I am creating a Phonegap app that requires the user to select text inside a p element, and then "copy" the text which modifies it to me needs.
There is a problem, however, with selecting text inside the p tag. The text is retrieved from my server where it is outputted like so:
<p style="white-space:pre-wrap">Proin quis tortor orci. Etiam at risus et justo dignissim congue. Donec congue lacinia dui, a porttitor lectus condimentum laoreet. Nunc eu ullamcorper orci. Quisque eget odio ac lectus
vestibulum faucibus eget in metus. In pellentesque faucibus vestibulum. Nulla at nulla justo, eget luctus tortor. Nulla facilisi.
Duis aliquet egestas purus in blandit. Curabitur vulputate, ligula lacinia scelerisque tempor, lacus lacus ornare ante, ac egestas est urna sit amet arcu. Class aptent taciti sociosqu ad litora
</p>
This will alow the text to retain the line breaks without me using <br/> tags, which do not currently work within my Javascript.
Anyways, when you try to select text in this element, the entire p element is selected instead. Here's the transition of what happens when you select a word, then move the bounds to select more text:
NOTE: The text is different in the first sequence because I took the screenshot with different text, but the effect is still the same.
I can't provide a jsFiddle for this as it seems to be only replicated in Phonegap, but I've uploaded my source to test: http://cl.ly/2w0O1d3l3h17
There is no JS in the project, but the HTML and CSS look like this:
HTML:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta name="format-detection" content="telephone=no" />
<meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1"/>
<link rel="stylesheet" type="text/css" href="css/index.css" />
<title>Hello World</title>

What is PDF?
PDF is a portable document format developed by Adobe Systems. PDF
documents are widely used on the Internet, including the this web server, for
several reasons:
q A PDF has the same appearance, colors, fonts, graphics and layout as
the printed document.
PDF files can be viewed in the browser, or saved for off-line use or
printed.
q
The Acrobat Reader software is freely available for most operating
systems.

While the Reader software can't edit (change) a PDF document, it can
copy text from the document and perform word or text-string searches
of the document.

Electronic Fill-In-The-Blank PDF Forms
NOTE: Use of PDF fill-in-the-blank forms does NOT include online
submittal.
Some PDF forms are available in a fill-in-the-blank format. Users now have
the option—on certain OPA forms—to complete the PDF forms
electronically, instead of manually writing or typing the information on a hard
copy version.
The form can be completed in several easy steps.
q The user opens the PDF form in Acrobat Reader—in the browser or as
a standalone product. The user can also save the PDF form to their
computer system and open the form in Acrobat Reader at a later time.
q Once the form is open, the user clicks on the desired field and a

blinking cursor appears.
After the information has been entered in the field, the user can tab to
the next field.
After all the fields have been completed, the user can print out the
page.
NOTE: If the cursor is blinking in a field, the information in that field
will not be printed. Hit "Return" or "Enter" and the information will be
captured for all fields.
Users with Acrobat Reader only, the entered data cannot be saved for later
use.
For those who have the entire Acrobat suite—Acrobat, formerly called
Acrobat Exchange—the data can either be saved separately or as a part of the
form. If you save the data-only, it will take up less disk space and can be
imported back into the same form at any time, provided the form has not
changed. For more information on exporting and importing form data, check
your manual.

Accessibility Tools for Visually Impaired Users
Access.adobe.com provides a set of free tools that allow visually disabled
users to read documents in Adobe PDF format. These tools convert PDF
documents into either HTML or ASCII text, which can then be read by many
screen-reading programs.

CSS:
.text{
white-space:pre-wrap;
word-wrap: break-word;
height:300px;
overflow: scroll;
-webkit-overflow-scrolling: touch;
padding:10px;
border:1px solid #000;
background-color:#fff;
}
One potential solution that I've found is to use contenteditable="true" on the p element, but this has some downfalls:
Another solution I've found is to remove the pre formatting. This, however, removes the line breaks, which I would ideally like to keep.

Your problem is that iOS'es native selection engine selects either separate words or the whole elements. And because you have a single <p> element holding the whole text the native selection engine select the whole <p> element when you try to select more than one line. What you should do is to "hint" the selection engine that you want to be able to select multiple lines. You can achieve that by placing each line of text into a separate block level element, for example <div>.
Here is an example script that parses text inside the <p class="text"> element and puts each line of text into a separate <div> element preserving new lines, empty lines and spaces in the beginning of each line by using non-breaking-space character entity.
var textElm = document.getElementsByClassName("text")[0],
text = textElm.textContent,
html = "";
html = text.replace(/([\t ]*)(.*)\n/g, function(match, spaces, text) {
if (spaces === "" && text === "") spaces = " "; // Make sure empty lines are rendered by adding single to <div>
return "<div>" + Array(spaces.length + 1).join(" ") + text + "</div>"
});
textElm.innerHTML = html;
Then you can also remove white-space:pre-wrap; from the CSS as it is no longer needed.
