PhantomJS - Object


Advertisements


In this chapter, we will look at the four important objects PhantomJS. They are as follows −

  • CookiesEnabled
  • Cookies
  • LibraryPath
  • Version

Let us now discuss each of these in detail.

cookiesEnabled

It tells whether the cookies are enabled or not. It will return true, if yes; otherwise false.

Syntax

Its syntax is as follows −

phantom.cookiesEnabled

Example

cookieenabled.js

phantom.addCookie ({  
   //adding cookie with addcookie property 
   name: 'c1', 
   value: '1', 
   domain: 'localhost' 
}); 

console.log("Cookie Enabled value is : "+phantom.cookiesEnabled); 
phantom.exit();

Output

Command − phantomjs cookieenabled.js

Cookie Enabled value is : true 

Cookies

It helps to add and set cookies to a domain. It returns an object with all the cookies available for the domain.

Syntax

Its syntax is as follows −

phantom.cookies; 

Example

Filename: phantomcookie.js

phantom.addCookie ({ 
   name: 'c1', 
   value: '1', 
   domain: 'localhost' 
}); 
phantom.addCookie ({ 
   name: 'c2', 
   value: '2', 
   domain: 'localhost' 
}); 
phantom.addCookie ({ 
   name: 'c3', 
   value: '3', 
   domain: 'localhost' 
}); 
console.log(JSON.stringify(phantom.cookies)); 
phantom.exit();

Output

Command − phantomjs phantomcookie.js

[{"domain":".localhost","httponly":false,"name":"c3","path":"/","secure":false, " 
value":"3"},{"domain":".localhost","httponly":false,"name":"c2","path":"/","sec u 
re":false,"value":"2"},{"domain":".localhost","httponly":false,"name":"c1","pat h
":"/","secure":false,"value":"1"}]

In the above example, we added some cookies to the localhost domain. We then fetched it using phantom.cookies. It returns an object with all the cookies by using the JSON stringify method to convert the JavaScript object into a string. You can also use foreach to access the name/values of the cookies.

LibraryPath

PhantomJS libraryPath stores the script path to be used by the injectJS method.

Syntax

Its syntax is as follows −

phantom.libraryPath 

Example

Here is an example to find out the version.

var webPage = require('webpage');
var page = webPage.create();

page.open('http://www.tutorialspoint.com/jquery', function(status) {
   if (status === "success") { 
      page.includeJs('http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js ', function() { 
         if (page.injectJs('do.js')) { 
            // returnTitle is a function loaded from our do.js file - see below 
            return returnTitle(); 
         });
         
         console.log(title); 
         phantom.exit(); 
      } 
   } 
});

window.returnTitle = function() { 
   return document.title;
}; 

The above program generates the following output.

Version

It gives the version of the PhantomJS that is running and returns the details in an object. For example: {"major":2,"minor":1,"patch":1}

Syntax

Its syntax is as follows −

phantom.version

Example

Here is an example to find out the version.

var a = phantom.version;
console.log(JSON.stringify(a));
console.log(a.major);
console.log(a.minor);
console.log(a.patch);
phantom.exit();

The above program generates the following output.

{"major":2,"minor":1,"patch":1} 
2 
1 
1

In the above example, we have used console.log to print the version. Currently, we are running on version 2. It returns the object with the details shown in the above code block.
