data = elem.getAttribute( "data-" + key ); // Line 1606, jQuery.1.5.2.js

<div id="some-data" data-name="Tom"></div>

var el = document.getElementById("some-data");
var name = el.getAttribute("data-name");
alert(name);

    var dataset = {};
    var attrs = node.attributes;
    for (var i = 0; i < attrs.length; i++) {
        var attr = attrs.item(i);
        // make sure it is a data attribute
        if(attr.nodeName.match(new RegExp(/^data-/))) {
            // remove the 'data-' from the string 
            dataset[attr.nodeName.replace(new RegExp('^data-'), '')] = attr.nodeValue;
        }
    }
    return dataset;
