这个例子展示了使表格可编辑的基本步骤。这样做我们只需要3步:
- 标记Grid的哪一列是可编辑的。这是通过设置一个新属性"editable:true"实现的。
默认grid中所有咧都是不可编辑的。 - 指定服务器需要接收发送的编辑数据的url。这是通过设置"editurl"选项来实现的。
- 使用这三个方法:editRow, saveRow, restoreRow。
editRow(rowid, keys) -接收两个参数:rowid-行的唯一id和列名。当我们调用此方法之后，我们可以使用Enter按键和Esc按键来保存和取消编辑状态。
saveRow( rowid, callback, url, extraparams) - rowid:行的唯一id，callback:自定义方法，他是当我们想服务器发送数据之后来接收数据的方法。url:当我们指定了此参数，我们就会覆盖editurl参数。extraparams :添加我们想服务器发送的一些参数。当这些数据格式化成 id=rowid&name=value…的时候，里面的name就是colModel的中的那么字段。
restoreRow( rowid) -在行编辑之前回复数据到初始值。
提示:由于安全原因，数据不会保存到服务器。
