How to load the ng-template in separate file?

问题

In below sample, I have used ng-template like below and it is working fine.

Sample link: click here

<ng-template #template let-dataSource="">
  <span *ngIf="dataSource.iconCss" class="e-menu-icon {{dataSource.iconCss}}"></span> {{dataSource.header}} {{dataSource.text}}
  <span *ngIf="dataSource.templateHeader" class="e-login-content">
        <button ejs-button cssClass="e-info">Sign In</button>
      </span>
</ng-template>

But I want to create a new file for ng-template content and I want to use it in another file. I have tried like below but not working. Please help me find a solution for this case.

template.html

<ng-template #template let-dataSource="">
  <span *ngIf="dataSource.iconCss" class="e-menu-icon {{dataSource.iconCss}}"></span>
  {{dataSource.header}} {{dataSource.text}}
  <span *ngIf="dataSource.templateHeader" class="e-login-content">
    <button ejs-button cssClass="e-info">Sign In</button>
  </span>
</ng-template>

default.html

<div class="control-section">
  <ejs-menu #menu [items]='dataSource' [fields]='menuFields'>
    <ng-container *ngTemplateOutlet="template;"></ng-container>
  </ejs-menu>
</div>

回答1:

You can have a component for your templates (name it tplComponent) and inside that, create as many templates as you want. Then in other components, get an instance of tplComponent and get the template from that. Here is a question that has an example of this approach (I haven't tried that though).

Please let me know if that works.

You can use *ngTemplateOutlet to archive the same

Please refer the link below

Answer:

step1:

i have initialized my template as a new component as like below

template.component.ts

import { Component, Input } from '@angular/core';

@Component({
  selector: 'app-device',
  template: `
  <span *ngIf="dataSource.iconCss" class="e-menu-icon {{dataSource.iconCss}}"></span>
  {{dataSource.header}} {{dataSource.text}}
  <span *ngIf="dataSource.templateHeader" class="e-login-content">
    <button ejs-button cssClass="e-info">Sign In</button>
  </span>
`
})
export class DeviceComponent {
  @Input()
  dataSource: any;
}

Then i have used that component template in my parent component as like below

default.html

<div class="control-section">
	<ejs-menu #menu [items]='dataSource' [fields]='menuFields'>
    <ng-template #template let-dataSource>
      <app-device [dataSource]="dataSource"></app-device>
    </ng-template>
  </ejs-menu>
</div>
