Javascript 在ionic 4中使用.js文件

我是爱奥尼亚的新手，我想在一个页面中使用

.js

文件

我有一个

.js

文件，它在画布中创建气泡

我想做的是，在我的爱奥尼亚4项目中使用

.js

文件，并在我的主页上显示bubble

这是我想用的密码笔的密码

我在

'assets/js/bubblefile.js'

中创建了文件，但我不知道如何在我的

home.html

或

home.ts

中使用

'bubblefile.js'

文件？下面是我的代码

已编辑

home.html

code:

<ion-header>
  <ion-toolbar>
    <ion-title>
      Ionic Blank
    </ion-title>
  </ion-toolbar>
</ion-header>

<ion-content>

如果您想在HTML文件中使用它，请多谢：

<script src="assets/js/bubblefile.js"></script>

在要在其中使用的文件顶部：

import "./assets/js/bubblefile";

home.html代码：

      <ion-toolbar>
        <ion-title>
          Ionic Blank

从@sivakumar Answer我得到了一些使用.js文件的技巧

home.html代码：

<ion-header>
  <ion-toolbar>
    <ion-title>
      Music Bubble
    </ion-title>
  </ion-toolbar>
</ion-header>

<ion-content>
  <div id="bubbles">
  </div>
</ion-content>

bubblefile.js代码：

var bubble = (function(){
    var nodes = new vis.DataSet([
        {label: "Pop"},
        {label: "Alternative"},
        {label: "Rock"},
        {label: "Jazz"},
        {label: "Hits"},
        {label: "Dance"},
        {label: "Metal"},
        {label: "Experimental"},
        {label: "Rap"},
        {label: "Electronic"},
    ]);
    var edges = new vis.DataSet();

    var container = document.getElementById('bubbles');
    var data = {
        nodes: nodes,
        edges: edges
    };

    var options = {
        nodes: {borderWidth:0,shape:"circle",color:{background:'#F92C55', highlight:{background:'#F92C55', border: '#F92C55'}},font:{color:'#fff'}},
        physics: {
            stabilization: false,
            minVelocity:  0.01,
            solver: "repulsion",
            repulsion: {
                nodeDistance: 40
            }
        }
    };
    var network = new vis.Network(container, data, options);


    // Events
    network.on("click", function(e) {
        if (e.nodes.length) {
            var node = nodes.get(e.nodes[0]);
            // Do something
            nodes.update(node);
        }
    });
})

有一个用于加载异步JavaScript文件的库。

安装软件包：

npm i scriptjs

然后在任何地方使用它，如下所示：

import { get } from 'scriptjs';

ngOnInit() {

    get("assets/js/searchEmp.js", () => {
        getSerchInspContext = this;
        loadSearchEmp();
    });}`

或

您可以简单地使用jquery方法在头中追加或删除脚本标记

要添加.js文件，请在ngOnInit（）下的下面一行调用：

---

我需要在哪个文件顶部添加最后一行？在你的

bubblefile.js

中添加

export

行，在你想在中使用的任何js文件中添加

bubblefile.js

行。我想在.ts文件中使用它，而不是在js文件中。谢谢你的快速重播，但它给出了错误

/src/app/home/home.page.ts模块未找到：错误：无法解析“/assets/js/bubblefile”in'/Users/atologistimac2/Documents/HybridApps/musicbuble/src/app/home'

与

home.page.ts

文件相关的

文件存储在哪里？检查文件路径如所示更改文件名气泡
npm i scriptjs

import { get } from 'scriptjs';

ngOnInit() {

    get("assets/js/searchEmp.js", () => {
        getSerchInspContext = this;
        loadSearchEmp();
    });}`

$('head').append('<script async src="assets/js/search.js"></script>');

document.querySelector('script[src="assets/js/search.js"]').remove();
