title: Finding the 'type' of an input element
body: <p>I'd like to be able to find the type of something on the page using JavaScript.
  The problem is as follows:
  I need to check whether a specific area is a checkbox/radio button/ or text field.</p>
  <p>If it's a checkbox or radio button it doesn't have a length (no strings in it), otherwise if it's a textfield I need to check whether or not it contains characters. The page is created dynamically so sometimes a checkbox may be displayed, other times a text field.</p>
  <p>So my thinking is to find the type of the input, then determine what to do.</p>
  <p>Any suggestions would be appreciated.</p>
