How to reload ajax call function in given time

Tags:

I had a task to do which I have accomplished almost but I have been stuck to a last part.

What I am doing

I have JSON data from back end which I am calling at once then showing it as a HTML table but only 10 rows at a Time,If rows are more than 10 then it will show in two parts first 10 then after 5 seconds next 10, You can check my snippet for that
When it will be the last page of table, then what I am doing is showing an Image, If Image is one then table-->Image if there are more than one Image suppose 2 images there than table-->image1-->table-->image2 like this it is working
When once the cycle is completed like table-->image then I am calling table function once again because it will have dynamic data
Here the Image data is also coming in JSON and it is also dynamic there I am facing issue

Issue

I have a function imageFormatter() which is having data for Image in JSON format
These Images are set in my database as column name IsActive so when I am calling this data I am checking for this condition in my db via query
Now my table is showing up on UI and iamges are also, but in my database that IsActive flag can be changed at any time from Y to N
Now what I am trying to do is I want the function imageFormatter() to get refreshed at every 5 seconds so that it can take the new data
To change that IsActive I have a UI which user is handeling on click of go whatever Image user selects I am saving it to db via servlet, now Just want to show call this imageFormatter() so that it can take newest Images

This is the approach I am using to do my task. Is there a better approach?

I have commented all the lines in my code for better understanding

function myFun() {
  imageFormatter(); // here  I am calling because it will call again and again
  $.ajax({

    url: "MenuCounter",
    method: "GET",
    data: {
      counterCode: counterCode
    },
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    success: function(tableValue) {

      // tableValue i have provided in my code/post

      if (tableValue[0].outlet === 'NoData') {
        $.alert({
          title: 'Alert!',
          content: 'Display content Not available',
          onDestroy: function() {

          }
        });
      } else {

        addTable(tableValue, color1, color2, color3, color4) // colors are some colors
        showRows();

        interval = window.setInterval(showRows, 5000);



      }

    }
  });
}

$.ajax({
  async: true,
  url: "MenuCounterName",
  method: "GET",
  dataType: "json",
  data: {
    counterCode: counterCode
  },
  contentType: "application/json; charset=utf-8",
  success: function(data) { // geting counter name to display on to such as `Dosa Corner`
    if (data[0].outlet === 'NoData') {
      $.alert({
        title: 'Alert!',
        content: 'Display content Not available',
        onDestroy: function() {

        }
      });
    } else {
      // console.log(data[0]["Counter name"])
      $("#counterName").text(data[0]["Counter name"])
      color1 = data[0].Color1;
      color2 = data[0].Color2;
      color3 = data[0].Color3;
      color4 = data[0].Color4;

      myFun(); // this function is calling data from db

      $(".loader").hide();
      $(".overlay").hide();

    }
  }
});

function hideImage() {
  var imgno = (cnt % imgLen) + 1;
  $("#displayImage img").css("display", "none");
  $("#displayImage img:nth-child(" + imgno + ")").css("display", "block")

  $("#displayImage").show(); // show Image and hide table
  $("#DisplayTable").hide();

  setTimeout(function() {
    myFun();
    // I am calling my function after the last image is shown because it will call from db

  }, 5000);
  cnt++;
}


function showRows() {

  if ($(".hidden:lt(11)").length > 0) {
    $("tr:not(.hidden):not(.already-shown)").addClass("already-shown");

    hideImage();

    clearInterval(interval);

Edit / Update

It will be easier If I refresh the whole page when a user clicks button

My second approach is, I have a HTML table where I am having table-->image, and on other table I am having a Ui where user selects which Image to be displayed then I take that values with Image name and if checkbox is checked then save to database with name ans IsActive as Y if it is not check than saved in db as N

So what I thought is when user clicks on button on setting Image page I am saving that to database so from that Java servlet can I refresh the other HTML page so that it take latest data from db

I am calling my function once it is the last row, same I am doing it with Image but it is taking time and not rendering correctly I am calling My function addTable(tablevalue) after the Image is shown because, that may have dynamic data, so what i am trying to do is calling imageFormatter(); also with that so when table data loades it will also refresh the data

Image inside imageformater

{"A":["CountA1.jpg"]} // when only one is active
{"A":["CountA1.jpg","CountA2.jpg"]} // when two are active these are dynamic

As my myFun is calling again after the Image, there I am trying to call imageFormater so that it also refresh the function so new data come

Idea

As per my code flow if there are more than one image then UI will show as table-->image1>table-->image2-->table>--image3 this is when there are three images so what I have thought of when it is the last image in above case image3 I should location.reload();. But I am not able to find which Image is last

Here in my static code, after countA2.jpg image I want to reload the page

Edit / Update

Please check out @Don'tDownVote code -:

  function hideImage() {
                if(imgLen){
                  var imgno = (cnt % imgLen) + 1;
                  if(imgno == 1 && !lastImage){
                    lastImage = true;
                  }else if(imgno == 1 && lastImage){
                    console.log("reload now") // not entering in this condition
                    location.reload();
                  }
                  console.log(imgno)
                  $("#displayImage img").css("display", "none");
                  $("#displayImage img:nth-child(" + imgno + ")").css("display", "block")

                  $("#displayImage").show();
                  $("#DisplayTable").hide();
                  setTimeout(function() {
                    initTable(tableValue);
                  }, 10000);
                  cnt++;
                 } else{
                  initTable(tableValue);
                 }

              }

It is not entering the else if condition, My all the problems because of displaying multiple Images one after other including table, if there would have been only one Image I could have easily reloaded my page, here I have table-->image1>table-->image2 after Image 2 I want to reload.

I am trying to reload or refresh the page after the last page in above condition it is Image2.

Try this. I have added the logic to reload when it is last image.

$(document).ready(function() {

      var imgLen = 0;
      var cnt = 0;
      var lastImage = false;

      var tableValue = [{
      "Item Name": "MANCHOW  V SOUP",
