在父组件(app.component.html)中:--。
<stl-app [filename]="'abc.STL'" [colorname]="'red'" [perspective]="35"></stl-app>
在父组件.ts (app.component.ts):---。
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {
title = 'stl-app';
@ViewChild(ImlStlAppComponent) child:ImlStlAppComponent;
constructor(){}
ngOnInit():void{}
ngAfterViewInit(){
this.child.mySubmit();
}
在子组件(stl-app.component.html)中:-。
<mat-form-field>
<mat-label>Name of the file</mat-label>
<mat-hint> File path of only stl file</mat-hint>
<input matInput [(ngModel)]="filename" name="filename" required>
</mat-form-field>
<mat-form-field>
<mat-label>Name of the color</mat-label>
<mat-hint> Color in string</mat-hint>
<input matInput [(ngModel)]="colorname" name="colorname" required>
</mat-form-field>
<mat-form-field>
<mat-label>Camera Perspective</mat-label>
<mat-hint> values in Integer</mat-hint>
<input matInput [(ngModel)]="perspective" name="perspective" required>
</mat-form-field>
<button mat-raised-button (click)="mySubmit()" color="primary">Submit</button>
在子组件.ts (stl-app.component.ts):- 中。
export class ImlStlAppComponent implements OnInit {
@Input()
filename:string;
@Input()
colorname:any;
@Input()
perspective:number;
mySubmit(){
//Something Todo----
}
}
当我点击 "提交 "按钮时,mySubmit()方法并没有用父组件.html中已经给出的值来触发,因此什么也没有呈现。如何避免这个问题?
父组件的TS代码
@Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.scss'] }) export class AppComponent implements OnInit { title = 'stl-app';
pFileName = 'somefilename';
pColorName = 'somecolorname';
pPerspective = 'someperspective';
@ViewChild(ImlStlAppComponent) child:ImlStlAppComponent;
constructor(){} ngOnInit():void{}
ngAfterViewInit(){ this.child.mySubmit(); }
母体的HTML
<stl-app [filename]='pFileName' [colorname]='pColorName' [perspective]='pPerspective'></stl-app>
请让我知道,如果它对你有效或不有效。
