Andy-
I'm trying to use the Navigation Timing package to measure how long a
page takes to be rendered. So that would be loadEventEnd-responseEnd,
however I am finding that loadEventEnd is always 0 for me, even though
I am accessing it from within a window.onload function, e.g:
window.onload = function() {
var t = performance.timing;
var render_time = parseInt(t['loadEventEnd']) - parseInt(t['responseEnd']);
}
What do I have to wait for before loadEventEnd gets set?
Thanks!
