一、jar包
首先引入Struts和json所需的jar包。
二、前台代码
<body>
<form id="myform">
<table>
<tr>
<td>姓名:</td>
<td> <input type="text" name="name" /> </td>
</tr>
<tr>
<td>性别:</td>
<td>
<input type="radio" name="sex" value="1"> 男
<input type="radio" name="sex" value="0"> 女
</td>
</tr>
<tr>
<td>年龄:</td>
<td>
<select name="age">
<option value="20">20</option>
<option value="21">21</option>
<option value="22">22</option>
</select>
</td>
</tr>
<tr>
<td colspan="2">
<input type="button" id="ajaxBtn" value="提交" />
</td>
</tr>
</table>
</form>
<div id="msg"></div>
</body><script type="text/javascript">
$(function() {
$("#ajaxBtn").click(function() {
var params = $("#myform").serialize();
$.ajax( {
type : "POST",
dataType : "json",
url : "RegisterAction.action",
data : params,
success : function(data) {
var obj = eval(‘(‘ + data + ‘)‘); //将数据转换为json类型
$("#msg").html("您提交的信息为： 姓名："+obj.name+" , 性别："+obj.sex+" , 年龄："+obj.age);
},
error : function(data, status, e){
alert("error");
}
});
})
})
</script>import java.util.HashMap;
import java.util.Map;
import net.sf.json.JSONObject;
public class RegisterAction {
private String name;
private String sex;
private String age;
private String result;
public String register() {
Map<String, Object> map = new HashMap<String, Object>();
map.put("msg", true);
map.put("name", name);
map.put("sex", sex==null?"":("1".equals(sex)?"男":"女"));
map.put("age", age);
JSONObject json = JSONObject.fromObject(map);//将map对象转换成json类型数据
result = json.toString();// 将result传给页面
return "success";
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
