我正在使用 Spring、Spring-JS 和 DoJo(dijit) 进行我的第一个项目，并且基于以下编码示例，我有两个问题。

1) 如何检查 Dojo (dijit) 电话号码字段的大小是否正确，以及如何检查姓名字段是否大于 3 且小于 50？

2）如您所见，我的表单有单选按钮，我需要根据需要进行设置。我如何使用 Dojo (dijit) 做到这一点。

谢谢

所以这是单选按钮的答案，举个例子：

Spring.addDecoration(new Spring.ElementDecoration({
      elementId : 'A',
      widgetType : "dijit.form.RadioButton",
      widgetModule : "dijit.form.CheckBox",
      validate: function (){
           if(dojo.query('INPUT[name=type]', 'customer').filter(function(n){return n.checked;}).length > 0){return true;} else {alert('choose a type');return false;}
      },
      widgetAttrs : ...
}));

现在您应该可以对您的姓名字段执行相同的操作
