Question

我正在尝试在RowEditing Update上更新商店点击

添加了一个监听器

 listeners: {                                            
               'edit': function (editor, e) { 
                    alert('Row Updating');
                 }
            }

警告在UPdate点击时触发，因此尝试现在更新商店，如下所示

1.var rec = e.record;                                                
  e.store.sync();

2. var timeGrid = this.up('grid');
   timeGrid.store.sync();

3. Ext.ComponentQuery.query('#gdItemId')[0].store.sync();

4. this.store.sync();

以上所有内容都无法更新要存储的已更改记录。抛出错误为 -

Unhandled exception at line 1984, column 17 
0x80004005 - JavaScript runtime error: unknown exception

原因是什么？请建议我，我如何在这里更新数据。

 Ext.define('TimeModel', {

    var r = Ext.create('TimeModel', {
        stop_type_id: 1
    });
    timeGrid.store.insert(0, r);
    rowEditingTime.startEdit(0, 0);        
}
} ],                                      
listeners: {                                            
'edit': function (editor, e) {
    //alert('Updating');
    //var rec = e.record;                                                
    //e.store.sync();
    //var timeGrid = this.up('grid');
    //timeGrid.store.sync();
   // Ext.ComponentQuery.query('#gdTimeCommitmentItemId')[0].store.sync();
    //this.store.sync();
}

在您的问题中包含您的商店代理类。我认为您没有正确创建商店代理。

示例存储同步的代理

   proxy : 
{
    type : 'ajax',
    reader : 
    {
        root : 'data',
        type : 'json'
    },
    api : 
    {
        read : '/ExampleService.svc/students/',
        create: '/ExampleService.svc/createstudentbatch/',
        update : '/ExampleService.svc/updatestudentbatch/',
        destroy : '/ExampleService.svc/deletestudentbatch/'
    },
    actionMethods : 
    {
        destroy : 'POST',
        read : 'GET',
        create : 'POST',
        update : 'POST'
    }}
