Only when all conditions have been satisfied do we reach the command, in which case the form will be submitted.
When a visitor enters information into a web form displayed in a web browser and clicks the submit button, the information is sent to a server where a server-side script or application processes it.
I would change the line if (radios[i].checked) form Valid = true; to if (radios[i].checked) so it becomes true with the value of the checked item. Also, always use braces, even if there is just one item.
All you need to do is to provide the second group of radio buttons with a different name to that used for the first group.
A friend recently asked for a code sample showing Java Script being used to client-side validate the radio inputs of an HTML form.
The server responds by sending the processed information back to the user (or client), or by performing some other action based on the form’s contents.
You can create forms that submit data to most application servers, including PHP, ASP, and Cold Fusion.It can prevent people from leaving fields blank, from entering too little or too much or from using invalid characters.For an alternative approach to client-side form validation, without Java Script, check out our new article on HTML5 Form Validation which is available now in most modern browsers.When form input is important, it should always be verified using a secure server-side script.Otherwise a browser with Java Script disabled, or a hacker trying to compromise your site, can easily submit invalid data. The first test in the example is therefore only necessary in order to provide a different error message when the input is blank.Can only use HTML CSS and Java Script for this, I know it's 1000 times easier in jquery but sadly I can't use that.
