控件标签

Struts 2 的标签有一组标签，更容易控制流程页面执行。以下是重要的Struts2控制标签列表：

if /else 标签:

这些标签执行可在每一种语言找到的一种基本条件流程。 'If'标签可用于本身或与“Else If''标签和/或单/多'Else'标签，如下图所示：

<span class="tag" style="margin: 0px; padding: 0px;"><s:if</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="atn" style="margin: 0px; padding: 0px;">test</span><span class="pun" style="margin: 0px; padding: 0px;">=</span><span class="atv" style="margin: 0px; padding: 0px;">"%{false}"</span><span class="tag" style="margin: 0px; padding: 0px;">></span><span class="pln" style="margin: 0px; padding: 0px;">    </span><span class="tag" style="margin: 0px; padding: 0px;"><div></span><span class="pln" style="margin: 0px; padding: 0px;">Will Not Be Executed</span><span class="tag" style="margin: 0px; padding: 0px;"></div></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"></s:if></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"><s:elseif</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="atn" style="margin: 0px; padding: 0px;">test</span><span class="pun" style="margin: 0px; padding: 0px;">=</span><span class="atv" style="margin: 0px; padding: 0px;">"%{true}"</span><span class="tag" style="margin: 0px; padding: 0px;">></span><span class="pln" style="margin: 0px; padding: 0px;">    </span><span class="tag" style="margin: 0px; padding: 0px;"><div></span><span class="pln" style="margin: 0px; padding: 0px;">Will Be Executed</span><span class="tag" style="margin: 0px; padding: 0px;"></div></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"></s:elseif></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"><s:else></span><span class="pln" style="margin: 0px; padding: 0px;">    </span><span class="tag" style="margin: 0px; padding: 0px;"><div></span><span class="pln" style="margin: 0px; padding: 0px;">Will Not Be Executed</span><span class="tag" style="margin: 0px; padding: 0px;"></div></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"></s:else></span>

iterator标签：

这些迭代器将遍历一个值。一个可迭代的值可以是任何的java.util.Collection 和 java.util.Iterator。虽然超过一个迭代器遍历排序，可以使用标签对结果进行排序或子集标签的列表或者数组得到一个子集。

下面的示例检索当前对象的值栈getDays()方法的值，并用它来遍历。<s:property/>标签打印出迭代器的当前值。

<span class="tag" style="margin: 0px; padding: 0px;"><s:iterator</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="atn" style="margin: 0px; padding: 0px;">value</span><span class="pun" style="margin: 0px; padding: 0px;">=</span><span class="atv" style="margin: 0px; padding: 0px;">"days"</span><span class="tag" style="margin: 0px; padding: 0px;">></span><span class="pln" style="margin: 0px; padding: 0px;">  </span><span class="tag" style="margin: 0px; padding: 0px;"><p></span><span class="pln" style="margin: 0px; padding: 0px;">day is: </span><span class="tag" style="margin: 0px; padding: 0px;"><s:property/></p></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"></s:iterator></span>

merge标签：

这些合并标记需要两个或两个以上的列表作为参数，并把它们合并在一起，如下所示：

<span class="tag" style="margin: 0px; padding: 0px;"><s:merge</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="atn" style="margin: 0px; padding: 0px;">var</span><span class="pun" style="margin: 0px; padding: 0px;">=</span><span class="atv" style="margin: 0px; padding: 0px;">"myMergedIterator"</span><span class="tag" style="margin: 0px; padding: 0px;">></span><span class="pln" style="margin: 0px; padding: 0px;">     </span><span class="tag" style="margin: 0px; padding: 0px;"><s:param</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="atn" style="margin: 0px; padding: 0px;">value</span><span class="pun" style="margin: 0px; padding: 0px;">=</span><span class="atv" style="margin: 0px; padding: 0px;">"%{myList1}"</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="tag" style="margin: 0px; padding: 0px;">/></span><span class="pln" style="margin: 0px; padding: 0px;">     </span><span class="tag" style="margin: 0px; padding: 0px;"><s:param</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="atn" style="margin: 0px; padding: 0px;">value</span><span class="pun" style="margin: 0px; padding: 0px;">=</span><span class="atv" style="margin: 0px; padding: 0px;">"%{myList2}"</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="tag" style="margin: 0px; padding: 0px;">/></span><span class="pln" style="margin: 0px; padding: 0px;">     </span><span class="tag" style="margin: 0px; padding: 0px;"><s:param</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="atn" style="margin: 0px; padding: 0px;">value</span><span class="pun" style="margin: 0px; padding: 0px;">=</span><span class="atv" style="margin: 0px; padding: 0px;">"%{myList3}"</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="tag" style="margin: 0px; padding: 0px;">/></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"></s:merge></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"><s:iterator</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="atn" style="margin: 0px; padding: 0px;">value</span><span class="pun" style="margin: 0px; padding: 0px;">=</span><span class="atv" style="margin: 0px; padding: 0px;">"%{#myMergedIterator}"</span><span class="tag" style="margin: 0px; padding: 0px;">></span><span class="pln" style="margin: 0px; padding: 0px;">     </span><span class="tag" style="margin: 0px; padding: 0px;"><s:property</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="tag" style="margin: 0px; padding: 0px;">/></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"></s:iterator></span>

generator 标签:

