easyui的datagrid中行内编辑使用数据联动。即：当编辑产品编号时，该行的产品名称自动根据产品编号显示出来。
在编辑中获取当前行的索引
function getRowIndex(target) { var tr = $(target).closest('tr.datagrid-row'); return parseInt(tr.attr('datagrid-row-index')); }
在编辑中获取当前行的值
var editor = $('#tt').datagrid('getEditors', rowIndex); return $(editor[0].target).numberbox('getValue');
