I doing some web development using Javascript and HTML. I am trying to use Javascript to programmatically change one of the text values when a button is pressed. So far pushing the button has done nothing and the debugger reads the error "Cannot set property 'innerhtml' of null". What is wrong and how can I fix the error?

You probably have a line of code that looks something like this:

document.getElementById('whatever').innerHTML = "New inner HTML";

The error you're describing is likely ocurring because the element that you're trying to get doesn't exist. Some possible reasons are:

  • The script is running before the element is created (move the script to the bottom of the page)
  • The element doesn't exist at all, your selectors have a typo, or your code is otherwise selecting the wrong element
