An example PhantomJS script for pulling class data from a schedule webpage.

classes.js

const page = require("webpage").create();
page.open("https://classes.cornell.edu/shared/schedule/SP17/f2447538c565d8b0821840d825a50430", function(status) {
    console.log("Loaded with status " + status);
    if (status == "success") {
        var doc = page.evaluate(function(parse) {
            parse(document);
        }, parse);
        phantom.exit();
    }
});

page.onConsoleMessage = function(msg) {
    console.log(msg);
};

function parse(document) {
    var days = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday'];
    var x = document.getElementsByClassName("fc-event-container");
    for (var i = 0; i < x.length; i++) {
        var tempCol = x[i];
        if ((' ' + tempCol.className + ' ').indexOf(' ' + "fc-helper-container" + ' ') == -1) {
            var y = x[i].getElementsByClassName("fc-content");
            console.log(days.shift());
            for (var j = 0; j < y.length; j++) {
                var text = y[j].innerText;
                console.log(text);
            }
        }
