You can do this using dataset property of the element, using with or without jquery it work... i'm not aware of old browser Note: that when you use dash ('-') sign, you need to use capital case. Eg. a-b => aB

_x000D_

function onContentLoad() {_x000D_
  var item = document.getElementById("id1");_x000D_
  var x = item.dataset.x;_x000D_
  var data = item.dataset.myData;_x000D_
_x000D_
  var resX = document.getElementById("resX");_x000D_
  var resData = document.getElementById("resData");_x000D_
_x000D_
  resX.innerText = x;_x000D_
  resData.innerText = data;_x000D_
_x000D_
  console.log(x);_x000D_
  console.log(data);_x000D_
}

_x000D_

<body onload="onContentLoad()">_x000D_
  <div id="id1" data-x="a" data-my-data="b"></div>_x000D_
_x000D_
  Read 'x':_x000D_
  <label id="resX"></label>_x000D_
  <br/>Read 'my-data':_x000D_
  <label id="resData"></label>_x000D_
</body>

You just can use doStuff  event  in your markup and get the data-attribute values via  currentTarget getAttribute  data-id    in angular  HTML    lt div ng-controller  TestCtrl  gt       lt button data-id  345  ng-click  doStuff  event   gt Button lt  button gt   lt  div gt    JS   var app   angular module  app        app controller  TestCtrl   function   scope         scope doStuff   function  item            console log item currentTarget           console log item currentTarget getAttribute  data-id                  Forked your initial jsfiddle  http   jsfiddle net 9mmd1zht 116

Since you are sending the target element to your function  you could do this to get the id   function doStuff item       var id   item attributes  data-id   value     345

the  data   method is from jQuery  If you want to use this method you need to include the jQuery library and access the method like this   function doStuff item      var id     item  data  id        I also updated your jsFiffle  UPDATE  with pure angularjs and the jqlite you can achieve the goal like this   function doStuff item      var id   angular element item  data  id        You must not access the element with    because then you get the pure DOM element without all the jQuery or jqlite extra methods
