我尝试使用formBind：true
为表单添加验证虽然没有发生验证（保存按钮不是灰色的）。发生了文本字段不为空的验证，但将其绑定到“保存”按钮似乎什么也没做。
如果您双击一条记录，它将显示相关表格。这可以在这里看到：

来自Sencha API文档：
FormPanel中的任何组件都可以使用formBind：true配置。
问题是你在表单组件
之外使用了formBind属性您可以通过以下方式更正代码：
Ext.define("SessionForm", {
extend: 'Ext.window.Window',
alias: 'widget.sessionForm',
// ...
items: [{
xtype: 'form',
items: [{
// your form items
}],
buttons: [{
xtype: 'button',
text: 'Save',
formBind: true,
handler: function (button) {
// also you should rewrite the following line
// to make it independant from the components structure
var form = button.up().up().down('form');
form.updateRecord();
button.up('window').destroy();
}
}, {
xtype: 'button',
text: 'Cancel',
handler: function (button) {
button.up('window').destroy();
}
}]
}]
});
