displayed:none => display:none

var input = document.getElementById('text'); 
// your html don't have id='text' 

<input type="text"> => <input id='text' type="text">
显示:无=>显示:无
var input=document.getElementById('text');
//您的html没有id='text'
=> 
那么你必须解决两个问题

my bad,我正在从我的编辑器修复这里的代码,然后我写了显示。谢谢你指出。是的,它说显示根本不起作用。你的代码有两个问题,一个是显示,另一个是id文本字段OK,所以还不能正常工作。你认为我的提交按钮放错地方了吗?还有ShowMenu我该怎么处理它呢?我一直在搞乱代码,因为ShowMenu的javascript中没有变量,所以我把它去掉了。这是我到目前为止所拥有的。。。优惠券兑换请输入您收到的优惠券代码:@nextlevelgamingCO您是否已对blueiur和我提到的所有必要更改进行了更改..如果是,请更新您的code@nextlevelgamingCO你的代码仍然有很多错误。我做了一些更改。检查我的答案,看看它是否有效。。我还将JSFIDLE linkSibu放在这里,我看到它正在工作。但可悲的是,在咖啡杯编辑器中测试它,它似乎恨我或其他什么,哈哈。我把javascript放在头标签里了,对吗?那么剩下的是html吗?我也在使用IE。这可能是问题所在。
