I have two urls X and Y. When casperjs is on X page, it have to call Y page and after getting the response it should continue.
casper.start("X URL",function() {
var casper2 = require('casper').create();
casper2.start();
casper2.open("Y URL", function() {
RESPONSE
});
casper2.run();
}).then... >> It have to wait for response.
How can i do?

You have to use casper.then after the click. Here is some code:
var x = require('casper').selectXPath;
var url = 'http://stackoverflow.com/';
var casper = require('casper').create({
verbose: false,
logLevel: 'debug'
});
casper.test.comment('Starting Testing');
casper.start(url, function() {
//console.log(this.getCurrentUrl());
this.test.assert(
this.getCurrentUrl() === url, 'url is the one expected'
);
this.test.assertHttpStatus(200, + 'site is up');
casper.waitForSelector(x("//a[normalize-space(text())='Questions']"),
function success() {
this.test.assertExists(x("//a[normalize-space(text())='Questions']"));
this.click(x("//a[normalize-space(text())='Questions']"));
},
function fail() {
this.test.assertExists(x("//a[normalize-space(text())='Questions']"));
}
);
casper.then(function() {
//console.log(this.getCurrentUrl());
this.test.assertUrlMatches("http://stackoverflow.com/questions",
"clicked through to questions page");
});
casper.thenOpen('http://reddit.com', function() {
this.test.assertUrlMatches("http://www.reddit.com/",
"On Reddit");
});
});
casper.run(function() {
this.echo('finished');
this.exit();
});
Basically it goes to stackoverflow.com, waits until the Questions button is loaded, clicks on it and checks whether the redirected url is valid.
You can uncomment //console.log(this.getCurrentUrl()); if you want to see the specific url.
Now lets say you want to go to to an entirely new page, we can do use thenOpen api.
