TimeRanges 接口用于表示一组时间范围,主要用于跟踪在加载 和 元素时缓冲了哪些媒体部分。 TimeRanges 对象包含一个或多个时间范围,每个时间范围由开始和结束时间偏移量指定。您可以通过使用 start() 和end() 方法引用每个时间范围,并传递要检索的时间范围的索引号。 术语“标准化 TimeRanges 对象” 表示此类对象中的...
TimeRanges* buffered = m_attachedElement->buffered();// 1. If the HTMLMediaElement.buffered attribute returns an empty TimeRanges object, then// return an empty TimeRanges object and abort these steps.if(buffered->length() ==0)returnTimeRanges::create();// 2. Return a single range with a ...
TimeRanges* sourceRanges = activeRanges[i];if(mReadyState == MediaSourceReadyState::Ended) {// Set the end time on the last range to highestEndTime by adding a// new range spanning the current end time to highestEndTime, which// Normalize() will then merge with the old last range.sou...
buffered 属性返回 TimeRanges 对象。 TimeRanges 对象表示用户的音视频缓冲范围。 缓冲范围指的是已缓冲音视频的时间范围。如果用户在音视频中跳跃播放,会得到多个缓冲范围。 浏览器支持 所有主流浏览器都支持 buffered 属性。 注释:Internet Explorer 8 或更早的浏览器不支持该属性。 语法 audio|video.buffered AI代码...
综上所述,当你遇到“uncaught domexception: failed to execute 'end' on 'timeranges': the index pr”错误时,应检查你调用end方法时使用的索引是否有效,并确保在调用之前进行适当的验证。这样可以避免索引超出范围的情况,从而防止错误的发生。
TimeRanges.lengthRead only Returns anunsigned longrepresenting the number of time ranges represented by the time range object. Methods TimeRanges.start() Returns the time for the start of the range with the specified index. TimeRanges.end() ...
