У меня есть ссылка на ответ здесь Выберите целое слово с помощью getSelection . Я хотел бы сделать выбор mouseup completed words из body. чем обернуть <p> тег для selection words. Вот код Так как же? Спасибо.

<script src="jquery.js"></script>
<script>
(function($) {
function getSelected() {
  if(window.getSelection) { return window.getSelection(); }
  else if(document.getSelection) { return document.getSelection(); }
  else {
    var selection = document.selection && document.selection.createRange();
    if(selection.text) { return selection.text; }
    return false;
  }
  return false;
}

function expand(range) {
    if (range.collapsed) {
        return;
    }

    while (range.toString()[0].match(/\w/)) {
        range.setStart(range.startContainer, range.startOffset - 1);   
    }

    while (range.toString()[range.toString().length - 1].match(/\w/)) {
        range.setEnd(range.endContainer, range.endOffset + 1);
    }
}

$(document).ready(function() {
  $('body').mouseup(function() {
    var selectionRange = getSelected().getRangeAt(0);
    var start = selectionRange.startOffset; 
    expand(selectionRange);
    var selection = selectionRange.toString();
    if(selection && (selection = new String(selection).replace(/^\s+|\s+$/g,''))) {
        //how to wrap <p> tag for the selection words?
    }
  });
});
})(jQuery);
</script>
<style>
p {color:blue; }
</style>
<body>
Facebook needs to scrape your page to know how to display it around the site.

Facebook scrapes your page every 24 hours to ensure the properties are up to date. The page is also scraped when an admin for the Open Graph page clicks the Like button and when the URL is entered into the Facebook URL Linter. Facebook observes cache headers on your URLs - it will look at "Expires" and "Cache-Control" in order of preference. However, even if you specify a longer time, Facebook will scrape your page every 24 hours.

The user agent of the scraper is: "facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)"
</body>

UPDATE:

var new_html = $('body').html().split(selection, 1)[0] + '<p>' + selection + '</p>' + $('body').html().split(selection, 2)[1];
$('body').html(new_html);

Попробуйте это:

(function($) {
function getSelected() {
  if(window.getSelection) { return window.getSelection(); }
  else if(document.getSelection) { return document.getSelection(); }
  else {
    var selection = document.selection && document.selection.createRange();
    if(selection.text) { return selection.text; }
    return false;
  }
  return false;
}

function expand(range) {
    if (range.collapsed) {
        return;
    }

    while (range.toString()[0].match(/\w/)) {
        range.setStart(range.startContainer, range.startOffset - 1);   
    }

    while (range.toString()[range.toString().length - 1].match(/\w/)) {
        range.setEnd(range.endContainer, range.endOffset + 1);
    }
}

$(document).ready(function() {
  $('body').mouseup(function() {
    var selectionRange = getSelected().getRangeAt(0);
    var start = selectionRange.startOffset; 
    expand(selectionRange);
    var selection = selectionRange.toString();
    if(selection && (selection = new String(selection).replace(/^\s+|\s+$/g,''))) {
        var el = $('body');
        el.html(el.html().replace(selection, "<p>"+selection+"</p>"));    }
  });
});
})(jQuery);
