How Do I add this javascript and HTML code into an angular project ? I have placed the func.js in a src folder in my angular project and in my app.component.ts file where I tried to import and use ngAfterViewInit() to load and use the javascript functions
These are the javascript and html files I am trying to add to the angular web app:
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) {
