Send Radio Section back to opener

[PSFMIS]

I'm sending a for text field back to a parent window like this:

opener.document.Form1.txtField1.value = MainForm.txtField1.value;

I also want to send a Radio button selection back... I have not been successful. Could someone help?

Thanks,
Aaron

Have you tried "parent" instead of "opener"?

Also: "document.MainForm." instead of just "MainForm."

Radio buttons make up an array (all the buttons of the same name are in it). For example, if you have three buttons as so:

<input type='radio' value='Yes' name='Answer' />Yes
<input type='radio' value='No' name='Answer' />No
<input type='radio' value='Yes' name='Answer' />Maybe

...then, in your JavaScript, you need to cycle through them to find which is checked:

for(var i=0; i<document.MainForm.Answer.length; i++)
{
 if(document.MainForm.Answer[i].checked)
 {
  parent.document.Form1.someElement.value = document.MainForm.Answer[i].value;
  break;
 }
}

Tell us more... Is the "lower" page inside an IFRAME or in a window of its own? ...or did it open in the same window as the page that called it (in which case, you will need to take a very different approach!).

I should clarify. I want to send the radio selection upon clicking a form Submit button rather than onclick for each radio selection. Is this possible?

Do I have to use onclick to send the value of each radio button when its selected?

Or is ther something like this:
opener.document.Form1.txtField1.value = MainForm.txtField1.selectedValue;

I'm new to javascript so that for loop looks a little strange to me.. It's looks like what I had in mind if there was no MainForm.RadioFrom1.selectedValue or anything like that to use.

Could you explain this like to me?

for(var i=0; i<document.MainForm.Answer.length; i++)

Well, if the Submit button is in the "lower" page, you can include an onclick event in the button which calls a function on that page which evaluates the value of the checked radio button and sends that back.

SELECT (drop-down) lists have that wonderful selectedIndex feature, but, sadly, radio buttons do not have an equivalent.

I am assuming the name of the form on the page this is being done is called "MainForm" and the radio buttons on that form are named "Answer". As I mentioned, radio buttons of the same name make up an array, so they have a "length" property which indicates how many elements are in the array. To cycle through that array, then, you must start at the 0-index (arrays are 0-based) and go up to the highest index, which is equal to length-1 (which is why it's "i<document..." and not "i<[red]=[/red]document..."). The i++ just increments i by one. The general construct of a for-loop is:

for(initialization; conditional; increment){instructions}

Steps:
(1) initialization

(2) evaluation of conditional.

(2a1)If conditional is true, follow instructions
(2a2)do whatever is in the increment part of the command (it doesn't actually have to be a form of incrementation)
(2a3)repeat (2), above

(2b) If conditional is false, skip the loop and move on.

I'm sure you already knew a lot of this, but wasn't quite sure how much you were asking for.

Actually that clears it up very well. I was just hoping I wouldn't end up having to evaluate every Radio group since I have 28 of them.

Thanks,

Well, if you name them cleverly, you can do it dynamically. If, for example, they are: radioGroup0, radioGroup1, etc.

for(var x=0; x<28; x++)
{
 var radioGroup = document.forms["MainForm"].[b]elements["radioGroup"+x][/b];
 for(var i=0; i<radioGroup.length; i++)
 {
  if(document.MainForm.Answer[i].checked)
  {
   parent.document.forms["Form1"].[b]elements["someElement"+x][/b].value = radioGroup[i].value;
   break;  [i]//if this breaks out of BOTH for-loops, then drop it.[/i]
  }
 }
}

Can you follow what I did here?

I follow... I already have them all named so i think Ill just create one and copy paste / change names.

thanks
