我可以在自己网站的外部网站上填写表格吗？

Question

I am not sure whether this is possible or not, but if it is, I need to know where to start at least. I want to fill the form on the site I do not own, using a field on the site I do own.

Specifically this computer game site http://www.g2a.com/ , and the search form there which is

<input type="text" class="mp-h-main ui-autocomplete-input" id="product-autocomplete" placeholder="Search a game" data-rel="active" autocomplete="off" state="closed">

It seems to be Ajax or jQuery loaded, and there seems to be no regular search function on the site. Is there a good known way, or do I stand little chance in this case?

Kind regards, John

Sniff the form post content using something like live http headers for firefox and emulate it with php curl , ie:

<?php
$productName = rawurlencode("DOOM STEAM CD-KEY PREORDER GLOBAL");
$url = "https://www.g2a.com/lucene/search/quick?jsoncallback=jQuery111005943281338131983_1462669099509&phrase=$productName&isWholesale=false&cn=&skip=28837%2C28838%2C28847%2C28849%2C28852%2C28856%2C28857%2C28858%2C28859%2C28860%2C28861%2C28862%2C28863%2C28867%2C28868%2C29472%2C29473%2C29474%2C33104&start=0&rows=5&_=1462669099513";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(

$response = curl_exec($ch);
echo $response;
curl_close ($ch);
