Question

我对js很新，显然不知道我在做什么，但我非常沮丧，非常感谢任何帮助，这就是我正在做的事情：

var pop;

var intermission = {
   ogg: "https://ia802300.us.archive.org/24/items/DriveInIntermission13/Drive-inIntermission13.ogv",
   mp4: "https://ia802300.us.archive.org/24/items/DriveInIntermission13/Drive-inIntermission13_512kb.mp4"
};

var vid; 

document.addEventListener("DOMContentLoaded", function (event) {
   vid = document.querySelector('#tehvidya'); //this is a dom object;

   pop = Popcorn('#tehvidya', {
       frameAnimation: true
   }); 
}



  pop.on()
 "loadedmetadata",
function() {
   pop.play();

   //video has loaded, we now have duration and other metadata
   console.log(pop.duration());
   h1.style.opacity = 0;
});

h1.addEventListener("transitionend", function () {
pop.play();
</script>

Answer 1

您似乎遇到问题：

  pop.on()
 "loadedmetadata",
function() {
   pop.play();

   //video has loaded, we now have duration and other metadata
   console.log(pop.duration());
   h1.style.opacity = 0;
});

我怀疑这应该是：

pop.on("loadedmetadata",function() {
   pop.play();

   //video has loaded, we now have duration and other metadata
   console.log(pop.duration());
   h1.style.opacity = 0;
});

你有一些无关紧要的)搞砸了。

另外，在此：

h1.addEventListener("transitionend", function () {
pop.play();
</script>

你在});之前错过了</script> ......可能还有其他事情，但你肯定错过了接近该函数表达式。
