Error message ".innerHTML is not a function" [duplicate]

Question

I'm trying to fill the date automatically in a table header, but all I get is

".innerHTML is not a function"

I've looked everywhere, and tried put my code at the top and bottom of the page, but nothing works. Help, please!

window.onload = function() {
  var currentTime = new Date();
  var month = currentTime.getMonth() + 1;
  var day = currentTime.getDate();
  var year = currentTime.getFullYear();
  document.getElementById("dated").innerHTML(month + "/" + day + "/" + year);
};

Answer 1

Well, as the error says, innerHTML is not a function.

You can assign a value to the property, though:

document.getElementById("dated").innerHTML = month + "/" + day + "/" + year;

For more infos, have a look at the MDN docs.

Answer 2

innerHTML is a property... thus you need to use = not ()... it's not jQuery.

document.getElementById("dated").innerHTML = "blah"

Answer 3

document.getElementById("dated").innerHTML = month + "/" + day + "/" + year;
