Make a list with multiple pages in Jquery

I'm making a page with a list of products (which are loads using ajax) but i want to show only 6 products/page but i don't know how to do it and i don't find any examples that implements what i want. So for example if i have 20 products i want to show 6 in the first page, 6 in the second, .. etc to the last product in the last page (the page is always the same only the products change).
So in the end of the page i must have page 1-n
Can someone help me?
this is the js that load the products and show them one below the other:
$(document).ready(function () {
$.ajax({
type: "GET",
url: "json/projects.json",
dataType: "json",
success: function (data) {
showInfo(data);
},
});
});
function showInfo(data) {
var htmlString = "";
if (data.length == 0) {
htmlString =
"<span id = " +
"message>" +
"Non è stato trovato alcun progetto" +
"</span>";
$("#list").append(htmlString);
} else {
//altrimenti stampo data
for (i = 0; i < data.length; i++) {
//scorro tutto il mio file json
htmlString =
"<div class = " + "project id = " + data[i].id + ">" +
"<div class =" + "row-list>" +
"<div class = " + "title>" + data[i].title + "</div>" +
"<div class = " + "info>" + "<img src = " + "img/user.png>" + data[i].username + "</div>" +
"<div class = " + "info>" + "<img src = " + "img/budget.png>" + data[i].budget + "</div>" +
"<div class = " + "info>" + "<img src = " + "img/data.png>" + data[i].data + "</div>" +
"<div class = " + "flag>" + data[i].flag + "</div>" +
"</div>";
// collego al div #list le informazioni
$("#list").append(htmlString);
}
// aggiungo l'handler per visualizzare i dettagli quando un progetto viene cliccato
$(".project").click(function () {
window.location.href = "details.php?id=" + $(this).attr("id");
});
}
}

If the page doesn't change, you can stay on the same page while simply changing the products shown.
Here's a simplified version to demonstrate how this could work:
// create 20 product names
let products = [];
for (let i=1; i<=20; i++) {
products.push(`This is Product Name ${i}`);
}
let firstShown = 0;
const display = document.getElementById('display');
// display up to 6 products on page
function addToDisplay(first) {
display.innerHTML = '';
let last = Math.min(first+5, products.length-1);
for (let i = first; i <= last; i++) {
let li = document.createElement('li');
li.innerHTML = products[i];
display.appendChild(li);
}
}
function forward () {
display.innerHTML = '';
firstShown += 5;
addToDisplay(firstShown);
}
function back () {
display.innerHTML = '';
firstShown = Math.max(firstShown-5, 0);
addToDisplay(firstShown);
}
// show initial 6 producs
addToDisplay(firstShown);
<p>Display multiple products 6 at a time<br/>
<button type="button" onclick="back();">Back</button>
<button type="button" onclick="forward();">Forward</button>
</p>
<ul id="display"></ul>

