这是从服务器生成的动态表单控件的示例。

https://stackblitz.com/edit/angular-t3mmg6

这个例子是在添加组件中的动态表单控件(这是你可以从服务器获取表单控件的地方)。如果你看到addcomponent method，你可以看到表单控件。在这个例子中，我没有使用角材料，但它工作(我使用@ work)。这是angular 6的目标，但在之前的所有版本中都有效。

需要为AngularVersion 5及以上版本添加JITComplierFactory。

谢谢

我决定把我学到的东西都压缩到一个文件里。 与RC5之前相比，这里有很多东西值得考虑。注意，这个源文件包括AppModule和AppComponent。

import {
  Component, Input, ReflectiveInjector, ViewContainerRef, Compiler, NgModule, ModuleWithComponentFactories,
  OnInit, ViewChild
} from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';

@Component({
  selector: 'app-dynamic',
  template: '<h4>Dynamic Components</h4><br>'
})
export class DynamicComponentRenderer implements OnInit {

  factory: ModuleWithComponentFactories<DynamicModule>;

  constructor(private vcRef: ViewContainerRef, private compiler: Compiler) { }

  ngOnInit() {
    if (!this.factory) {
      const dynamicComponents = {
        sayName1: {comp: SayNameComponent, inputs: {name: 'Andrew Wiles'}},
        sayAge1: {comp: SayAgeComponent, inputs: {age: 30}},
        sayName2: {comp: SayNameComponent, inputs: {name: 'Richard Taylor'}},
        sayAge2: {comp: SayAgeComponent, inputs: {age: 25}}};
      this.compiler.compileModuleAndAllComponentsAsync(DynamicModule)
        .then((moduleWithComponentFactories: ModuleWithComponentFactories<DynamicModule>) => {
          this.factory = moduleWithComponentFactories;
          Object.keys(dynamicComponents).forEach(k => {
            this.add(dynamicComponents[k]);
          })
        });
    }
  }

  addNewName(value: string) {
    this.add({comp: SayNameComponent, inputs: {name: value}})
  }

  addNewAge(value: number) {
    this.add({comp: SayAgeComponent, inputs: {age: value}})
  }

  add(comp: any) {
    const compFactory = this.factory.componentFactories.find(x => x.componentType === comp.comp);
    // If we don't want to hold a reference to the component type, we can also say: const compFactory = this.factory.componentFactories.find(x => x.selector === 'my-component-selector');
    const injector = ReflectiveInjector.fromResolvedProviders([], this.vcRef.parentInjector);
    const cmpRef = this.vcRef.createComponent(compFactory, this.vcRef.length, injector, []);
    Object.keys(comp.inputs).forEach(i => cmpRef.instance[i] = comp.inputs[i]);
  }
}

@Component({
  selector: 'app-age',
  template: '<div>My age is {{age}}!</div>'
})
class SayAgeComponent {
  @Input() public age: number;
};

@Component({
  selector: 'app-name',
  template: '<div>My name is {{name}}!</div>'
})
class SayNameComponent {
  @Input() public name: string;
};

@NgModule({
  imports: [BrowserModule],
  declarations: [SayAgeComponent, SayNameComponent]
})
class DynamicModule {}

@Component({
  selector: 'app-root',
  template: `
        <h3>{{message}}</h3>
        <app-dynamic #ad></app-dynamic>
        <br>
        <input #name type="text" placeholder="name">
        <button (click)="ad.addNewName(name.value)">Add Name</button>
        <br>
        <input #age type="number" placeholder="age">
        <button (click)="ad.addNewAge(age.value)">Add Age</button>
    `,
})
export class AppComponent {
  message = 'this is app component';
  @ViewChild(DynamicComponentRenderer) dcr;

}

@NgModule({
  imports: [BrowserModule],
  declarations: [AppComponent, DynamicComponentRenderer],
  bootstrap: [AppComponent]
})
export class AppModule {}`

EDIT (26/08/2017): The solution below works well with Angular2 and 4. I've updated it to contain a template variable and click handler and tested it with Angular 4.3. For Angular4, ngComponentOutlet as described in Ophir's answer is a much better solution. But right now it does not support inputs & outputs yet. If [this PR](https://github.com/angular/angular/pull/15362] is accepted, it would be possible through the component instance returned by the create event. ng-dynamic-component may be the best and simplest solution altogether, but I haven't tested that yet.

