1.第一个例子:
<s:select list="{'aa','bb','cc'}" theme="simple" headerKey="00" headerValue="00"></s:select>
2.第二个例子:
<s:select list="#{1:'aa',2:'bb',3:'cc'}" label="abc" listKey="key" listValue="value" headerKey="0" headerValue="aabb">
3.第三个例子:
<%
java.util.HashMap map = new java.util.LinkedHashMap();
map.put(1,"aaa");
map.put(2,"bbb");
map.put(3,"ccc");
request.setAttribute("map",map);
request.setAttribute("aa","2");
%>
<s:select list="#request.map" label="abc" listKey="key" listValue="value"
value="#request.aa" headerKey="0" headerValue="aabb"></
s:select
>
headerKey headerValue 为设置缺省值
4.第四个例子
public class Program implements Serializable {
/** serialVersionUID */
private static final long serialVersionUID = 1L;
private int programid;
private String programName;
public int getProgramid() {
return programid;
}
public void setProgramid(int programid) {
this.programid = programid;
}
public String getProgramName() {
return programName;
}
public void setProgramName(String programName) {
this.programName = programName;
}
}
在 xxx extends extends ActionSupport {
private List<Program> programs ;
public List<Program> getPrograms() {
return programs;
}
public void setPrograms(List<Program> programs) {
this.programs = programs;
}
}
在jsp页面
<s:select list="programs " listValue="programName " listKey="programid " name="program" id="program"
headerKey="0l" headerValue=" " value="bean.programid "
></s:select>
红色部分为在action里面的list,黄色为<option value="xxx">value</option>对应bean里面的字段programName
绿色为<option value="xxx",对应bean里面的字段programid
紫色为设定select被选中的值,s:select 会自动在 bean选中 key对应的值
