Javascript (JS) and Forms

Simple events and locating javascript code

• Connecting events, buttons, javascript and text inputs
  
  Points:
  • Practically any JS can appear in the event
  • JS does auto type conversion (+ means concat with strings)
  • Using the DOM
• Connecting events, buttons, javascript and text inputs (again)
  
  Points:
  • You can use eval to evaluate an expression (ANY JAVASCRIPT expression!!).
  • In this case, better to use parseInt
• As above, but defining JS handler elsewhere in this document
• As above, but defining JS handler in a separate document
