Question

SUMMARY:

I need to insert a “Back to Top” links after every <div class=”wrapSection”>. I’ve been successful using the following:

<script>
$('.wrapSection').after('
    <div class="backToTop clearfix">
       <a href="#top" class="up">Back To Top </a>
    </div>
 ');
</script>

However, I want to use a smooth scroll when clicking ‘Back to Top.’ With that in mind, I tried the following:

<script>
$('.wrapSection').after('
<div class="backToTop clearfix">
    <a href="javascript:void(0)" onclick="goToByScroll('top')" class="up">
      Back To Top
    </a>
</div>
');
</script>

That does not work. Being a jQuery rookie, I did what seemed logical, which seems to never be the correct answer.

IN A NUTSHELL

More or less, I need this to appear, dynamically, after every <div class=”wrapSection”>:

<div class="backToTop">
    <a class="top" href="javascript:void(0)" onclick="goToByScroll('top')">
        Back to Top
    </a>
</div>

This is the solution I came up with:

​$(document).ready(function() {
    // Markup to add each time - just give the element a class to attach an event to
    var top_html = '<div class="backToTop"><a href="#" class="top">Back To Top</a></div>';
    $(".wrapSection").after(top_html);

    // Use event delegation (see http://api.jquery.com/on/)
    $("body").on("click", ".top", function(e) {
        e.preventDefault();
        $("html,body").animate({ scrollTop: 0 }, "slow");
    });
});​
