i am getting strange error .... like the same prize many times ... better with code ...
var mirarPagina = function() {
console.log("miro pagina")
page.open("mysite.com",function(status){
if (status === "success") {
page.includeJs('http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js', function() {
var total = page.evaluate(function() {
return jQuery("#priceId").text();
});
page.render("precio.jpg")
console.log(total);
setTimeout(function() {
console.log("timeoutttttttt")
mirarPagina();
}, 6000);
});
}else{
console.log("Error abriendo pagina " + status);
setTimeout(function() {
console.log("timeoutttttttt")
mirarPagina();
}, 6000);
}
});
};

it seems to work ok without includejs ..... but with include it multiplies ....
page test:
var page = require('webpage').create();
console.log('The default user agent is ' + page.settings.userAgent);
page.settings.userAgent = 'SpecialAgent';
var mirarPagina = function() { page.open('http://www.httpuseragent.org', function(status) {
if (status !== 'success') {
console.log('Unable to access network');
setTimeout(function() {
mirarPagina()
}
,3000);
} else {
page.includeJs('http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js', function() {
console.log("despues de incluirlo miro precio")
var total = page.evaluate(function() {
return jQuery("#myagent").text();
});
console.log(total);
setTimeout(function() {
mirarPagina()
}
,3000);
});
}
});
}
setTimeout(function() {
mirarPagina()
}
,3000);

For what it's worth, I've run into a similiar problem when including jQuery in a page that was already including it.
Now I test if jQuery was previsouly defined and only include it if really needed (this leaves a problem where some functionality may not be present on older versions of the lib ...) --

It is not the jquery ... it fails too with sizzle ....
var page = require('webpage').create();
console.log('The default user agent is ' + page.settings.userAgent);
page.settings.userAgent = 'SpecialAgent';
page.onConsoleMessage = function(msg) {
console.log(msg);
};
page.onError = function(msg, trace) {
var msgStack = ['ERROR: ' + msg];
if (trace && trace.length) {
msgStack.push('TRACE:');
trace.forEach(function(t) {
msgStack.push(' -> ' + t.file + ': ' + t.line + (t.function ? ' (in function "' + t.function +'")' : ''));
});
}
console.error(msgStack.join('\n'));
};
var i= 0;
var tiempo = function() {
i=i+1;
console.log("tiempo "+i)
setTimeout(mirarPagina(),16000);
}
var mirarPagina = function() { page.open('http://www.httpuseragent.org', function(status) {
if (status !== 'success') {
console.log('Unable to access network');
tiempo()
} else {
console.log("antes de injectar")
if (page.injectJs('/var/lib/openshift/560264730c1e667ade00007d/app-root/data/sizzle.js')) {
console.log("despues de incluirlo miro precio")
var total = page.evaluate(function() {
return Sizzle.getText(Sizzle("myagent"))
});
console.log(total);
tiempo();
} else {
console.log("que pasoooooooo")
}
}
});
}
tiempo()
with this script when the network starts to fail (testing on openshift, perhaps it detects it is an attack to a server) it displays very fast the console.log("tiempo") and doesnt wait the timeout .... why? i dont know :(
