修改Struts2表单错误提示的显示样式
表单代码：
<s:form action="userRegisterAction" method="post"><s:textfield name="username" required="true" label="用户名"></s:textfield><br/><s:password label="密码" name="userpass" required="true" requiredposition="left"></s:password><br/><s:radio list="#{1:'男',0:'女'}" name="sex" requiredposition="left" label="性别"></s:radio><br/><s:select list="{'请选择省份','江苏','北京','上海','广州'}" name="province" requiredposition="left" label="省份"></s:select><br/><s:checkboxlist list="{'C','Java','C#'}" name="goodat" label="特长"></s:checkboxlist><br/><s:textarea rows="5" cols="30" name="description" requiredposition="left" label="描述"></s:textarea><br/><s:submit value="注册"></s:submit><s:reset value="清空"></s:reset></s:form>
userRegisterAction.java很简单：
public class UserRegisterAction extends ActionSupport {/** * @author lovemu * 用户注册 */private static final long serialVersionUID = -6342452733015612274L;private String username; //用户名private String userpass; //密码private int sex; //性别private String province; //省份private String[] goodat; //特长private String description; //描述public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getUserpass() {return userpass;}public void setUserpass(String userpass) {this.userpass = userpass;}public int getSex() {return sex;}public void setSex(int sex) {this.sex = sex;}public String getProvince() {return province;}public void setProvince(String province) {this.province = province;}public String[] getGoodat() {return goodat;}public void setGoodat(String[] goodat) {this.goodat = goodat;}public String getDescription() {return description;}public void setDescription(String description) {this.description = description;}public String execute() throws Exception{return SUCCESS;}}execute()方法中只有一句,用于测试
错误信息显示为：
更改表单为：
<s:form action="userRegisterAction" method="post" theme="simple"><label>用户名：</label><s:textfield name="username" required="true"></s:textfield><br/><label>密 码：</label><s:password label="密码" name="userpass" required="true" requiredposition="left"></s:password><br/><label>性 别：</label><s:radio list="#{1:'男',0:'女'}" name="sex" requiredposition="left"></s:radio><br/><label>省 份：</label><s:select list="{'请选择省份','江苏','北京','上海','广州'}" name="province" requiredposition="left"></s:select><br/><label>特 长：</label><s:checkboxlist list="{'C','Java','C#'}" name="goodat"></s:checkboxlist><br/><label>描 述：</label><s:textarea rows="5" cols="30" name="description" requiredposition="left"></s:textarea><br/><s:submit value="注册"></s:submit><s:reset value="清空"></s:reset></s:form>
再添加一句：
<s:fielderror cssStyle="color:red"></s:fielderror>
将会使提示信息变为：
这样再适当修改下样式,就可以很美观的将错误提示信息集中显示在一个地方
其中关键地方就是在表单中添加一句：theme="simple"
然后,就是在自己想要显示错误样式的地方，比如<div></div>里，
添加一句：<s:fielderror cssStyle="color:red"></s:fielderror>
