解决方法:
该行为是预期的.问题来自这样一个事实,即新创建的记录没有ID,这就是为什么将它们视为新记录的原因.您可以使用isNew()方法进行检查.
当您取消对新记录(尚未同步)的编辑时,它将被删除.该操作与以下操作相同：按“添加新记录”,然后按“取消”.
这是an example,它演示了如何使用本地数据实现CRUD操作.
transport: {
read: function(o) {
//pass the date
o.success(data);
},
create: function(o) {
var item = o.data;
//assign a unique ID and return the record
counter++;
item.Id = counter;
o.success(item);
},
update: function(o) {
//edit the local array and mark the operation as successful
o.success();
},
destroy: function(o) {
//edit the local array and mark the operation as successful
o.success();
}
}
