**getPageContent()**

Signature: getPageContent()

Retrieves current page contents, dealing with exotic other content types than HTML:

getHTML()

Signature: getHTML(\[String selector, Boolean outer\])

Retrieves HTML code from the current page. By default, it outputs the whole page HTML contents:

casper.start('http://www.google.fr/', function() {
    this.echo(this.getHTML());
    });
    casper.run();

casper.start('http://www.google.fr/', function() \{  
this.echo(this.getHTML());  
\});  
casper.run();

You can fetch those contents using:

casper.start('http://www.site.tld/', function() {
    this.echo(this.getHTML('h1#foobar')); // => 'Plop'
    });

The outer argument allows to retrieve the outer HTML contents of the matching element:

casper.start('http://www.site.tld/', function() {
    this.echo(this.getHTML('h1#foobar', true)); // => '<h1 id="foobar">Plop</h1>'
    });

getFormValues()

Signature: getFormValues(String selector)  
New in version 1.0.  
Retrieves a given form all of its field values:  
casper.start('http://www.google.fr/', function() \{  
this.fill('form', \{q: 'plop'\}, false);  
this.echo(this.getFormValues('form').q); // 'plop'  
\});  
casper.run();

getGlobal()  
Signature: getGlobal(String name)  
Retrieves a global variable value within the remote DOM environment by its name. Basically, getGlobal(’foo’)  
will retrieve the value of window.foo from the page:  
casper.start('http://www.google.fr/', function() \{  
this.echo(this.getGlobal('innerWidth')); // 1024  
\});  
casper.run();
