Problem w/ onsubmit and hidden variables

Posted 24 May 2011 - 12:29 PM

Trying to get this code to insert javascript variables into hidden fields in form using "function populateHiddenFields(f)" . Any thoughts on what I have wrong? onsubmit command? variable definitions? i cant seem to close the loop. No error, just no variables inserted.

ie: the javascript works with a simple hidden form and alerts... see here.

something just isnt right with adding variables to the new hidden fields.

do you mean in lines 93-100 or 170-180...?

should it be...
function populateHiddenFields(f) { 
      f.source.value  = input_1_10; 
      f.medium.value  = input_1_11; 
      f.term.value    = input_1_12; 
      f.content.value = input_1_13; 
      f.campaign.value = input_1_14; 
      f.segment.value = input_1_15; 
      f.numVisits.value = input_1_16;

input_1_10 will still be undefined as it is a mere global variable. you would probably need something like f.source.value = document.forms[0].input_1_10.value; when you want to read form fields.
