Wait for URL change in Casper.js?

Question

There is a waitForUrl() functionality in Casper.js, but is it possible to waitForUrlChange() in Casper.js?

I mean detecting a change in this.getCurrentUrl() value. I can't predict the new url value. It can be anything.

Answer 1

There's an event handler for it

casper.on('url.changed',function(url) {
casper.echo(url);
});

Here's the documentation for it: http://casperjs.readthedocs.org/en/latest/events-filters.html#url-changed

However, as Artjom B. mentioned, this won't cover all cases that a function extension would handle. It's only really appropriate when you don't need it as part of the control flow, but just want to reactively scrape some values when it happens.
