Resets the audio or video object and loads a new media resource.

Syntax

object.load();

Parameters

This method has no parameters.

Return value

This method does not return a value.

Standards information

HTML5 A vocabulary and associated APIs for HTML and XHTML, Section 4.8.9.5

Remarks

This method causes any pending tasks or events to be discarded. Use this method when changing URLs on an audio or video object where the source element was used to initially set the media.

Examples

This example shows how to use the load method to change a video. To use it, start the video, and then put a different video address into the text field, and press Play. This example doesn't use the source element, but uses load to reset the video element to start playing a new video.
