Let say I have a very long page of content consisting of multiple paragraphs which cannot be displayed in a single browser window with vertical scrollbar
<p>...very long sentence ...</p>
<p>...very long sentence ...</p>
<p>...very long sentence ...</p>
<p>...very long sentence ...</p>
So I want to cut the paragraphs and format them into multiple pages, e.g.
<!-- page 1 -->
<p>...very long sentence ...</p>
<p>...very long </p><!-- the ending p tag is automatic inserted since the following text cannot be displayed -->
<!-- page 2 -->
<p>sentence ...</p>
<p>...very long sentence ...</p>
<p>...very long sentence ...</p>
Are there any existing scripts for this purpose?
In the extreme case the paragraph might contain image, so each line might be variying in height.

Someone has created show/hide functionality with jQuery.
This may help you.

In case of paragraph with image and other html tags use below logic:
<div style="height:500px;overflow:hidden" id="blah">
Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.Hello Hello Hello.
</div>
<a href="#" id="showmore">Show more</a>
<script>
$("#showmore").live('click', function() {
$("#blah").css('height','1000px');
});
</script>

By using the below code you can paginate limitless paragraphs as according to your need.
jQuery:
$(document).ready(function(){
//how much items per page to show
var show_per_page = 5;
//getting the amount of elements inside content div
var number_of_items = $('#content').children().size();
//calculate the number of pages we are going to have
var number_of_pages = Math.ceil(number_of_items/show_per_page);
//set the value of our hidden input fields
$('#current_page').val(0);
$('#show_per_page').val(show_per_page);
//now when we got all we need for the navigation let's make it '
/*
what are we going to have in the navigation?
- link to previous page
- links to specific pages
- link to next page
*/
var navigation_html = '<a class="previous_link" href="javascript:previous();">Prev</a>';
var current_link = 0;
while(number_of_pages > current_link){
navigation_html += '<a class="page_link" href="javascript:go_to_page(' + current_link +')" longdesc="' + current_link +'">'+ (current_link + 1) +'</a>';
current_link++;
}
navigation_html += '<a class="next_link" href="javascript:next();">Next</a>';
$('#page_navigation').html(navigation_html);
//add active_page class to the first page link
$('#page_navigation .page_link:first').addClass('active_page');
//hide all the elements inside content div
$('#content').children().css('display', 'none');
//and show the first n (show_per_page) elements
$('#content').children().slice(0, show_per_page).css('display', 'block');
});
function previous(){
new_page = parseInt($('#current_page').val()) - 1;
//if there is an item before the current active link run the function
if($('.active_page').prev('.page_link').length==true){
go_to_page(new_page);
}
}
function next(){
new_page = parseInt($('#current_page').val()) + 1;
//if there is an item after the current active link run the function
if($('.active_page').next('.page_link').length==true){
go_to_page(new_page);
}
}
function go_to_page(page_num){
//get the number of items shown per page
var show_per_page = parseInt($('#show_per_page').val());
//get the element number where to start the slice from
start_from = page_num * show_per_page;
//get the element number where to end the slice
end_on = start_from + show_per_page;
//hide all children elements of content div, get specific items and show them
$('#content').children().css('display', 'none').slice(start_from, end_on).css('display', 'block');
/*get the page link that has longdesc attribute of the current page and add active_page class to it
and remove that class from previously active page link*/
$('.page_link[longdesc=' + page_num +']').addClass('active_page').siblings('.active_page').removeClass('active_page');
//update the current page input field
$('#current_page').val(page_num);
}
HTML:
<!-- the input fields that will hold the variables we will use -->
<input type='hidden' id='current_page' />
<input type='hidden' id='show_per_page' />
<!-- Content div. The child elements will be used for paginating(they don't have to be all the same,
you can use divs, paragraphs, spans, or whatever you like mixed together). '-->
<div id='content'>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
<p>Vestibulum consectetur ipsum sit amet urna euismod imperdiet aliquam urna laoreet.</p>
<p>and so on....</p>
</div>
<!-- An empty div which will be populated using jQuery -->
<div id='page_navigation'></div>
A while ago, I created pagify, a jQuery plugin to do just that. It detects page height by splitting elements into words and incrementally adding the words until the height reaches a specified height. I've given it some CSS to make it look like pages in the demo below, but you can style it to use 100% width and height. You can call it simply with $('body').pagify(options); The default options are as follows
{
'pageTag' : 'div', // the tag which surrounds each page
'pageClass': 'page', // the class of the page tag
'innerClass': 'page-inner', // the class of the inner page element
'pageSize': 'A4', // a class added to the page so that the size can be defined by css
'pageSizeClassPrefix': 'page-', // the prefix to the above class
'pageOrientation': 'portrait', // not yet used, but could be used to flip width and height
'splitElementClass': 'split-element' // elements which have been split across two pages are given this class
};
So to use 100% width and height:
html, body, page-screen-size {
width: 100%;
height: 100%;
}
and
$('body').pagify({
pageSize : 'screen-size'
});
Here it is in action: http://jsfiddle.net/nathan/nfHHE/

From what I understand this is very similar to the way an online reader works, where content is formatted into different pages or slides and it doesn't matter what the content inside it is, as this will adapt to its container.
In order to achieve your goal, I'd recommend CSS3 Multi-column layout (see http://www.w3.org/TR/2001/WD-css3-multicol-20010118/)
CSS
#your-container
{
width: 90%;
margin: 0 auto;
overflow: hidden; //Hide overflowing content
padding: 20px 0;
}
#div-inside-container //For padding and columns display purposes
{
position: relative;
-moz-column-count: 1;
-webkit-column-count: 1;
column-count: 1;
-moz-column-width: 50em;
-webkit-column-width: 50em;
column-width: 50em;
-webkit-column-gap: 0;
-moz-column-gap: 0;
column-gap: 0;
}
JQUERY
$(window).resize(function() {
//Resize container
$(div_content).height(Dimensions.TellMeHeight() - padding);
});
See example and code: http://jsfiddle.net/GLbXX/1/
