Question

I am trying to figure out, how can I automatically submit a url at the following page

http://www.facebook.com/sharer.php

without actually clicking on the submit button.

Thanks.

Answer 1

You can find that from the page source. There is a form defined…

<form action="/sharer.php" method="get">

and the button is a submit button, which means that when you click the button, the form data is sent as a get request to http://www.facebook.com/sharer.php – in other words, it submits back to itself.

Update – asker wants to know how to submit the form without clicking on the link.

The form is:

<form action="/sharer.php" method="get">
  <input type="text" class="inputtext DOMControl_placeholder" id="share_input" name="u" placeholder="http://" value="http://" title="http://" />
  <input type="hidden" name="appid" value="2309869772" />
  <label class="mrm uiButtonNoText uiButton uiButtonConfirm uiButtonMedium" id="share_submit">
    <input value="Share" type="submit" />
  </label>
</form>

So you need to GET a URL with form data something like the following

http://www.facebook.com/sharer.php?u=your_encoded_url&appid=yourappid
