Show SPAN depending on value
I have a form select object that used to loads it's values from a text file. I had some code that depending on the selectIndex it will display additional inputs. Code as follows:
php Code:
Original - php Code 
  1.  
  2. <script language="JavaScript">
  3. function showDiv( id ) { 
  4. if ((daily_staffing.type.selectedIndex == 1) || (daily_staffing.type.selectedIndex == 6) || (daily_staffing.type.selectedIndex == 14)) 
  5. { 
  6. document.all[ id ].style.display = 'block'; 
  7. }
  8. else
  9. { 
  10. document.all[ id ].style.display = 'none';  
  11. document.daily_staffing.time_from.value="";
  12. document.daily_staffing.time_to.value="";
  13. document.daily_staffing.total_hours.value="";
  14. }
  15. }
  16. </script>


Problem that I have now is that with my the new mySQL server, I now load the list from a database and can easily add more options to the drop-down. Since the same 3 basic options will be the only ones that make the above span appear, I want to be able to modify the if so that instead of using the selectedIndex it uses the actual value. For example: selectedIndex 1 will always have the value of "AL". So, I want to have the span show regardless of the index location of the "AL" value.

Hopefully I explained myself properly.

Any help would be appreciated.

RE: Show SPAN depending on value
you could try something like
php Code:
Original - php Code 
  1.  
  2. <script language="JavaScript">
  3. function showDiv( id ) { 
  4. if ((daily_staffing.type.options[daily_staffing.type.selectedIndex].value == "AL")) 
  5. { 
  6. document.all[ id ].style.display = 'block'; 
  7. }
  8. else
  9. { 
  10. document.all[ id ].style.display = 'none';  
  11. document.daily_staffing.time_from.value="";
  12. document.daily_staffing.time_to.value="";
  13. document.daily_staffing.total_hours.value="";
  14. }
  15. }
  16. </script>
