了解页面实际重新加载的更好方法是使用大多数现代浏览器支持的导航器对象。

A better way to know that the page is actually reloaded is to use the navigator object that is supported by most modern browsers.

它使用导航时间API 。

//check for Navigation Timing API support
if (window.performance) {
  console.info("window.performance works fine on this browser");
}
  if (performance.navigation.type == 1) {
    console.info( "This page is reloaded" );
  } else {
    console.info( "This page is not reloaded");
  }
