<div id="example">
<div id="scheduler"></div>
</div>
<script>
$(function() {
$("#scheduler").kendoScheduler({
date: new Date("2022/6/13"),
startTime: new Date("2022/6/13 07:00 AM"),
height: 600,
views: [
"day",
{ type: "workWeek", selected: true },
"week",
"month",
"agenda"
],

batch: true,

dataType: "jsonp"
},
destroy: {
url: "https://demos.telerik.com/kendo-ui/service/tasks/destroy",
dataType: "jsonp"
},
parameterMap: function(options, operation) {
if (operation !== "read" && options.models) {
return {models: kendo.stringify(options.models)};
}
}
},
schema: {
model: {
id: "taskId",
fields: {
taskId: { from: "TaskID", type: "number" },
title: {
from: "Title",
defaultValue: "No title",
validation: {
required: true,
custom: function(input) {
if (input.prop("name") === "title") {
if (!remoteValidator.initiated) {
remoteValidator.check(input, this);
input.attr("data-custom-msg", "checking...");
return false;
}
input.attr("data-custom-msg", "Not valid!");
return remoteValidator.valid;
}
return true;
}
}
},

end: { type: "date", from: "End" },

]
}
]
});
var remoteValidator = {
valid: false,
initiated: false,
check: function(element, validator) {
remoteValidator.initiated = true;
// Simulate Ajax.
setTimeout(function() {
// TODO: set to true if valid
// remoteValidator.valid = true;
validator.validateInput(element);
remoteValidator.initiated = false;
}, 1000);
}
};
});
