!-- 需要在struts-config.xml中action的path為"/tag"的name屬性中指定一個form bean -->
html:form action="/tag">
html:hidden property="id" />
userName:html:text property="userName" />
password:html:password property="password" />br>
!--
在checkbox后面添加一個和checkbox的屬性同名并且value為“false”的隱藏輸入框，強迫Struts去重新設置checkbox的屬性值
一般情況下，在ActionForm中都使用布爾型變量來表示一個checkbox，這是因為它要么沒被選中，要么就是被選中。

multibox標簽生成網(wǎng)頁上的復選框，其實它的功能和checkbox一樣。
所不同的是，在此復選框所在的ActionForm中使用一個數(shù)組來表示該復選框。
所以，一般情況下，推薦使用multibox。
private boolean checkbox1;
private String[] hobbies;
-->
checkbox1:html:checkbox property="checkbox1" />
input type="hidden" name="checkbox1" value="false">
checkbox2:html:checkbox property="checkbox2" />
input type="hidden" name="checkbox2" value="false">br>

hobbies:swimhtml:multibox property="hobbies" value="1" />
readinghtml:multibox property="hobbies" value="2" />
walkinghtml:multibox property="hobbies" value="3" />br>

!-- 從form傳來的radio若已經(jīng)setter賦值了，則在頁面上value值與之相等的就會被勾選 -->
gender:malehtml:radio property="sex" value="1" />
femalehtml:radio property="sex" value="2" />br>

!-- provinces在form bean中定義及賦值如下:
private Collection provinces;

provinces = new ArrayList();
provinces.add(new OptionBean("beijing", "100000"));
provinces.add(new OptionBean("hebei", "110000"));
provinces.add(new OptionBean("tianjin", "120000"));
-->
html:select property="from">
html:optionsCollection property="provinces"/>
/html:select>

!--
size為1，則只同時顯示一個選項。
還有一個multiple屬性，當其為true時，該選擇列表就允許多選。用戶可以通過鼠標的拖動，或是按住Ctrl鍵進行多選。
當multiple屬性為true時，在ActionForm中對應的屬性應是一個數(shù)組類型以便同時向其賦上用戶選中的多個值。
-->
html:select property="from" size="3" multiple="true">
html:option value="value1">Show Value1/html:option>
html:option value="value2">Show Value2/html:option>
html:option value="value3">Show Value3/html:option>
/html:select>br>

html:textarea rows="5" cols="30" property="introduction">/html:textarea>br>
