DataGrid 可编辑表格验证必填项有无填写

 onBeforeSave:beforesave,

-----------------------------------

function beforesave(index) {

var mc = $('#menulist').treegrid('getEditors', index)[0].target.val();

var fwq = $('#menulist').treegrid('getEditors', index)[1].target.combobox('getValue');}

注意：次处下标是DataGrid 编辑列的个数下标，如果有列没有编辑将不计数跳过
