组合中的语言选择 [英] Language selection in the combo

问题描述

我将servlet配置为支持国际化，如下所示:

I configured my servlet to support internationalization, just as I showed below:

<bean id="messageSource"
    class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="classpath:messages" />
    <property name="defaultEncoding" value="UTF-8"/>
</bean>

<bean id="localeChangeInterceptor"
    class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
    <property name="paramName" value="lang" />
</bean>

<bean id="localeResolver"
    class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
    <property name="defaultLocale" value="en"/>
</bean>

<bean id="handlerMapping"
    class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
    <property name="interceptors">
        <ref bean="localeChangeInterceptor" />
    </property>
</bean>

在JSP页面上，我以这种方式添加了语言选择:

On the JSP page, I added the choice of language in such a way:

<%@taglib uri="http://www.springframework.org/tags" prefix="spring"%>


<h3><spring:message code="label.title"/></h3>

<span style="float: right">
    <a href="?lang=en">en</a>
    |
    <a href="?lang=de">de</a>
</span>

如何替换select(组合)的上述代码部分?

How do I replace the above code component of a select (combo)?

(伪代码)

<td><form:select path="language" onchange="">
            <form:option value="0" label="..." />
            <form:options items="${languageList}" />
        </form:select></td>

请帮助

编辑 我不想将任何内容设置为默认值.他想被选中此选项，他选择了您.您将看到一个示例:

EDIT I do not want anything to set as the default. He wants to be chosen this option, he chose you. You will see an example:

第一步 本地主机:8080/newUser -> 在控制器中

The first step localhost: 8080/newUser -> In controller

@ RequestMapping (value = "/ newuser" method = RequestMethod.GET)
public ModelAndView showNewUser (ModelMap model) {
ModelAndView mav = new ModelAndView ();
mav.mav.setViewName ("newuser");
User user = new User ();
mav.getModel (). put ("user", user);
return mav;

我的JSP表格 ...

My JSP forms ...

<form id="langForm" action="newUse" method="get">
<table>
<tr>
<td> <a href="#"> <spring:message code="label.helpLink" /> </ a> </ td>
<td> <select name="lang" id="lang">
<option value="de"> <spring:message code="languageName.de"> </ spring: message> </ option>
<option value="en"> <spring:message code="languageName.en"> </ spring: message> </ option>
</ select> </ td>
</ tr>
</ table>
</ form>

...

<script type="text/javascript">
$ ("# lang"). change (function () {
document.forms ["langForm"] submit ();
});
</ script>

第二步 -最终用户从组合选项"languageName.en"中选择.然后重新加载页面 (localhost:8080/newUser?lang = zh)将语言更改为EN，但是该组合仍然被选为第一项.我想选择的是您在第2步中选择的那个.因此，我将保存状态.

The second step - End-user selects from the combo options "languageName.en. Followed by reloading the page (localhost: 8080/newUser? lang = en) to change the language to EN but the combo is still selected as the first item. I would like to chose was the one you selected in step 2 So, I would save the state.

添加

<form>
        <select name="lang" id="lang" onchange="this.form.submit();">
            <option value="pl"><spring:message code="languageName.pl"></spring:message></option>
            <option value="en"><spring:message code="languageName.en"></spring:message></option>
        </select>
        </form>

如何在没有模型的情况下保留该选项?

How to keep the option without a model?

推荐答案

在jsp中

<form:select path="language" onchange="">
<c:forEach var="lan" item="${languageList}">
   <form:option value="0" label="${lan}" />
   <form:options items="${lan}" />
<c:forEach />
</form:select>

添加将监听其状态变化的javascript.如果发生更改，请在会话中反映此参数语言

add javascript that will listen to its change in state. if change occurs reflect this param language in session

更新:

假设您有这样的组合框

<select>
  <option>Small</option>
  <option>Medium</option>
  <option>Large</option>
  <option>X-Large</option>
</select>

，并且您希望默认选择X-large，将HTML设置为这样

and you want X-large to be selected by default, make HTML like this

<select>
  <option>Small</option>
  <option>Medium</option>
  <option>Large</option>
  <option selected="true">X-Large</option>
</select>

做到

<select name="lang" id="lang">
<option value="de" <c:if ${sessionBean.lan}=='de'>seelcted='true'</c:if>> <spring:message code="languageName.de"> </ spring: message> </ option>
<option value="en"  <c:if ${sessionBean.lan}=='en'>seelcted='true'</c:if>> <spring:message code="languageName.en"> </ spring: message> </ option>
</ select>
