I'am visiting certain websites with phantomjs. Is it possible to run functions from sites environment in page.evaluate method? Can you provide and example of correct usage.

1Psssssst... You should try using Puppeteer instead of Phantom: github.com/GoogleChrome/puppeteerMax Baldwin– Max Baldwin2018-04-17 14:40:50 +00:00Commented Apr 17, 2018 at 14:40

Yes, of course it is possible. You just call the site function inside of page.evaluate. Consider the example:
example.com html
<html>
<head>
</head>
<body style="background-color: white">
<p>A page</p>
<script>
function makeRed() {
document.body.style.backgroundColor = "red";
}
</script>
</body>
</html>
PhantomJS script
var page = require('webpage').create();
page.viewportSize = { width: 600, height: 300 };
page.open('http://example.com', function() {
page.evaluate(function(){
makeRed();
});
setTimeout(function(){
page.render('red.png');
phantom.exit();
}, 1000);
});
Result:
