If you want to do some checks then use this way    lt select size  1  name  links  onchange  functionToTriggerClick this value   gt       lt option value    gt Select a Search Engine lt  option gt               lt option value  http   www google com  gt Google lt  option gt       lt option value  http   www yahoo com  gt Yahoo lt  option gt   lt  select gt    lt script gt      function functionToTriggerClick link          if link                 window location href link                      lt  script gt

To select an option  use  val  value-of-the-option   on the select element  To trigger the change element  use  change   or  trigger  change     The problems in your code are the comma instead of the dot in     check   trigger  change    and the fact that you call it before binding the event handler

Use val   to change to the value  not the text  and trigger   to manually fire the event   The change event handler must be declared before the trigger   Here s a sample      check   change function      var data    this  val      alert data                        check        val  two        trigger  change
