Can I create an HTML5 video element dynamically and access it using APIs like document.getElementById or Name without displaying it on the webpage?
Is there a way to hide the video element after creating it, similar to div.hide() or something along those lines?
If you're looking to add a video to your website, try the following code snippet:
const newVideo = document.createElement('video');
newVideo.src = 'pathToVideo.mp4';
newVideo.autoplay = true;
You can also utilize the canPlayType method to verify if the browser supports the video format before setting the source:
if (newVideo.canPlayType('video/mp4').length > 0) {
/* set the video source */
}
The method will return either maybe or perhaps based on the browser compatibility. An empty string indicates that the format is not supported.
Once you have created the video element, you can use it with the API and insert it into the DOM as needed. Feel free to save it globally for future use. Hope this information proves helpful!
Yes, it is possible to create everything using JavaScript without the need for any pre-existing elements in the HTML body.
Here is a straightforward way to create a video element using JavaScript:
var videlem = document.createElement("video");
/// ... set up parameters like poster image, size, position, etc.
/// now, add video sources:
var sourceMP4 = document.createElement("source");
sourceMP4.type = "video/mp4";
sourceMP4.src = "path-to-video-file.mp4";
videlem.appendChild(sourceMP4);
//// repeat the process for ogg/ogv and webm sources
Before proceeding with this, it's important to check if the browser supports the video element and which file formats can be played. This can be done as follows:
var supportsVideoElement = !!document.createElement('video').canPlayType;
If the video element is supported, you can test which video formats are compatible:
var temp = document.createElement('video');
var canPlay_MP4 = temp.canPlayType('video/mp4; codecs="avc1.42E01E,mp4a.40.2"');
var canPlay_OGV = temp.canPlayType('video/ogg; codecs="theora,vorbis"');
var canPlay_WEBM = temp.canPlayType('video/webm; codecs="vp8,vorbis"');
After ensuring compatibility, you can dynamically add the video element to your page using only JavaScript with the appropriate video sources set. In case of issues related to server-side configurations, adding certain directives to .htaccess might resolve the problem:
AddType video/ogg .ogv
AddType video/ogg .ogg
AddType video/mp4 .mp4
AddType video/webm .webm
This step may or may not be necessary depending on server settings. If playback issues persist from the server but not locally (e.g., localhost), including the above lines in .htaccess within the same folder as the video files could address the problem.
To make the video element accessible via getElementById(...), simply assign an ID during creation:
var videlem = document.createElement("video");
videlem.id = "xxxxxx";
Later on, you can easily locate the element using:
var videlem = document.getElementById("xxxxxx");
While setting an ID can facilitate access, it may not be required if the element has already been created and referenced by a variable - in such cases, direct usage is preferred.
I trust this information proves helpful :-)
Here is an updated and streamlined method to accomplish the task at hand, especially for those being directed here through Google searches:
let videoElement = document.createElement("VIDEO");
if (videoElement.canPlayType("video/mp4")) {
videoElement.setAttribute("src","movie.mp4");
}
else {
videoElement.setAttribute("src","movie.ogg");
}
videoElement.setAttribute("width", "320");
videoElement.setAttribute("height", "240");
videoElement.setAttribute("controls", "controls");
document.body.appendChild(videoElement);
