我正在使用以下代码在我的页面上嵌入YouTube视频:
<iframe width="400" height="300" id="newvid" src="http://www.youtube.com/embed/url?modestbranding=1&showinfo=0&feature=player_embedded&fs=0&iv_load_policy=3&rel=0" frameborder="0"></iframe>
我正在尝试使用Youtube API,因此一旦用户播放视频就会执行javascript功能,但以下代码无效,因为我在点击视频时看不到任何警告:
<script src="https://www.youtube.com/iframe_api"></script>
<script>
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('newvid', {
events: {
'onStateChange': function(event) {
if (event.data == YT.PlayerState.PLAYING) {
myFunction();
}
}
}
});
}
</script>
<script>
function myFunction() {
alert("I am an alert box!");
}
</script>

应使用div容器设置,而不是选择iFrame。 (这可能无法在代码段容器中正确运行,但请尝试使用代码)。
<div id="newvid"></div>
<script src="https://www.youtube.com/iframe_api"></script>
<script>
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('newvid', {
height: '300',
width: '400',
videoId: 'SwxdBiazu8M', // Example video ID
events: {
'onStateChange': function(event) {
if (event.data == YT.PlayerState.PLAYING) {
myFunction();
}
}
}
});
}
</script>
<script>
function myFunction() {
alert("I am an alert box!");
}
</script>

下面的代码使用JS function
中的enablejsapi
演示并执行iframe
-
<!doctype html>
<html>
<body>
<iframe id="ytplayer" type="text/html" width="640" height="390" src="https://www.youtube.com/embed/YtF6p_w-cSc?autoplay=1&controls=0&enablejsapi=1" frameborder="0"></iframe>
<script>
// Load the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// Replace the 'ytplayer' element with an <iframe> and
// YouTube player after the API code downloads.
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('ytplayer', {
height: '390',
width: '640',
events: {
'onStateChange': function(event) {
if (event.data == YT.PlayerState.PLAYING) {
myFunction();
}
}
}
});
}
function myFunction() {
alert("I am an alert box!");
}
</script>
</body>
</html>
此处JSFiddle
根据上述代码,JS function
为playerstate
后,系统会调用PLAYING
。希望这对你有帮助,你也在寻找同样的东西。另外,如果您有任何问题,请告诉我。
谢谢..!
