Microsoft SharePoint 365 does not have a direct way to embed javascript for CalendarWiz Website Plugins into a SharePoint web page. Follow these "work around" steps below to embed the Upcoming Events List and Mini Calendar Website Plugins into a SharePoint web page.
With the SharePoint editor open to your web page, position the cursor where you want to insert the CalendarWiz Web Widget.
From the SharePoint menu, choose to insert a Paypal gadget.
Copy the CalendarWiz Web Widget JavaScript code from the Widget's Administration screen (either Upcoming Events List or Mini Calendar).
Paste in the following code, substituting the CalendarWiz Web Widget JavaScript code for the JavaScript code shown in bold below:
Code For Upcoming Events List:
<form action=""><input type="image" style="display:none !important;">
<script type="text/javascript" src=http://www.calendarwiz.com/calendars/ucfeeder.php?crd=yourcalendaridentifier&theme=yourupcomingeventslisttheme>
</script>
</form>
Code For Mini Calendar:
<form action=""><input type="image" style="display:none !important;">
<script type="text/javascript" src=http://www.calendarwiz.com/minical/minical.js?crd=yourcalendaridentifier&mctheme=yourminicalendartheme>
</script>
</form>View your SharePoint web page and you should now see the CalendarWiz Plugin on the page.
Note that this method uses the SharePoint 365 PayPal gadget, not the HTML gadget. Use the HTML gadget if you are inserting your full calendar into the SharePoint 365 web page via in iframe. Currently there is no way to insert the CalendarWiz Event Search Plugin into a SharePoint 365 web page, although the Search button on the full calender embedded via an iframe.
