Here is a JSFiddle

HTML:

<textarea rows="5" id="content_txt" name="TextArea1" runat="server" maxlength="50"></textarea>
<p id="message"></p>

JS:

var area = document.getElementById("content_txt");
var message = document.getElementById("message");
var maxLength = 50;
var checkLength = function() {
    if(area.value.length < maxLength) {
        message.innerHTML = (maxLength-area.value.length) + " characters remaining";
    }
}
setInterval(checkLength, 300);
Answer:2

I have a little but functional solution my friend, try this:

HTML CODE

    <textarea name="message"placeholder="Reply message..." maxlength="155" onkeyup="counter(this);"></textarea>
<div id="counter_div">0/155</div>

JAVASCRIPT CODE

<script>
    function counter(msg){
        document.getElementById('counter_div').innerHTML = msg.value.length+'/155';
    }
</script>

This case limit 155 characters.

Answer:3

this will return current length of the textarea using jquery var length = $('#content_txt').val().length; and rest of the logic you have to give it a try..

Answer:4

try this

  function fix(dis)
    {
      var total=50; // ho many you want to show
      var val = dis.value;

      var count = val.length;
      document.getElementById('remaining').innerHTML= total-count;
    }

    <td valign='top'>
        <textarea rows="5" id="content_txt" name="TextArea1" runat="server" maxlength="50" onkeyup="fix(this)"></textarea>
    </td>

    <p><span id="remaining">0</span> Characters remaining</p>
