I am working with the <div id="contact"> element and its associated CSS
#contact {
background: url(../images/icon/contact.png) left top no-repeat;
display: inline-block;
width: 29px;
height: 30px;
}
I need to dynamically add a CSS class to the id contact using JSP.
Below is the snippet of the CSS class I want to add to id=contact dynamically through JSP.
#contact.active {
background: url(../images/icon/active_contact.png) left top no-repeat !important;
}
To easily apply CSS style that is already defined, you can simply add the specified class to your <div id="contact">.
To use JQuery and the addClass() function:
$( "#contact" ).addClass( "active" );
If you prefer plain Javascript:
var element = document.getElementById('contact');
if(element) {
// Check if the div already has another class active
element.className += element.className ? ' active' : 'active';
}
