Here is an example of accessing the all Recurrence Event from calendar List using the JavaScript:

<script type="text/javascript">
    $(document).ready(function () {
    debugger;
    $(".readItem").click(function(){
    var html="";
    var script = document.createElement("script");
    script.type = "text/javascript";
    script.src = "/sites/demo/Style%20Library/cascade/jquery.SPServices-2014.02.min.js"; 
    document.getElementsByTagName("head")[0].appendChild(script);
    var start = new Date();debugger;
    $().SPServices({
                    operation: "GetListItems",
                    async: false,
