问题描述
这是在 angular2+ 中找到页面加载时间的正确方法吗??我不这么认为,这只是路由变化的时间差.如何将页面DOM内容加载时间添加到其中.??
Is this the right way to find page load time in angular2+?? I don't think so, It's just the time difference between the route change.How can we add the page DOM content load time to it.??
this.router.events.subscribe((val) => {
const navigationComplete = val instanceof NavigationEnd;
const navigationStart = val instanceof NavigationStart;
if(navigationStart){
this.navigationStartTime = (new Date).getTime();
}
if (navigationComplete) {
this.currentPage = this.router.url; // Current page route
this.currentLocation = (this.platformLocation as any).location.href; // Current page url
let endTime = (new Date).getTime();
this.pageLoadTime = Number(endTime) - Number(this.navigationStartTime); // Page load time
}
});
推荐答案
你绝对可以使用 chrome 开发工具来分析 @AurA 提到的性能
在上面的所有脚本中你可以单独初始化
you can definitely use chrome dev tools to analyse perfomance as mentioned by @AurA
separately in the above all scripts you can initialise
<script type="text/javascript">
var timerStart = Date.now();
</script>
在主组件中
ngAfterViewInit(){
console.log("Time until reaching run phase: ", Date.now() - $window.timerStart);
}
尚未测试.但应该运行.
Havent tested. But should run.
