One emoticon preview only once

Question

Textarea cannot preview image so I make it's background and color transparent and a another div set behind it to preview textarea's val.

Now, when I write any emoticon text once more like " :) :) :) " its replace only 1st one. Where is my wrong here please?

Just Suggest me: How many question in a post stockoverflow accept? (Because I have more Question here also.)

var smileys = {
        ':)': '<img src="http://www.html5gamedevs.com/public/style_emoticons/default/wacko.png" border="0" alt="" />',
  ':-)': '<img src="http://www.html5gamedevs.com/public/style_emoticons/default/wacko.png" border="0" alt="" />',
  ':D': '<img src="http://www.html5gamedevs.com/public/style_emoticons/default/wacko.png" border="0" alt="" />',
};

function smilyMe(msg) {
    msg = msg.replace(/(?:\r\n|\r|\n)/g, '<br />');
    for (var key in smileys) {
        msg = msg.replace(key, smileys[key]);
    }
    return msg;
}
$(document).ready(function() {
  $(".chat > textarea").bind("keyup", function(e) {
    $(".chat > div").html(smilyMe($(".chat > textarea").val()));
  });
  $('#maintbox').on('keyup',function() {
    $(this).css('height','auto');
    $(this).css('height',Math.max(this.scrollHeight)+'px');
  });
  $('#showhide_emobox').click(function(){
    $('#emobox').fadeToggle();
    $(this).toggleClass('active');
  });
  $(".embtn").click(function(event){
    var prevMsg = $(".chat > textarea").val();
    var emotiText = $(event.target).attr("alt");
    $(".chat > textarea").html(prevMsg + emotiText);
  });
    $('textarea').elastic();
});

javascript .replace() function replaces only first occurrence, you'll need something like replaceAll().

Take a look at this article

How to replace all occurrences of a string in JavaScript?

You need to build your regular expression with the global search flag g to replace all occurrences.

Also special characters in the key must be escaped.

function escapeRegExp(str) {
  return str.replace(/[\-\[\]\/\{\}\(\)\*\+\?\.\\\^\$\|]/g, "\\$&");
}

function smilyMe(msg) {
    msg = msg.replace(/(?:\r\n|\r|\n)/g, '<br />');
    for (var key in smileys) {
        msg = msg.replace(new RegExp(escapeRegExp(key), "g"), smileys[key]);
    }
    return msg;
}

Thank you sir. I have more problem in my right side emoticon icon toggle. Can I ask here more please? – koc Jan 29 '15 at 17:12
You welcome! This one is already answered, I would recommend you create a new post for each question. You will receive more attention than if you expand this one. It is also easier to get answers to small problems well defined separately instead a big post – Tobías Jan 29 '15 at 17:39
