Question

I am trying to check whether content inside body tag is null or not.

Should I use regex for this or is there any other way to handle this like using any jQuery selector?

Your suggestion and help will be appreciated.

Answer 1

The content within the body-tag will never be null, it could however be empty.

If you use jQuery you could to something like this:

if ($("body").html() === ""){
   // Do something if body is empty
}

With plain javascript:

if (document.body.innerHTML === ""){
   // Do something if body is empty
}
