Display a url response in the front-end

Question

I am able to get my url response in the console tag in google chrome. I need your help in displaying those values in my interface. The provided below code only enables me to display the first value in the url response.

main.js:

 try{
         var getNameOfEmployee = document.getElementById('getNameOfEmployeeID');

       function displayEmployee(){

            if (getNameOfEmployee.value != "") {
                 $("#someform").submit(function (event) {
                 event.preventDefault();
                 });
                 AjaxGet();
            }
            else{
                alert("Please enter any name of employee that you wish to know the extension code of!");
            }
       }

       AjaxGet = function (url, storageLocation, mySuccessCallback) {
             var result = $.ajax({
                 type: "GET",
                 url: 'http://localhost:8080/employee/' +$("#getNameOfEmployeeID").val(),
                 param: '{}',
                 contentType: "application/json",
                 dataType: "json",
                 success: function (data) {
                        storageLocation = data;
                        globalVariable = data;
                       console.log(storageLocation);
                       console.log(storageLocation.empName0.extCode);

                      var length = Object.keys(storageLocation).length;

                    var empArray = new Array(length);                   
                 }
             }).responseText ;
             return result;
             return  storageLocation;
             //console.log(result);
       } ; }

 catch(e){          document.getElementById("demo").innerHTML = e.message; }

My console is as:

empName0
:
{empName: "Aran", extCode: 5500}
empName1
:
{empName: "Bran", extCode: 5900}
empName2
:
{empName: "Cran", extCode: 5750}

Please somebody help me how to get all these results get printed in my index page once the submit button is clicked. Just now I tried JSON.stringify(storageLocation) and print the results on an alert message. Please provide me an answer to display the results which are now duplicated. If you need my java file which retrieves the data, it follows:

employeeDAO.java :

@Repository public class EmployeeDAO { private static final Map empMap = new HashMap();

 static { initEmps(); } private static void initEmps() { } public JSONObject getEmployee(String empName){ Map<String ,Employee> empMap2 = new HashMap<String ,Employee>(); String filePath="D:\\dummy.xls"; ReadExcelFileAndStore details = new ReadExcelFileAndStore(); List<Employee> myList= details.getTheFileAsObject(filePath); JSONObject emp1 = new JSONObject(); boolean check=false; int j=0; for (int i=0; i<myList.size(); i++) { if (myList.get(i).getEmpName().toLowerCase().contains(empName.toLowerCase())) 

{ emp1.put("empName"+j,myList.get(i)); j++; check = true; }

  } if(check == true) { //System.out.println("yes"); return emp1; } else { return null; } } public Employee addEmployee(Employee emp) { empMap.put(emp.getEmpName(), emp); return emp; } public Employee updateEmployee(Employee emp) { empMap.put(emp.getEmpName(), emp); return emp; } public void deleteEmployee(String empName) { empMap.remove(empName); } public List<Employee> getAllEmployees() { String filePath="D:/dummy.xls"; ReadExcelFileAndStore details = new ReadExcelFileAndStore(); return details.getTheFileAsObject(filePath); } public List<Employee> getAllImportantEmployees() { String filePath="D:/dummy.xls"; ReadImportantExtensionSheet impDetails = new ReadImportantExtensionSheet(); return impDetails.getTheFileAsObject(filePath); } } 

Answer 1

You could add some DOM manipulation inside you AJAX success method:

success: function (data) {
    storageLocation = data;
    console.log(storageLocation.empName0.extCode);
    $("#someform #someLabel").val(storageLocation.empName0.extCode);
    $("#someform #someOtherLabel").val(storageLocation.empName0.empName);
}

This will wait for the AJAX to complete and then update your page with the results.

You can use a jQuery each function to loop over each element in the results and update their corresponding elements on the page.

success: function (data) {
    storageLocation = data;
    $.each(storageLocation, function (index, value) {
        console.log(value.extCode);
        $("#someform #someLabel" + index).val(value.extCode);
        $("#someform #someOtherLabel" + index).val(value.empName);
    });
}

1. Have a table in your html
2. Upon receiving the response populate in UI

This is a sample code, change as per the json structure

  function load() { var resp = '[{"empName":"Aran","extCode":5500},{"empName":"Bran","extCode":5900},{"empName":"Cran","extCode":5750}]'; var emps = JSON.parse( resp ); var i; for(i=0; i<emps.length; i++) { $('#empdata').append('<tr><td>'+emps[i]['empName']+'</td><td>'+emps[i]['extCode']+'</td>...</tr>'); } } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <body> <table id="empdata" style="border: 1px solid;background-color: #eedaff;"> <th>Name</th><th>Ext</th> </table> <button onclick="load();">Load</button> </body>
