Menu
I have 3 of the 4 following script functions working. (See below)
The ‘getSBox(ids)’, getRBtn(nameinfo)’ and ‘getCBox(ids)’ all work
to return the value of the option selected within the element.
For consistency I want to create a ‘getRBtn(ids)’.
My attempt, commented out in the script, is called ‘getRBtnID(ids)’.
I am trying to determine the options array values from the id.
Does anyone have a suggestion(s) how I might do this in the test script below?
Thanks for any ideas. ?

function getSBox(ids) {
var sel = document.getElementById(ids); // alert(sel+’nvalue:’+str);
var fnd = -1;
for (var i=0; i<sel.options.length; i++) { if (sel.selectedIndex == i) { fnd = i; } }
// return fnd; // return selected index of selection
// comment out next 3 lines if selectIndex used in line above
var str = “”;
if (fnd != -1) { str = sel.options[fnd].value; }
return str;
}
function getRBtn(nameinfo) {
var sel = document.getElementsByName(nameinfo); // alert(nameinfo+’n’+sel);
var fnd = -1;
var str = ”;
for (var i=0; i<sel.length; i++) {
if (sel[i].checked == true) { str = sel[i].value; fnd = i; }
}
// return fnd; // return option index of selection
// comment out next line if option index used in line above
return str;
}
