Ext.grid.Panel从tbar按钮获取所选记录

Question

我创建了一个View extend Ext.grid.Panel并附加了一个tbar,在工具栏中我得到了2个按钮[Add]和[Remove]在这个问题中我只专注于[Remove]命令.

像往常一样,我想抓住我要删除的网格中当前选定的记录.

所以在控制器中:

init: function() {
 this.control({
   'extendgridlist button[action=remove]': {
      click: this.removeCurrentRow;
    }
 });
}

removeCurrentRow: function(t){
 // how do i get current selected record
}

Answer 1

removeCurrentRow: function(t){
 var grid = t.up('gridpanel');
 var arraySelected =grid.getSelectionModel().getSelection();
 //assuming you have a single select, you have the record at index 0;
 var record = arraySelected[0]
}
