## a4j:ajaxListener ##

## 和 ActionListener或者ValueChangeListener的工作方式一样, 只是仅用于AJAX容器. 添加一个指定的类作为AjaxEvent的监听器. (sent in case of an AJAX request for this container).  Table 4.1. a4j:ajaxListener attributes  <table style="word-wrap:break-word">       <tbody style="word-wrap:break-word">    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">type</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">注册到AjaxListener 中类的完全限定的Java类名</td>    </tr>   </tbody>  </table>       …  当来自于Region的AJAX request触发时,将调用bean的'processAjax'方法. ##

## a4j:region ##

## 该标签定义在AJax请求处理过程中被发送到服务器端解码的部分JSF组件树.  Table 4.2. a4j:region 的属性  <table style="word-wrap:break-word">       <tbody style="word-wrap:break-word">    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">selfRendered</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">如果为true,在调用应用程序(InvokeApplication )阶段自渲染子树(如果immediate 属性设置为true则是 Decode)</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">renderRegionOnly</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">标记,用来决定活动区域外的内容在Ajax响应中是否渲染.如果为"true" , 在AJAX response过程中活动区域外的组件都不渲染. 如果为"false", 将渲染包含在响应中的所有组件树.默认值为"true"</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">rendered</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">如果为 false, 该组件将不被重新渲染.</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">id</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">每个组件都应该有个唯一的id. 如果没有指定的话,将会自动产生.</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">immediate</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">如果该组件被Ajax请求激活的话,标记该组件应该立即(在应用请求值阶段)被感兴趣的监听器和动作处理,而不是等到调用应用程序阶段.(译者注:该标记和JSF中的immediate标记所代表的意思差不多,跳过验证阶段到呈现响应阶段)</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">binding</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">组件绑定</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">ajaxListener</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">方法绑定,当该组件被ajax请求激活时,将调用该监听器方法处理该事件.该方法必须为public的并且接受一个 AjaxEvent 参数,返回void.</td>    </tr>   </tbody>  </table>       如果在该组件的区域中有一个Ajax请求调用了 – 该区域将根据Ajax的设置被框架处理. ##

## a4j:page ##

## 该组件呈现一个完全的HTML页面结构.它必须是view root (JSP tag)的第一个(并且是仅有的一个)子组件. 没有Html代码可以在该组件的外面. 它也支持在Ajax请求中处理子组件,就和一样.对于一个普通的请求,它将把结果呈现为在客户端页面元素中的 ##

