Angular: minicalendar not work

When using dhtmlxScheduler with Angular, the mini calendar does not work.

I followed the instructions here

But when I click on the mini calenadar icon, I get this error (in the Chrome console):

dhtmlxscheduler_minical.js:10 Uncaught ReferenceError: getOffset is not defined at Object.scheduler.renderCalendar (dhtmlxscheduler_minical.js:10) at show_minical (<anonymous>:7:19) at HTMLDivElement.onclick (VM4641 scheduler:27) scheduler.renderCalendar @ dhtmlxscheduler_minical.js:10 show_minical @ VM4573:7 onclick @ VM4641 scheduler:27

I use dhtmlxScheduler 4.4.9

How to correct this problem?
Thanks in advance


I am experiencing the same issue, did you find a solution?

I have an Angular 5 app.

I am using the PRO evaluation version and installed it by copying the package.json from the opensource version into the evaluation folder and running yarn add file:/path-to-file.

In my component, I have:

import "dhtmlx-scheduler";
import "dhtmlx-scheduler/codebase/ext/dhtmlxscheduler_timeline";
import "dhtmlx-scheduler/codebase/ext/dhtmlxscheduler_minical";

showMinical() {
        if (this.scheduler.isCalendarVisible()) {
        } else {
                position: "dhx_minical_icon",
                date: this.scheduler._date,
                navigation: true,
                handler: function (date, calendar) {

And in my html I have:

<div #scheduler_here class="dhx_cal_container" style="width: 100%; height:100vh">
    <div class="dhx_cal_navline">
        <div class="dhx_cal_prev_button">&nbsp;</div>
        <div class="dhx_cal_next_button">&nbsp;</div>
        <div class="dhx_cal_today_button"></div>
        <div class="dhx_cal_date"></div>
        <div class="dhx_cal_tab" name="timeline_tab" style="right:280px;"></div>
        <div class="dhx_minical_icon" id="dhx_minical_icon" (click)="showMinical()">&nbsp;</div>
    <div class="dhx_cal_header"></div>
    <div class="dhx_cal_data"></div>

The calendar icon appears and when I click it, showMinical() is triggered but it then returns the error in the original poster’s post:

ERROR ReferenceError: getOffset is not defined

Does anyone have any ideas?

Extensions of dhtmlxScheduler must be included only after the core file dhtmlxsheduler.js
When you are working with script includes it means that you are adding a script tag for dhtmlxscheduler.js first, and script tags for extensions after that.

In case of import, the situation is a more complicated, as import doesn’t guarantee that imported sources will be processed in the defined orders. If you are using webpack – try to use script-loader for scheduler’s file, which will preserve an order of includes and will fix the issue.
