我有一个用户网格。要删除一个，请选择您的行并单击“删除”按钮。但是，这行不通。我的代码是：

It is good practice to always check hasSelection()like -
总是hasSelection()像这样检查是一种很好的做法-
if (userGrid.getSelectionModel().hasSelection()) {
var row = userGrid.getSelectionModel().getSelection()[0];
console.log(row.get('dni'))
}

perhaps because
也许是因为

getSelection() : Ext.data.Model[]
