11,349 Pointsquestion about "this" in each() method
Hi there!
This is the task:
Inside the jQuery each() method, use prepend() to add an '<input type="checkbox"/>' to the beginning of each list item. Use the this keyword, so the callback function doesn't need any arguments.
I tried this:
$('.favorite-things li').each(function() {
this.prepend("<input type='checkbox'/>");
});
It's giving me an error message, and I cannot figure out why.
<!DOCTYPE html>
<html lang="en">
<head>
<title>Document</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<h2>My Favorite Things</h2>
<ul class="favorite-things">
<li>Kittens</li>
<li>Rainbows</li>
<li>Unicorns</li>
<li>Sprinkles</li>
</ul>
<script
src="jquery-3.2.1.min.js"></script>
<script src="app.js"></script>
</body>
</html>
$('.favorite-things li').each(function() {
this.prepend("<input type='checkbox'/>");
});
