角4-如何正确导入fancytree

Question

我正试图将fancytree导入到我的角4项目中。我按照这样的指示做了所有事情：https://github.com/mar10/fancytree/wiki/TutorialIntegration#howto-run-fancytree-with-angular-4

但最终每次我犯错误

$(.).fancytree不是函数

这条指令中缺少什么东西吗？

我到现在为止所做的：

1. npm安装--保存jquery jquery.fancytree
2. 将脚本和样式添加到角-cli.json中：

[...]
"styles": [
        "../node_modules/bootstrap/dist/css/bootstrap.min.css",
        "../node_modules/ngx-bootstrap/datepicker/bs-datepicker.css",
        "../node_modules/jquery.fancytree/dist/skin-win8/ui.fancytree.min.css",
        "styles.scss"
      ],
      "scripts": [
        "../node_modules/jquery/dist/jquery.min.js",
        "../node_modules/bootstrap/dist/js/bootstrap.min.js",
        "../node_modules/jquery.fancytree/dist/jquery.fancytree-all-deps.min.js"
      ],
[...]

1. 在tsconfig.app.json中添加类型：

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "module": "es2015",
    "baseUrl": "",
    "types": ["jquery","jquery.fancytree"]
  },
  "exclude": [
    "test.ts",
    "**/*.spec.ts"
  ]
}

1. 在组件的html中添加了树id：

<div id="tree">

</div>

1. 尝试在组件中使用：

import { Component, OnInit, Output, EventEmitter } from '@angular/core';
// const fancytree = require('jquery.fancytree'); // doesn't work
import * as $ from 'jquery';

@Component({
  selector: 'table-of-content',
  templateUrl: './table-of-content.component.html',
  styleUrls: ['./table-of-content.component.scss']
})
export class TableOfContentComponent implements OnInit {

  @Output() isTocClosed: EventEmitter<boolean> = new EventEmitter<boolean>();

  constructor() { }

  ngOnInit() {
    $('#tree').fancytree({
      extensions: ['edit', 'filter'],
      source: [
        { title: "Node 1", key: "1" },
        {
          title: "Folder 2", key: "2", folder: true, children: [
            { title: "Node 2.1", key: "3" },
            { title: "Node 2.2", key: "4" }
          ]
        }
      ]
    });

    // const tree = fancytree.getTree('#tree');
  }

}

好了找到了！这些是组件中真正需要的：

import 'jquery.fancytree/dist/modules/jquery.fancytree.edit';
import 'jquery.fancytree/dist/modules/jquery.fancytree.filter';

或者如果有人喜欢：

require('jquery.fancytree/dist/modules/jquery.fancytree.edit');
require('jquery.fancytree/dist/modules/jquery.fancytree.filter');

并在我们需要的组件中使用fancytree对象：

const fancytree = require('jquery.fancytree');
