jquery - Quiz App: Buttons in javascript are not functioning -

currently i'm working on quiz in multiple choice format. however, when click on button, doesn't work!

here's full code of mini quiz https://github.com/selvabalasingam/typequiz/blob/master/js/app.js

but i'm sure problem lies between lines 89-103 (i've pasted portion of code below)

$('button.choice').click(function(e) {     var choice = $(e.target).text();     var question = quiz.getcurrentquestion();      // check if answer right , update question number , score     if (question.answer == choice) {         gettotalcorrect = $('.questioncount').text(gettotalcorrect+1);          getscore = $('.scorepercentage').text(getscore);     }     else {         gettotalcorrect = $('.questioncount').text(gettotalcorrect+0);          getscore = $('.scorepercentage').text(getscore);     }     // go next question     getnextquestion(); }); 

can tell problem is? there way fix this?

if take @ console, you'll see gettotalcorrect undefined. because gettotalcorrect method attached scope of quiz object, you're trying access globally.

you can change this:

if (question.answer == choice) {     gettotalcorrect = $('.questioncount').text(gettotalcorrect+1);      getscore = $('.scorepercentage').text(getscore); } else {     gettotalcorrect = $('.questioncount').text(gettotalcorrect+0);      getscore = $('.scorepercentage').text(getscore); } getnextquestion(); 

to:

question.answer = choice;    // pass user's choice question object $('.questioncount').text(quiz.gettotalcorrect()); $('.scorepercentage').text(quiz.getscore()); quiz.getnextquestion();    // load next question rendertext(quiz.getcurrentquestion());    // render new font 

it looks rendertext indefinitely call itself:

var rendertext = function(question) {     $('.text').css('font-family', question.correctchoice);     rendertext(quiz.getcurrentquestion());   // infinite recursion call }; 

instead, call rendertext when page loads, so:

var rendertext = function(question) {     $('.text').css('font-family', question.correctchoice); };  rendertext(quiz.getcurrentquestion());
