If Statement Radio Button Help?

If Statement Radio Button Help?

The function below hides and shows the rest of my form fields (when I don't use the if statement).  I wanted to try to make an if statement so that when I reload the page, I don't have to reselect the radio button when it is not null.  I want to have an if statement that says, if the radio buttons are null, hide the form fields.  If it is not null, just maintain the current state. Unfortunately, I couldn't get the function below to work. 

  1. $(function (){

    if ($('input.radioalign[value=""]')) {

     $('fieldset[id$=Form]').hide());
     
    }

    $('input[name=selector]').click(function() {
          var id = '#' + this.id.replace(/Button/, 'Form');
          $('fieldset[id$=Form]').not(id).hide();
          $(id).show();
    });

    });













Here is are the corresponding buttons in HTML.

  1. <p>
                   
           <label for="selector" class="leftcolalign">What am I? *</label>
                   
            <input id="entButton" class="radioalign" type="radio" name="selector" checked="checked" value="Entrepreneur"<?php print $entrepreneur; ?>>
                   
            <label for="entrepreneur" id="entrepreneur">Entrepreneur</label>

            <input id="invButton" class="radioalign" type="radio" name="selector" checked="checked" value="Investor"<?php print $investor; ?>>
                   
            <label for="investor" id="investor">Investor</label>
               
     </p>
