How do I change the content of a span element using javascript. .innerHTML method not working

Question

I'm trying to change the content inside of a span element. I've tried :

    <span id='spanId'> content </span>

    document.getElementById('spanId').innerHTML = blah blah

This does not work and the console returns :

'TypeError: null is not an object'

Typo, forgot quotes, syntax error -`document.getElementById('spanId').innerHTML = "blah blah";` — adeneo, Sep 10 '17 at 18:55
have you checked if you have the element with this id? is the page rendered to the end before accessing the element? — Nina Scholz, Sep 10 '17 at 18:56
Why don't you follow a good JS tutorial? This is a very common escenario — Hosar, Sep 10 '17 at 18:57

blah blah is not a recognised value. Put it in between parenthesis "..." so it's recognised as a string and don't forget your semicolon.

document.getElementById('spanId').innerHTML = "blah blah";
