Question

Servlet

 String getCodeList = (new JSONArray(rmsCodeList)).toString();
 response.setContentType("application/json");
 response.setCharacterEncoding("UTF-8");
 response.getWriter().write(getCodeList);

Jquery

$(document).ready(function() {
var getdata;
$.post("GetItemCode", function(data) {
    getdata=data;

});
}); 

working fine, I get the complete array on getdata

Write Two

 String getCodeList = (new JSONArray(rmsCodeList)).toString();
 response.setContentType("application/json");
 response.setCharacterEncoding("UTF-8");
 response.getWriter().write(getCodeList);


 String getNameList = (new JSONArray(rmsNameList)).toString();
 response.setContentType("application/json");
 response.setCharacterEncoding("UTF-8");
 response.getWriter().write(getNameList);

How can I get two array on different variable

$(document).ready(function() {
var getdata1;
var getdata2;
$.post("GetItemCode", function(data) {
    getdata1=?;
    getdata2=?;

});
}); 

Answer 1

Put the two arrays in a JSONObject and retrieve it in Javascript

response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
response.getWriter().write(
    new JSONObject()
        .put("codeList", new JSONArray(rmsCodeList))
        .put("nameList", new JSONArray(rmsNameList)).toString()
);

Then in Javascript you retrieve it as a property of the returned object.

$(document).ready(function() {
    var getdata1;
    var getdata2;
    $.post("GetItemCode", function(data) {
        getdata1 = data.codeList;
        getdata2 = data.nameList;
    });
});
