利用jquery动态获取不同语言页面

1:制作选择连接

<divid="language">

<a id="zh_TW" href="">繁</a> |

<aid="zh_CN" href="">简</a> |

<aid="en" href="">EN</a>

</div>

2：编写jquery来处理超链接click事件

var $atag = $("a");

$atag.click(function(){

varurl = "Language.action";

vardata = {

sourcePage:"/page/i18n.jsp",

setLanguage:this.id

};

$.get(url,data);

});

3:编辑action类

publicclass I18nAction extends ActionSupport{

String setLanguage = null;

String sourcePage = null;

public String getSetLanguage(){

return setLanguage;

}

public void setSetLanguage(String setLanguage) {

this.setLanguage =setLanguage;

}

public String getSourcePage() {

return sourcePage;

}

public void setSourcePage(String sourcePage) {

this.sourcePage =sourcePage;

}

public String changeLanguae(){

System.out.println("setLanguage=" + setLanguage +"sourcePage=" +sourcePage);

ActionContext ctx = ActionContext.getContext();

//设置语言

setLanguage = setLanguage.trim();

if("en".equals(setLanguage)){

ctx.getSession().put("WW_TRANS_I18N_LOCALE", Locale.ENGLISH);

ctx.setLocale(Locale.ENGLISH);

}else if ("zh_CN".equals(setLanguage)){

ctx.getSession().put("WW_TRANS_I18N_LOCALE", Locale.SIMPLIFIED_CHINESE);

ctx.setLocale(Locale.SIMPLIFIED_CHINESE);

}else if("zh_TW".equals(setLanguage)){

ctx.getSession().put("WW_TRANS_I18N_LOCALE", Locale.TRADITIONAL_CHINESE);

ctx.setLocale(Locale.TRADITIONAL_CHINESE);

}else{

ctx.getSession().put("WW_TRANS_I18N_LOCALE", Locale.FRANCE);

ctx.setLocale(Locale.FRANCE);

}

if(sourcePage!=null){

return"success";

}else{

return"error";

}

4：编辑struts.xml文件

<actionname="Language" class="i18n.I18nAction"method="changeLanguae">

<resultname="success">${sourcePage}</result>

<resultname="error">/index.jsp</result> </action>
