refresh form within a frame

<The idea is to alter the value of a select drop down, and based on the new option, reload a related select drop down.>

It sounds like the best solution would not be to reload the whole page, but rather use javascript to populate it. Here's an example of what you could do:

Code:

<HTML> <HEAD> <script language='javascript'> function updateOptions() { if (document.form1.select1.value == 'CARS') { opt1 = new Option('MAZDA','MAZDA',false,false); opt2 = new Option('TOYOTA','TOYOTA',false,false); document.form1.select2.length=2; document.form1.select2.options[0]=opt1; document.form1.select2.options[1]=opt2; } else if (document.form1.select1.value == 'COLORS') { opt3 = new Option('RED','RED',false,false); opt4 = new Option('GREEN','GREEN',false,false); document.form1.select2.length=2; document.form1.select2.options[0]=opt3; document.form1.select2.options[1]=opt4; } } </script> </HEAD> <BODY> <FORM NAME='form1'> Choose Something from menu 1 <SELECT NAME='select1' onChange='updateOptions()'> <OPTION SELECTED VALUE='CARS'>CARS</OPTION> <OPTION VALUE='COLORS'>COLORS</OPTION> </SELECT> <BR> Now choose something from menu 2 <SELECT NAME='select2'> <OPTION VALUE='MAZDA'>MAZDA</OPTION> <OPTION VALUE='TOYOTA'>TOYOTA</OPTION> </SELECT> </FORM> </BODY> </HTML>
