如何让 Struts 单选标签创建单选按钮的垂直列表 [英] How to make Struts radio tag create a vertical list of radio buttons

问题描述

我正在使用一个 struts 单选标签，该标签填充了具有两个字段的对象列表:

类 MyAction {列出<我的对象>我的清单;字符串 selectedId公共字符串执行(){...myList = new ArrayList();myList.add(new MyObject("1","first object");myList.add(new MyObject("2","第二个对象");myList.add(new MyObject("3","第二个对象");...}//myList & 的 Getter 和 Setter选定的Id...}类我的对象 {字符串标识；字符串名称；我的对象(字符串 id，字符串名称){这个.id = id;this.name = 名称；}//id & 的 Getter 和 Setter名称...}

这是我在页面上用来显示单选按钮列表的内容

<s:radio key="selectedId" list="myList" listKey="id" listValue="name"/>

但是，这会生成单选按钮的水平列表.我尝试为它们添加 css 样式:

<style>.垂直输入{显示:块；}</风格>

但这会导致标签和单选按钮也显示在不同的行上，而不是单选按钮和标签显示在同一行:

<块引用>

第一个对象

第二个对象

第三个对象

我想要的是:

<块引用>

第一个对象

第二个对象

第三个对象

解决方案

其实很简单，我的意思是使用主题 simple :)

<s:iterator value="myList"><s:radio theme="simple" name="someNameToSubmit" list="#{id:name}"/><br></s:迭代器>

这将使 name 作为标签，id 作为要提交的属性

I'm using a struts radio tag that is being populated with a list of objects that have two fields:

class MyAction {
     List<MyObject> myList;
     String selectedId
     public String execute() {
         ...
         myList = new ArrayList<MyObject>();
         myList.add(new MyObject("1","first object");
         myList.add(new MyObject("2","second object");
         myList.add(new MyObject("3","second object");
         ...
     }

     // Getters and Setters for myList & selectedId
     ...
}

class MyObject {
    String id;
    String name;

    MyObject(String id, String name) {
         this.id = id;
         this.name = name;
    }
    // Getters and Setters for id & name
    ...
}

Here's what I was using on my page to display the list of radio buttons

<s:radio key="selectedId" list="myList" listKey="id" listValue="name"/>

However, this yields a horizontal list of radio buttons. I tried adding a css style to them:

<style>
    .vertical input { display: block; }
</style>

But this causes the labels and the radio buttons to show up on separate lines as well, instead of the radio button and label on the same line:

first object

second object

third object

what I want is:

first object

second object

third object

解决方案

its actually simple, i mean use theme simple :)

<s:iterator value="myList"> 
  <s:radio theme="simple" name="someNameToSubmit" list="#{id:name}"/><br>
</s:iterator> 

This will make name as a label and id as the property to submit
