Hi,
I have a list of option for checkbox.
Example: gender = Don’t Know, Male, Female
I want to disable the Male and Female checkbox when I clicked “Don’t know”.
At the JavaScript > onclick, when I tried on radio button, I managed to do it but I cannot apply on checkbox. Please help. Thanks.
if(document.F1.gender[0].checked){
document.F1.gender[1].disabled = true;
document.F1.gender[2].disabled = true;
}else{
document.F1.gender[1].disabled = false;
document.F1.gender[2].disabled = false;
}
