Issues With Javascript Validation Of Radio Buttons On Php Form

January 18, 2024 Post a Comment

This is the code for the php file containing the form with radio buttons:

Solution 1:

functionRegValidate(Tester) {
    if ($(":radio[name=w1]:checked").toArray().length == 0) {
        alert('nothing selected');
        returnfalse;
    }
}

FIDDLE

Solution 2:

you have an error, your input doesn't have ID or CLASS, so add to all of the input radio class='w1' and try the next code:

if ($(".w1 option:selected").length<1)
     alert ('nothing selected');

      <inputtype='radio'class='w1' name='w1' value='2'>2<br>
      <inputtype='radio'class='w1' name='w1' value='3'>3<br>

And in js:

Latest edit:

if ( $(':radio[class=w1]').attr('checked') != 'checked' ) {
    alert('Radio not checked');

}
