Hi,

Unfortunately, as far as I can tell on a few minutes' effort, TinyURL
doesn't support cross-origin resource sharing (CORS)[1], and so while
you could do this with Ajax.Request[2]:
new Ajax.Request("http://tinyurl.com/api-create.php?url=http://
www.google.com/", {
method: "GET",
onSuccess: function(response) {
var newUrl = response.responseText;
alert("New URL: " + newUrl);
}
});
...it doesn't work because it fails afoul of the SOP[3].
Apparently you're not the first to want to do this client-side,
because in the course of trying to find out whether TinyURL supported
CORS I ran across a Google AppEngine site[4] that works around this
using JSONP[5]. So you could use that service (if you could find
someone to ask permission from):
function gotTinyURL(data)
{
if (data.ok) {
alert("New URL: " + data.tinyurl);
}
else {
alert("Request failed");
}
}
function getTinyURL(url)
{
var head, script;
head = $$('head')[0];
if (head) {
script = new Element('script', {
type: 'text/javascript',
src: 'http://json-tinyurl.appspot.com/?url=' + url +
"&callback=gotTinyURL"
});
head.appendChild(script);
head.removeChild(script);
}
}
Note that when you call a JSONP service in this way, you are *trusting
that service not to do anything bad* because you're giving them full
access to the page (that's how JSONP works).