generator标签生成一个迭代器的基础上提供val属性。以下generator标签生成一个迭代器，并使用迭代器标签打印出来。

<span class="tag" style="margin: 0px; padding: 0px;"><s:generator</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="atn" style="margin: 0px; padding: 0px;">val</span><span class="pun" style="margin: 0px; padding: 0px;">=</span><span class="atv" style="margin: 0px; padding: 0px;">"%{'aaa,bbb,ccc,ddd,eee'}"</span><span class="tag" style="margin: 0px; padding: 0px;">></span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="tag" style="margin: 0px; padding: 0px;"><s:iterator></span><span class="pln" style="margin: 0px; padding: 0px;">     </span><span class="tag" style="margin: 0px; padding: 0px;"><s:property</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="tag" style="margin: 0px; padding: 0px;">/><br/></span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="tag" style="margin: 0px; padding: 0px;"></s:iterator></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"></s:generator></span>

数据标签

Struts 2 的数据标签主要用于操作页面上显示的数据。下面列出的是重要的数据标签：

action标签：

此标记使开发人员能够直接从JSP页面调用动作指定动作的名称和一个可选的命名空间。标签的主体内容是用行动来呈现结果。任何结果处理器定义在struts.xml这个动作将被忽略，指定除非executeResult参数。

<span class="tag" style="margin: 0px; padding: 0px;"><div></span><span class="pln" style="margin: 0px; padding: 0px;">Tag to execute the action</span><span class="tag" style="margin: 0px; padding: 0px;"></div></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"><br</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="tag" style="margin: 0px; padding: 0px;">/></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"><s:action</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="atn" style="margin: 0px; padding: 0px;">name</span><span class="pun" style="margin: 0px; padding: 0px;">=</span><span class="atv" style="margin: 0px; padding: 0px;">"actionTagAction"</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="atn" style="margin: 0px; padding: 0px;">executeResult</span><span class="pun" style="margin: 0px; padding: 0px;">=</span><span class="atv" style="margin: 0px; padding: 0px;">"true"</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="tag" style="margin: 0px; padding: 0px;">/></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"><br</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="tag" style="margin: 0px; padding: 0px;">/></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"><div></span><span class="pln" style="margin: 0px; padding: 0px;">To invokes special method  in action class</span><span class="tag" style="margin: 0px; padding: 0px;"></div></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"><br</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="tag" style="margin: 0px; padding: 0px;">/></span><span class="pln" style="margin: 0px; padding: 0px;"></span><span class="tag" style="margin: 0px; padding: 0px;"><s:action</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="atn" style="margin: 0px; padding: 0px;">name</span><span class="pun" style="margin: 0px; padding: 0px;">=</span><span class="atv" style="margin: 0px; padding: 0px;">"actionTagAction!specialMethod"</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="atn" style="margin: 0px; padding: 0px;">executeResult</span><span class="pun" style="margin: 0px; padding: 0px;">=</span><span class="atv" style="margin: 0px; padding: 0px;">"true"</span><span class="pln" style="margin: 0px; padding: 0px;"> </span><span class="tag" style="margin: 0px; padding: 0px;">/></span>

date标签:

date标签，将让在一个快速和容易的方式格式化日期。可以指定自定义格式（如“DD/ MM / YYYY HH：MM”），可以生成易读的符号（如“2小时，14分钟”），或者可以依傍预定义的格式关键 struts.date.format 属性文件。

Ajax 标签

Struts使用Dojo框架的 AJAX标记实现。首先，这个例子中，你需要添加 struts2-dojo-plugin-2.2.3.jar。你可以得到这个文件的lib文件夹struts2的下载 (C:\struts-2.2.3-all\struts-2.2.3\lib\struts2-dojo-plugin-2.2.3.jar)

对于这个锻炼，让我们修改 helloWorld.jsp如下：

当我们运行上面的例子中，我们可以得到下面的输出：

现在让我们通过这个例子一步来。

首先要注意的是另外一个新的标签库前缀 sx. （struts-dojo-tags）是专门创建的标记库的AJAX集成。

然后在HTML头，我们称之为sx:head。这将初始化Dojo框架，使得它准备为所有的AJAX调用内页。这一步很重要 - ，没有sx:head初始化Ajax调用不会起作用。

首先，我们有自动完成标签。自动完成标签看起来很像一个选择框。它填充了红色，绿色和蓝色的值。但之间的一个选择框而这一次不同的是，它自动完成。也就是说，如果开始键入gr，这将填补它为“green”。除此之外，这个标签是非常相似s:select标签，我们前面介绍。

接下来，我们有一个日期时间选择器。这个标签创建一个输入栏旁边的一个按钮。当按下按钮时，弹出一个显示日期和时间选择器。当用户选择的日期，该日期将填充到输入文本标记属性中所指定的格式。在我们的例子中，我们指定dd/MM/yyyy 日期格式。

接下来我们创建一个URL标记的system.action在前面的练习中，我们创建的文件。它并不一定要的system.action - 它可以是任何行动您之前创建的文件。然后我们有一个div设置超链接的url和延迟设置为2秒钟。会发生什么事而言，"Initial Content"将显示2秒钟，然后div的内容将被替换的内容从hello.action执行。

最后，我们有一个简单的选项卡面板有两个选项卡。标签的div标签“选项卡1和Tab2。

慢慢地随着每一个版本，它应该是值得注意的AJAX标签集成Struts，仍然是一个工作的进步和成熟整合。
