How can I paste text to a pastebin site through API's HTTP POST using a bookmarklet? - bookmarklet

Question

I want to paste some text to a pastebin site through the site's API.
As I have figured out (I have limited knowledge of programming) I need two things: First to process the selected text and then to post it via HTTP POST to the pastebin site.
I tried to do this...
javascript:'<body%20onload="document.forms[0].submit()"><form%20method="post"%20action="http://sprunge.us"><input%20type="hidden"%20name="sprunge"%20value="+ document.getSelection() +"></form>'
....which (you guessed it!) returns to me EVERY TIME a page in which the selected text being "+ document.getSelection() +".
Any help?

You have to make a form programmatically, add the fields required and then post -- all in JavaScript.
Here is an example -- you will at least have to change the URL and the fieldname:
<a href="
javascript:(function(){
var myform = document.createElement('form');
myform.method='post';
/* change this URL: */
myform.action='http://my-example-pastebin.com/submit.php';
/* The goodies go here: */
var myin=document.createElement('input');
/* Change the fieldname here: */
myin.setAttribute('name','fieldname_for_pasted_text');
myin.setAttribute('value',document.getSelection());
myform.appendChild(myin);
/* If you need another field for username etc: */
myin=document.createElement('input');
myin.setAttribute('name','some_field_1');
myin.setAttribute('value','some_field_value_1');
myform.appendChild(myin);
myform.submit();
})()
">Bookmarklet for posting selected text to an online pastebin</a>
The above compacted without comments and linebreaks:
Bookmarklet for posting selected text to an online pastebin
I'm not familiar with sprunge.us, but if you've got the URL and fieldname right in your example, you could get this to work by search-replace:
http://my-example-pastebin.com/submit.php → http://sprunge.us/
fieldname_for_pasted_text → sprunge
You should also remove the second field (some_field_1, somefield_value_1) included in my example.
