representing the number of redirects since the last non-redirect navigation under the current browsing context.
This property is Read only .
perfEntry.redirectCount;
A number representing the number of redirects since the last non-redirect navigation under the current browsing context.
The following example illustrates this property's usage.
function print_nav_timing_data() { // Use getEntriesByType() to just get the "navigation" events var perfEntries = performance.getEntriesByType("navigation"); for (var i=0; i < perfEntries.length; i++) { console.log("= Navigation entry[" + i + "]"); var p = perfEntries[i]; // dom Properties console.log("DOM content loaded = " + (p.domContentLoadedEventEnd - p.domContentLoadedEventStart)); console.log("DOM complete = " + p.domComplete); console.log("DOM interactive = " + p.interactive); // document load and unload time console.log("document load = " + (p.loadEventEnd - p.loadEventStart)); console.log("document unload = " + (p.unloadEventEnd - p.unloadEventStart)); // other properties console.log("type = " + p.type); console.log("redirectCount = " + p.redirectCount); } }
