define page evaluate outside of page open in phantomjs

Question

in the basic example of open a web page with phantomjs we use below code for open web and evaluate when page open complete in a function .

var page = require('webpage').create(); page.open('http://www.sample.com', function() { page.includeJs("http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js", function() { page.evaluate(function() { console.log(document.title); }); phantom.exit() }); });

is any way that let us define page.evaluate in a function out side of page.open callback function for call it any time we need and no just after page open

not sure what exactly do you mean, but from what I've understood from your example this could help maybe:

var page = require('webpage').create(); // document is already initialized document.title = 'internal call'; page.onConsoleMessage = function (msg, lineNum, sourceId) { console.log('PAGE\'S CONSOLE: ' + msg + ' (from line #' + lineNum + ' in "' + sourceId + '")'); }; var func = function () { console.log('Title: ', document.title); } // calling outside of the page.open: func(); page.open('http://google.com/', function () { page.includeJs("http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js", function () { // calling inside: page.evaluate(func); page.close(); phantom.exit(0); }); });

Also there is a Note for page.evaluate function about arguments and closures
