忽视它

我更熟悉JSP和java领域。我遇到了问题。我在下面提到了我的代码。

我的JSP代码：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org      /TR/html4/loose.dtd">
<html>
 <script src="http://code.jquery.com/jquery-1.9.1.js"></script>
 <script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>

 <script>

$(document).ready(function() {

$("#save").click( function ()
{


var arrayxx= new Array(5);
arrayxx[0]=0;
arrayxx[1]=3;
arrayxx[2]=4;
arrayxx[3]=9;





 $.get('Save1',{arrayX:arrayxx},function(responseJson) 
    {


} );



});
});







</script>
<head>


<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>

<input type="button" id="save" value="save" ></input>

</body>
</html>

我的servlet：

 import java.io.IOException;



    import javax.servlet.ServletException;

    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;



    public class Save1 extends HttpServlet {
private static final long serialVersionUID = 1L;


 public Save1() {
     super();

 }


 protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    System.out.println("INSIDE SERVLET");
    String [] yourList =  request.getParameterValues("arrayX");
    System.out.println(request.toString());
        System.out.println(yourList[0]);

}


protected void doPost(HttpServletRequest request, HttpServletResponse response)          throws ServletException, IOException {

    }

 }

我无法将数组从JSP传递给servlrt。请帮我解决一下这个。当我收到数组时，我发现该数组不包含任何元素。

提前致谢

根据您的要求，我建议您像这样使用ajax

$.ajax(
                {
                    type: "POST",
                    url: "servlet", //Your full URL goes here
                    data: { parametername: parametervalue},
                    success: function(data, textStatus, jqXHR){
                        //alert(data); 

}

忽略它--------------从jsp页面向servlet发送一个数组并在servlet中接收它------------忽略它
