  Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up
  one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum es from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum
  et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", es from a line in section
  1.10.32. The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, acpanied by English

From above code, as I inspected the new <page class='a4'></page> was created but I could not get the exceed content and put them in a new created page.

How can I do to get new page filled with exceed content from previous page?

• javascript
• html
• css

• 1 Were do you want to split? At a whole sentence or word or at the exact overflowing character? – Jonas Wilms Commented Feb 11, 2018 at 16:40
• This similar answer might be helpful – Jonas Wilms Commented Feb 11, 2018 at 16:42
• @JonasW. I would like to split at the exact overflowing character, this would create two or more pages to house the exceed content. Thanks. – Houy Narun Commented Feb 11, 2018 at 16:42
• @JonasW. from answer in link above is say how to get just only once overflow word while hide the rest of overflow, it is not exactly apply to my case. Thanks. – Houy Narun Commented Feb 11, 2018 at 17:54
• Aside: Contrary to popular belief, Lorem Ipsum is not simply random text. Which people actually believe it's random text? I always knew it came from a classic Roman script. – Patrick Roberts Commented Feb 13, 2018 at 19:54

Preamble

I looked at other answers I've found on the internet. However, after implementing them, I could notice that it takes some seconds, not just milliseconds but real seconds, until the script is finished. Meanwhile, the whole GUI of the page is blocked. Therefore, I created my own solution which has a performance of 10ms per page (at least on my puter).

The Idea

We are facing the problem that we do not necessarily have a monospace font, so we cannot calculate the text based on line-height. We need to take a different approach. So I decided to try a method which you can find on various websites if google how to get the number of visible characters. The idea is to write all the letters into a string. Then, in a loop, you create an element, e.g. a span, and add it to the container. You calculate the offsetTop of this span and if it is larger than the offsetHeight of the wrapper, the end of the container is reached. Hence, you only need to count how many span-elements you have got in the container to determine the maximum number of characters which fit into the container.

Usually, the span-element consists of only one character which is a very slow solution. That is why I decided to do it differently: I start by adding 800 characters to the span-element until these blocks do not fit anymore. Then, I add only 800 / 4 = 200 characters (in my tests these were the best values for your container concerning the performance) to the span-elements and fill the container again. I continue decreasing the character amount of a span-element until it equals one.

This is my function to determine the number of visible characters:

function countVisibleChars(elem, text) {
  var visibleChars = 0;
  for (var charNum = 800; charNum > 0; charNum = Math.floor(charNum / 4)) {
    for (var i = visibleChars; i < text.length; i += charNum) {
      var tempSpan = document.createElement('span');
      tempSpan.innerText = text.substring(i, i + charNum);
      elem.appendChild(tempSpan);
      visibleChars += charNum;
      if (tempSpan.offsetTop >= elem.offsetHeight) {
        elem.removeChild(elem.lastChild);
        elem.removeChild(elem.lastChild);
        visibleChars -= 2 * charNum;
        break;
      }
    }
  }

  return visibleChars;
}

Use of this function

To use this function properly for your needs, you have to call it multiple times until all characters are assigned to a page-element. You should use a loop like this:

var initialPage = document.getElementsByClassName('a4')[0];
var text = initialPage.innerText;
var charSumInitialPage = countVisibleChars(initialPage, text);
var charSum = charSumInitialPage;

while (charSum < text.length) {
  var newPage = document.createElement('page');
  initialPage.innerText = '';
  var chars = countVisibleChars(initialPage, text.substring(charSum));
  charSum += chars;
  newPage.innerText = text.substring(charSum - chars, charSum);
  document.body.appendChild(newPage);
}

Note that you cannot use the created elements to calculate the maximum number of characters. Always use the initial page-element.

