It says that TypeError: document.getElementById(…) is null [duplicate]

Answer 1

Make sure the script is placed in the bottom of the BODY element of the document you're trying to manipulate, not in the HEAD element or placed before any of the elements you want to "get".

It does not matter if you import the script or if it's inline, the important thing is the placing. You don't have to put the command inside a function either; while it's good practice you can just call it directly, it works just fine.

Answer 2

I got the same error. In my case I had multiple div with same id in a page. I renamed the another id of the div used and fixed the issue.

So confirm whether the element:

• exists with id
• doesn't have duplicate with id
• confirm whether the script is called

Answer 3

I have same problem. It just the javascript's script loads too fast--before the HTML's element loaded. So the browser returning null, since the browser can't find where is the element you like to manipulate.

Answer 4

All these results in null:

document.getElementById('volume');
document.getElementById('bytesLoaded');
document.getElementById('startBytes');
document.getElementById('bytesTotal');

You need to do a null check in updateHTML like this:

function updateHTML(elmId, value) {
  var elem = document.getElementById(elmId);
  if(typeof elem !== 'undefined' && elem !== null) {
    elem.innerHTML = value;
  }
}

Answer 5

It means that element with id passed to getElementById() does not exist.

Answer 6

You can use JQuery to ensure that all elements of the documents are ready before it starts the client side scripting

$(document).ready(
    function()
    {
        document.getElementById(elmId).innerHTML = value;
    }
);
