Jqgrid使用

 $('#mygrid').jqGrid('GridUnload');   //保留table元素
 $('#mygrid').jqGrid('GridDestroy '); //相当于remove，移除包括table元素

grid.jqGrid("saveCell", lastrow, lastcell);//保存单元格，切换为文本模式

var rowIds = grid.jqGrid('getDataIDs');

for (var i = 0, j = rowIds.length; i < j; i++) {
var curRowData = grid.jqGrid('getRowData', rowIds[i]);
}

grid.setGridParam({ cellEdit: allowEdit });
grid.trigger("reloadGrid");

获取所有选中行

var selectRowIds = grid.jqGrid("getGridParam", "selarrrow");
if (selectRowIds.length < 2) 

 var gridColModels = [
    { label: '编号', name: 'Id', index: 'Id', 100, sortable: false, editable: false,  align: 'center', hidden: true },
    { label: '', name: '', index: '',  100, sortable: false, editable: true, align: 'center', edittype: 'text', editrules: { custom: true, custom_func: _dateCheck }, editoptions: { size: 10, maxlengh: 10, dataInit: function (element) { $(element).datepicker({ dateFormat: 'yy-mm-dd' }) } } },

//验证计划时间格式
