当我按下保存按钮时，它工作正常。但是当我在此字段上按 Enter 时遇到一些问题，错误消息是 this.up(...).down(...) 为空。下面给出了我的来自窗口。我只是想，当您在文本框上按 Enter 时，它会像您单击按钮一样。

任何人都可以帮忙吗？

我的控制器在下面给出

Ext.define('${pkgName}.C01I002001', {
    extend  : 'Ext.app.Controller', 
    requires: [],

    views:[
        'V01I001000',

    ],
    refs    : [{
            ref : 'v01i002001',
            selector: 'window'
        }],
    init: function() {
        manuStore   = Ext.data.StoreManager.get('S01I002001'); 
        var me      = this;
        me.category = undefined;        
        me.control({             
            'sv01i00200201 button[action=save]': {
                click           :   this.manufacturerSave
            }
        });
    },
    manufacturerSave   :   function(button){
        win     = button.up('window'),
        form    = win.down('form'),
        record  = form.getRecord(),
        values  = form.getValues();

        if(form.getForm().isValid()){

            var manufacturer    = Ext.create('${appName}.model.M01I002001',{
                name:values.name
            });        

            manufacturer.save({
                scope:this,
                success:function(records, operation){
                    var text     = operation.response.responseText,
                    json         = Ext.decode(text);
                    form.loadRecord(records);
                    controller000.statusbar('sv01i00200201', json.message, 'saveInfo', 'activecaption');
                    manuStore.load();
                    var win       = Ext.getCmp('sv01i00200201');
                    controller000.closeWindow(win);
                },

                failure:function(model, operation){
                    controller000.statusbar('sv01i00200201', operation.error, 'warnInfo', 'red');
                } 
            }); 
        }else{
            controller000.statusbar('sv01i00200201', 'Necessary Field Required', 'warnInfo', 'red');

        }
    }
});

this.up()仅针对您的字段的直接父级（表单面板）通过一个级别冒泡。请尝试以下选项之一：

this.up().up().down('button[action=save]').fireEvent('click');
this.up('window').down('button[action=save]').fireEvent('click');
this.up('#sv01i00200201').down('button[action=save]').fireEvent('click');

看看文档；）

第 2 部分：“button.up 不是函数”

我想我明白了，您必须手动将按钮作为参数传递给fireEvent函数：

var button = this.up('window').down('button[action=save]');
button.fireEvent('click', button);

最后我通过创建 id 来做到这一点

 Ext.get('save-sv01i00200201').dom.click();

按钮修改并创建 id

{
        text    : 'Save',
        icon    : "${resource(dir: 'images', file: 'SAV01004.png')}",
        id      : 'save-sv01i00200201',
        action  : 'save'
    }
