/ / Network status

Media.currentSrc; / / returns the URL of the current resource

Media.src = value; / / returns or sets the URL of the current resource

Media.canPlayType (type); / / whether resources in a certain format can be played

Media.networkState; / / 0. This element is not initialized 1. Normal but not using network 2. Downloading data 3. No resources found

Media.load (); / / reload the resources specified by src

Media.buffered; / / returns the buffered region, TimeRanges

Media.preload; / / none: do not preload metadata: preload resource information auto:

/ / status of preparation

Media.readyState; / / 1:HAVE_NOTHING 2:HAVE_METADATA 3.HAVE_CURRENT_DATA 4.HAVE_FUTURE_DATA 5.HAVE_ENOUGH_DATA

Media.seeking; / / whether it is seeking or not

/ / playback status

Media.currentTime = value; / / the current playback position, which can be changed by assignment

Media.startTime; / / is generally 0, but not 0 if it is a streaming media or a resource that does not start from 0

Media.duration; / / the current resource length stream returns infinite

Media.paused; / / whether to pause

Media.defaultPlaybackRate = default playback speed of value;//, which can be set

Media.playbackRate = value;// current playback speed, change immediately after setting

Media.played; / / returns the area that has been played, TimeRanges. For this object, see below

Media.seekable; / / returns the region TimeRanges that can be seek

Media.ended; / / whether to end or not

Media.autoPlay; / / whether to play automatically

Media.loop; / / whether to play in a loop or not

Media.play (); / / playback

Media.pause (); / / pause

/ / Control

Does Media.controls;// have a default control bar?

Media.volume = value; / / Volume

Media.muted = value; / / mute

/ / TimeRanges (region) object

Number of TimeRanges.length; / / region segments

Start position of TimeRanges.start (index) / / paragraph index area

TimeRanges.end (index) / / the end of the index area

Events:

Js code

EventTester = function (e) {

Media.addEventListener (eQuery function () {

Console.log ((new Date ()). GetTime (), e)

});

}

EventTester ("loadstart"); / / the client starts to request data

EventTester ("progress"); / / the client is requesting data

EventTester ("suspend"); / / delayed download

EventTester ("abort"); / / the client initiatively terminates the download (not caused by an error)

EventTester ("error"); / / encountered an error while requesting data

EventTester ("stalled"); / / Network speed stall

Triggered when eventTester ("play"); / / play () and autoplay start playing

EventTester ("pause"); / / pause () triggers

EventTester ("loadedmetadata"); / / obtain the resource length successfully

EventTester ("loadeddata"); / /

EventTester ("waiting"); / / waiting for data is not an error

EventTester ("playing"); / / start playback

EventTester ("canplay"); / / can be played, but may be paused due to loading

EventTester ("canplaythrough"); / / can be played, and all the songs have been loaded

EventTester ("seeking"); / / searching

EventTester ("seeked"); / / search completed

EventTester ("timeupdate"); / / playback time change

EventTester ("ended"); / / end of playback

EventTester ("ratechange"); / / playback rate change

EventTester ("durationchange"); / / Resource length change

EventTester ("volumechange"); / / Volume change
