关于下拉框,不显示内容
前端代码为
```javascript
<tr>
<td class="one">类别</td>
<td>
<select name="typeId">
<c:forEach items="${typetlist}" var="type">
<option value="${type.typeId}">${type.typeName}</option>
</c:forEach>
</select>
</td>
</tr>
typeList已经在监听器中赋予到公共作用域
@Override
public void contextInitialized(ServletContextEvent servletContextEvent) {
//手工从spring容器取出ProductTypeServiceImpl对象
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext_*.xml");
ProductTypeService productTypeService = (ProductTypeService) context.getBean("ProductTypeServiceImpl");
List<ProductType> typeList = productTypeService.getAll();
//放入全局应用作用域中,新增页面,修改页面,前台查询功能提供全部商品类别集合
servletContextEvent.getServletContext().setAttribute("typeList",typeList);
}
```
