每当YouTube视频结束播放时，都会重新加载页面（但有时不会）

Question

该代码位于javascript中，我只是在调整它不用于Chrome，因为Chrome现在不支持它。 95％的时间页面被“刷新”，由于某种原因，当您不期望它被卡住时，它会被卡住。因此，为了保持它的重新加载页面，我使用PHP的Youtube API获得了视频时间，并且没有袖手旁观。诀窍是，如果实际上发生“事件”，则变量名dontdo应该更改为true，因此它不会在该时间之后刷新页面，但是由于某种原因，它不会取消重新加载，JAVASCRIPT VARIABLES错了。

var player;

var nosaukums = "randomvideo";


   var dontdo;
    <?php 
        $is_chrome = (stripos($_SERVER['HTTP_USER_AGENT'], 'Chrome') !== false);
    if($is_chrome == 0){
        ?>

有时onYouTubeIframeAPIReady()仍不会发生，或者onPlayerStateChange()上的情况得到错误的结果。我不知道。 GoAway是整个代码的精髓，但是当您不那么期望它时，它仍然会卡住。

对于那些不会阅读PHP的人。 （真的吗？）
