13,783 PointsI need help with Adding/Removing Classes challenge objective 2 of 2. How do I solve this?
The question said that need to chain the appropriate methods to add the disabled to the submit button. I'm actually lost here. Any suggestions?
<!DOCTYPE html>
<html lang="en">
<head>
<title>Document</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<button type="submit" class="submit-btn">Submit If You Can</button>
<script
src="jquery-3.2.1.min.js"></script>
<script src="app.js"></script>
</body>
</html>
const $submit = $('.submit-btn');
$submit.attr('disabled', true);
$submit.attr("disabled",true);
$submit.addClass("disabled")

230,688 PointsWhen you "chain" menthods, you apply one method to the result of another without starting a new statement. For example, if you had two chainable methods working on a single object:
myObject.method1(argA);
myObject.method2(argB);
Then chaining them would look like this:
myObject.method1(argA).method2(argB);
