如何在html表单中隐藏文本字段

【中文标题】如何在html表单中隐藏文本字段【英文标题】：How to hide a text field in an html form 【发布时间】：2016-07-11 20:47:42 【问题描述】：我有一个表格，我的团队用来发送信息，他们输入客户的电子邮件地址，然后将其邮寄出去。我设法隐藏了除三个以外的所有字段。
一个字段设置要发送的电子邮件数量。真的很愚蠢，因为不知道为什么有人要向同一个人发送不止一封相同的电子邮件。
另一个只是设置发送的时间延迟或速度。无论如何，它们都是文本框，我想将它们从页面中隐藏起来。 最后一个是纯文本或 html 文本单选按钮。
现在输入字段的顺序很可能很奇怪，因为我只是重新排列了一些东西，所以它可以很好地显示在页面上，而无需重做表格。

【问题讨论】：
这是我的帮助***.com/questions/2362498/… 只是从页面中删除它们？还是让它们隐藏起来？ 和 感谢您的输入，这篇原始帖子询问如何“隐藏”它们。至于将它们删除，我尝试注释掉并且表单停止工作，所以我认为删除它们会做同样的事情。 【参考方案1】：只需应用内联 css i-e style='display:none，当你需要它时使用 jquery 再次查看它
【讨论】：
【参考方案2】：你有这两行：
<input type="text" name="amount" value="1" size="1" /><br />
<input type="text" name="timelimit" value="0" size="1" />
把它们删掉并用以下内容替换它们：
<input type="hidden" name="amount" value="1" size="1" /><br />
<input type="hidden" name="timelimit" value="0" size="1" />
现在对于您要隐藏的最后一个元素，您只需指定：
最后一个是纯文本或html文本单选按钮。
基于此，我真的不知道你想隐藏哪个。我假设你在谈论这些：
<input type="radio" name="contenttype" value="" />
<input type="radio" name="contenttype" value="html" checked />
必须替换为：
<input type="hidden" name="contenttype" value="" />
<input type="hidden" name="contenttype" value="html" checked />
