Hi i check it in js fiddle but it work fine for me

Working example

Are you use the developing tools for this ? your code is working...

Error script in another place can make you code stopped working. Try to check your syntax

From the code you've provided, there is no group_coment class in your HTML.

Either:

• add class="group_coment" to your textarea element, or
• change the jQuery selector; replace .group_coment with #coment_group_value

Or, if this is the only textarea element on the page, you could replace .group_coment with textarea.

There is no group_coment class in your HTML. Either provide a class in HTMl or write this code for check the value of the textarea.

`$(document).ready(function (){

    var coment_val = $('#coment_group_value').val();
    alert(coment_val);

});`
