Question

First off, here’s my code:

var variable1 = 10;
function f1 (){
  alert(variable1);
}
//When button is pressed, call function
$("#button").click(f1);

Why can I not access variable1 inside the function?

$(document).ready(function() {
  var how_many_words = 3;
  alert(how_many_words); //This happens

  $("input").keypress(check_word);

  function check_word() {
    alert('hello'); //This happens
    alert(how_many_words); //This doesn't
  }
});

Here’s the definitive answer to what my problem was, courtesy of this website. I foolishly named one of my variables the same as an id and a function. Insanity! I apologise for wasting people’s boxing days. Thanks for all your help.
