如何使用Spring和Dojo进行下拉列表（表单：select）？我正在使用Dojo开发一个Spring项目，以使我的页面看起来很漂亮。我有输入字段，但现在我的一个页面上有一个下拉列表。如何将下拉菜单作为我的dojo输入，以及如何使其成为必需项。请看下面的代码......
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"%>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>

<link type="text/css" rel="stylesheet"
href="<c:url value="/resources/dijit/themes/claro/claro.css" />" />
<script type="dojo/method" data-dojo-event="onSubmit">
if(this.validate()){
return confirm('Form is valid, press OK to submit');
}else{
alert('Form contains invalid data. Please correct first');
return false;
}
return true;

看起来像复制/粘贴错误。首先，您的表单中没有任何ID：选择
<form:select path="sex">
另一件事是你的表单中有错误的id：select的装饰器。您从表单中复制了它：输入id =“name”。
Spring.addDecoration(new Spring.ElementDecoration({
**elementId : "name",**
widgetType : "dijit.form.ValidationTextBox",
widgetAttrs : {
promptMessage : "Enter Name",
required : true
}
}));
