jqGrid的请求只请求一次的问题

如题：

       用jqGrid请求表格数据时，只有第一次请求生效，后来的请求就不会再次回显到table中了，只有刷新页面后才会再次。可能是因为为了提高数据的利用，不多次请求后台，解决方法在这个加载之后加一个重新加载操作，确保每次请求都会加载。

没加之前（不可以重复加载）：

$("#jqGrid1").jqGrid({ url: baseURL + 'sys/wpgroundlockevent/personList/'+id, datatype: "json", colModel: [ {label: '事件时间', name: 'createTime', index: 'id', width: 20}, {label: '事件类型', name: 'eventType', index: 'car_group_name', width: 40}, {label: '设备id', name: 'groundLockId', index: 'type', width: 20}, ], viewrecords: true, height: 385, rowNum: 20, width:tab_width, rowList: [20, 40, 60], rownumbers: true, rownumWidth: 70, autowidth: false, multiselect: true, pager: "#jqGridPager1", jsonReader: { root: "page.list", page: "page.currPage", total: "page.totalPage", records: "page.totalCount" }, prmNames: { page: "page", rows: "limit", order: "order" }, gridComplete: function () { // 隐藏grid底部滚动条 $("#jqGrid").closest(".ui-jqgrid-bdiv").css({"overflow-x": "hidden"}); } });

修改后（可以重复加载）：

$("#jqGrid1").jqGrid({ url: baseURL + 'sys/wpgroundlockevent/personList/'+id, datatype: "json", colModel: [ {label: '事件时间', name: 'createTime', index: 'id', width: 20}, {label: '事件类型', name: 'eventType', index: 'car_group_name', width: 40}, {label: '设备id', name: 'groundLockId', index: 'type', width: 20}, ], viewrecords: true, height: 385, rowNum: 20, width:tab_width, rowList: [20, 40, 60], rownumbers: true, rownumWidth: 70, autowidth: false, multiselect: true, pager: "#jqGridPager1", jsonReader: { root: "page.list", page: "page.currPage", total: "page.totalPage", records: "page.totalCount" }, prmNames: { page: "page", rows: "limit", order: "order" }, gridComplete: function () { // 隐藏grid底部滚动条 $("#jqGrid").closest(".ui-jqgrid-bdiv").css({"overflow-x": "hidden"}); } }); // 进行多次加载 $("#jqGrid1").jqGrid("clearGridData"); $("#jqGrid1").jqGrid("setGridParam",{ url: baseURL + 'sys/wpgroundlockevent/personList/'+id, datatype: "json", mtype: "post" }).trigger("reloadGrid");
