javascript - TypeError: video is null - what is it? -

i have video on page, loaded async ..

<video controls="" id="galmainvideo" class="galmainvideo" style="margin:0 auto;">     <source src="https://examplde.com/video/10.mp4" type="video/mp4">     browser not support video tag. </video> 

no try pause/stop when do

var vid = document.getelementbyid("#galmainvideo"); vid.get(0).pause(); 

i error typeerror: vid null

what it? doing wrong here?

it means there no element inside vid. there isn't id = "#galmainvideo". remove "#".

var vid = document.getelementbyid("galmainvideo"); 

in jquery works:

   var vid = $("#galmainvideo");
