How can I inject my google extension javascript after content gets added by the site's own java-CodePudding

I am trying to make a google extension that manipulates a video player. The problem is that the video player gets loaded with javascript and the injected javascript is unable to find the element, resulting in an error.

If you use jQuery, there is a very easy way to do this through getScript function. Just add the part of script that you need to be executed after the load and pass it as a parameter to the function.

$.getScript( "app.js" )
  .done(function( script, textStatus ) {
    console.log( textStatus );
    //your remaining code
  })
  .fail(function( jqxhr, settings, exception ) {
    //script fail warning if you want it
});
