Pagination for javascript/nodejs

usage example

var paginator = pagination.create('search', {prelink:'/', current: 1, rowsPerPage: 200, totalResult: 10020});
console.log(paginator.render());

Or customized renderer

This example show how to generate markup for twitter boostrap, see example/twitter.html for template rendering

var pagination = require('pagination')

var boostrapPaginator = new pagination.TemplatePaginator({
	prelink:'/', current: 3, rowsPerPage: 200,
	totalResult: 10020, slashSeparator: true,
	template: function(result) {
		var i, len, prelink;
		var html = '<div><ul class="pagination">';
		if(result.pageCount < 2) {
			html += '</ul></div>';
			return html;
		}
		prelink = this.preparePreLink(result.prelink);
		if(result.previous) {
			html += '<li class="page-item"><a class="page-link" href="' + prelink + result.previous + '">' + this.options.translator('PREVIOUS') + '</a></li>';
		}
		if(result.range.length) {
			for( i = 0, len = result.range.length; i < len; i++) {
				if(result.range[i] === result.current) {
					html += '<li class="active page-item"><a class="page-link" href="' + prelink + result.range[i] + '">' + result.range[i] + '</a></li>';
				} else {
					html += '<li class="page-item"><a class="page-link" href="' + prelink + result.range[i] + '">' + result.range[i] + '</a></li>';
				}
			}
		}
		if(result.next) {
			html += '<li class="page-item"><a class="page-link" href="' + prelink + result.next + '" class="paginator-next">' + this.options.translator('NEXT') + '</a></li>';
		}
		html += '</ul></div>';
		return html;
	}
});
console.log(boostrapPaginator.render());

OR

var pagination = require('pagination');
var paginator = new pagination.SearchPaginator({prelink:'/', current: 10, rowsPerPage: 200, totalResult: 10020});
console.log(paginator.render());
// output (without newlines)

<div class="paginator">
	<a href="/?page=9" class="paginator-previous">Previous</a>
	<a href="/?page=8" class="paginator-page paginator-page-first">8</a>
	<a href="/?page=9" class="paginator-page">9</a>
	<a href="/?page=10" class="paginator-current">10</a>
	<a href="/?page=11" class="paginator-page">11</a>
	<a href="/?page=12" class="paginator-page paginator-page-last">12</a>
	<a href="/?page=11" class="paginator-next">Next</a>
</div>

OR need data from the calculation

var pagination = require('pagination');
var paginator = new pagination.SearchPaginator({prelink:'/', current: 3, rowsPerPage: 200, totalResult: 10020});
console.log(paginator.getPaginationData());

// output
{ prelink: '/',
  current: 3,
  previous: 2,
  next: 4,
  first: 1,
  last: 51,
  range: [ 1, 2, 3, 4, 5 ],
  fromResult: 401,
  toResult: 600,
  totalResult: 10020,
  pageCount: 51 }

Pagination on client side

<html>
	<head>
	<script src="../release/pagination.full.min.js"></script>
	</head>
	<body>
		<div id="paging"></div>
		<script type="text/javascript">
		(function() {
			var paginator = new pagination.ItemPaginator({prelink:'/', current: 3, rowsPerPage: 200, totalResult: 10020});
			var html = paginator.render();
			var paginator = pagination.create('search', {prelink:'/', current: 1, rowsPerPage: 200, totalResult: 10020});
			html += paginator.render();
			document.getElementById("paging").innerHTML = html;
		})();
		</script>
	</body>
</html>

You can browse example folder for more. Release folder contains all mimified versions for browser. To customize your need you can use ./bin/build.js -h html += paginator.render();
