表单标签

Struts2表单标签对应着HTML中的表单元素，Struts2表单标签提供了很多简单易用的属性，会大大简化开发的过程。在开发时，这些表单属性实际上对应着Action中的属性值，Struts2框架会将提交的表单信息直接赋给对应的Action属性。

1. form标签

<s:form>标签用来产生HTML对应的<form>标签。属性：

• action: 可选，指定提交时对应的action
• namespace:

2. submit标签

<s:submit>主要用于产生HTML中提交按钮。属性：

• action: 可选，指定提交时对应的action
• method: 可选，指定action调用方法

3. checkbox标签

<s:checkbox>标签用于创建复选框。属性：

• name: 可选
• value: 可选
• label: 可选，生成一个label元素
• fieldValue: 可选，指定真实的value值，会屏蔽value属性值

代码：

<s:checkbox value="true" name="tongyi"></s:checkbox>

4. checkboxlist标签

下面分别以三种方式展现checkboxlist标签：自定义List、自定义Map、Action中的属性。属性：

• name: 可选
• list: 必须，可以是Collection/Map/Enumeration/Iterator/array等。如果list的属性为Map，则Map的key成为选项的value；Map的value成为选项的内容
• listKey: 可选，指定集合对象中的哪个属性作为选项的value
• listValue: 可选，指定集合对象中的哪个属性作为选项的内容

代码：

        <s:checkboxlist name="aihao1" value="'旅游1'" list="{'爱好1','旅游1','美女1'}"></s:checkboxlist>
        <br/>
        <s:checkboxlist name="aihao2" value="{'1','2'}"    list="#{'1':'爱好1','2':'旅游1','3':'美女1'}"></s:checkboxlist>
        <br/>
        <s:checkboxlist value="checkedValue" name="aihao3" list="aihaoList" key="" listKey="id" listValue="aihao"></s:checkboxlist>

效果：

5. combobox标签

下面分别以二种方式展现combobox标签：自定义Map、Action中的属性。属性：

• name: 可选
• list: 必须，指定集合，该集合中的元素对应生成的列表项
• headerKey: 可选，headerValue的键，默认是“-1”
• headerValue: 可选，用作标题的选项的文本，因为它是一个标题，所以是只读的，不能选择
• label: 可选，生成一个label元素

代码：

        <s:combobox name="combobox1" list="#{1:'java',2:'delphi',3:'c#'}"></s:combobox>
        <br/>
        <br/>
        <s:combobox name="combobox2" list="aihaoList" listKey="id" listValue="aihao"></s:combobox>

效果：

6. doubleselect标签

<s:doubleselect>标签创建两个相关联的列表框，即第二个列表框会根据第一个列表框的选择而变化。属性：

• list: 必须，可以是Collectin/Map/Enumeration/Iterator/array等，指定要迭代的集合。如果list的属性为Map，则Map的key成为选项的value； Map的value成为选项的内容
• listKey: 可选，指定集合对象中的哪个属性作为选项的value，该选项只对第一个列表框起作用
• listValue: 可选，指定集合对象中的哪个属性作为选项的内容，该选项只对第一个列表框起作用
• doublelist: 必须，指定第二个列表框要迭代的集合
• doubleListKey: 可选，指定集合对象中的哪个属性作为选项的value，该选项只对第二个列表框起作用
• doubleListValue: 可选，指定集合对象中的哪个属性作为选项的内容，该选项只对第二个列表框起作用
• doubleName: 必须，指定第二个列表框的name属性
• multiple: 可选，是否多选，默认为false

6.1 访问自定义变量的值

        <s:set var="shengShiDoubleList"
            value="#{'吉林省':{'吉林市','长春市'},
                     '黑龙江省':{'大庆市','哈尔滨市'},
                     '辽宁省':{'沈阳市','大连市','盘锦市'}
                     }"></s:set>
        <s:doubleselect doubleList="#shengShiDoubleList[top]"
            list="#shengShiDoubleList.keySet()" doubleName="shiSimple"
            name="shengSimple"></s:doubleselect>

6.2 访问Action实例中的属性，String方式

        <s:doubleselect doubleList="shengShiMapString[top]"
            list="shengShiMapString.keySet()" doubleName="shiMapString"
            name="shengMapString"></s:doubleselect>

6.3 访问Action实例中的属性，Bean方式，设置默认值

        <s:doubleselect doubleList="shengShiMapBean[top]"
            list="shengShiMapBean.keySet()" doubleName="shiMapBean"
            name="shengMapBean" doubleListKey="shiID" doubleListValue="shi"
            listKey="shengID" listValue="sheng"
            value="shengShiMapBean_ShengDefault"
            doubleValue="shengShiMapBean_ShiDefault"></s:doubleselect>

效果之一：

7. head标签

<s:head>标签主要用于生成HTML的HEAD部分。暂时忽略，因为它有负面影响。

8. file标签

<s:file>标签用于创建一个文件选择框，生成HTML的<input type="file"/>标签。属性：

• accept: 可选，指定接受文件MIME类型，默认为input

9. hidden/textfield/password/textarea标签

放一块介绍：hidden具有name/value属性；password具有name/size/maxLength等属性；其它略。

        <s:hidden name="hiddenValue1" value="%{listStringLeftDefault}" />
        <s:textfield name="username" value="%{listStringLeftDefault}"></s:textfield>
        <br/>
        <s:password name="password"></s:password>
        <br/>
        <s:textarea name="textarea1" cols="30" rows="5"    value="%{listStringLeftDefault}"> </s:textarea>

