Project Settings: jQuery and Project JavaScript settings in Optimizely Web Experimentation and Optimizely Performance Edge

For a slightly different approach, you can run this code to find the list of functions included in the page's otherwise standard version of jQuery that is not included in the Optimizely Web Experimentation version:

var optimizely_functions = []
for(var f in optimizely.$) {
  optimizely_functions.push("$." + f);
}
l = Object.getPrototypeOf(optimizely.$("body"))
for(var g in l){
  optimizely_functions.push(g);
}
 
var jquery_functions = []
for(var f in $) {
  jquery_functions.push("$." + f);
}
l = Object.getPrototypeOf($("body"))
for(var g in l){
  jquery_functions.push(g);
}
Array.prototype.diff = function(a) {
    return this.filter(function(i) {return a.indexOf(i) < 0;});
};
jquery_functions.diff(optimizely_functions);

Do not include jQuery in project code

Select this option when you want Optimizely Web Experimentation to use the version of jQuery running natively on your page. Make sure that it is loaded before Optimizely Experimentation on the page. Here is an example of how to implement jQuery and the Optimizely Web Experimentation snippet in the head of your page:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script src="//cdn.optimizely.com/js/21882493.js"></script>

Include trimmed jQuery 1.11.3 in project code

This default option contains 196 core methods from jQuery 1.11.3. Search the following list to see whether a given function is included:

"$._data", "$._queueHooks", "$._removeData", "$.acceptData", "$.access", "$.attr", "$.attrHooks", "$.buildFragment", "$.cache", "$.Callbacks", "$.camelCase", "$.cleanData", "$.clone", "$.contains", "$.css", "$.cssHooks", "$.cssNumber", "$.cssProps", "$.data", "$.Deferred", "$.dequeue", "$.dir", "$.each", "$.error", "$.event", "$.Event", "$.expando", "$.expr", "$.extend", "$.filter", "$.find", "$.fn", "$.globalEval", "$.grep", "$.guid", "$.hasData", "$.holdReady", "$.inArray", "$.isArray", "$.isEmptyObject", "$.isFunction", "$.isNumeric", "$.isPlainObject", "$.isReady", "$.isWindow", "$.isXMLDoc", "$.makeArray", "$.map", "$.merge", "$.noConflict", "$.noData", "$.nodeName", "$.noop", "$.now", "$.param", "$.parseHTML", "$.prop", "$.propFix", "$.propHooks", "$.proxy", "$.queue", "$.ready", "$.readyWait", "$.removeAttr", "$.removeData", "$.removeEvent", "$.sibling", "$.style", "$.support", "$.swap", "$.text", "$.trim", "$.type", "$.unique", "$.valHooks", "$.when", "$a", "add", "addBack", "addClass", "after", "append", "appendTo", "attr", "before", "bind", "blur", "change", "children", "clearQueue", "click", "clone", "closest", "constructor", "contents", "contextmenu", "css", "data", "dblclick", "delay", "delegate", "dequeue", "detach", "domManip", "each", "empty", "end", "eq", "error", "extend", "filter", "find", "first", "focus", "focusin", "focusout", "get", "has", "hasClass", "hide", "hover", "html", "index", "init", "insertAfter", "insertBefore", "is", "jquery", "keydown", "keypress", "keyup", "last", "length", "load", "map", "mousedown", "mouseenter", "mouseleave", "mousemove", "mouseout", "mouseover", "mouseup", "next", "nextAll", "nextUntil", "not", "off", "on", "one", "parent", "parents", "parentsUntil", "prepend", "prependTo", "prev", "prevAll", "prevUntil", "promise", "prop", "push", "pushStack", "queue", "ready", "remove", "removeAttr", "removeClass", "removeData", "removeProp", "replaceAll", "replaceWith", "resize", "scroll", "select", "selector", "serialize", "serializeArray", "show", "siblings", "slice", "sort", "splice", "submit", "text", "toArray", "toggle", "toggleClass", "trigger", "triggerHandler", "unbind", "undelegate", "unload", "unwrap", "val", "wrap", "wrapAll", "wrapInner"

Include full jQuery 1.11.3 in project code

If you want to use Optimizely Web Experimentation's jQuery and have access to certain functions not included in the trimmed library (such as "animate" or "ajaxComplete") you might want to include the full library. This setting contains the methods above and 51 more. They are:

"$._evalUrl", "$.active", "$.ajax", "$.ajaxPrefilter", "$.ajaxSettings", "$.ajaxSetup", "$.ajaxTransport", "$.Animation", "$.easing", "$.etag", "$.fx", "$.get", "$.getJSON", "$.getScript", "$.lastModified", "$.offset", "$.parseJSON", "$.parseXML", "$.post", "$.speed", "$.timers", "$.Tween", "ajaxComplete", "ajaxError", "ajaxSend", "ajaxStart", "ajaxStop", "ajaxSuccess", "andSelf", "animate", "fadeIn", "fadeOut", "fadeTo", "fadeToggle", "finish", "height", "innerHeight", "innerWidth", "offset", "offsetParent", "outerHeight", "outerWidth", "position", "scrollLeft", "scrollTop", "size", "slideDown", "slideToggle", "slideUp", "stop", "width"

Include full jQuery 1.6.4 in project code

If you have a legacy project using jQuery 1.6.4, you will see this option. If you want to use Optimizely Web Experimentation's jQuery and have access to certain functions not included in the trimmed library (such as "animate" or "ajaxComplete") you may find it useful to include the full library. This setting contains the methods above and 48 more. They are:

"_toggle", "$.active", "$.ajax", "$.ajaxPrefilter", "$.ajaxSettings", "$.ajaxSetup", "$.ajaxTransport", "$.easing", "$.etag", "$.fx", "$.get", "$.getJSON", "$.getScript", "$.lastModified", "$.offset", "$.param", "$.post", "$.speed", "$.timers", "ajaxComplete", "ajaxError", "ajaxSend", "ajaxStart", "ajaxStop", "ajaxSuccess", "animate", "fadeIn", "fadeOut", "fadeTo", "fadeToggle", "height", "hide", "innerHeight", "innerWidth", "offsetParent", "outerHeight", "outerWidth", "position", "scrollLeft", "scrollTop", "serialize", "serializeArray", "show", "slideDown", "slideToggle", "slideUp", "stop", "width"
