推荐答案

您的问题和代码不匹配.

您在文本控件中说了一些垃圾值.您没有在这里放置任何内容.上面的代码只是基于在受益类型"下拉列表中选择的值来显示按钮.

有什么问题?

Your Question and code does not match.

You say some garbage value in text controls. There is none here that you had put up. The above code simply shows the button based on the value selected in the ''benefittype'' dropdown.

Whats the issue?
