如何将这段 JavaScript 和 HTML 代码加入 Angular 项目中？能否在 Angular 中从 JavaScript 函数中呈现 HTML？

Question

如何将JavaScript和HTML代码添加到Angular项目中？ 我将func.js文件放置在我的angular项目的src文件夹中，并在app.component.ts文件中尝试导入并使用ngAfterViewInit（）来加载和使用JavaScript函数。

这些是我尝试添加到Angular Web应用程序的JavaScript和HTML文件：

funcs.js

const uName = 'admin';
const uPass = '12345';
const endpoint = 'http://11.11.111.241:8000';
const resource = {
    questionnaire: 'Questionnaire',
    valueset: 'ValueSet'
}

//get questionnaire
var url = 'http://cihi.ca/fhir/irrs/Questionnaire/abc-abc-community-on';
var quesJson = getData(resource.questionnaire, '?url=' + url);
quesJson = quesJson.entry[0].resource
// saveJsonToFile(quesJson, 'irrsQuesJson');
var copy = $.extend(true, {}, quesJson);
//convert to lhc form
var lformsQ = LForms.Util.convertFHIRQuestionnaireToLForms(quesJson, 'STU3')
// saveJsonToFile(lformsQ, 'lFormJson');
//prepare valuesets
const vsArray = createValueSetData();
//add value sets
injectValueSet(lformsQ);
// saveJsonToFile(lformsQ, 'lFormValueSetInjected');
// Add the form to the page
var options = { 'prepopulate': true };
LForms.Util.addFormToPage(lformsQ, 'formContainer', options);





/////////////////////////////////////////////////////////////////////////////////////////////////////////////
function getData(res, param, log) {
    var data = null;
    var url = endpoint + '/' + res + param;
    $.ajax({
        accepts: {

        },
        beforeSend: function (xhr) {

可能是重复的问题，参考如何在Angular中包含JavaScript脚本文件并从该脚本调用函数？。 - Austin T French

我按照 https://dev59.com/Y1UL5IYBdhLWcg3w-cLr 上的步骤进行操作，但对我来说并没有起作用。 - Amd Deeb

Answer 1

首先通过Angular CLI创建一个新的组件，然后在.ts文件中添加变量声明，即：

const uName = 'admin';
const uPass = '12345';
const endpoint = 'http://11.11.111.241:8000';
const resource = {
    questionnaire: 'Questionnaire',
    valueset: 'ValueSet'
}

//get questionnaire
var url = 'http://cihi.ca/fhir/irrs/Questionnaire/abc-abc-community-on';
var quesJson = getData(resource.questionnaire, '?url=' + url);
quesJson = quesJson.entry[0].resource
// saveJsonToFile(quesJson, 'irrsQuesJson');
var copy = $.extend(true, {}, quesJson);
//convert to lhc form
var lformsQ = LForms.Util.convertFHIRQuestionnaireToLForms(quesJson, 'STU3')
// saveJsonToFile(lformsQ, 'lFormJson');
//prepare valuesets
const vsArray = createValueSetData();
//add value sets
injectValueSet(lformsQ);
// saveJsonToFile(lformsQ, 'lFormValueSetInjected');
// Add the form to the page
var options = { 'prepopulate': true };
LForms.Util.addFormToPage(lformsQ, 'formContainer', options);

然后在 .html 页面中添加 HTML 代码。

    <button onclick="save()">
        Save QuestionnaireResponse
    </button>
    <input type="file" id="file1">
    <button onclick="openQues()">
        Open QuestionnaireResponse
    </button>
    <div id="formContainer"></div>

然后在HTML文件中的`

Answer 2

import { Component, OnInit   } from '@angular/core';
import * as $ from 'jquery';
import {OpenQues,save} from '../assets/scripts.js'


declare var tesing: any;

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})


export class AppComponent implements OnInit {
  title = 'Look jQuery Animation working in action!';

  public ngOnInit()
  {

    $.getScript('./assets/scripts.js');


  }

  public  open()
  {

    OpenQues();

  }


  public save()
  {

    save();

  }



}

这对我有用

谢谢！它可以运行，但需要在npm install --save jquery之前安装以下软件包： npm install --save @types/jquery - Ram
