Javascript -在JSP中定义变量

Question

我有一个基于Spring Web模型-视图-控制器(MVC)框架的项目。Spring Web model-view-controller (MVC)框架的版本是部署在WebLogic服务器上的3.2.8版本: 12.1.2.0.0我的JSP中有以下代码

<script src="${contextPath}/scripts/jquery.min.js"  type="text/javascript">

var optionsEUCountriesArray = [];
var optionsNonEUCountriesArray = [];

<c:forEach items="${countries}" var="country" varStatus="status">
    var option${country.id} = new Option("${country.id}","${country.description}");
    <c:choose>
    <c:when test="${country.euMember}">
        optionsArray.push(option${country.id});  
    </c:when>
    <c:when test="${not country.euMember}">
        optionsArray.push(option${country.id});
    </c:when>       
    </c:choose>
</c:forEach>
</script>

<script src="${contextPath}/scripts/selectbox.js"   type="text/javascript"></script>

在selectbox.js中，我使用了变量optionsEUCountriesArray，但得到以下错误

Uncaught ReferenceError: optionsEUCountriesArray is not defined

您正在组合脚本。也许这应该可以解决你的问题..

 <script src="${contextPath}/scripts/jquery.min.js"  type="text/javascript"> </script>
<script>

var optionsEUCountriesArray = [];
var optionsNonEUCountriesArray = [];
<c:forEach items="${countries}" var="country" varStatus="status">
    var option${country.id} = new Option("${country.id}","${country.description}");
    <c:choose>
    <c:when test="${country.euMember}">
        optionsArray.push(option${country.id});  
    </c:when>
    <c:when test="${not country.euMember}">
        optionsArray.push(option${country.id});
    </c:when>       
    </c:choose>
</c:forEach>
</script>