Dynamic select drop down box returning null or undefined

I am trying to achieve a dropdown box in my webpage which lists the options from the values in the database. I have achieved showing the listed options for the dropdown, but when I select the option it is not set to a value. In other words I have a doubt whether my dropdown is initialized or not.
I have added the required snippet for the action.
function add_row() {
table = document.getElementById('b_book');
var rowData = document.createElement('tr');
rowData.innerHTML = '<td>' + slno +
'</td><td id="dbSNO"><select id="SNO[' + slno + ']" onchange="detail_fetcher(this.value)" onselect="detail_fetcher(this.value)" onload="detail_fetcher(this.value)"></select></td>' +
'<td id="dbLNO"><input type="text" id="LNO[' + slno + ']" list="lot_srch_list" onkeydown="LNO_COL(event,this.value,this.id)" onfocus="lotNo_select()"/></td>' +
'<td><input type="text" id="dbMTR[' + slno + ']"/></td><td id="dbWT[' + slno + ']"></td><td id="dbMWT[' + slno + ']"></td><td id="GPM[' + slno + ']"></td><td id="dbTONE[' + slno + ']"></td><td><button id="btn_rem[' + slno + ']" onclick="remove_row()">Remove</button></td>';
table.appendChild(rowData);
slno += 1;
}
function LNO_COL(e, lno, hashtag) {
var beg_pos = hashtag.indexOf('[') + 1;
var end_pos = hashtag.indexOf(']');
var hash_pos = hashtag.substring(hashtag.lastIndexOf('[') + 1, hashtag.lastIndexOf(']'));
var postIN = 'par=' + parname.value + '&lno=' + lno;
if (e.ctrlKey) {
sNo_list = document.getElementById('SNO[' + hash_pos + ']');
sNo_list.innerHTML = '';
var XMLhLNO = new XMLHttpRequest();
XMLhLNO.onreadystatechange = function () {
if ((this.readyState === 4) && (this.status === 200)) {
var result = this.responseText;
var JSON_result = JSON.parse(result);
for (z in JSON_result) {
var sno_opt;
sno_opt = document.createElement('option');
sno_opt.value = JSON_result[z].slno;
sno_opt.text = JSON_result[z].slno;
sNo_list.appendChild(sno_opt);
}
}
};
XMLhLNO.open('POST', 'sno_lot_par2.php', true);
XMLhLNO.setRequestHeader('Content-type', 'application/x-www-form-urlencoded')
XMLhLNO.send(postIN);
detail_fetcher(hashtag);
}
}
function detail_fetcher(hash_position) {
var row_no = hash_position.substring(hash_position.lastIndexOf('[') + 1, hash_position.lastIndexOf(']'));
var serial_row = document.getElementById('SNO[' + row_no + ']');
alert(serial_row.);
/* var XMLfetcher = new XMLHttpRequest();
XMLfetcher.onreadystatechange = function()
{
if((this.readyState == 4)&&(this.status == 200))
{
var src_result = this.responseText;
var JSON_res = JSON.parse(src_result);
alert(serial_row_db);
alert(src_result);
}
};
XMLfetcher.open('POST','srch_lot2.php',true);
XMLfetcher.setRequestHeader('Content-type','application/x-www-form-urlencoded');
XMLfetcher.send(('row=' + serial_row_db));
*/
}
I have tried using value method, selecteditem(index) method but none of them proves to be successful.
Note: I want to use pure JavaScript as I am quite confused with using jQuery.

Multiple Group By using two look-up columns which have multi valued selection enabled on an SP 2013 list using JavaScript

So I'm working on SP 2013 and have a document library which has three Lookup columns viz : Business Unit, Axis Product and Policy form. What I'm trying to do is I have managed to group by the List items first by Business Unit column and then by the Axis Product Column. This works fine but recently I'm trying to show the count of the number of items inside a particular Axis Product. Which would be like - Axis Product : "Some Value" (Count).
I'm able to show this count with Business Unit, but not able to do this with Axis Product. So I tried querying the library with both Business Unit and Axis Product to get the count for Axis Product, I'm not sure about this approach and currently I'm getting an error message:
'collListItemAxisProduct' is undefined.
Any help would be appreciated as I've been stuck on this for a long time now. Here is my code below :

// JavaScript source code

You have to call clientContext.executeQueryAsync after calling clientContext.load in order to populate any results from the SharePoint object model.
executeQueryAsync takes two parameters: first the function to execute on success, and second the function to execute if an error is encountered. Any code that depends on successfully loading values from the query should be placed in the on success function.

