How to hide the recurring calendar list and all-day event Columns

As required by the project, duplicate and all-day event columns need to be hidden, and the list settings cannot be hidden, nor can the list be hidden by using SharePoint manager2013. For example:

Here, jquery is used to hide newform. aspx of the calendar, for example:

Add the webpart of the [Content Editor] after opening, for example:

Edit html

<script src="/_layouts/15/JunHe_Master/js/jquery-1.9.1.js" type="text/javascript"></script><script type="text/javascript">
         _spBodyOnLoadFunctionNames.push("hideall");
        function hideall()
        {
Hidefield ("repeated ");
Hidefield ("all-day events ");
         }
        function HideField(title)
        {
            $(".ms-formtable").find("h3 nobr").each(function () {                
                var text = $(this).text();
                if(text==title)
                {
                       $(this).parent().parent().parent().hide();
                }
            })    
        }
    </script>
Edit editform. aspx in the same way,

Display page dispform. aspx Add the following JS

<script src="/_layouts/15/JunHe_Master/js/jquery-1.9.1.js" type="text/javascript"></script><script type="text/javascript">

        function hideall()
        {
Hidefield ("repeated ");
Hidefield ("all-day events ");
         }
        function HideField(title)
        {
            $(".ms-formtable").find("h3").each(function () {                
                var text = $(this).text();
                if(text==title)
                {
                       $(this).parent().parent().hide();
