数据源如果有布尔值，那么在UI里，最合适的控件应该就是checkbox了。

easyUI的datagrid中，列的checkbox酱紫设置：

{field:'status',title:'Status',width:50,align:'center',	editor:{		type:'checkbox',		options:{			on: "true",			off: "false"		}	}},

{"total":28,"rows":[	{"productid":"FI-SW-01","unitcost":10.00,"status":true,"listprice":16.50,"attr1":"Large","itemid":"EST-1"},	{"productid":"K9-DL-01","unitcost":12.00,"status":true,"listprice":18.50,"attr1":"Spotted Adult Female","itemid":"EST-10"},	{"productid":"RP-SN-01","unitcost":12.00,"status":true,"listprice":18.50,"attr1":"Venomless","itemid":"EST-11"}]}

这样子就有个问题：

当datagrid里的行处于编辑状态时，checkbox并未能自动带上应有的值，比如本来对应是true，但当checkbox出现时，并没有自动勾选！造成很不好的后果：编辑一次，如果不手动对这个checkbox再打钩一次，那么原本是true，现在就变成了 false ！什么毛病。

对应办法是将数据里的布尔值变为字符串："status":true ==> "status":"true"

{"total":28,"rows":[	{"productid":"FI-SW-01","unitcost":10.00,"status":"true","listprice":16.50,"attr1":"Large","itemid":"EST-1"},	{"productid":"K9-DL-01","unitcost":12.00,"status":"true","listprice":18.50,"attr1":"Spotted Adult Female","itemid":"EST-10"},	{"productid":"RP-SN-01","unitcost":12.00,"status":"true","listprice":18.50,"attr1":"Venomless","itemid":"EST-11"}]}
