HTML onloadeddata属性用法及代码示例

HTML onloadeddata属性是事件属性，当加载当前帧数据但下一帧的数据不足以播放音频/视频时，会发生此事件。

用法:

<element onloadeddata="myScript">

属性值：此属性包含单值脚本，该脚本在调用onloadeddata事件属性时起作用。 <audio>和<video>标签支持此属性。

范例1：

<!DOCTYPE html> 
<html> 
    <head> 
        <title> 
            HTML onloadeddata Attribute 
        </title> 
    </head> 
  
    <body> 
        <center> 
            <h1 style="color:green;">

            </h1> 
            <h2>
