Question

I need to submit just one input field value to a cgi script via a web form.

I’ve added a couple of extra form controls (a check box and radio buttons) which manipulate the input value depending on the states selected.

When the form is submitted, the extra form field values are submitted as well which breaks the cgi script (which I don’t have access to). I removed the ‘name’ attribute from the check boxes so they are not submitted but cannot do this for the radio buttons as it breaks their grouping.

How can I prevent radio button values from being submitted?

Answer 1

You can add a disabled attribute to them in the submit handler, this will prevent them from being serialized, either by jQuery or a normal <form> submission. For example:

$("#myForm").submit(function() {
  $(this).find(":radio, :checkbox").attr("disabled", true);
});

Or you can .serialize() only the elements you want, for example:

$.post("myPage.cgi", $("#myForm input[type=text]").serialize());
