javascript - How to display Image dynamically on UI?

Question

I am working on Displaying a screen which is consist of HTML table and Image, an HTML table is fully dynamic.

Code working process

When user is loading a page (With URL) I am rendering a HTML table in different parts which means that page is loaded. I am Getting all the table data in 'JSON' format at once and then showing 3-3 rows at a time on UI in the gap(Interval) of 3 seconds When full table is loaded Then I am showing The Image for some time and after that again loading Table and showing image once table is loaded, So it is working fine,Now what I am trying to do is Show the Image dynamically

What I am trying to do

Currently I am doing it like <img src="Image/Counter A/CounterA1.jpg" alt="Some Image" width="460" height="345"> because there was only one Image to Show in folder, but now Counter A has two Images or 3 or whatever it may be So When Page is loading I am getting the Which Image is to be loaded in object like this var images = {"Counter A":["CounterA1.jpg", "CounterA2.jpg"]} for Counter A there are Two Images similarly for other counters also, SO what I am trying to do is Load table first then, When loading table completed trying to show first Image than again load table than show Image 2 That's why I have Images link inside an array, my only Issue is to show one Image at a Time

Working process

Table loading -> after 3seconds -> next 3 rows of table until the last page of table -> show Image1 (CounterA1.jpg) -> load table again -> show Image2(CounterA2.jpg) ->then again table -> then again Image1 because there are only two Images

I have already done showing HTML table and showing Image with only one Image and statically now I want to do That dynamically

Answer 1

Try like this.

I have introduced a new function to format image in HTML. and then got its length and loop introduced a cnt(count) variable and made it to increment. and used modulo to find the number and repeated the images.

var imgLen = 0;
var cnt = 0;

var tableValue = [{
    "Item Name": "MANCHOW  V SOUP",
    "SellingPrice": 100
}, {
    "Item Name": "SMIRNOFF GREEN APPLE 60",
    "SellingPrice": 202
}, {
    "Item Name": "SMIRNOFF GREEN APPLE30",
    "SellingPrice": 101
}, {
    "Item Name": "BOMBAY SAPHIRE 750",
    "SellingPrice": 472

    "SellingPrice": 191
}, {

    "SellingPrice": 877
}, {
