Passing Global Variable from One Evaluated Page to Another

So I have some code and I would like to pass a variable outside so I can evaluate another page and inject the code from the previous page.

I'm not an expert here and I'm just not grasping the concept. Can anyone help me understand what I'm doing wrong?

var scheduleArray = [];

//blah blah removed code...everything works up to this point

casper.thenEvaluate(function(scheduleArray){

    console.log("##Your schedule is " + document.querySelector('form + div table').textContent );
    var rawSchedule = document.querySelector('form + div table').textContent;
    scheduleArray = rawSchedule.match(/((Monday)|(Tuesday)|(Wednesday)|(Thursday)|(Friday)|(Saturday)|(Sunday))([0-9]{1,2}\/[0-9]{1,2}\/[0-9]{4})((5)|(C6)|(6)|(7H)|(7F)|(715)|(8F)|(10F)|(12F)|(1F)|(2H)|(C2)|(2))/gi);
    console.log("##scheduleArray");
    console.log(scheduleArray);

    for (i=0;i<scheduleArray.length;i++){
        console.log(scheduleArray[i]);
    }


},scheduleArray);

casper.then(function(scheduleArray){
    console.log("##scheduleArray");
//This loop contains no data
    for (i=0;i<scheduleArray.length;i++){
            console.log(scheduleArray[i]);
        }
},scheduleArray);

I write a small sample code for you to illustrate how to passing result between evaluate and the casper script:

var casper = require('casper').create({
    verbose: true,
    logLevel: 'debug'
});

var array = []

casper.start('http://www.ecma-international.org/memento/TC39.htm');

casper.then(function() {
    array = casper.evaluate(function () {
        var nodes = document.querySelectorAll('a')
        var result = Array.prototype.map.call(nodes, function (div) {
            return div.href
        })
        return result
    });
});

casper.then(function () {
    casper.echo(array.length);
    casper.echo(array.join("\n"))
})

casper.run()

Output:

... ignore some lines

So, come to your code:

1. The change of the argument of evaluate doesn't take that change to your global variable. That is to say, what ever you do to scheduleArray inside evaluate, the global variable scheduleArray remains the same.

2. Inside evaluate, you should use console.log to log, but outside the evaluate, you should use casper.echo.
