在我的用户界面中，我有一个 EditorGridPanel 和三个按钮，即:“添加”、“保存”和“取消”。目前，每当我想编辑网格中的现有数据并单击保存按钮时，它都会自动更新数据，这就是我的问题。我想要的是添加一个警报消息框，上面写着“您想保存更改吗？”如果是，则继续执行保存功能。如果否，则在更新网格中的数据之前返回其原始形式的数据。
有人可以帮我解决这个问题吗？
这是我的代码:

Ext.getCmp('b_save').enable();

grid.stopEditing();

grid.startEditing(0, 1);

最佳答案
要显示确认对话框，您可以使用Ext.MessageBox.confirm()方法。
然后，如果用户单击是按钮，您可以调用store.sync()方法或处理您自己的更改保存。
如果用户点击否按钮，您可以调用Ext.data.Store rejectChanges()方法。此方法拒绝所有已修改记录上的未完成更改，并重新插入本地删除的任何记录。
{
text: 'Save',
iconCls: 'save',
id: 'b_save',
disabled: true,
handler : function(){
var store = Ext.getCmp("maingrid").getStore();
Ext.MessageBox.confirm('Save changes', 'Do you want save changes?', function(btnId) {
if (btnId == 'yes') {
// Your current save button handler code
} else {
store.rejectChanges();
}
});
}
}
