# Casper.js

Casper is a navigation utility for [PhantomJS](http://www.phantomjs.org/).

More documentation to come soon, I swear. If you just can't wait, here's a sample script:

phantom.injectJs('casper.js');

// User defined functions
function q() {
document.querySelector('input[name="q"]').setAttribute('value', '%term%');
document.querySelector('form[name="f"]').submit();
}

function getLinks() {
return Array.prototype.map.call(document.querySelectorAll('h3.r a'), function(e) {
return e.getAttribute('href');
});
}

// Casper suite
var links = [];
var casper = new phantom.Casper()
.start('http://google.fr/')
.thenEvaluate(q, {
term: 'casper',
})
.then(function(self) {
links = self.evaluate(getLinks);
})
.thenEvaluate(q, {
term: 'homer',
})
.then(function(self) {
links = links.concat(self.evaluate(getLinks));
})
.run(function(self) {
self.echo(JSON.stringify({
result: self.result,
links: links
}, null, ' '));
self.exit();
})
;

Run it:
