如何在.jsp文件中接收Ajax发送的数组

Question

Hi I wrote the below js code to send two arrays to a jsp file 嗨，我写了下面的js代码，将两个数组发送到jsp文件

$.post("scriptlet.jsp",
{ sg: array1[], st: array2[] },
function(data){
   alert("Data Loaded: " + data);
}
);

How do I retrieve them form the jsp side? 如何从jsp端检索它们？ I tried doing this inside scriptlet.jsp . 我尝试在scriptlet.jsp中执行此操作。 But didn't work 但没有奏效

<%
    String[] questionsList = (String)request.getParameter("sg");
%>

if i understand very well your problem , so you are trying to send JavaScript array to a jsp page , so here are my suggestion : 如果我非常了解你的问题，所以你试图将JavaScript数组发送到jsp页面，所以这是我的建议：

<script >
var tab = ["hello","world"]; //here is an array for test
$.get("scriptlet.jsp",{ sg:tab  },function(data){
        alert("Data Loaded: " + data);
    }
);
</script>
</head>
<body>
<% 

String[] myArray = request.getParameterValues("sg[]");
out.println(myArray[0]); // this will print you  "hello"
%>

</body>
