Resizing Header On Scroll Angular
<p>My question is about AngularJS, in response to events (scroll) . I need to change the size of the header on scroll down or resize on scroll up. The code in javascript is next, but I need to implement it in AngularJs:</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>function init() {
    window.addEventListener('scroll', function(e){
        var distanceY = window.pageYOffset || document.documentElement.scrollTop,
            shrinkOn = 300,
            header = document.querySelector("header");
        if (distanceY &gt; shrinkOn) {
            classie.add(header,"smaller");
        } else {
            if (classie.has(header,"smaller")) {
                classie.remove(header,"smaller");
            }
        }
    });
}
window.onload = init();</code></pre>
