struts2——s:doubleselect标签！！！

2010-10-21 10:34 197 查看

doubleselect：
1）<s:doubleselect标签必须要放在<s:form>里面。
2) <s:doubleselect标签默认是竖着显示，要横着显示也很麻烦，要覆盖strut2的css或者覆盖struts2的方法。3）在使用<s:doubleselect标签的时候加上headerKey和headerValue属性出现显示不完整的情况。
4）一级列表需要一个list，而二级列表需要一个map。
5）top代码一级列表当前选中的项。map.get(top.deptno)代表根据部门编号找到map里面对应的员工集合。6）一个jsp页面上出现了两个<s:doubleselect标签也存在显示不完全的现象。

}
public Map getMap() {

dto：

public class UserInfo {
private String userno;
private String username;
public UserInfo() {

}
public UserInfo(String userno, String username) {
this.userno = userno;
this.username = username;
}
public String getUserno() {
return userno;
}

public void setUserno(String userno) {
this.userno = userno;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}

public class DeptInfo {
private String deptno;
private String deptname;
public DeptInfo() {
}
public DeptInfo(String deptno, String deptname) {
this.deptno = deptno;
this.deptname = deptname;
}
public String getDeptno() {
return deptno;
}
public void setDeptno(String deptno) {
this.deptno = deptno;
}
public String getDeptname() {
return deptname;
}
public void setDeptname(String deptname) {
this.deptname = deptname;
}
}
