在我的UI中，我有一個EditorGridPanel和一個三個按鈕，分別是'add'，'save'和'cancel'。目前，無論何時我想編輯網格中的現有數據並單擊保存按鈕，它都會自動更新數據，這是我的問題。我想要添加一個提醒消息框，說'你想保存更改嗎？'如果是，則繼續執行保存功能。如果爲「否」，則在更新網格中的數據之前返回其原始形式的數據。在Extjs中提示提醒消息框
有人可以幫我解答嗎？
這是我的代碼：
test.js
var grid = new Ext.grid.EditorGridPanel({

disabled: true,
handler : function(){
var Put = grid.getStore().recordType;
var p = new Put({
action_take: 'add',
is_active: '',
allowBlank: false
});
Ext.getCmp('b_save').enable();
Ext.getCmp('b_cancel').enable();
grid.stopEditing();
store.insert(0, p);
grid.startEditing(0, 1);
}

我可以在哪裏插入這個？ – sack
在你的保存按鈕處理程序。 – Akatum
nothings改變，我需要改變你的代碼中的東西嗎？ – sack
