There are times when we need to associate data with the DOM element say td, li, div etc. I used to sometimes provide attribute ‘rel’ to html tag, then access it using $(‘divId’).attr(‘rel’). This worked when we want to associate only one property, but doesn’t work so well when there are multiple properties to be associated with the same element. And I personally never liked this approach as there was no name given to the type of data attached.<\/p>\n

Recently I found that jQuery provides a method called data()<\/a>, which can be used to associate multiple data with the same element. Lets take a look at the example given below :<\/p>\n

[js]
\n<div id=’studentDetail’ data-age=’24’ data-name=’amit’>
\n……
\n<\/div><\/p>\n

<script type="text\/javascript"><\/p>\n

$(‘#studentDetail’).data(‘age’) \/\/ output : 24
\n $(‘#studentDetail’).data(‘name’) \/\/ output : amit<\/p>\n

$(‘#studentDetail’).data(‘course’, ‘MCA’) \/\/ Associate new data to the element
\n $(‘#studentDetail’).data(‘course’) \/\/ output : MCA<\/p>\n

$(‘#studentDetail’).data(‘course-duration’, ‘3 Years’) \/\/ Associate new data to the element
\n $(‘#studentDetail’).data(‘course-duration’) \/\/ output : 3 Years
\n<\/script><\/p>\n

[\/js]<\/p>\n
