I need to write a function that when the button is clicked to see if the checkbox is ticked and that the class name of the li contains 'True'.

So far this is my jQuery:

      $('.multiplechoice_answer .Paragraph').prepend('');
      $('.multiplechoice_wrap').prepend('');


      $('.multiplesubmit').click(function() {
        multipleChoiceCheck();


      });

      var multipleChoiceCheck = function() {
        if($('input:checkbox[name=checkme]').is(':checked') && $('.multiplechoice_answer').hasClass('True')) {
          alert('correct!');
        }

};

Answer

$('.multiplesubmit').click(function () {
  var correctAnswers = $(this).next('ul').children('li').filter(function () {
    return $(this).hasClass('True') && $(this).find('input[type="checkbox"]:checked').length>0;
  });
  if(correctAnswers.length>0) {
    alert('found')
  }
});

As per comments

$('.multiplesubmit').click(function () {
  var correctAnswers = $(this).next('ul').children('li').filter(function () {
    return $(this).hasClass('True') && $(this).find('input[type="checkbox"]:checked').length>0;
  });

  var wrongAnswers = $(this).next('ul').children('li').filter(function () {
    return $(this).hasClass('False') && $(this).find('input[type="checkbox"]:checked').length>0;
  });
  if (correctAnswers.length>0 && wrongAnswers.length<1) {
    alert('found')
  }
});
