无法在煎茶中获得对表格的参考

Question

我正在尝试通过单击按钮重置表单。 按钮的功能在文件单独的控制器文件中定义。 但是在单击按钮重置时我得到错误 “未捕获的 TypeError：对象 form1orig 没有方法‘reset’”

Controller
    Ext.define('myapp.controller.form1', {
    extend: 'Ext.app.Controller',
    requires: [
    'myapp.view.form1'
    ],
    config: {
        refs: {
        form1orig: '#pressc',
        form1Submit: 'button[action=sub]',
        form1Reset: 'button[action=res]'
          },
    control: {
    'form1Reset' : {
      tap: 'onForm1Reset'
    },
  'form1Submit' : {
      tap: 'onForm1Submit'
    }     
    }
},

onForm1Reset: function(button){
  'form1orig'.reset();
  console.log('Tapped reset');

},
  onForm1Submit: function(button){

console.log('Tapped submit');

}

});

你应该这样做：

var form = Ext.ComponentQuery.query('form1Me');
form.reset();
