Make a for-loop from 22 document.form.value statements

I am close -- but no cigar.   I have a series of 22 forms that save input values (scores) and then pass to one "super" form that then sends to a response page.  How do I write these statements in a more compact for-loop?   Writing in Javascript document.write statements is cumbersome, but sometimes necesary since this will involve making these into either an array or variables .

function final_results() {
         // assigns values to the final input value <--- from each of 22 forms values
        document.results_form.finalTotal1.value =;
      document.results_form.finalTotal2.value =;
      document.results_form.finalTotal3.value =;
      document.results_form.finalTotal4.value =;
      document.results_form.finalTotal5.value =;
      document.results_form.finalTotal6.value =;
      document.results_form.finalTotal7.value =;
      document.results_form.finalTotal8.value =;
      document.results_form.finalTotal9.value =;
      document.results_form.finalTotal10.value =;
      document.results_form.finalTotal11.value =;
      document.results_form.finalTotal12.value =;
      document.results_form.finalTotal13.value =;
      document.results_form.finalTotal14.value =;
      document.results_form.finalTotal15.value =;
      document.results_form.finalTotal16.value =;
      document.results_form.finalTotal17.value =;
      document.results_form.finalTotal18.value =;
      document.results_form.finalTotal19.value =;
      document.results_form.finalTotal20.value =;
      document.results_form.finalTotal21.value =;
      document.results_form.finalTotal22.value =;
      return document.results_form.finalTotal1.value;    
      return document.results_form.finalTotal2.value;    
      return document.results_form.finalTotal3.value;    
      return document.results_form.finalTotal4.value;    
      return document.results_form.finalTotal5.value;    
      return document.results_form.finalTotal6.value;    
        return document.results_form.finalTotal7.value;    
      return document.results_form.finalTotal8.value;    
      return document.results_form.finalTotal9.value;    
      return document.results_form.finalTotal10.value;    
        return document.results_form.finalTotal11.value;    
      return document.results_form.finalTotal12.value;    
      return document.results_form.finalTotal13.value;    
      return document.results_form.finalTotal14.value;    
      return document.results_form.finalTotal15.value;    
      return document.results_form.finalTotal16.value;    
      return document.results_form.finalTotal17.value;    
      return document.results_form.finalTotal18.value;    
      return document.results_form.finalTotal19.value;    
      return document.results_form.finalTotal20.value;  
      return document.results_form.finalTotal21.value;    
      return document.results_form.finalTotal22.value;    
      document.results_form.totalscore.value = ????
      return document.results_form.totalscore.value;

The final document.results_form.totalscore.value is a summation value that could be an increment statement or a final addition of all of the above.

Tight, economical code always greatly appreciated.

I hope I did without errors :)

in every form add keyword "this" on onsubmit attribute

like this:
<form onsubmit="return final_results(this)">

and the function:

function final_results(obj)
      // assigns values from the 22 forms into an input of the final super form
            var total=0;
            for(var i=1;i<23;i++)
                  eval("document.results_form.finalTotal"+i+".value =;")
                  return false;
               document.results_form.totalscore.value = total;
            return true;


         Not sure of the process, but I think that you are trying to call this function only once ( rather than at the end of each form [ maybe? ] )... Anyway, this will only have to be called once:

function final_results() {
   var tot = 0
   for ( var i = 0 ; i < 3 ; ++i )
      eval("document.forms['destForm'].finalTotal" + i ).value = document.forms['form'+i].total.value
      tot += parseFloat(document.forms['form'+i].total.value)

   document.forms['destForm'].FINAL.value = tot

<body onload=final_results()>
<form name="form0">
<input type=text name="total" value='2'></input>

<form name="form1">
<input type=text name="total" value='4'></input>

<form name="form2">
<input type=text name="total" value='6'></input>

<form name="destForm">
<input type=text name="finalTotal0">
<input type=text name="finalTotal1">
<input type=text name="finalTotal2">

<input type=text name="FINAL">

Again ... thanks for such a speedy response.  I need to work through this and get back to both of you in a few hours (I am still at work)  ...  I  think this is right.  

The partial answer is, yes, this is supposed to be a one time call at the end of complete of the 22 forms.   So each of the 22 forms needs to call up an "upTotal"  function that totals the results.  The superform just inputs these total values all at once to post to the response page.

The example given provides the total in the "FINAL" input box, there is no need call another 'upTotal' function; anyway, see how it goes ;-)
Hi bodywise,

Here is the code you have, (basically), in compact form. I do not understand why you need to "return" all of those values, or where you are returning them to. If you can show me more of your code, I could maybe understand.

Here is the script:

function final_results(){
         num = i+1;
         var num = num.toString();
         getForm = document.forms['form'+num].total.value;
         document.results_form.elements['finalTotal'+num].value = getForm;
         grand_total += parseInt(getForm);
     document.results_form.totalscore.value = grand_total;

Are you calling the results from the "final_results()" function from inside another function, or why the "return" statements?

Anyway, hope that helps.

Gee.  Thanks to all of you.   This has been a very short and sweet interchange.  I went with the simplest and most effective solution from aaron, although I think the other suggestions from all of you would work as well.  Eadh teaches me just a slight variation. is another very clever convention that I have not used.

Here is what I learned that I did not quite understand.

1. form can be named as forms['form'+i]    most clever and most compact

2. the part eval("document.forms['destForm'].finalTotal" + i ).value  is what I was looking for.  I could not figure out how to phrase this and the end  == finalTotal" + i ).value ==  was just not apparent to me.  It works!

3. the increment counter works just right -- I think -- although it is not the absolute critical value.  the 22 total scores are the important variables that are passed to the response page

4. the <body onload> statement is probably critical to setting up the "re-evaluation" process

5. I had to change the counter from 0 to 1 since my forms are named as form1, form2 etc and not form0, form1 ...  The 0 array system still confuses me greatly.   I seem to remember that Pascal allows you to change array counting from 0 to 1.  I don't think you have that option in JS so I just put dummmy text in the first array element.

hope to encounter you again with any remianing problems.bodywise

Great, happy to see that u learnt so much... I am still constantly learning new and improved ways of coding in JScript - its a fairly amazing language ( well I think anyway )

bodywiseAuthor Commented:
Indeed.  I have programmed in TurboPascal, PHP, ASP, a tiny bit of Fortran, Basic, and here comes along Javascript.  Yes, it is a rather amazing scripting language.

Thank you to all of the above for succinct and relevant answers.
