I'm trying to make the number of nav dots equal number of images in the slider.

HTML: 

<div class="sl-slider">

 <div class="sl-slide bg-1" >
 <div class="sl-slide-inner">
                            <img src="img/1.jpg">

                        </div>
                    </div>

    <div class="sl-slide bg-1">
            <div class="sl-slide-inner">
                            <img src= "img/2.jpg">
                </div>
                    </div>

    <div class="sl-slide bg-1" >
            <div class="sl-slide-inner">
                            <img src="img/3.jpg">

                        </div>
                    </div>

    <div class="sl-slide bg-1" >
            <div class="sl-slide-inner">
                            <img src= "img/4.jpg">
                        </div>
                    </div>


                </div>

<nav id="nav-dots" class="nav-dots">
                    <span class="nav-dot-current"></span>
                    <span></span>
                    <span></span>
                    <span></span>

                </nav>

JS:

<script>

            var count = $(".sl-slider > div").length; 
            while(count){
                $(".nav-dots").append('<span>');
            }
            return false

        </script>

What I'm trying to do is count the number of child elements in the sl-slider and append the number of <span> elements under nav.

Hi, Anthony. In a while clause, it will be evaluated and repeated until the statement inside the parentheses is false. In your case, you have a single number, which means it will evaluate as true infinitely. For this case, I'd personally use a for loop, like this:

for (var i = 0; i < count; i++) {
   $(".nav-dots").append('<span></span>');  //<-- closed your span tag
}
