How to set read more button using data from database in php

Actually I'm using laravel framework.In which I use certain queries and methods to retrieve data from database..

And its my code below

<ul class="booking-list">
    @foreach($aRooms as $aRoom)
        <li>
        ....
            <div class="comment more">
                {{$aRoom->room_desc}}
            </div>
        ....
        </li>
    @endforeach
</ul>

There are many contents to display like {{$aRoom->room_desc}}.But by using this {{$aRoom->room_desc}} I have to set the Read more Read less toggle option.

I don't know how to set that using jQuery,if the data is from database

And here is my jQuery,

<script>
$(document).ready(function() {
    var showChar = 100;
    var ellipsestext = "...";
    var moretext = "More (+)";
    var lesstext = "Less (-)";
    $('.more').each(function() {
        var content = $(this).html();

        if(content.length > showChar) {

            var c = content.substr(0, showChar);
            var h = content.substr(showChar-1, content.length - showChar);

            var html = c + '<span class="moreelipses">'+ellipsestext+'</span>&nbsp;<span class="morecontent"><span>' + h + '</span>&nbsp;&nbsp;<a href="" class="morelink">'+moretext+'</a></span>';

            $(this).html(html);
        }

    });

    $(".morelink").click(function(){
        if($(this).hasClass("less")) {
            $(this).removeClass("less");
            $(this).html(moretext);
        } else {
            $(this).addClass("less");
            $(this).html(lesstext);
        }
        $(this).parent().prev().toggle();
        $(this).prev().toggle();
        return false;
    });
});
</script>
