Muh*_*eef 7 dialog typescript angular6 ngx-admin nebular
我正在尝试使用Nebular
组件在 Agnular6 上创建一个 Web 对话框。有两种方法可以做到这一点,第一种是传递<ng-template>
引用,例如:
openAddDialog = (dialogTemplate: TemplateRef<any>) => {
this.dialogServiceRef = this.dialogService.open(dialogTemplate);
}

它运行良好。但我需要的是将组件作为参数传递,例如:
dialogService.open(MyComponent);

我的应用程序中有这个结构:
|_ pages
| |_ pages.module.ts
| |_ patient
| |_ patient.module.ts
| |_ patient.component.ts
| |_ patient.component.html
|
|_ shared
|_ shared.module.ts
|_ components
| |_ search-bar.component.ts
| |_ search-bar.component.html
|
|_ modal-form
|_ modal-form.component.ts
|_ modal-from.component.html

我已经添加了ModalFormComponent
到declarations
,exports
和entryComponents
共享的模块中。此外,我将它导入到 SearchBar 组件中,并在单击 searchBar 中的按钮时运行此函数:
|_ pages
| |_ pages.module.ts
| |_ patient
| |_ patient.module.ts
| |_ patient.component.ts
| |_ patient.component.html
|
|_ shared
|_ shared.module.ts
|_ components
| |_ search-bar.component.ts
| |_ search-bar.component.html
|
|_ modal-form
|_ modal-form.component.ts
|_ modal-from.component.html

关于问题是什么以及我该如何解决的任何想法?
使用上下文参数传递所需的所有参数。
例如,假设有这个 SimpleInputDialogComponent:
import { Component, Input } from '@angular/core';
import { NbDialogRef } from '@nebular/theme';
@Component({
selector: 'ngx-simple-input-dialog',
templateUrl: 'simple-input-dialog.component.html',
styleUrls: ['simple-input-dialog.component.scss'],
})
export class SimpleInputDialogComponent {
title: String;
myObject: MyObject;
constructor(protected ref: NbDialogRef<SimpleInputDialogComponent>) {
}
cancel() {
this.ref.close();
}
submit(value: String) {
this.ref.close(value);
}
}

要传递标题和 myObject,请使用上下文参数:
const sampleObject = new MyObject();
this.dialogService.open(SimpleInputDialogComponent, {
context: {
title: 'Enter template name',
myObject: sampleObject,
},
})

尝试将组件放入模块中的entryComponents字段中(无论是主模块还是子模块,具体取决于您的情况)。
import {NgModule} from '@angular/core';
import {
//...
NbDialogModule
//...
} from '@nebular/theme';
@NgModule({
declarations: [
//...,
ModalFormComponent,
//...
],
entryComponents: [
//...
ModalFormComponent,
//...
],
imports: [
//...
// NbDialogModule.forChild() or NbDialogModule.forRoot()
//...
],
providers: [
//...
],
})
export class ExampleModule{
}
