【问题描述】:
我尝试将以下getting started HTML code 简单地分配给WebBrowser 控件的DocumentText 属性。
<!DOCTYPE html>
<html>
<body>
<!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
<div id="player"></div>
<script>
// 2. This code loads 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);
// 3. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'M7lc1UVf-VE',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.playVideo();
}
// 5. The API calls this function when the player's state changes.
// The function indicates that when playing a video (state=1),
// the player should play for six seconds and then stop.
var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING && !done) {
setTimeout(stopVideo, 6000);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}
</script>
</body>
</html>
这在运行时给了我以下脚本错误:
事实证明,即使是以下简化代码也会产生相同的错误:
webBrowser1.DocumentText = "<!DOCTYPE html><html><body><script src='https://www.youtube.com/iframe_api'></script></body></html>";
所以看起来WebBrowser 控件无法加载 iframe-API。这里可能是什么问题?或者我该如何进一步调查此错误?
【问题讨论】:
-
你能解决你的问题吗?我和你有同样的问题。
-
不,我无法让它与
WebBrowser控件一起使用。我现在改用 Gecko 引擎(Geckofx45 Nuget 包)。
