如何将jQuery [each]循环中的JavaScript存储到php变量中

Question

I am [successfully] storing a snippet of jQuery inside a php variable, with values inside the snippet being populated by php script like so:

...//collect necessary variables

$script = "
  <script type='text/javascript'>
    (function($) {
      analytics.identity('" . $cid . "', {
        created: '" . $created . "',
        email: '" . $email . "',
        ...: '" . $whatever . "'
      });
    })(jQuery);
  </script>
";

return $script;

I can also [successfully] get the name attribute of all forms on the page like so:

 <script type='text/javascript'>
    (function($) {
      $('form').each(function() {
        var formname = $( this ).attr('name');
        if(formname !== undefined) {
          console.log(index + ':' + encodeURIComponent(formname));
        };
      });
    })(Jquery);
</script>

The problem I'm having (maybe obviously) is the lack of experience with javascript to know how to incorporate the two so my $script would look like so:

$script = "
  <script type='text/javascript'>
    (function($) {
      analytics.identity('" . $cid . "', {
        created: '" . $created . "',
        email: '" . $email . "',
        ...: '" . $whatever . "'
      });
      analytics.trackForm($('form[name="formname1"]'),'Form Submitted', {
        lead: formname
      });
      analytics.trackForm($('form[name="formname2"]'),'Form Submitted', {
        lead: formname
      });
      ...//(n) number of form names
    })(jQuery);
  </script>
";

Latest script added directly to the footer:

<script type="text/javascript">
  (function($) {
   $('form').each(function() {
    var formname = $(this).attr('name');
    if( formname !== undefined) {
      console.log( formname );
      var forms = $('form[name="' + formname + '"]');
      var trackforms = analytics.trackForm(forms, 'Submitted Optin Form', { leadmagnet: "'" + formname + '"' });
      return trackforms;
    }
   });
  })(jQuery);
</script>

Console.log outputs the one form currently on the page, and if I add another, it outputs that correctly also, but the rest of the code is simply written as is and I'm not getting it.

Thanks again.

document.write(...) is adding the string to the document not to the script.

You need to return the functions you want.

$script = "
  <script type='text/javascript'>
    (function($) {
      analytics.identify('" . $ifs_id . "', {
        created: '" . $created . "',
        email: '" . $email . "',
        firstName: '" . $first_name . "',
        leadsource: '" . $lead_source ."'
      });
      $('form').each(function( index ) {
        var formname = $( this ).attr('name');
        if( formname !== undefined) {
          //console.log( index + ':' + formname );
          var forms = $('form[name=\"+formname+\"]);
          var trackform = analytics.trackForm(forms, 'Submitted Opt In Form', {
             leadmagnet : $( this ).attr('name')
           });
          return trackform;

        }
      });
    })(jQuery);
   </script>
";

return $script;
