }

在模块中:

import { DialogComponent } from './dialogs'; // component name of dialog
import { NgModule, CUSTOM_ELEMENTS_SCHEMA, NO_ERRORS_SCHEMA } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { MatDialogModule } from '@angular/material';

@NgModule({
    declarations: [
        DialogComponent 
    ],
    imports: [
        BrowserModule,
        MatDialogModule
    ],
    entryComponents: [
        DialogComponent 
    ],
    schemas: [CUSTOM_ELEMENTS_SCHEMA, NO_ERRORS_SCHEMA]
})

最后，出现对话框:

import {Component, OnInit} from '@angular/core';
import { MatDialogRef, MAT_DIALOG_DATA } from '@angular/material';

@Component({
    selector: 'app-dialog',
    templateUrl: './dialog.component.html',
    styleUrls: ['./dialog.component.css']
})
export class DialogComponent implements OnInit {

    constructor(public dialogRef: MatDialogRef<DialogComponent>, 
                @Inject(MAT_DIALOG_DATA) private data: any) { } // this.data.errormessage contain error message. Not sure if need OnInit.

    ngOnInit() {
    } // I have not used this. Instead, I have put the data in HTML and click on buttons from there to interact with the component.

}
