Print value of textarea using javascript



We are facing the problem to print the full textarea text when using the default browser print. It will print the full content of the pages which will print only that text which is visible to the textarea.


Content which is not displaying or go out of page due to overflow. Please use below code to see that.

We are having the Textarea and div control and when we click on the print then it will hide the text area and put the Textarea text to div


<textarea name="textarea" wrap="wrap" id="the_textarea">
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla tincidunt congue cursus. Nunc nibh augue, bibendum et interdum sed, gravida sit amet nisi. Pellentesque lacinia leo ut nibh pretium sed dapibus
tellus varius. In sit amet turpis purus. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Praesent lacinia odio ut tellus elementum ut lacinia lectus aliquam.
Etiam fringilla velit nec ligula elementum tincidunt. Sed eu neque a odio scelerisque ullamcorper id sed lorem. Sed non leo arcu. Aliquam id metus tellus, pharetra scelerisque tortor. Quisque tellus lorem,
rutrum a suscipit at, vestibulum nec eros. Nulla fringilla hendrerit orci, non molestie eros mollis nec. Proin porttitor, velit eget hendrerit sollicitudin, quam leo dictum sapien, sed tincidunt eros ante ut augue.
Praesent id nisl non risus mattis interdum vitae in ligula. Vivamus porta tellus a felis egestas eu eleifend nisi posuere. Vivamus pharetra fringilla pulvinar. Suspendisse eget ante vel dolor porttitor euismod.
Integer sodales urna eget nisi porttitor sodales. Nullam laoreet lectus id sem tempus bibendum.
Last line of textarea
</textarea>

<div id="print_helper"></div>

Code which will copy the text from textarea to div will be as below

jQuery(function($){
  function copy_to_print_helper(){
    $('#print_helper').text($('#the_textarea').val());
  }

  $('#the_textarea').bind('keydown keyup keypress cut copy past blur change', function(){
    copy_to_print_helper();
  });
  copy_to_print_helper();
});

Code for printing the text by getting all the text of text  area.
$(function() {
var buttons     = $('button');
var printStyle  = $('#print');
var style;

  buttons.click(function() {

    style = 'p { color: ' + $(this).attr('class') + '};';
    printStyle.text(style);
    window.print();

  });

});

We are full code for printing the full text of textarea content into print as below.
<!DOCTYPE html>

<head>
    <meta charset=utf-8 />
    <title>Printing of text area</title>
