Jquery | attr | Get HTML attribute's value
You can get the value of an attribute for the first element in the set of matched elements using the .attr() function.

$(selector).attr(attribute)
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
var image_height = $("img").attr("height");
alert(image_height);
});
});
</script>
</head>
<body>
<img src="image.jpg" alt="Pulpit Rock" width="284" height="213"><br>
<button>Get the attribute height value</button>
</body>
</html>
