Question

添加newRecord时出现问题，控制台始终输出[]。

请帮帮我。

_storePR2.add(_key.data);
_storePR2.commitChanges();
var newRecord = _storePR2.getNewRecords();
console.log('newRecord',newRecord);

输出：newRecord []

这个我的控制器操作按钮选择：

var me = this;
var _panel = me.getMainPanel();
var _tabpanel = _panel.down('#tabmaintain');
var _activetab = _tabpanel.getActiveTab();
var _window = button.up('window');
var _grid = _window.down('grid');
//var _girdd = this.getPanelSearch();
//var _grids = _girdd.down('grid');
var _gridSelected = _grid.getSelectionModel().getSelection();
//var row = _grid.store.indexOf(_gridSelected);
//console.log(row);
console.log(_gridSelected);
console.log(_grid);
//console.log(_girdd.down('grid'));
//selected=[];

//Check selected product
if(_gridSelected.length===0){
    Ext.Msg.alert('Warning','Please select product');
    return;
}

//Submit Product
var _gridPR = _activetab.down('#detailProduct');
var _storePR2 = _gridPR.getStore();
//console.log(_storePR2.data);
Ext.Array.each(_gridSelected,function(_key,_value,item){
    //console.log(selected.push(item));
    _validate = true;
    _storePR2.each(function(_storeData,_storeIndex){
        console.log(_key.data);
        if(_storeData.data.no_po === _key.data.no_po){
            _validate = false;
            Ext.Msg.alert('Warning','The Product had been picked');
            return;
        }
    });
    if(_validate){
        // Add record to the store by data
        _storePR2.add(_key.data);


        // Get array of new records from the store
        var newRecords = _storePR2.getNewRecords();
        console.log('newRecord',newRecords);

         // Commit changes after getting new records
        _storePR2.commitChanges();



        _window.close();
    }
});

Answer 1

这是因为您提交了更改，因此不再有任何新记录＆＃39;。

在提交更改之前尝试获取新记录：

// Add record to the store by data
_storePR2.add(_key.data);

// Get array of new records from the store
var newRecords = _storePR2.getNewRecords();
console.log('newRecord',newRecords);

// Commit changes after getting new records
_storePR2.commitChanges();

这是fiddle。

Answer 2

首先，您需要添加记录来存储和提交更改，然后获取新记录。

 grid_store.add({'Name':"ab",'dob':"099"})
     grid_store.commitChanges();
     var newRecord = grid_store.getNewRecords()
     console.log('newRecord',newRecord);
 });

为什么添加newRecord []为空
