Pass additional parameters to jQuery each() callback

You should be able to create a reference to your survey before you iterate over the questions.

function Survey() {
    this.questions = new Array();
    var survey = this;
    $('.question').each(function(i) {
        survey.questions.push(new Question(this));
    });
}

function Question(element) {
    this.element = $(element);
}

var survey = new Survey();

$.each(survey.questions, function() {
    $("ul").append("<li>" + this.element.text() + "</li>");
});
