The jQuery focusout() is an inbuilt method that is used to remove focus from the selected element.
Syntax:
$(selector).focusout(function);
Parameter: It accepts a parameter "function" which is to be executed after the execution of the fadeout method.
Example 1: jQuery code to show the working of focusout() method.
<!DOCTYPE html>
<html>
<head>
<script src=
"https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js">
</script>
<!-- jQuery code to show the working of this method -->
<script>
$(document).ready(function () {
$("div").focusin(function () {
$(this).css("background-color", "green");
});
$("div").focusout(function () {
$(this).css("background-color", "#FFFFFF");
});
});
</script>
<style>
div {
border: 2px solid black;
width: 50%;
padding: 20px;
}
input {
padding: 5px;
margin: 10px;
}
</style>
</head>
<body>
<!-- click inside the field focusin will
take place and when click outside
focusout will take place -->
<div>
Enter name:
<input type="text">
<br>
</div>
</body>
</html>
Output:

Example 2: In this example, we will animate the input box by using focusin() and focusout().

$("div").focusin(function () {
$("input").animate({ fontSize: "+=14px" });
});
$("div").focusout(function () {
$("input").animate({ fontSize: "-=14px" });
});
});
