Question

I want to know about how to retrieve data from map.

I have three button.

Register, Update and Delete from Jsp page.

There are two JSP. First.jsp and Second.jsp.

I included first.jsp in second.jsp.aaa

The buttons are in second.jsp.

At First.jsp.

I have combobox for language change. It must be change language only when click button.

There are two language English and Japanese.

I send API class using ajax according to language id. If id=1(Japanese) and id=2(English).

I Wrote ajax api inside of combobox change function. Below is my code.

 $.ajax({
        url : 'aa/idsend',
        cache : false,
        type : 'GET',
        dataType : 'json',
        contentType : 'application/json; charset=utf-8',
        data : "lid="+select,
              success: function(data) {
               },
            }); 

I receive data from server the following format.

{data = Object {1: "Would you like to register?", 2: "Would you like to update?", 3: "Would you like to delete?"}

Above data are come from database. If I add new data into database the id become 4:"something have".

I want to know how to retrieve these data according button click event. If click register button I want to take register sentence only. The other is also like that.

Answer 1

It could be GET method also, but i prefer POST.

function ajaxRequest(dataObj, cbFunc) {
    $.ajax({
        method: 'POST',
        url: 'aa/idsend',
        data: dataObj
    }).done(function(dataFromServer) {
        cbFunc(dataFromServer);
    });
}

function useData(dataFS) {
    //do something with data from server dataFS
}

function getCurrentLanguage() {
  var cL = 'en';//default language
  //some code to get language from checkboxes
  return cL
}

$('.button').on('click', function(e) {
    var id = $(this).attr('id'),
        jsonData = {},
        curLang = getCurrentLanguage();

    switch (id) {
        case 'register' :
            jsonData = {req: 'register', lang: curLang};
            break;
        case 'update' :
            jsonData = {req: 'update', lang: curLang};
            break;
        case 'delete' :
            jsonData = {req: 'delete', lang: curLang};
            break;
        default:
            break;
    }

    ajaxRequest(jsonData, useData);
});

Then in the aa/idsend serverside script you can prepare data to send according to req POST variable received. Now you even don't need to send back questions like 'Would you like to register?'. Instead you can do action according to req value and send back information about the operation - Success! or Fail!
