如何禁用默认视频控件并显示自定义搜索栏

Question

我在这里处理视频，我想使用 jquery 隐藏默认视频控件并显示我的自定义搜索栏。我试图喜欢这个controls=false但是如果我禁用此功能，我的自定义栏也会禁用。我想穿鞋自定义栏和播放按钮。我不想使用任何插件。 谁能建议我正确的方法？

var vid = document.getElementById("video");
vid.ontimeupdate = function(){
var percentage = ( vid.currentTime / vid.duration ) * 100;
$("#custom-seekbar span").css("width", percentage+"%");
};
$("#custom-seekbar").on("click", function(e){
var offset = $(this).offset();
var left = (e.pageX - offset.left);
var totalWidth = $("#custom-seekbar").width();
var percentage = ( left / totalWidth );
var vidTime = vid.duration * percentage;
vid.currentTime = vidTime;
});//click()

#custom-seekbar
{  
cursor: pointer;
height: 10px;
margin-bottom: 10px;
outline: thin solid orange;
overflow: hidden;
position: relative;
width: 400px;
}
#custom-seekbar span
{
background-color: orange;
position: absolute;
top: 0;
left: 0;
height: 10px;
width: 0px;
}
/* following rule is for hiding Stack Overflow's console  */
.as-console-wrapper{ display: none !important;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<div id="custom-seekbar">
<span></span>
</div>
<video id="video" width="400" controls autoplay>
<source src="http://www.w3schools.com/html/mov_bbb.mp4" type="video/mp4">
</video>

发生此错误的原因是您尚未在常规部分中定义percentage变量。请参阅下面的代码片段：

var percentage = 0;
video.ontimeupdate = function(){
percentage = ( video.currentTime / video.duration ) * 100;
$( '#custom-seekbar span' ).css( 'width', percentage + '%' )
}
$( '#custom-seekbar' ).on( 'click', function( e ){
var offset = $( this ).offset(),
left = ( e.pageX - offset.left ),
totalWidth = $( '#custom-seekbar' ).width(),
percentage = ( left / totalWidth );
video.currentTime = video.duration * percentage;
})

#custom-seekbar {
cursor: pointer;
width: 400px;
height: 10px;
margin-bottom: 5px;
border: thin solid orange;
overflow: hidden;
position: relative;
border-radius: 5px
}
#custom-seekbar span {
background-color: orange;
position: absolute;
top: 0;
left: 0;
height: 10px;
width: 0;
transition-duration: 0.2s
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="custom-seekbar">
<span></span>
</div>
<video id="video" width="400" autoplay>
<source src="http://www.w3schools.com/html/mov_bbb.mp4" type="video/mp4">
</video>

更新：添加播放，暂停和重复按钮。

var percentage = 0;
video.ontimeupdate = function(){
percentage = ( video.currentTime / video.duration ) * 100;
$( '#custom-seekbar span' ).css( 'width', percentage + '%' );
if ( percentage >= 100 ) $( '#play_button' ).html( '⥀' ) /* Repeat */
}
$( '#custom-seekbar' ).on( 'click', function( e ){
var offset = $( this ).offset(),
left = ( e.pageX - offset.left ),
totalWidth = $( this ).width(),
percentage = ( left / totalWidth );
video.currentTime = video.duration * percentage;
})
$( '#play_button' ).on( 'click', function() {
if ( video.paused ) {
video.play();
$( this ).html( '❚❚' ) /* Pause */
} else {
video.pause();
$( this ).html( '►' ) /* Play */
}
} )

.player {
position: relative;
width: 400px;
margin: 0 auto
}
#video {

#custom-seekbar {
position: absolute;
