function disableGroup(which, formName, groupName) {
var val = which.value;
val = val.replace(/^\s+|\s+$/g,""); // strip leading and trailing spaces
which.value = val; // write amended val back to text field
if (val.length > 2) { // at least three characters entered
for (var i=0; i<formName.elements.length; i++)

Ok, I do not know what are you trying to do here, i tried jquery before as it was not working, my question is the above may be fine and may work for one set of radio button, but what if i have 3 set of radio buttons with yes/no values and one textarea
then what my approch will be..
and on the clearence of textbox value, it should clear all values from the radio buttons and the textarea..
the current code mine is working the way it is but it is working for one set of radio button and i am trying to make it work by using in moe than 3 or 4 sets of radio buttons

ok,
Have annotated text, have added textarea as mentioned on para 3 above, I clear checked values/disable buttons/clear text from textarea and text content when top text box is empty.
