How do you display values in a textarea using javascript.

ex. i have 2 radio buttons

o Adult =$9.99
o Child =$6.99

i need it to be, so that if i select adult in the radio button option , it will display 9.99 in my textarea at the other frame. Cause im using 2 frames for this html file. The radio buttons are at the left frame and the textarea is at the right frame.

  1. function setTextAreaVal(val) {
  2.     //First of all, you need to access the right frame.
  3.     //assuming the name of the frame is "right".
  4.     var frame = top.right;
  5.     // Then you need to access the textarea.
  6.     //If using the ID
  7.     var textarea = document.getElementById("textarea");
  8.     //Alternatively, if using the name, you also need the form name, e.g.
  9.     //var textarea = document.forms[formname].elements[textareaname];
  10.     //Finally, set the value using the value property.
  11.     textarea.value = val;
  12. }
Call the function onclick, e.g. onclick="setTextAreaVal(this.value)".
