The jQuery hover() method is used to trigger both the mouseenter and mouseleave events, to execute two functions, i.e., when the mouse pointer roams over the selected element.
Syntax:
$(selector).hover(inFunction,outFunction)
In Function:
- It is a mandatory parameter.
- This parameter specifies the function to run when the mouseenter event occurs.
Out Function:
- It is a mandatory parameter.
- This parameter specifies the function to run when the mouseleave event occurs.
Example1:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("p").hover(function(){
$(this).css("background-color", "red");
}, function(){
$(this).css("background-color", "orange");
});
});
</script>
</head>
<body>
<p>Hover the mouse pointer on me and I will change my color!</p>
</body>
