Given a reference, form, you could check the group with either of the following expressions.A friend recently asked for a code sample showing Java Script being used to client-side validate the radio inputs of an HTML form.It makes your page much more user-friendly, and takes out the frustration of having to fill out the same form repeatedly.It's also very precise, as you can point out the exact field where there's a problem.Form validation is the process of checking that a form has been filled in correctly before it is processed.
If one isn't checked I want it to post an alert message.
If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.
This is great but comes with the inevitable HTML5 caveats that it just can't be relied on across all browsers. So in order to get this two arrays are created to store all the names and then refine that list of the unique names.
When you submit a form to a CGI program that resides on the server, it is usually programmed to do its own check for errors.
If it finds any it sends the page back to the reader who then has to re-enter some data, before submitting again.
If you have suggestions for other approaches, or additional questions related to this example, be sure to email me. For more information, you'll want to keep a good Java Script reference manual handy.
