The mouseout() Event executes when a mouse pointer leaves an element as well as its child element.
<html> <head> <title> My First Programme </title> </head> <body> <h1> JQuery </h1> <p class = "para1"> First Paragraph </p> <img src = "/myImage.png" alt = "Bring the mouse pointer here"/> <script src = "https://cdnjs.cloudflare.com/ajax/libs/JQUERY/3.3.1/jquery.min.js"> </script> <script> $('img').mouseout( function() { $('p').text("Mouse pointer left the image") }); </script> </body> </html>
So, if you look at the above code, we have a <p> element,
<p class = "para1"> First Paragraph </p>
And we have an image,
<img src = "/myImage.png" alt = "Bring the mouse pointer here"/>
Now, if we take a look at the JQuery statement,
$('img').mouseout( function() { $('p').text("Mouse pointer left the image") });
At first we locate the image,
$('img')
Then we use the mouseout() event,
$('img').mouseout(...)
And put the function inside mouseout() event to change the contents of <p> element.
$('img').mouseout( function() { $('p').text("Mouse pointer left the image") });
And the function,
function() { $('p').text("Mouse pointer left the image") }
Changes the content of <p> with the text,
'Mouse pointer left the image'
When the mouse pointer leaves the Image.
Now, let us take another example, where the <img> element is under a <div> element.
<html> <head> <title> My First Programme </title> </head> <body> <h1> JQuery </h1> <p class = "para1"> First Paragraph </p> <div> <img src = "/myImage.png" alt = "Bring the mouse pointer here"/> </div> <script src = "https://cdnjs.cloudflare.com/ajax/libs/JQUERY/3.3.1/jquery.min.js"> </script> <script> $('div').mouseout( function() { $('p').text("Mouse pointer left the image") }); </script> </body> </html>
In this case, we have the <img> element inside a <div> element.
<div> <img src = "/myImage.png" alt = "Bring the mouse pointer here"/> </div>
Now, if you see the JQuery statement,
$('div').mouseout( function() { $('p').text("Mouse pointer left the image") });
We are calling the mouseout() event on the <div> element. And since the <img> element is inside the <div> element, the mouseout() event gets triggered.
