Form approach As scoota269 says  you should use onSubmit instead  cause pressing enter on a textbox will most likey trigger a form submit  if inside a form   lt form action  quot   quot  onsubmit  quot handle quot  gt       lt input type  quot text quot  name  quot txt quot    gt   lt  form gt    lt script gt      function handle e           e preventDefault       Otherwise the form will be submitted          alert  quot FORM WAS SUBMITTED quot           lt  script gt   Textbox approach If you want to have an event on the input-field then you need to make sure your handle   will return false  otherwise the form will get submitted   lt form action  quot   quot  gt       lt input type  quot text quot  name  quot txt quot  onkeypress  quot handle event  quot    gt   lt  form gt    lt script gt      function handle e           if e keyCode     13               e preventDefault       Ensure it is only this code that runs              alert  quot Enter was pressed was presses quot                     lt  script gt
