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!

Answer 1

Your code works fine, after fixing:

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