Question

I’m sure I’m just having a brain fart and I’m missing something obvious, but please help.

I can’t figure out why the following code (the early coding of a custom slide show) is not ruining when the document loads.

$(document).ready(function() {

    var numSlides = $('#slides .slide').length();
    var wrapperWidth = $('#homeBanner').width();
    var totalWidth = numSlides * wrapperWidth;

    // set width of #slides to width of all .slide elements added together
    $('#slides').css('width', totalWidth+'px');

}); // end document.ready()

Answer 1

Length is a property, not a method.

var numSlides = $('#slides .slide').length; // note, no parens
