Determining navigation type from PerformanceNavigationTiming

rated 0 times [ 23] [ 6] / answers: 1 / hits: 15829 / 6 Years ago, tue, december 4, 2018, 12:00:00

I used to determine if user had come by clicking the back button in the previous page using window.performance.navigation.type like

if (window.performance.navigation.type === 2) {

    window.location.reload()

}

I saw that this property has been deprecated and succeeded by Navigation Timing Level 2. How can I mimic the behavior of performance.navigation api by this?

I should preface this by saying that I am not JavaScript pro. This is my approach for utilizing Navigation Timing Level 2.

if (String(window.performance.getEntriesByType(navigation)[0].type) === back_forward) {

    window.location.reload()

}

window.performance.getEntriesByType(navigation) returns a list of PerformanceEntry objects every mark set. If you haven't set any marks, this list contains a single object that has the navigation information for the window.
