Struts2：复选框 - 隐藏不需要的输入类型
[英]Struts2 s:checkbox - unwanted input type hidden
问题描述
My code: 
我的代码：
<label class="btn btn-default">
<s:checkbox name="viewTypeDescr" /> 
<s:text name="name.contentType" />
</label>
The docs: http://struts.apache.org/release/2.3.x/docs/checkbox.html say that it will render a input[type=checkbox] 文档： http ： //struts.apache.org/release/2.3.x/docs/checkbox.html说它将呈现input[type=checkbox]
Instead here's what I get: 相反，这是我得到的：
<label class="btn btn-default">
<input type="checkbox" name="viewTypeDescr" value="true" id="search_viewTypeDescr">
<input type="hidden" id="__checkbox_search_viewTypeDescr" name="__checkbox_viewTypeDescr" value="true">
Content Type
</label>
That added input[type="hidden"] is making the resulting page invalid because a label can have max 1 input inside. 添加input[type="hidden"]使得结果页面无效，因为标签内部可以有最多1个输入。
Definition of invalid: 无效的定义：
- Go to validator.w3.org 转到validator.w3.org
- Paste the provided HTML code in "Validate by direct input" 将提供的HTML代码粘贴到“通过直接输入验证”
- Decor it with missing
<html><head><title>foo</title></head><body>and</body></html>to lessen the false errors装饰它缺少<html><head><title>foo</title></head><body>和</body></html>以减少错误错误 - Select HTML5 ad doctype 选择HTML5广告文档类型
- Click "Validate" 点击“验证”
- Get this error: "Line xyz, Column abc: The label element may contain at most one input, button, select, textarea, or keygen descendant." 得到此错误：“行xyz，列abc：标签元素最多可包含一个输入，按钮，选择，textarea或keygen后代。”
- Go to spec just in case: "The caption can be associated with a specific form control, known as the label element's labeled control, either using the for attribute, or by putting the form control inside the label element itself." 转到spec以防万一：“标题可以与特定的表单控件相关联，称为标签元素的标记控件，使用for属性，或者将表单控件放在label元素本身中。”
- Discover that "If the for attribute is not specified, but the label element has a labelable element descendant, then the first such descendant in tree order is the label element's labeled control." 发现“如果未指定for属性，但label元素具有可变元素后代，则树序中的第一个这样的后代是标签元素的标记控件。”
- Add that hidden can't be there " http://www.w3.org/html/wg/drafts/html/master/forms.html#category-label " 添加隐藏的不能存在“ http://www.w3.org/html/wg/drafts/html/master/forms.html#category-label ”
Anyway, when you submit your document to QA for validation, they use validator.w3.org and that is all that matters. 无论如何，当您将文档提交给QA进行验证时，他们会使用validator.w3.org，这就是最重要的。
What's the reason of that hidden? 隐藏的原因是什么？ How could I get rid of it or move it elsewhere? 我怎么能摆脱它或移动到其他地方？

I created a new theme, with parent=simple, and will use that. 我用parent = simple创建了一个新主题，并将使用它。
Still don't know what's the supposed purpose of that hidden... 仍然不知道隐藏的假设目的是什么......
