Can I Use Javascript To Dynamically Change A Video's Source?


Answer :

Sure,

  1. You can set the src attribute on the source element:

    document.querySelector("#myVideoTag > source").src = "http://example.com/new_url.mp4"

    Or using jQuery instead of standard DOM methods:

    $("#myVideoTag > source").attr("src", "http://example.com/new_url.mp4"​​​​)​

  2. Then you need to call the load method on the video element:

    videoElement.load()


I have faced this problem several times and based on previous experience and digging I can suggest these options:

  • replace video tag completely

yes, just re-insert <video> element with new sources. It's straightforward, but effective approach. Don't forget to re-initialize event listeners.

  • assign video URL to video.src

this I saw a lot in answers here, on stackoverflow, and also in sources on github.

var video = document.getElementById('#myVideo'); video.src = newSourceURL;

It works, but you cannot provide browser options to choose from.

  • call .load() on video element

according to documentation you can update src attributes for <video>'s <source> tags and then call .load() to changes take effect:

<video id="myVideo">     <source src="video.mp4" type="video/mp4" />     <source src="video.ogg" type="video/ogg" /> </video>  <script>     var video = document.getElementById('myVideo');     var sources = video.getElementsByTagName('source');     sources[0].src = anotherMp4URL;     sources[1].src = anotherOggURL;     video.load(); </script>

Nevertheless here it's said that there're problems in some browsers.

I hope it will be useful to have this all in one place.


I have run into the same problem. According to this thread:

changing source on html5 video tag

it is not possible to change the src of the source tag. you will have to use src of the video tag itself.

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
