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在数据库中更新了，但是在我刷新页面之后没有显示在jqgrid中，然后数据显示在jqgrid中。点击提交按钮后如何自动刷新jqgrid？强>

    <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',

  $("#datagrid").trigger("reloadGrid");
