Dynamic pagination in Jquery

Question

I have this code :

//Pagination
	pageSize = 8;

	showPage = function(page) {
	    $(".line-content").hide();
	    $(".line-content").each(function(n) {
	        if (n >= pageSize * (page - 1) && n < pageSize * page)
	            $(this).show();
	    });        
	}
    
	showPage(1);

	$("#pagin li a").click(function() {
	    $("#pagin li a").removeClass("current");
	    $(this).addClass("current");
	    showPage(parseInt($(this).text())) 
	});

.current {
  color: green;
}

#pagin li {
  display: inline-block;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="line-content">1 I have some content</div>
<div class="line-content">2 I have some content</div>
<div class="line-content">3 I have some content</div>
<div class="line-content">4 I have some content</div>
<div class="line-content">5 I have some content</div>
<div class="line-content">6 I have some content</div>
<div class="line-content">7 I have some content</div>
<div class="line-content">8 I have some content</div>
<div class="line-content">9 I have some content</div>
<div class="line-content">10 I have some content</div>
<div class="line-content">11 I have some content</div>
<div class="line-content">12 I have some content</div>

<ul id="pagin">
            <li><a class="current" href="#">1</a></li>
            <li><a href="#">2</a></li>
            <li><a href="#">3</a></li>
            <li><a href="#">4</a></li>
</ul>

Instead of writing numbers manually in my HTML file, I want the numbers generate automatically according to the number of divs to display.

The code I have works but there is nothing in page 3 and 4. Instead of update the numbers in my HTML file, I want them to change dynamically with Jquery

//Pagination
pageSize = 8;

showPage = function(page) {
  $('.line-content').hide();
  $('.line-content:gt('+((page-1)*pageSize)+'):lt('+(page)*(pageSize-1)+')').show();
   $('.line-content:eq('+((page-1)*pageSize)+')').show();
}

var pgs = Math.ceil($('.line-content').length/pageSize);
var pgnt = '';
  for(var i=1;i<=pgs;i++){
	pgnt += '<li><a href="#">'+i+'</a></li>';
}
$('#pagin').html(pgnt);
$("#pagin li a").click(function() {
	
  $("#pagin li a").removeClass("current");
	$(this).addClass("current");
	showPage(parseInt($(this).text())) 
});
showPage(1);

.current {
  color: green;
}

#pagin li {
  display: inline-block;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="line-content">1 I have some content</div>
<div class="line-content">2 I have some content</div>
<div class="line-content">3 I have some content</div>
<div class="line-content">4 I have some content</div>
<div class="line-content">5 I have some content</div>
<div class="line-content">6 I have some content</div>
<div class="line-content">7 I have some content</div>
<div class="line-content">8 I have some content</div>
<div class="line-content">9 I have some content</div>
<div class="line-content">10 I have some content</div>
<div class="line-content">11 I have some content</div>
<div class="line-content">12 I have some content</div>

<ul id="pagin">

</ul>

This is inline to what you needed.
