<a class="like" onClick="reply_click(this.id)" style=" cursor: pointer; " id="99999999999999">click here.</a>

Actually you are doing it wrong, you are supposed to define document ready function like this

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

and then you are not supposed to pass any value or give to html onclick attribute with any function call, since jQuery itself is enough to do this job for you. See my code below:

<script>
    $(document).ready(function(){
        $('body').on('click','.like',function(){    
            var pro_id = $(this).attr('id');        
            var postData = 'pro_id='+pro_id;
            $.ajax({        
                type: "POST",
                url: "receiver.php",
                data: postData,
                cache: false,
                success: function(){            
                    $('#'+pro_id).html('OK').addClass('unlike').removeClass('like');
                }       
            });
        })
    });
</script>

Your HTML can be like this

<a class="like" style="cursor: pointer;" id="99999999999999">Click here</a>
