[ad_1] You can give it a callback function that will have the this scoped. $(‘div’).html(function(){ return $(this).data(‘test’); }); <script src=”https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js”></script> <div data-test=”test”></div> <div data-test=”secondary test”></div> Or, seriously, just use a variable (if there is only one). var $div = $(‘#element’); $div.html($div.data(‘test’)); <script src=”https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js”></script> <div id=”element” data-test=”test”></div> 3 [ad_2] solved this in chained jquery functions
[ad_1] Calculate the cumulative sum of the array and store it in another one, that is to say, accumulated[i] = sum of numbers of the array up to ith index. This can be computed in O(n).
