Here is what the complete HTML for one of the buttons would look like: parameters are redundant in some browsers.
There browsers, however, are often not smart enough to recognize the nesting, so it is worth putting them in to maximize the number of browsers in which the code will function.
The solution here is to give all of the radio buttons within the group the same name but different values.
Here is the code used for the radio button themselves.
After you get the response token, you need to verify it with re CAPTCHA using the following API to ensure the token is valid.
It will return the value of the button within the group that is selected, or return a null value if no button in the group is selected.
For example, here is the code that will perform the radio button validation: event attached to the validate (or submit) button on the form.
Browsers that support HTML5 email address validation include Safari 5 , Google Chrome 6 , Mozilla Firefox 4 and Opera 10 .
Safari 5 and Google Chrome 6-8 will not accept invalid email address input but, unlike the other browsers, will not help the user correct the error.
