Javascript validation for radio button
- by Priyanka
Hello.I am doing newsletter subscription.I have 2radio buttons-subscribe and unsubscibe and a submit button.But when I click on submit button,ajax function gets called for subscription.Now i want to do validation.I have written a javascript validation for radio buttons as below:
function validate_radio()
{
var radio_choice = false;
var radio_val = document.newsletterform.subscribe.length;
for (counter = 0; counter < radio_val; counter++)
{
if (document.newsletterform.subscribe[counter].checked)
radio_choice = true;
}
if (!radio_choice)
{
document.getElementById("mandatory").innerHTML="Select Subscribe/Unsubscribe";
return false;
}
}
But now I am getting the validate message but at the same time i am getting subscribed.
tell me a way so that i can stop the subscription being done if the function returns false.
