This tutorial explains usage of the image selector in JQuery. The image selector selects all the input elements of type image in the document. The images selector represents an image of the document. In this tutorial, we are using image selector with input element and src attribute defines URL of the image to display on the web page. The: image is similar to [type=”image”]. It can be written as colon (:) preceding with image selector.
JQuery Image Selector Syntax
[code lang=”xml”]
$(“:image”)
[/code]
JQuery Image Selector Example
[code lang=”xml”]
<!doctype html>
<head>
<title>JQuery Image Selector</title>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
</head>
<h2>JQuery Image Selector Example</h2>
<script type="text/javascript">
$(document).ready(function(){
$("input:image").css("border", "3px double green");
});
</script>
<body>
<form>
<input type="image" src="https://javabeat.net/wp-content/uploads/2014/03/amazing-300×214.jpg" alt="amazing" width="300" height="214" class="aligncenter size-medium wp-image-15551" />
</form>
</body>
</html>
[/code]
- As shown in the above program, we have used the code inside $(document).ready which is an event which fires up when document is ready. It will run once the page document object model is ready for JavaScript code to execute.
- $(“input:image”).css(“border”, “3px double green”); line defines image selector which selects all the elements of type image. It uses CSS style property which sets two borders with the green color around the image.
