这个方法是BaseForm的一个公用方法,用法比较常用,之前没有想过要专门的去讲这么个方法的运用,但看到官方实例里面也有详细的讲这个方法的具体应用,而且我觉得是比较实用的方法!从BaseForm的角度出发,他一个是所有form组件的基类,实用他的这个方法同样可以用到其子类上,比如FormPanel,我这里就是通过FormPanel来实现这个功能的!
我整理是把grid里面的数据加载到form表单中相对应字段中去!
RowSelectionModel是表示行选择模式CellSelectionModel就表示单元格选择模式
由于前面也有涉及到grid相关知识,这里能理解就行,后面会做详细讲解,同时RowSelectionModel其相对的时间则有rowselect,表示选择当前行的动作!
重点是rowselect: function(sm, row, rec) {Ext.getCmp("user_info").getForm().loadRecord(rec);}这句代码sm是选择模式row是所列的唯一ID,比如第一条记录这个值就是0,以此递推!rec就表示本条记录
