CodeIgniter

I am unable to use the following code into the view of CI.

<script>

  var options = {

    onFail: function() {
      alert( $myform.getInvalid().length +' invalid fields.' )
    },

    inputs: {
      'password': {
        filters: 'required pass',
      },
      'username': {
        filters: 'required username',
        data: {
          //ajax: { url:'validate.php' }
        }
      },
      'file': {
        filters: 'extension',
        data: { extension: ['jpg'] }
      },

      'comments': {
        filters: 'min max',
        data: { min: 50, max: 200 }
      },
      'states': {
        filters: 'exclude',
        data: { exclude: ['default'] },
        errors : {
          exclude: 'Select a State.'
        }
      },
      'langs[]': {
        filters: 'min max',
        data: { min: 2, max: 3 },
        errors: {
          min: 'Check at least 2 options.',
          max: 'No more than 3 options allowed.'
        }
      }
    }
  };
  var $myform = $('#my-form').idealforms(options).data('idealforms');

  $('#reset').click(function(){ $myform.reset().fresh().focusFirst() });
  $myform.focusFirst();

</script>

So i want the way to use javascript and jquery code for the CI view .
