How to add a variable in javascript function

Question

Pretty sure its a duplicate but I dont find any answer in other post "relative" plus I'm pretty new to Js so dont be too harsh pls :/

I'm creating a simple function in Js/jQuery for resuming too long text. I've done it; it works but now I want to use it with a variable (the number of characters) I specifically set when I call it.

Something like resume(30) while mean if the text is higher than 30 characters resume it after them.

Here Is what I've got so far : ( You can change nbChar by a value )

var nbChar;
function resume(nbChar) {
    $('.resume').each(function () {
        var text = $(this).text();
        if (text.length > nbChar) {
            var less = text.slice(0, nbChar) + '<span class="showMore">...</span>';
            $(this).html(less);

            $(this).data('content', text + '<br/><br/><span class="showLess"> Cacher</span>')
            $(this).data('less', less)
        }
    });
});

Here is a Fiddle if this could help you answer me.

Any help would be gladly accepted, thank you!

Your code works fine, after fixing:

<div class=".resume"> should be <div class="resume">
Line 22 }); should be }
include jQuery library in jsfiddle