## a4j:support ##

## 在 UIComponent-based组件上添加ajax功能,使他们有JavaScript事件属性. 在解码期间:如果一个请求为Ajax-performed, 从ExternalContext 中的requestParameterMap属性中得到Map,如果该Map中"clientId" key对应的值非空,在组件上创建一个 javax.faces.event.ActionEvent, 并且传递该事件到该组件的queueEvent()中,然后把他的reReander区域中的组件id添加到reReander属性中.在编码过程中.不编码一个组件. 相反的,在父组件上添加一个与事件属性的值相同的值绑定(Instead, it adds ValueBinding for a property of the parent component with the name as a value of its "event" property).结果,当呈现时,父组件创建一个在提交一个ajax请求时用到的JS代码.如果该组件有子UIParameter组件,添加他的name/value作为附加的请求参数.如果父组件是一个UIInput的实例,并且ajaxType属性是input, 则也提交input 域中的值. 在这种情况下,你可以在UIForm外面提交一个单一的input域. (As a result, when rendered, the parent component builds JavaScript code for submitting an AJAX request on this event. If the component has child UIParameter components, appends it's name/value as additional request parameters. If a parent component is an instance of UIInput and the ajaxType property is "input", submits the value of the input field, also. In this case, you can submit a single input field outside of UIForm.)  Table 4.4. a4j:support 属性  <table style="word-wrap:break-word">       <tbody style="word-wrap:break-word">    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">actionListener</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">方法绑定,当该组件被ajax请求激活时,将调用该监听器方法处理该事件.该方法必须为public的并且接受一个 AjaxEvent 参数,返回void.</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">parentProperties</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">parentProperties</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">action</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">方法绑定到要被激活的程序动作方法, 如果该 UIComponent 被用户激活, 根据immediate属性的值,方法在 请求处理生命周期中的Apply Request Values 或者 Invoke Application 阶段 被调用.</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">oncomplete</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">在客户端请求完成时调用的js代码</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">rendered</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">如果为false,该组件将不会被显示.</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">status</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">Request status 组件的id(在 UIComopnent.findComponent()中使用)</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">reRender</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">该组件调用Ajax请求后重新渲染的组件的ID(在 UIComopnent.findComponent()中使用),可以使一个id,也可以使逗号分开的很多id,或者是数据or集合的EL表达式</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">targetId</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">reRender的别名 : 该组件调用Ajax请求后重新渲染的组件的ID(在 UIComopnent.findComponent()中使用),可以使一个id,也可以使逗号分开的很多id,或者是数据or集合的EL表达式</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">id</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">每个组件都应该有个唯一的id. 如果没有指定的话,将会自动产生.</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">disableDefault</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">使目标事件的动作不可用 ( 在javascript代码中添加 "return false;" )</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">requestDelay</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">在JS事件上延迟 ( 单位 ms. )发送Ajax请求.与事件队列公共工作可以减少键盘或者鼠标移动触发请求的次数</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">eventsQueue</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">用来避免在同一个事件上的重复请求的队列的名字.可以用来减少周期事件(如:按键,鼠标移动)请求的次数.</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">bypassUpdates</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">如果使true,在处理验证阶段后跳过更新模型值阶段到呈现阶段.可以用来验证组件的输入值.</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">immediate</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">如果该组件被Ajax请求激活的话,标记该组件应该立即(在应用请求值阶段)被感兴趣的监听器和动作处理,而不是等到调用应用程序阶段.(译者注:该标记和JSF中的immediate标记所代表的意思差不多,跳过验证阶段到呈现响应阶段)</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">limitToList</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">如果为true,仅仅更新'reRender'属性中指定的组件,否则(默认值)更新所有Ajax Region中的组件</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">ajaxSingle</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">如果为 true , 仅仅提交一个field/link,而不是整个form中的内容.</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">event</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">父组件的JS事件属性的名称 ( onclick , onchange, etc. ) , for which we will build AJAX submission code.</td>    </tr>    <tr style="word-wrap:break-word">     <td style="word-wrap:break-word; margin:0px; padding:0px">binding</td>     <td style="word-wrap:break-word; margin:0px; padding:0px">组件绑定.</td>    </tr>   </tbody>  </table>       所有你需要指定的东西 - 父组件用来触发ajax请求的事件和被reRender的区域, 和处理事件的Java bean方法.  … <a4j:support event="change" reRender="\#\{partsId.list\}" action="\#\{Some.show\_hide\}"/>  …  因此,在上面的例子中,checkbox状态的改变将提交当前的区域. 'show\_hide'动作将被调用,并且 'list'中的id所指定的组件将被更新. ##

## a4j:commandLink ##

## 呈现一个Html 元素,当点击时的动作就象一个form提交一样.  在解码的过程中:  从ExternalContext的属性requestParameterMap中得到一个Map,如果该Map中包含"clientId" key的非空值, 在组件上创建一个 javax.faces.event.ActionEvent 事件,并且传递该事件给组件的queueEvent() 方法.如果该请求是Ajax-performed,把reRander属性中的IDs值添加到嵌套的AjaxContainer的 rendered areas list中 ,在解码的过程中也添加组件的参数(PARAM\_NAME 和 PARAM\_VALUE 是任何嵌套的子UIParameter的names 和 values .) names 和 values必须是被URLEncoded处理过的.如果styleClass属性被指定了,呈现它的值为html中的class属性的值. 呈现任何non-UIParameter子组件为的相应的子组件. 这些看起来就像一个Link文本.

During Encoding: Creates two "span" elements with id created as clientId of this component or of target AJAX region (pointed to by the "for" property) with appended ":status.start" and ":status:stop" strings. "start" span has "display:none" style (hidden). Inside this span, renders the value of the startText/stopText properties or, if they exist, the content of "start" and "stop" facets. On performing an AJAX request, the client-side script changes the visibility of the "start" span and hides "stop". After all requests for this indicator are completed, restores "stop" and hide "start" start\[style,styleClass\] and stop\[style,styleClass\] are rendered for spans as style and class atributes, respectivetly.  在解码的过程中:  ....
