Description
How can I prevent users from saving an event if they have not selected a day from the weekly recurrence editor in the Kendo UI for jQuery Scheduler?
Solution
To achieve the desired scenario, refer to the following implememtation:
<div id="example">
<div id="scheduler"></div>
</div>
<script>$(function() {
$("#scheduler").kendoScheduler({
edit:function(e){
var scheduler = e.sender;
var shouldDisplayMessage = true;
$(".k-scheduler-update").click(function(e){
if(!$('[aria-label="RepeatNever"]').hasClass("k-active")){
e.preventDefault();
e.stopPropagation();
var buttons = $('.k-recur-weekday-buttons').children();
for(let button of buttons){
if($(button).hasClass("k-active")){
scheduler.saveEvent();
shouldDisplayMessage = false;
}
}
if(shouldDisplayMessage){
$("<div id='valMessage' style='color:red;'>Please select an option</div>").insertAfter($(".k-recur-weekday-buttons"));
shouldDisplayMessage=false;
}
}
})
},
