在jquery中使用來自servlet的json獲取兩個不同變量的數組

Question

Servlet的

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

jQuery的

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

});
}); 

工作正常，我在getdata上獲得完整的數組

寫兩個

 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);

如何在不同的變量上獲得兩個數組

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

});
}); 

Answer 1

發送包含兩個數組值的JSON對象，並將每個數組值設置為所需的JavaScript變量。

雖然您正在編寫代碼，就像您正在進行同步調用一樣，這可能會導致問題。

Answer 2

將兩個數組放在JSONObject並在Javascript中檢索它

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

然后在Javascript中將其檢索為返回對象的屬性。

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