jQuery: Find all inputs that are descendants of a form and mark them with a dotted red border
jQuery Fundamental - II : Exercise-77
Find all inputs that are descendants of a form and mark them with a dotted red border. Give a green background to inputs that are descendants of a fieldset that is a descendant of a form.
Note: Descendant Selector (“ancestor descendant”) selects all elements that are descendants of a given ancestor. A descendant of an element could be a child, grandchild, great-grandchild, and so on, of that element.
Sample solution :
HTML Code :
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-git.js"></script>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>Find all inputs that are descendants of a form and mark them with a dotted red border. </title>
</head>
<body>
<form>
<label for="name">Child of form:</label>
<input name="name" id="name">
<fieldset>
<label for="newsletter">Grandchild of form, child of fieldset:</label>
<input name="newsletter" id="newsletter">
</fieldset>
</form>
Sibling to form: <input name="none">
</body>
</html>
CSS Code :
form {
border: 2px blue solid;
padding: 2px;
margin: 0;
background: #efe;
}
div {
color: red;
}
fieldset {
margin: 1px;
padding: 3px;
}
JavaScript Code :
$( "form input" ).css( "border", "2px dotted red" );
$( "form fieldset input" ).css( "backgroundColor", "green" );