Conclusion

By using this approach, we can create the right number of pages and assign the characters to them without having to wait for a longer time period. Here is an example to illustrate that it works:

window.addEventListener('load', function() {
  var initialPage = document.getElementsByClassName('a4')[0];
  var pageNumber = 1;
  var text = initialPage.innerText;

  var charSumInitialPage = countVisibleChars(initialPage, text);
  var charSum = charSumInitialPage;

  while (charSum < text.length) {
    ++pageNumber;
    var newPage = document.createElement('page');
    newPage.setAttribute('size', 'A4');
    newPage.setAttribute('class', 'a4');
    newPage.dataset.pages = pageNumber;
    initialPage.innerText = '';
    var chars = countVisibleChars(initialPage, text.substring(charSum));
    charSum += chars;
    newPage.innerText = text.substring(charSum - chars, charSum);
    document.body.appendChild(newPage);
  }

  initialPage.innerText = text.substring(0, charSumInitialPage);
}, false);

function countVisibleChars(elem, text) {
  var visibleChars = 0;
  for (var charNum = 800; charNum > 0; charNum = Math.floor(charNum / 4)) {
    for (var i = visibleChars; i < text.length; i += charNum) {
      var tempSpan = document.createElement('span');
      tempSpan.innerText = text.substring(i, i + charNum);
      elem.appendChild(tempSpan);
      visibleChars += charNum;
      if (tempSpan.offsetTop >= elem.offsetHeight) {
        elem.removeChild(elem.lastChild);
        elem.removeChild(elem.lastChild);
        visibleChars -= 2 * charNum;
        break;
      }
    }
  }

  return visibleChars;

If you use Summer Note or similar type of html editor, we can eliminate the idea of having text nodes in your html, because these editors normally wrap everything within <p> tags. For example if you write the following

This is First Line
This is Second Line
This is Third Line

The editor will generate HTML like this.

<p>This is First Line</p>
<p>This is Second Line</p>
<p>This is Third Line</p>

The generated HTML can also have Tables, Lists and may be Images,

<h2>A Title</h2>
<p>A 2-3 line paragraph</p>
<hr><!-- just to prettify -->
<table>...</table>
<ul><li>An Un-ordered List</li></ul>
<ol><li>An Un-ordered List</li></ol>
<p><img src="#" alt="An Image"></p>

There is no way we can split them into pages without any trade-offs. So if we are okay with some trade-offs we can get this done. One good thing about these HTML Editors is that they tend to generate mostly Block level Elements as direct child to the page. So by calculating the position and height of each Block element child we can check if the child fits into the page with simple algorihtm or move it to the next page if it doesn't.

function arrangePage($pageElement, index) {
  if (!index) index = 1;
  var pageHeight = $pageElement.height();
  var children = $pageElement.children();
  for (var i = 0; i < children.length; i++) {
    var child = children.eq(i);
    if(i == 0 && child.height() > pageHeight) continue; /* Infinite loop fix :: explained in answer*/
    var bottom = child.height() + child[0].offsetTop;
    if (bottom < pageHeight) continue;
    var newPage = $('<page size="A4">').appendTo('body').append(children.splice(i));
    arrangePage(newPage, index + 1);
  }
  $('<span>').addClass('page-number').html('Page ' + index).appendTo($pageElement); /* Inerts Page Index*/
}

  arrangePage($("page"));

Well you have to know your line-height and font-size, then you can know lines per height and chars per line. Then it's easy to calculate maximum amount of characters for a page, take a 20 chars buffer (probably not necessary) and cut everything after. That's very easy to calculate when all chars and fonts are the same heights and sizes. And bees very plicated when they're not.

It's easier to work with a span or a div than with a text node if you want to get some sense of position of your text. What you could do is put the text in a span and then you can pare the offsets and know more about the layout.

Once you have this done, if the format and content are variable, you're pretty much stuck with modifying the content and checking as you go to see if it meets your criteria.

For example you could transfer the text letter by letter to a new page and see after each letter if the layout is ok. Like this:

var element = document.getElementsByClassName('a4')[0];

// put your text in a span
var newSpan = document.createElement('span');

<page size="A4" class="a4">Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum es from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", es from a line in section 1.10.32. The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, acpanied by English versions from the 1914 translation by H. Rackham.
