kenrbnsn Posted February 22, 2006 Share Posted February 22, 2006 This is a Javascript question, not a PHP question.Create a normal hard coded HTML form and get your javascript working, then put in your PHP.Ken Quote Link to comment Share on other sites More sharing options...
hitman6003 Posted February 22, 2006 Share Posted February 22, 2006 Change your onchange to this:onchange="javascript: go(this, this.selectedIndex);"Change your JS function to this:<script type="text/javascript">function go(x, y) { alert (x[y].value);}</script>Please post your questions in the proper forum in the future...this should be in the Javascript forum.
