iainmcgin / plus_one_rt.js
Created December 11, 2013 16:47
Example of using the W3C Resource Timing API to display the resource timing information of +1 buttons. This code can be pasted into the Javascript console in Chrome on any page.
(function() {
// request PerformanceResourceTiming info for all resources on the page
var resources = window.performance.getEntriesByType('resource');
// filter all resources to just +1 button iframes with timing information
var p1Resources = resources.filter(function(rtInfo) {
return rtInfo.name.indexOf('_/+1/fastbutton') != -1 &&
rtInfo.responseStart != 0;
});
