标题: AJAX支持的自动填充表单
jsf的一个Ajax扩展项目, 其实对于使用myfaces的用户来说还有个更的选择:使用MyFaces Sandbox 中的 InputSuggestAjax 用法如下:
1.创建一个managed bean:

package test;

import java.util.ArrayList;

import java.util.List;

public class Bean {

         //In that function all what you had to do is to

         //Specify what will be displayed in the list

         //Note that the keyword is the text entered by the user

         public List getSuggestedWords(String keyword) {

                     List list = new ArrayList();

                     list.add(keyword + " Ahmed Saleh");

                     list.add(keyword + " Kahki");

                     list.add(keyword + " Kourany");

                     list.add(keyword + " Kiki");

                     list.add(keyword + " Saleh Abouetta");

                     list.add(keyword + " Hashim");

                     return list;

         }

         public String getCurrentValue() {

                     return currentValue;

         }
         public void setCurrentValue(String currentValue) {

                     this.currentValue = currentValue;

         }
         String currentValue;

}

2.    jsp 页面代码

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>

<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<%@ taglib uri="http://myfaces.apache.org/sandbox" prefix="s" %>

<html>

<head>

<title>Ajax JSF sample (InputSuggestAjax)</title>

</head>

<body>

<f:view>

<h:form>

  <h:outputText value="Enter your name : "/>

<s:inputSuggestAjax suggestedItemsMethod="#{bean.getSuggestedWords}"

value="#{bean.currentValue}" />

<br />

<h:commandButton action="" value="Submit"/>

<br />

<h:outputText value="Your name is #{bean.currentValue}"/>

</h:form>

</f:view>

</body>

</html>

3.  web.xml配置

<context-param>

  <param-name>javax.faces.STATE_SAVING_METHOD</param-name>

  <param-value>client</param-value>

</context-param>

//Instead of server make the state saving method on the client to make it works
