JQuery include in phantomjs is not working - phantomjs

Question

My code is:
var url = 'https://search.yahoo.com/',
page = new WebPage(),
fs = require('fs');
page.settings.userAgent = 'Mozilla/5.0 (platform; rv:geckoversion) Gecko/geckotrail appname/appversion';
page.onConsoleMessage = function (msg) {
console.log(msg);
};
page.open(url, function(status) {
if (status !== 'success')
{
console.log('Unable to access network');
phantom.exit();
return;
}
else
{
page.includeJs("https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js", function()
{
page.evaluate(function()
{
$('#yschsp').val("ask question");
$(".sbb").click();
});
page.onLoadFinished = function(status) {
var content = page.content;
fs.write('1.html', content, 'w');
console.log($('#link-1').val());
phantom.exit();
};
});
}
});
JQuery works perfect in page.evaluate but does not work in page.onLoadFinished. I get an error
Can't get variable: $
That means that in function page.onLoadFinished jquery is not working. But I can not understand why?

Answer 1

Since jQuery is loaded into the page context, you can only use there. The only function that interfaces with the page context is evaluate (and the other evaluate functions).
So this line
console.log($('#link-1').val());
must be inside of an evaluate callback. Since you have a page.onConsoleMessage event handler you will receive the console message from the page context.
The other thing is that adding an page.onLoadFinished event handler after the page has loaded isn't doing anything useful. You can remove the handler surrounding your code since the page load is finished when the page.open callback is called.
If #link-1 is not yet loaded, you should either log the value after a static timeout (setTimeout) or use waitFor.