10. inputtransferselect标签

<s:inputtransferselect>标签主要用为获取输入转到列表框中，或从列表中移除。属性：

         removeLabel="remove"
         addLabel="移右边去吧"/>

效果：

11. label标签

<s:label>标签用于生成HTML中的<label>标签。XHTML主题下的<s:label>标签可以输出两个HTML的<label>标签，位于一行的两列上，左列的<label>标签提示作用，而右列的<label>则用于显示Action属性数据。SIMPLE主题下的<label>标签只输出一个HTML label标签。

<s:label name="address" value="address 100"/>

12. optiontransferselect标签

<s:optiontransferselect>标签用于创建一个选项转移列表组件。它由两个<select>标签以及它们之间的用于将选项在两个按钮之间相互移动的按钮组成。属性：

12.1 访问自定义变量的值

        <s:set var="initialList" value="{'北京市','沈阳市','天津市'}"></s:set>
        <s:optiontransferselect doubleList="" list="#initialList"
            doubleName="constRightValue" name="constLeftValue"

                listKey="key" listValue="value"></s:optgroup>
        </s:select>
        <br/>
        <br/>
        <s:select list="listStringLeft" name="select4" size="10" multiple="true"></s:select>
        <br/>
        <br/>
        <s:select list="aihaoList" name="select5" listKey="id" listValue="aihao"></s:select>
        <br/>
        <br/>
        <s:select list="{'英国','法国'}" name="select6">
            <s:optgroup list="aihaoList" label="扩展城市" listKey="id"
                listValue="aihao"></s:optgroup>
        </s:select>

效果：

14. optgroup标签

<s:optgroup>标签用于生成一个下拉列表框的选项组，通常情况下，该标签放在<s:select>标签中使用。一个下拉列表框可以包含多个选项组。属性：

• list: 必须，这些属性含义参考之前标签介绍即可，都一样的
• listKey:
• listValue:

代码：

        <s:select label="My Selection"
               name="mySelection"
               value="%{'POPEYE'}"
               list="%{#{'SUPERMAN':'Superman', 'SPIDERMAN':'spiderman'}}">
              <s:optgroup label="Adult"
                    list="%{#{'SOUTH_PARK':'South Park'}}" />
              <s:optgroup label="Japanese"
                    list="%{#{'POKEMON':'pokemon','DIGIMON':'digimon','SAILORMOON':'Sailormoon'}}" />
        </s:select>    

效果：

15. radio标签

下面分别以三种方式展现radio标签：自定义List、自定义Map、Action中的属性。属性：

• list: 必须，这些属性含义参考之前标签介绍即可，都一样的
• listKey:
• listValue:

代码：

        <s:radio list="{'struts','spring','hibernate'}" value="'spring'" name="radio1"></s:radio>
        <br/>
        <s:radio list="#{'zhangsan':'struts','lisi':'spring','wangwu':'hibernate'}" value="'wangwu'" name="radio2"
            listKey="key" listValue="value"></s:radio>
        <br/>
        <s:radio list="aihaoList" name="radio3" listKey="id" listValue="aihao"></s:radio>

效果：

16. reset标签

<s:reset>标签用来创建一个重置按钮。

<s:reset name="reset" value="重置"/>

17. token标签

<s:token>标签用于防止表单重复提交，实际上该标签在转化成HTML元素时，添加了一个隐藏域，该隐藏域存储当前提交的值，由于每次提交的值都不一样，如果拦截器在拦截信息时检测到两次提交表单的该隐藏域值相等，则阻止表单提交。

代码：

<s:form>
    <s:tonek/>
</s:form>

上面的代码在转换为HTML后会变成如下的代码：

    <input type="hidden" name="struts.token.name" value="token" />
    <input type="hidden" name="token" value="OKM7WWELJ0EFERWQK7JBRTV1BUC8EV8Z" />

由上面的代码可以看到，生成的HTML中含有一个隐藏域，实际上，其value属性值提交后放入session中，当再提交后会检查是否重复提交。

18. updownselect标签

<s:updownselect>标签用来创建一个带有上下移动的按钮的列表框，可以通过按钮来调整列表框的选项的位置。属性：

• list: 必须，这些属性含义参考之前标签介绍即可，都一样的
• listKey:
• listValue:
• multiple:
• moveUpLabel:
• moveDownLabel:
• allowMoveUp: 默认true
• allowMoveDown: 默认true
• allowSelectAll: 默认true
• selectAllLabel: 设置分部选择按钮上的文本

代码：

        <s:updownselect list="{'java','c','python'}" name="udselect1"></s:updownselect>
        <br/>
        <br/>
        <s:updownselect list="aihaoList" name="udselect2" moveDownLabel="向下移"
            moveUpLabel="向上移" selectAllLabel="全选" listKey="id" listValue="aihao"></s:updownselect>

效果：
