Add two parameters in function into "then" protractor

Question

It is quite clear. I have an array with some links and I want to build a loopto try all of them, but the problem is that link is always 3. It means that it read the last number in my array. Why? How can I fix it?

var categories = ['1','2','3'];
for( var i = 0; i < categories.length; i++ ) {
    var link = '/'+categories[i];
    browser.get(link);
    browser.sleep(2000);
    browser.driver.getCurrentUrl().then( function(url) {
        expect(url).toMatch(link);
    });
}

and I have list of divs and I want to read randomly infos from them. So I made the following

chosenOffer         = Math.floor( (Math.random() * count ) + 1);
offer               = element.all( by.className('offer')).get( chosenOffer );

But it shows always error message chosenOffer object...

This is a classic closure problem that is described in detail in:

• Using protractor with loops

In your case, just let expect() resolve the promise:

var categories = ['1','2','3'];

for (var i = 0; i < categories.length; i++) {
    var link = '/' + categories[i];
    browser.get(link);
    browser.sleep(2000);

    expect(browser.driver.getCurrentUrl()).toMatch(link);
}
