Option on jQuery

var heigthList = []; $('query').slice(0, 15).each(function(i) { heigthList.push($(this).height()); });

Option on Vanilla JS

 var heigthList = []; var elements = document.querySelectorAll('query') Array.prototype.slice.call(elements, 0, 15).forEach(function(element) { heigthList.push(element.offsetHeight); })
