FAQ in JavaScript (ES5) Schedule control
In this article, you can find some frequently asked questions and corresponding solutions while getting hands-on experience with scheduler control.
Grouping with empty resources
Grouping without providing any resource data will throw the following problems.
- Normal(vertical) views are rendered, but you are not able to perform CRUD operations
- Timeline views not at all render and shows empty scheduler table
So, we suggest to avoid grouping with empty resources in the scheduler.
Not providing e-field in editor template
Error: While using editor template, value of e-field is missing in editor window.

Missing CSS reference

Solution:
The above problem occurs when missing CSS references for the scheduler in a project. You can resolve this issue by providing proper CSS for the scheduler.
<html>
<head>
<title>Syncfusion Javascript Sample</title>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />
<meta http-equiv="x-ua-compatible" content="ie=edge">
<meta name="author" content="Syncfusion" />
<! –– scheduler CSS is referred from this link ––>

</html>QuickInfoTemplate at bottom
When using the quickInfoTemplate in scheduler, sometimes quickinfo popup not shown fully at the bottom area of scheduler. You can resolve this by using cellClick and eventClick events and below code snippet.
var eventAdded = false;
var scheduleObj = new ej.schedule.Schedule({
.
.
cellClick: onClick,
eventClick: onClick
});
scheduleObj.appendTo('#Schedule');
function onClick(args) {
if (!this.eventAdded) {
let popupInstance = document.querySelector('.e-quick-popup-wrapper').ej2_instances[0];
popupInstance.open = () => {
popupInstance.refreshPosition();
};
this.eventAdded = true;
}
}Not processing culture files while using localization
Error Image:
While using locale in scheduler, not processing the loadCultureFiles properly throws the problem.
Solution: Properly add the culture files(numberingSystems, timeZoneNames, loadCldr, L10n etc.,) and loadCultureFiles method in your project will resolve the problem.
loadCultureFiles();
var localeTexts;
var localeAjax = new ej.base.Ajax('./locale.json', 'GET', false);
localeAjax.onSuccess = function (value) {
localeTexts = value;
};
localeAjax.send();
ej.base.L10n.load(JSON.parse(localeTexts));
function loadCultureFiles() {
// Processing culture files
var files = ['ca-gregorian.json', 'numbers.json', 'numberingSystems.json', 'timeZoneNames.json'];
var loader = ej.base.loadCldr;
var loadCulture = function (prop) {
var val, ajax;
ajax = new ej.base.Ajax('./' + files[prop], 'GET', false);
ajax.onSuccess = function (value) {
val = value;
};
ajax.send();
loader(JSON.parse(val));
};
for (var prop = 0; prop < files.length; prop++) {
loadCulture(prop);
}
}
var scheduleObj = new ej.schedule.Schedule({
width: '100%',
height: '550px',
locale: 'fr-CH',
}
});
scheduleObj.appendTo('#Schedule');
