getEntriesByType method
The getEntriesByType()
method returns an array of PerformanceEntry
objects currently present in the performance timeline for a given type.
If you are interested in performance entries of certain name, see Performance.getEntriesByName. For all performance entries, see Performance.getEntries.
Note: This method does not notify you about new performance entries; you will only get entries that are present in the performance timeline at the time you call this method. To receive notifications about entries as they become available, use a PerformanceObserver.
The following entry types are not supported by this method at all and won't be returned even if entries for these types might exist:
"element"
(PerformanceElementTiming
)"event"
(PerformanceEventTiming)"largest-contentful-paint"
(LargestContentfulPaint)"layout-shift"
(LayoutShift
)"longtask"
(PerformanceLongTaskTiming)
To access entries of these types, you must use a PerformanceObserver instead.
Implementation
external PerformanceEntryList getEntriesByType(String type);