JS/HTML function

Can someone please help me understand why the function writeOptions logs optionCounter twice?
console.log("<option values=" + optionCounter + ">"+optionCounter);
Why is there a second optionCounter placed after the option element?
<script type = "text/javascript">
function writeOptions(startNumber,endNumber)
{
var optionCounter;
for(optionCounter = startNumber;
optionCounter <= endNumber; optionCounter++)
{
document.write("<option value=" + optionCounter + ">" + optionCounter);
}
}
function writeMonthOptions()
{
var theMonth;
var monthCounter;
var theDate = new Date(1);
for(monthCounter = 0; monthCounter < 12; monthCounter++)
{
theDate.setMonth(monthCounter);
theMonth = theDate.toString();
theMonth = theMonth.substr(4,3);
document.write("<option value=" + theMonth + ">" + theMonth);
}
}
function recalcDateDiff()
{
var myForm = document.form1;
var firstDay =
myForm.firstDay.options[myForm.firstDay.selectedIndex].value;
var secondDay =
myForm.secondDay.options[myForm.secondDay.selectedIndex].value;
var firstMonth =
myForm.firstMonth.options[myForm.firstMonth.selectedIndex].value;
var secondMonth =
myForm.secondMonth.options[myForm.secondMonth.selectedIndex].value;
var firstYear =
myForm.firstYear.options[myForm.firstYear.selectedIndex].value;
var secondYear =
myForm.secondYear.options[myForm.secondYear.selectedIndex].value;
var firstDate =
new Date(firstDay + " " + firstMonth + " " + firstYear);
var secondDate = new Date(secondDay + " " + secondMonth + " " + secondYear);
var daysDiff = (secondDate.valueOf() - firstDate.valueOf());
daysDiff = Math.floor(Math.abs((((daysDiff/1000)/60)/60)/24));
myForm.txtDays.value = daysDiff;
}
function window_onload()
{
var theForm = document.form1;
var nowDate = new Date();
theForm.firstDay.options[nowDate.getDate() - 1].selected =true;
theForm.secondDay.options[nowDate.getDate() - 1].selected = true;
theForm.firstMonth.options[nowDate.getMonth() - 1].selected = true;
theForm.secondMonth.options[nowDate.getMonth() - 1].selected = true;
theForm.firstYear.options[nowDate.getFullYear() - 1970].selected = true;
theForm.secondYear.options[nowDate.getFullYear() - 1970].selected = true;
}
</script>
as you can see this is the entire Javascript codeblock for this particular example.

I believe you know HTML. Each <option> tag has a display text (or label) and a value. And your code is creating the html option tag with both. So, when you write:
document.write("<option value=" + optionCounter + ">" + optionCounter);
the first optionCounter is for value and second one is for label/display text.
Note: I don't see the option tag being closed which could result in issues if not handled properly by the browser, so modify the statement as follows to render correct HTML:
document.write("<option value=" + optionCounter + ">" + optionCounter + "</option>");
Refer more about select tag & option tag on w3schools.com.

Adding Delay between inserting data in row

I am recieving data (10 records at a time) and inserting it in a div in a javascript loop
var a1 = $('.HomeAnnoucement').length;
var a2 = $('.HomeAnnoucement').length;
for (a1 ; a1 < (+a2 + +data.d.length) ; a1++) {
var a = a1 - a2;
var newFormat = '<div class="HomeAnnoucement"><label class="annID" id="archannouncementID' + a1 + '" style="display: none;" /><div class="DateandDelete left"><a class="AnnoucementDate left"><strong>' + data.d[a].EffectiveDate.split('/')[1] + getPostWord(parseInt(data.d[a].EffectiveDate.split('/')[1])) + '</strong> ' + getMonthString(parseInt(data.d[a].EffectiveDate.split('/')[0])) + '</a><div class="clear"></div></div><a class="AnnoucementTitle left"><strong id="archannTitle' + a1 + '" class="bold"></strong></a><div class="clear"></div></div><div class="AnnoucementDescription" id="archannDescription' + a1 + '" style="display:none;"></div>';
$('#archivedAnnouncements').append(newFormat);
$('#archannouncementID' + a1).append(data.d[a].ID);
$('#archannTitle' + a1).append(data.d[a].Title);
if (data.d[a].Owner != "" && data.d[a].Owner != " ") {
$('#archannTitle' + a1).append('<label style="font-weight: normal !important;"> by ' + data.d[a].Owner + '</label>');
}
var description = data.d[a].Description.replace(/\"/g, "'");
var div = document.createElement("div");
div.innerHTML = description;
var descriptiontext = div.textContent || div.innerText || "";
$('#archannDescription' + a1).html(data.d[a].Description);
}
I want to add delay in between inserting the rows. So that the user could see each record insertion in the grid. I have tried inserting the elements with display: none and fadingIn setTimeOut function but that didnt work. Please help.

Use JQuery Show with animation
Here is sample quoted form page above
<!DOCTYPE html>
<html>
<head>
<style>
p { background:yellow; }
</style>
<script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
<button>Show it</button>
<p style="display: none">Hello 2</p>
<script>
$("button").click(function () {
$("p").show("slow");
});
</script>
</body>
</html>
In this case you can add hidden controls to child list, and call show with animation in loop

JQuery .delay() would help you
http://api.jquery.com/delay/

I've modified your existing code to hide each row and then set a delay and fadeIn...
var a1 = $('.HomeAnnoucement').length;
var a2 = $('.HomeAnnoucement').length;