@Long Field的答案是正确的!下面是另一个(同步)例子:

import {Compiler, Component, NgModule, OnInit, ViewChild,
  ViewContainerRef} from '@angular/core'
import {BrowserModule} from '@angular/platform-browser'

@Component({
  selector: 'my-app',
  template: `<h1>Dynamic template:</h1>
             <div #container></div>`
})
export class App implements OnInit {
  @ViewChild('container', { read: ViewContainerRef }) container: ViewContainerRef;

  constructor(private compiler: Compiler) {}

  ngOnInit() {
    this.addComponent(
      `<h4 (click)="increaseCounter()">
        Click to increase: {{counter}}
      `enter code here` </h4>`,
      {
        counter: 1,
        increaseCounter: function () {
          this.counter++;
        }
      }
    );
  }

  private addComponent(template: string, properties?: any = {}) {
    @Component({template})
    class TemplateComponent {}

    @NgModule({declarations: [TemplateComponent]})
    class TemplateModule {}

    const mod = this.compiler.compileModuleAndAllComponentsSync(TemplateModule);
    const factory = mod.componentFactories.find((comp) =>
      comp.componentType === TemplateComponent
    );
    const component = this.container.createComponent(factory);
    Object.assign(component.instance, properties);
    // If properties are changed at a later stage, the change detection
    // may need to be triggered manually:
    // component.changeDetectorRef.detectChanges();
  }
}

@NgModule({
  imports: [ BrowserModule ],
  declarations: [ App ],
  bootstrap: [ App ]
})
export class AppModule {}

在Angular 2 Final版本中，通过使用ng-dynamic中的dynamicComponent指令解决了这个问题。

用法:

<div *dynamicComponent="template; context: {text: text};"></div>

其中template是您的动态模板，context可以设置为您希望模板绑定到的任何动态数据模型。

在角7。我使用了角元素。

安装@angular-elements NPM I @angular/elements 创建配件服务。

import { Injectable, Injector } from '@angular/core';
import { createCustomElement } from '@angular/elements';
import { IStringAnyMap } from 'src/app/core/models';
import { AppUserIconComponent } from 'src/app/shared';

const COMPONENTS = {
  'user-icon': AppUserIconComponent
};

@Injectable({
  providedIn: 'root'
})
export class DynamicComponentsService {
  constructor(private injector: Injector) {

  }

  public register(): void {
    Object.entries(COMPONENTS).forEach(([key, component]: [string, any]) => {
      const CustomElement = createCustomElement(component, { injector: this.injector });
      customElements.define(key, CustomElement);
    });
  }

  public create(tagName: string, data: IStringAnyMap = {}): HTMLElement {
    const customEl = document.createElement(tagName);

    Object.entries(data).forEach(([key, value]: [string, any]) => {
      customEl[key] = value;
    });

    return customEl;
  }
}

注意，你的自定义元素标签必须与angular组件选择器不同。 在AppUserIconComponent:

...
selector: app-user-icon
...

在这种情况下，自定义标签名称我使用“user-icon”。

然后你必须在AppComponent中调用register:

@Component({
  selector: 'app-root',
  template: '<router-outlet></router-outlet>'
})
export class AppComponent {
  constructor(   
    dynamicComponents: DynamicComponentsService,
  ) {
    dynamicComponents.register();
  }

}

现在在你代码的任何地方你都可以这样使用它:

dynamicComponents.create('user-icon', {user:{...}});

或者像这样:

const html = `<div class="wrapper"><user-icon class="user-icon" user='${JSON.stringify(rec.user)}'></user-icon></div>`;

this.content = this.domSanitizer.bypassSecurityTrustHtml(html);

(模板):

<div class="comment-item d-flex" [innerHTML]="content"></div>

注意，在第二种情况下，必须传递带有JSON的对象。Stringify，然后再次解析它。我找不到更好的解决办法了。

我有一个简单的例子来展示如何做angular 2 rc6动态组件。

比方说，你有一个动态html template = template1，想要动态加载，首先包装成组件

@Component({template: template1})
class DynamicComponent {}

这里template1作为html，可能包含ng2组件

在rc6中，必须使用@NgModule来包装这个组件。@NgModule，就像anglarJS 1中的module一样，它解耦了ng2应用程序的不同部分，因此:

@Component({
  template: template1,

})
class DynamicComponent {

}
@NgModule({
  imports: [BrowserModule,RouterModule],
  declarations: [DynamicComponent]
})
class DynamicModule { }

(这里导入RouterModule，在我的例子中，有一些路由组件在我的html中，你可以在后面看到)

现在你可以这样编译DynamicModule: this.compiler.compileModuleAndAllComponentsAsync (DynamicModule) ( factory => factory. componentfactories .find(x => x.p omenttype === DynamicComponent)

我们需要把上面的内容放到app. module .ts中来加载，请查看我的app.moudle.ts。 更多详细信息请查看: https://github.com/Longfld/DynamicalRouter/blob/master/app/MyRouterLink.ts和app.moudle.ts
