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

Solution 1

calculate page count than via a loop create links to pages.

//Pagination
	pageSize = 8;

	var pageCount =  $(".line-content").length / pageSize;
    
     for(var i = 0 ; i<pageCount;i++){
        
       $("#pagin").append('<li><a href="#">'+(i+1)+'</a></li> ');
     }
        $("#pagin li").first().find("a").addClass("current")
    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">
         
</ul>

Solution 2

You need to count the pages using Math.ceil($(".line-content").size() / pageSize), and then dynamically add <li> for each page.

I have moved the initialization code inside $() (i.e. the Ready Event).

//Pagination
pageSize = 8;

$(function() {
  var pageCount = Math.ceil($(".line-content").size() / pageSize);

  for (var i = 0; i < pageCount; i++) {
    if (i == 0)
      $("#pagin").append('<li><a class="current" href="#">' + (i + 1) + '</a></li>');
    else
      $("#pagin").append('<li><a href="#">' + (i + 1) + '</a></li>');
  }


  showPage(1);

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

})

showPage = function(page) {
  $(".line-content").hide();

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

.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>

Solution 3

Place this somewhere it is executed when the DOM is ready, but before the click event handlers are added.

//How many pages do we want?
elementCount = $('.line-content').size();
pageCount = Math.ceil(elementCount / pageSize);

//Add the buttons.
buttons = '';
for(i=1; i<=pageCount; i++) {
    buttons += '<li><a href="#">' + i + '</a></li>');
}
$('#pagin').html(buttons);

Then you can just leave #pagin empty and the JavaScript will fill it for you:

<ul id="pagin">
</ul>

Disclaimar: I haven't tested this code.

//Pagination
	pageSize = 8;

	var pageCount =  $(".line-content").length / pageSize;
    
     for(var i = 0 ; i<pageCount;i++){
        
       $("#pagin").append('<li><a href="#">'+(i+1)+'</a></li> ');
     }
        $("#pagin li").first().find("a").addClass("current")
    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">4 I have some content</div>
<div class="line-content">5 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>

Solution 5

//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 {

<div class="line-content">12 I have some content</div>

<ul id="pagin">
