在jsp页面中使用jstl循环取参数，非数字字符报错XXXX is not defined

在数值为非数字类型的引用上添加单引号

错误：

<c:forEach items="${dayList}" var= "day">
    info = {title: ${day.week}, width: 80};  //报错：提示day.week is not defined
    colsList2.push(info);
</c:forEach>

正确：

<c:forEach items="${dayList}" var= "day">
    info = {title: '${day.week}', width: 80};  
    colsList2.push(info);
</c:forEach>
