Question

分页在我的代码中正常工作。但是下一个和上一个按钮分开工作。当我直接访问最后一页时，如果我点击上一个按钮它应该显示上一页。但我在我的代码中做了一些错误任何人都可以指出那？

$(document).ready(function(){
                var table =  $('#myTable');
                var max_size=userDetails.length;

                var pageNum=1;
                var elements_per_page = 3;
                var limit = elements_per_page;
                 $('.paginationList').append('<input type="text" class="btn col-lg-11 col-md-11 col-xs-12" id="pageNo">');
                 $('.paginationList input').val(pageNum);
                pagination(sta,limit);
                $('#nextValue').click(function(){
                    var starting_row = limit;
                    if(max_size>=starting_row) {
