Click and Increase the Size of an Image using jQuery
Note that for demonstration purposes, I have included jQuery and CSS code in the same page. Ideally, these resources should be created in separate folders for maintainability.
Let us quickly jump to the solution and see how we can view a larger image when an image is clicked on
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>Click and Increase the Size of an Image</title>
<style type="text/css">
.imgthumb
{
height:100px;
width:100px;
}
.imgdiv
{
background-color:White;
margin-left:auto;
margin-right:auto;
padding:10px;
border:solid 1px #c6cfe1;
height:500px;
width:450px;
}
</style>
<script type="text/javascript"
src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js">
</script>
<script type="text/javascript">
$(function() {
$("img.imgthumb").click(function(e) {
var newImg = '<img src='
+ $(this).attr("src") + '></img>';
$('#ladiv')
.html($(newImg)
.animate({ height: '300', width: '450' }, 1500));
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div class="imgdiv">
<h2>Click on the thumbnail to view a large image</h2>
<br />
<asp:Image ID="imgA" class="imgthumb" runat="server"
ImageUrl="../images/1.jpg" />
<asp:Image ID="imgB" class="imgthumb" runat="server"
ImageUrl="../images/2.jpg" />
<asp:Image ID="imgC" class="imgthumb" runat="server"
ImageUrl="../images/3.jpg" />
<asp:Image ID="Image1" class="imgthumb" runat="server"
ImageUrl="../images/4.jpg" />
<hr /><br />
<div id="ladiv"></div>
</div>
</form>
</body>
</html>
This recipe demonstrates how to increase the size of an image when it is clicked. To give it an Image gallery effect, when a thumbnail is clicked, we create a new image element and set its source, to the source of the clicked thumbnail.
var newImg = '<img src='
+ $(this).attr("src") + '></img>';
The next and final step is to set the html contents of a div element to the ‘newImg’ variable and then increase the image size, by animating the height and width of the image.
$('#ladiv')
.html($(newImg)
.animate({ height: '300', width: '450' }, 1500));
When you run the application, click on the thumbnail to see a large version of the image with animation, as shown below. Additionally, you can also preload the images for better performance.
