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 https://forums.phpfreaks.com/topic/3529-drop-down-list-problem/#findComment-12159 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.
