Answer 1

You can use data() to get the data attributes data-index using the class selector .

Live Demo

$('.phase1').data('index');

You can use descendant selector to find out element with phase class within element with claimed class.

$('.claimed .phase1').data('index');

You can use attr to get the attribute but using the attr will not get you value being changed by javascript. Its worth reading this post for difference between data and attr .

Live Demo

<a id="foo" data-foo="bar" href="#">foo!</a>

alert( $('#foo').attr('data-foo') );
alert( $('#foo').data('foo') );

Answer 2

您还可以使用attr（） jQuery API函数来获取数据属性

$('.phase1').attr('data-index');
