使用带有ajax的simple_html_dom [重复]

I'm doing the Parser of a page with the 'simple_html_dom' library however not got success to parse an html whose content is obtained through ajax. is there any way around this?

PHP Code:

<?php
require_once '../library/Simple_HTML_DOM/simple_html_dom.php';

// Create DOM from URL or file
$html = file_get_html('http://www.playnow3dgames.com/genre.php?id=sports');

// Find all images 
foreach($html->find('img') as $element){
echo $element->src . '<br>';
}
?>

Only prints the images on the edges and top (html native) and Is not parsed the center images (using ajax).

</div>

try with this

<?php
require_once '../library/Simple_HTML_DOM/simple_html_dom.php';

// Create DOM from URL or file
$html = file_get_html('http://www.playnow3dgames.com/listing.php?genre=sports&order=date');

// Find all images 
foreach($html->find('img') as $element){
    echo $element->src . '<br>';
}
?>

=== UPDATE ====

actualy, this a iframe, it is not ajax. in center of http://www.playnow3dgames.com/genre.php?id=sports is frame: http://www.playnow3dgames.com/listing.php?genre=sports&order=date

you can see struct of url:

http://www.playnow3dgames.com/listing.php?genre=sports&order=date

at here: genre=sports

this is real url: http://www.playnow3dgames.com/genre.php?id=sports

you will see match of id=sports with genre=sports

to get for every pages, you only need change genre=genre_name. for example:

http://www.playnow3dgames.com/genre.php?id=strategy

the main frame will be:

www.playnow3dgames.com/listing.php?genre=strategy&order=date

if you want to get page 1,2,3..., you need add page=page_number. for example: get page 2 of

http://www.playnow3dgames.com/genre.php?id=strategy

url will be:

http://www.playnow3dgames.com/listing.php?genre=strategy&page=2&order=date
