This is all just chopped and pasted... hopefully it's about right.
Put this in all of your radio buttons.
onClick="clickRadio(this.name);
and give them each the same name="" but a unique value="". Give the form
and each of the checkboxes unique names too. Then, write this function
in the <head>:
function clickRadio(radioName); {
// Loop through the radio button array to work out which one is
selected.
for (var i = 0; i < document.formName.radioName.length; i++) {
if (document.formName.radioName[i].checked) {
var radioValue = document.formName.radioName[i].value;
}
}
// If they picked "value1",
if (radioValue == "value1") {
// enable the checkboxes beneath it and disable those under
radio2.
document.formName.checkbox1Name.disabled = false;
document.formName.checkbox2Name.disabled = false;
document.formName.checkbox3Name.disabled = true;
document.formName.checkbox4Name.disabled = true;
// Otherwise, if it's "value2",
} else if (radioValue == "value2") {
// do the opposite.
document.formName.checkbox1Name.disabled = true;
document.formName.checkbox2Name.disabled = true;
document.formName.checkbox3Name.disabled = false;
document.formName.checkbox4Name.disabled = false;
}
}
}
Replacing formName with the name of the form and checkboxXName with the
name of each checkbox and value1 and value2 with the actual values
you've assigned to the two radio buttons.
