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
