(just answer the question) Preparation code Preparation code HTML (this will be inserted in the <body> of a valid HTML5 document in standards mode) (useful when testing DOM operations or including libraries) <script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script> <pre id="text" style="height : 200px;"> </pre> Include JavaScript libraries as follows: <script src="//cdn.ext/library.js"></script> Define setup for all tests (variables, functions, arrays or other objects that will be used in the tests) (runs before each clocked test loop, outside of the timed code region) (e.g. define local test variables, reset global variables, clear canvas, etc.) (see FAQ) var ele = document.getElementById("text"); var tenElsStr = "<b>1</b><i>2</i><b>3</b><i>4</i><b>5</b><i>6</i><b>7</b><i>8</i><b>9</b><i> </i>"; function multiply (str, num) { return Array(num + 1).join(str); } // This is much faster than simple use of innerHTML in some browsers // See <http://blog.stevenlevithan.com/archives/faster-than-innerhtml> function replaceHtml(el, html) { var oldEl = el; /*@cc_on // Pure innerHTML is slightly faster in IE oldEl.innerHTML = html; return oldEl; @*/ var newEl = oldEl.cloneNode(false); newEl.innerHTML = html; oldEl.parentNode.replaceChild(newEl, oldEl); /* Since we just removed the old element from the DOM, return a reference to the new element, which can be used to restore variable references. */ return newEl; } var testStr = multiply(tenElsStr, 1000); var $ele = $(ele); Define teardown for all tests (runs after each clocked test loop, outside of the timed code region) (see FAQ) Code snippets to compare Test 1 Title Async (check if this is an asynchronous test) Code ele.innerHTML = testStr Test 2 Title Async (check if this is an asynchronous test) Code ele = replaceHtml(ele, testStr); Test 3 Title Async (check if this is an asynchronous test) Code $ele.html(testStr)
