如图所示，我想通过Jqgrid提供的分页来实现对数据库的增删改查，通过url来传递修改的值（即文本域中的内容），但是怎么也取不到，请达人指教！(点击submit按钮时发出一个Ajax请求，将文本域中的值传到后台，处理后将处理后的数据传回页面并刷新)

源代码：

    jQuery("#jqNoteAdmin").jqGrid({

        data: mydata,

        datatype:"local",

        width:'100%',

        colNames: ['Message', 'User', 'Date'],

        colModel: [

        { name:'note', index: 'note', width: '70%', sortable: false, editable:true, edittype: "textarea", editoptions: { rows: "8", cols: "60"} },

   { name:'alias', index: 'alias', width: '13%', editable: false },

   { name:'invdate', index: 'invdate', width: '13%', editable: false, editrules:{ required: true} },

   ],

        rowNum: 5,

        rowList: [10, 15, 20],

        pager:'#pagernav',

        sortname:'id',

        viewrecords:true,

        sortorder:"desc"

    });

    jQuery("#jqNoteAdmin").jqGrid('navGrid', '#pagernav',

        { view:true }, //options

        {height: 290, width: 600, url:'/IG/GetCore', onclickSubmit: function (params) { var gr = jQuery("#jqNoteAdmin").jqGrid('getGridParam', 'selrow'); if (gr != null) jQuery("#jqNoteAdmin").jqGrid('editGridRow', gr, { height: 280, reloadAfterSubmit: false }); }, reloadAfterSubmit: false, jqModal: false, closeOnEscape: true, bottominfo: "Fields marked with (*) are required"

    },// edit options

        {height: 290, url:'/IG/IGDetail?kpiName=' + $("#note").text(), width: 600, reloadAfterSubmit: true, jqModal: false, closeOnEscape: true, bottominfo: "Fields marked with (*) are required", closeAfterAdd: true

    },// add options

        {reloadAfterSubmit:false, jqModal: false, closeOnEscape: true },

        { closeOnEscape:true }, // search options

        {height: 290, width:'auto', jqModal: false, closeOnEscape: true }

        );

    ResetGrid("jqNoteAdmin");

});
