What are the possible reasons for document.getElementById$("#id") or any other DOM method / jQuery selector not finding the elements?

Example problems include:

  • jQuery silently failing to bind an event handler
  • jQuery "getter" methods (.val().html().text()) returning undefined
  • A standard DOM method returning null resulting in any of several errors:

    Uncaught TypeError: Cannot set property '...' of null Uncaught TypeError: Cannot read property '...' of null

    the most common forms are:

    Uncaught TypeError: Cannot set property 'onclick' of null

    Uncaught TypeError: Cannot read property 'addEventListener' of null

    Uncaught TypeError: Cannot read property 'style' of nullWhat are the possible reasons for document.getElementById, $("#id") or any other DOM method / jQuery selector not finding the elements?

    Example problems include:

    • jQuery silently failing to bind an event handler
