Question

尝试在此之后使用ng2-autocomplete： - https://www.npmjs.com/package/ng2-completer

我不断得到不同的错误，每次我尝试在stackoverflow或github上找到的解决方案时，我最终会遇到更多错误。请帮我解决这个问题，我对Angular很新，有可能我做了一些根本错误的事情。

我看到的当前错误：

Unhandled Promise rejection: Template parse errors:
Can't bind to 'datasource' since it isn't a known property of 'ng2-completer'.

app.component.ts

import { Component } from '@angular/core';
import { CompleterService, CompleterData } from 'ng2-completer';

@Component({
  selector: 'app-component',
  template: `<h1>Search color</h1>
            <ng2-completer [(ngModel)]="searchStr" [datasource]="dataService" [minSearchLength]="0"></ng2-completer>
            <h1>Search captain</h1>
            <ng2-completer [(ngModel)]="captain" [datasource]="captains" [minSearchLength]="0"></ng2-completer>`
})
export class AppComponent {

  protected searchStr: string;
  protected captain: string;
  protected dataService: CompleterData;
  protected searchData = [
    { color: 'red', value: '#f00' },
    { color: 'green', value: '#0f0' },
    { color: 'blue', value: '#00f' },
    { color: 'cyan', value: '#0ff' },
    { color: 'magenta', value: '#f0f' },
    { color: 'yellow', value: '#ff0' },
    { color: 'black', value: '#000' }
  ];
  protected captains = ['James T. Kirk', 'Benjamin Sisko', 'Jean-Luc Picard', 'Spock', 'Jonathan Archer', 'Hikaru Sulu', 'Christopher Pike', 'Rachel Garrett' ];

  constructor(private completerService: CompleterService) {
    this.dataService = completerService.local(this.searchData, 'color', 'color');
  }
}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule,ReactiveFormsModule } from '@angular/forms';
import { AppComponent } from './app.component';

@NgModule({
imports: [ BrowserModule, FormsModule ],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})

export class AppModule { }

systemjs.config.js （我在这里添加了ng2-completer）

/**
 * System configuration for Angular samples
 * Adjust as necessary for your application needs.
 */
(function (global) {
  System.config({
    paths: {
      // paths serve as alias
      'npm:': 'node_modules/'
    },
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      'app': 'app',

      **'ng2-completer': 'node_modules/ng2-completer/ng2-completer.umd.js',**

    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        defaultExtension: 'js',
        meta: {
          './*.js': {
            loader: 'systemjs-angular-loader.js'
          }
        }
      },
      rxjs: {
        defaultExtension: 'js'
      }
    }
  });
})(this);

Answer 1

我能够解决这个问题： -

完成了两项更改

1。）app-component中的选择器必须是index.html中使用的标记。这很重要。

2。）在模块文件中： -

从“ng2-completer”导入{Ng2CompleterModule};加入并且在NgModule的import []中添加Ng2CompleterModule以及

无法使用ng-autocomplete 2
