Embed your code in a function assigned to the 'onload' event of 'window' object (or in the 'onload' attribute of <body> element -- that's the same event), to the 'DOMContentLoaded' event of 'document' object, or even in a <script> element after the element you want to access with Javascript, to be sure that this element exists when your script run ;) Anyway, the 'DOMContentLoaded' event can only be registered for listening through the .addEventListener() method (or .attachEvent() method for oldest browsers versions): http://www.javascripter.net/faq/addeventlistenerattachevent.htm document.addEventListener('load', function() { var a = document.getElementById("box").innerText; console.log(a); });

You need to make sure the DOM is ready. Wrap your code in an onload function: window.onload = function() { var a = document.getElementById("box").innerText; console.log(a); };
