如何在SoundManager2中添加歌曲进度条？ [英] How to add a song progress bar in SoundManager2?

问题描述

我正在尝试添加进度条以显示播放期间歌曲的位置。它只需要一个简单的解决方案。我在网上找到了一些代码，它使用SoundManager2 http://www.schillmania.com/projects/soundmanager2/ 调整div宽度以匹配歌曲位置的功能但它似乎不起作用，不确定我哪里出错了，任何帮助都会受到赞赏。

I am trying to add a progress bar to show what position a song is at during playback. It only needs to be a simple solution. I found some code online, which uses SoundManager2 http://www.schillmania.com/projects/soundmanager2/ features to adjust a div width to match the song's position but it doesn't seem to be working, not sure where I am going wrong, any help would be appreciated.

我已经使用了所有必需的Soundmanager2文件和播放的歌曲。它只是进度条的问题。

I have used all the required Soundmanager2 files and playback of the songs work. It's only the progress bar which is the issue.

这里是javascript：

here is the javascript:

soundManager.setup({
url: '/swf',
preferFlash: false,
waitForWindowLoad: true,

onready: function() {

var myTrack1 = soundManager.createSound({
id: 'trackOne', url: 'msamples/beep-1.mp3', volume: 80, autoPlay: false,});
$(".progBar").css('width', ((this.position/this.duration) * 100) + '%');  

$("li.a5 a").click(function(event){soundManager.play('trackOne');});
},

ontimeout: function() {
  // Uh-oh. SWF missing, Flash blocked or other issue
}
});

HTML链接使用此格式，进度条位于以下位置：

The HTML links use this format and the progress bar sits below:

<li class="a5">Song1:
<a href="msamples/beep-1.mp3" title="Play" class="sm2_button">Play</a>
<div id="track1"><div class="progBar"></div></div>
</li>

CSS为：

#track1 {
background-color: #333333;
height: 10px;
margin-top: 10px;
position: relative;
width: 100%;
}

.progBar {
background-color:#FFF;
height:10px;
}

想法是＃track1充当进度条和.progBar的容器是通过 $（。progBar）来调整宽度的div .css（'width'，（（this.position / this.duration）* 100）+'％'）; 代码。

The idea is #track1 acts as the container for the progress bar and .progBar is the div which has it's width adjusted through the $(".progBar").css('width', ((this.position/this.duration) * 100) + '%'); code.

预先感谢您的帮助。

推荐答案

通过在 soundManager.createSound 下添加同时显示：来实现它。我还添加了一个 onfinish：来将进度条重置为 0 最后的宽度。

got it to work by adding the whileplaying: under soundManager.createSound. I also added an onfinish: to reset the progress bar back to 0 width at the end.

  soundManager.createSound({
    id: 'mySound1',
    url: 'msamples/beep-1.mp3',
    whileplaying: function() {
    $(".progBar").css('width', ((this.position/this.duration) * 100) + '%');
        },
    onfinish: function() {
        $(".progBar").css('width', '0');
        }
    });
