[英]Prevent HTML5 Video native controls from appearing on mouse hover
我在网页中嵌入了HTML5视频。 由于各种原因,我无法访问视频标签本身,尽管可以通过iFrame对其进行访问。 通过JavaScript,我运行了以下代码:
videoElement.removeAttribute('controls');
videoElement.muted = true;
其中“ videoElement”是对视频标签的DOM对象的引用。
视频会静音,这意味着它会响应设置“静音”属性,但是即使将“ controls”属性删除,当鼠标悬停在视频上时,本机控件仍会出现。
谁能发现我在做什么错?
编辑:
这是我正在使用的代码,它使用Kaltura平台,因此可能没有多大意义:
<script src="http://cdnapi.kaltura.com/p/{PARTNER_ID}/sp/{PARTNER_ID}00/embedIframeJs/uiconf_id/{uiConfId}/partner_id/{PARTNER_ID}"></script>
<script>
mw.setConfig('Kaltura.LeadWithHTML5', true);
mw.setConfig('EmbedPlayer.NativeControls', true);
mw.setConfig('EmbedPlayer.EnableRightClick', false);
mw.setConfig('controls', false);
kWidget.embed({
'targetId': 'kaltura_player_0000000000',
'wid': '_000000',
'uiconf_id': '000000',
'entry_id': '1_000000',
'flashvars': {
'controlsHolder.includeInLayout': false,
'controlsHolder.visible': false,
'externalInterfaceDisabled': false,
'loop': false,
'autoPlay': true,
'autoMute': true
},
'params': {
'wmode': 'transparent'
},
readyCallback: function( playerId ){
var kdp = $('#kaltura_player_0000000000_ifp').contents().find('video');
// This is where I attempt to remove the controls attribute:
kdp[0].removeAttribute('controls');
kdp[0].muted = true;
}
});
</script>
然后,这个Kaltura库创建一个iFrame,并为用户的设备/浏览器(无论是HTML5视频,Flash等)填充适当的媒体播放器。缺点是您失去了一定的控制权,并且仅限于Kaltura允许您配置。
更新:
我发现很难发现如何自定义Kaltura Media Player的外观和感觉,花了很长时间阅读文档并进行了实验,但是以下冗长的方法才是我最终如何管理它的方法:
我为Kaltura编写了一个自定义插件,然后将自己的功能放在该插件中:
kWidget.embed({
'targetId': 'kaltura_player_0000000000',
'wid': '_000000',
'uiconf_id': 00000000,
'flashvars': {
'controlsHolder.includeInLayout': false,
'controlsHolder.visible': false,
'externalInterfaceDisabled': false,
'loop': false,
'autoPlay': true,
'autoMute': true,
'IframeCustomPluginCss1' : 'assets/css/custom_styles.css?sid=',
"video-component": {
'plugin': true,
'iframeHTML5Js' : 'assets/js/custom_component.js?sid='
},
readyCallback: function(playerId) {
var kdp = document.getElementById(playerId);
kdp.addJsListener( 'playerStateChange', function(playerState, playerId) {
if (['playing','paused'].indexOf(playerState) > -1) {
// declared in custom_component.js
updateStateButton();
}
}
}
}
});
上面的代码配置了基本播放器,然后插件添加了我的自定义控件并将其绑定到播放器,而自定义css文件隐藏了eplayer附带的控件:
mw.kalturaPluginWrapper(function() {
mw.PluginManager.add( 'video-component', mw.KBaseComponent.extend({
defaultConfig: {
parent: "videoHolder", // the container for the button
order: 41, // the display order ( based on layout )
displayImportance: 'low', // the display importance, determines when the item is removed from DOM
align: "right", // the alignment of the button
cssClass: "kaltura-logo", // the css name of the logo
href: 'http://www.kaltura.com', // the link for the logo
title: 'Kaltura', // title
img: null // image
},
getComponent: function() {
console.log('running custom video component');
if (!this.$el) {
var playPauseBtn = document.createElement('img');
playPauseBtn.setAttribute('id', 'play-pause');
playPauseBtn.setAttribute('src', 'assets/images/pause.png');
var muteButton = document.createElement('img');
muteButton.setAttribute('id', 'video-volume');
muteButton.setAttribute('src', 'assets/images/volume_on.png');
this.$el = document.createElement('div');
this.$el.setAttribute('id', 'custom-video-controls');
this.$el.setAttribute('id', 'custom-video-controls');
this.$el.appendChild(playPauseBtn);
this.$el.appendChild(muteButton);
var videos = document.getElementsByTagName('video');
var video = videos[0];
var togglePlayPauseBtn = function(buttonClicked) {
// player state can be toggled via clicking on the video, or on the play / pause button
// if the play / pause button is clicked it will trigger the 'playerStateChange' event
// which will trigger this function again, the following statements prevent a race condition
if (window.buttonClicked) {
window.buttonClicked = false;
return false;
}
if (buttonClicked) {
window.buttonClicked = true;
}
// togle video state
if (video.paused) {
video.play();
$(playPauseBtn).attr('src', 'assets/images/pause.png');
} else {
video.pause();
$(playPauseBtn).attr('src', 'assets/images/play.png');
}
}
window.parent.updateStateButton = function() {
togglePlayPauseBtn();
}
$(playPauseBtn).on('click', function() {
togglePlayPauseBtn(true);
});
$(muteButton).on('click', function() {
if (!video.muted) {
video.muted = true;
$(muteButton).attr('src', 'assets/images/volume_on.png');
} else {
video.muted = false;
$(muteButton).attr('src', 'assets/images/volume_off.png');
}
});
setTimeout(function() {
$(playPauseBtn).fadeOut('slow');
$(muteButton).fadeOut('slow');
}, 2000);
$('.mwPlayerContainer').on('mousemove', function() {
clearInterval(window.playPauseFadeOut);
$(playPauseBtn).fadeIn(100);
$(muteButton).fadeIn(100);
window.playPauseFadeOut = setTimeout(function() {
$(playPauseBtn).fadeOut('slow');
$(muteButton).fadeOut('slow');
}, 1200);
});
}
return $(this.$el);
}
}) );
});
最后,这是自定义css:
.mwPlayerContainer .playerPoster,
.mwPlayerContainer .largePlayBtn,
.mwPlayerContainer .controlBarContainer,
.mwPlayerContainer .topBarContainer {
display: none !important;
}
.mwPlayerContainer .videoHolder #custom-video-controls {
text-align: center;
}
.mwPlayerContainer .videoHolder #custom-video-controls #play-pause {
position: absolute;
top: 50%;
left: 50%;
margin: -80px 0 0 -80px;
border: 0;
cursor: pointer;
}
.mwPlayerContainer .videoHolder #custom-video-controls #video-volume {
position: absolute;
left: 90%;
top: 50px;
border: 0 !important;
}
请尝试以下操作:
videoElement.controls = false
