Evaluate in PhantomJS doesn't seem to work

Question

I have a problem with JavaScript magic. When I execute this code:

var page = require('webpage').create(); var url="http://google.com"; page.open(url, function (status){ if (status!== "success") { console.log("Fail to load: "+url) }else{ console.log('1'); page.evaluate(function() { console.log('2'); }); console.log('3'); } phantom.exit(); });

console have only 1 and 3 and no 2. Can anyone say why?

If I paste after my code DOM manipulation example (but it never execute) I have my two. Did I forget something important?

PhantomJS won't log console messages in .evaluate() statements by default. Just include

page.onConsoleMessage = function (msg) { console.log(msg); };

See this page for more details/in-depth example:

From Google Code

Any console message from a web page, including from the code inside evaluate(), will not be displayed by default. To override this behavior, use the onConsoleMessage callback.

If you only want select logs to come through, you can return the value that you'd like to print.

For example:

console.log(page.evaluate(function() { return '2'; });
