字符串来自Google Books API json的所有标题

Question

我希望从Google图书馆的书架中获取所有标题，并生成一系列以逗号分隔的标题。这是我的尝试：

var allTitles = [];

$.getJSON("https://www.googleapis.com/books/v1/users/115939388709512616120/bookshelves/1004/volumes?key=MYAPIKEY",function(data){

     $.each(data.items, function (i, item) {

         allTitles.push(data.items[0].volumeInfo.title);

  });

var newTitleString = allTitles.join(', ');
    alert(newTitleString);
