requestStart property
double
get
requestStart
The requestStart
read-only property returns a DOMHighResTimeStamp
of the time immediately before the browser starts requesting the resource
from the server, cache, or local resource. If the transport connection
fails and the browser retires the request, the value returned will be the
start of the retry request.
There is no end property for requestStart
. To measure the request
time, calculate PerformanceResourceTiming.responseStart - requestStart
(see the example below).
Implementation
external double get requestStart;
