Placing Large HTML content dynamically on TurnJs Flipbook

Question

I am not sure if this is something that has already been discussed, I tried searching on the list of issues but could not find anything related to it.

I have a large HTML content that I need to bind using turn.js. The problem I have is that, with turn js, I will have to split the HTML into separate div tags as pages. Is there a way in turn.js to bind the content on a div and it takes care of automatically wrapping to different pages based on the content that is being bound?

Or is there a way to know how much data needs to be bound to each page to get this scenario working.

Answer 1

According with the documentation (http://www.turnjs.com/docs/Method:_addPage) you can add dinamically pages. So when the page is loaded you can custom split your pages and add them dinamically. Something like this.

Imagine this HTML:

<div class="page">
    <h2>Title</h2>
    <p>Content</p>
</div>
<div class="page">
    <h2>Title</h2>
    <p>Content</p>
</div>
<div class="page">
    <h2>Title</h2>
    <p>Content</p>
</div>
<div class="page">
    <h2>Title</h2>
    <p>Content</p>
</div>
<div id="flipbook"></div>

We have here 4 pages but there are all in the same page, and the last element is where flipbook will be constructed. So when we load the page let's split them in Javascript:

$(document).ready(function() {
    // initialize the flipbook
    $("#flipbook").turn({page: 1, acceleration: true, gradients: true});

    // first we declare an array to store pages contents
    var pagesArray = [];
    $('.page').each(function() {
        // iterate through all pages and store the HTML inside
        pagesArray.push($(this).html());
    });

    // iterate the array and add pages dinamically
    for(var i in pagesArray) {
        // add the element within a div with the content that store before
        var element = $("<div />").html(pagesArray[i]);
        // add the page with the counter + 1 (first page is 1 not 0)
        $("#flipbook").turn("addPage", element, (i+1));
    }
});

And that's all.

Here is a solution for splitting the content to pages, and than, create a book using turn.js.

The logic of this solution is to check if the next content can be in the current page or we need to create a new page and put the content there.

This code "read" html from a specific div and do the magic ;)

Alse, you can play with the code in jsbin.

var width = 400,
    height = 400,
    padding = 20;

// create a tester div. in this `div` we will put the contents and check if we need a new page
var div = $('<div />').css({
  // divide it by 2 because each page is half from the book
  width: width / 2
}).appendTo(document.body);

var index = 0;
var pages = [];
// get all content from the input html
var contents = $('#text').contents();

while (index < contents.length) {
  var content = contents.eq(index).clone();
  
  div.append(content);
  // check whether the contents exceed the page, if so, remove this content from the page
  if (div.height() > height) {
    content.remove();
    // create a new page
    pages.push(div.clone());
    // reset the tester div's html to check the next content
    div.html('');
  }
  // if this is the last content, push it to a new page and break
  else if (index == contents.length - 1) {
    pages.push(div.clone());
    div.remove();
    break;
  }
  // go to the next content
  else {
    index++;
  }
}

var book = $('#book');
for (var i = 0; i < pages.length; i++) {
  //book.after(pages[i].clone());
  //book.after('<hr />');
  book.append(pages[i]);
}

// init the plugin
book.turn({
  width: width,
  height: height,
  gradients: true, 
  acceleration: true
});

  line-height:1 !important;
  font-size:inherit !important;

It's important to say that this solution is a direction for you. The most chance that you need to add more code to fit this exactly to your need but I did for you the most of the way.
