javascript - 如何自动刷新jqgrid？

Question

我使用以下脚本将 sql 数据库中的详细信息绑定(bind)到 jqgrid。添加、编辑、删除工作正常，我的问题是，如果我尝试添加、编辑、删除数据jqgrid 它在数据库中更新但在我刷新页面然后数据显示在jqgrid中后没有显示在jqgrid中。如何在点击提交按钮后自动刷新jqgrid？

    <script type="text/javascript">


          $(document).ready(function(){
          var mydata=new Array();

                $.extend({
                getValues: function(url) {
                var result = null;

                $.ajax({

                    url: url,
                    type: 'POST',
                    data:'Param=value',
                    async:false,
                    success: function(data) {
                            result=JSON.parse(data);
                             }
                        });
                  return result;
                }

                });

                mydata = $.getValues(Some url);//get the data from the url

           $("#datagrid").jqGrid({
