从网格的行创建列表的最佳方法是什么？

在我的应用程序中有两个拖放网格。

In my app there are two drag and drop grid.

要创建列表，请将行从第一个网格拖动到第二个网格。

To create a list, you drag rows from the first to the second grid.

发送这个服务器列表（第二个网格），然后在另一个网格中显示的最佳方式是什么？

What is the best way to send this list of rows (second grid) for the server to then be displayed in another grid?

我尝试同步并设置Dirty（true），但是不推荐使用Ext.data.Model＃setDirty。

I tried to sync and setDirty (true), but "Ext.data.Model # setDirty" is deprecated.

    var grid = this.lookupReference('gridRef');
    var store = grid.getStore();
    store.each(function(record){
        record.setDirty(true);
    });

    store.sync();

我尝试，失败：

    var grid = this.lookupReference('gridRef');
    var store = grid.getStore();
    grid.getSelectionModel().selectAll(); 
    var selection = grid.getSelectionModel().getSelection();
    var values = [];

    for(var i=0; i<selection.length; i++) {
        values.push(selection[i].get('order'));
        values.push(selection[i].get('item'));
    }

     var model = Ext.create('app.myModel', values);
     console.log(model) //show just one item
     ????

EDITED：

    var grid = this.lookupReference('gridRef');
    var store = grid.getStore();        

    var records = store.getRange();

    var create = 'create'; //PHP CRUD » case create

    Ext.Ajax.request({
        url: 'php/crudActionList.php?create',
        method: 'POST',
        params : create,
        jsonData: records,
       // jsonData: Ext.encode(records),
       // jsonData: Ext.JSON.encode(records),
        success: function(conn, response, options, eOpts) {
               console.log('Success!');
        },
        failure: function(conn, response, options, eOpts) {
           console.log('failure')
        }
    });
