jqgrid 加载时第一页面只显示多少条数据

function initGrid() {
        localGrid = jQuery("#tbList");
        localGrid.jqGrid({
            data: localData,
            datatype: "local",
            gridview: true,
            height: ,
            width: '90%',
            rowList: [,],
            colNames: innerColumns,
            autowidth: true,
            hoverrows: false,
            multiselect: false,
            colModel: [
             { name: 'Id', index: 'Id', width: , hidden: true },
             { name: 'Status', index: 'Status', width:  },
            { name: 'GroupName', index: 'GroupName', width:  },
            { name: 'LetterNumber', index: 'LetterNumber', width: , align: "center" },
            { name: 'ApplyUnitName', index: 'ApplyUnitName', width: , align: "center" },
            { name: 'StayDays', index: 'StayDays', width: , align: "center" },
            { name: 'LeaderName', index: 'LeaderName', width: , align: "center" }

            ],
            emptyrecords: "没有任何数据",
            pager: "#pager",
            viewrecords: true,
            rownumbers: true,
            loadonce: true,
            grouping: true,
            rowNum:,
            groupingView : {
                groupField: ['Status']
            },
            ondblClickRow: function (id) {
                //editInfo(id);
            },
            caption: "团组信息"

        }).navGrid('#pager', { edit: false, add: false, del: false, searchtext: "搜索" }, {}, {}, {}, { search: true, sopt: ['cn', 'eq', 'ge', 'gt', 'le', 'lt'] });

    }

加载时只显示5条数据， 就是通过 rowNum:5 这一属性实现的，当然此时你最好也将 rowList 的最少值设为 5   我这里是rowList :[5,10]
