基于jquery异步传输json数据格式实例代码

前端技术 2023/09/05 JavaScript

1.jsp代码如下

复制代码 代码如下:

<%@ page language=\"java\" contentType=\"text/html; charset=UTF-8\"
    pageEncoding=\"UTF-8\"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+\"://\"+request.getServerName()+\":\"+request.getServerPort()+path+\"/\";
%>
<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\" \"http://www.w3.org/TR/html4/loose.dtd\">
<html>
<head>
<meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\">
<title>Insert title here</title>
<script type=\"text/javascript\" src=\"<%=basePath%>js/jquery-1.8.1.js\"></script>
</head>
<script type=\"text/javascript\">
 $(function(){
  $(\"#getResult\").click(function(){
   $.ajax({
    type:\"post\",
    url:\"<%=basePath%>jsonAction!getData.action\",
    dataType:\"json\",
    data:{\'param1\':$(\"#param1\").attr(\"value\"),\'param2\':$(\"#param2\").attr(\"value\")},
    success:function(returnData){
     var html = \"<table border=\'1\'><tr><td>编号</td><td>姓名</td><td>描述</td></tr>\";
     for(var i = 0; i < returnData.length; i++){
      html += \"<tr><td>\"+returnData[i].id+\"</td><td>\"+returnData[i].name+\"</td><td>\"+returnData[i].description+\"</td></tr>\";
     }
     $(\"#result\").html(html);
    }
   });
  });

 });
</script>
<body>
 <input type=\"text\" value=\"haha\" id=\"param1\">
 <input type=\"text\" value=\"hehe\" id=\"param2\">
 <div  id=\"result\"></div>
 <input type=\"button\" value=\"获取\" id=\"getResult\">
</body>
</html>

2.访问 action代码如下

复制代码 代码如下:

public class JsonAction extends ActionSupport{
 public void getData() throws IOException
 {
  HttpServletRequest req = ServletActionContext.getRequest();
  String p1 = req.getParameter(\"param1\");
  String p2 = req.getParameter(\"param2\");

  HttpServletResponse rep = ServletActionContext.getResponse();
  rep.setContentType(\"text/json;charset=utf-8\");
  PrintWriter pw = rep.getWriter();
  String data = \"[{\\\"id\\\":\\\"01\\\",\\\"name\\\":\\\"zhongqian\\\",\\\"description\\\":\\\"\"+p1+\"\\\"},{\\\"id\\\":\\\"02\\\",\\\"name\\\":\\\"zhangsan\\\",\\\"description\\\":\\\"\"+p2+\"\\\"}]\";
  pw.print(data);
  pw.flush();
 }
}
