here am unsing sharepoint calender to display events. The calender list is inhereted from event content type. for every event there are several columns like event name, event link(URL), Event Date...etc. for some events there may be some url in link column some may be empty. So in calender if i click the event, suppose if that event has the LINK with url then i have to redirect to the new url, if the link url is empty then i have to redirect to the event url. here when am clilcking on anchor tag in calender am calling a rest api function to get the link value of that event. am checking the link value , if value in null then am redirecting to event details and the value is not null then am redirecting to the link which am get from rest api call. here am using two mail functions which are 1)e.stopPropagation(); means it will stop the redirecting value which is assigned initially. 2)e.preventDefault(); means it will stop the default value of the anchor tag href value.
