Dette er måske en meget! omstændig løsning (introduktion af to nye funktioner) ...
men jeg kan ikke få roenving's r.selectedIndex.value til at virke ....
Here goes... Jeg ved i hvert fald at det virker...
<html>
<SCRIPT>
function getSelectedRadio(buttonGroup) {
// returns the array number of the selected radio button or -1 if no button is selected
if (buttonGroup[0]) { // if the button group is an array (one button is not an array)
for (var i=0; i<buttonGroup.length; i++) {
if (buttonGroup[i].checked) {
return i
}
}
} else {
if (buttonGroup.checked) { return 0; } // if the one button is checked, return zero
}
// if we get to this point, no radio button is selected
return -1;
} // Ends the "getSelectedRadio" function
function getSelectedRadioValue(buttonGroup) {
// returns the value of the selected radio button or "" if no button is selected
var i = getSelectedRadio(buttonGroup);
if (i == -1) {
return "";
} else {
if (buttonGroup[i]) { // Make sure the button group is an array (not just one button)
return buttonGroup[i].value;
} else { // The button group is just the one button, and it is checked
return buttonGroup.value;
}
}
} // Ends the "getSelectedRadioValue" function
function fun(formEle,event)
{
cmd = getSelectedRadioValue( formEle );
alert(event+cmd);
}
</SCRIPT>
