Ajax call from Bookmarklet

Question

I am trying to create a bookmarklet that, upon clicking, would request some information from the user (a url and a couple other fields in this case) and then send that data

Answer 1

You can set a bookmarklet by create a bookmark and add that piece of code below in location, but, according to same origin policy limitation, that will only work when the current tab is on the same location, here www.google.com.

If I've understand well your needs, that should be ok for your problem.

var request = new XMLHttpRequest();
request.open("GET", "http://www.google.com", true);
request.onreadystatechange = function() {
  var done = 4, ok = 200;
  if (request.readyState == done && request.status == ok) {
    if (request.responseText) {
      alert(request.responseText);
    }
  }
};
request.send(null);

I don't know if POST would work.

Answer 2

You won't be able to do a post, but a GET will work fine. If you're using something like jQuery, it will simply create a script tag with a src URL which would send the data you are looking to submit.

You will have to return JSON style data.

See: http://docs.jquery.com/Ajax/jQuery.getJSON

Alternatively, your bookmarklet could create an iframe on the page, and that could do you work of submitting the data (you could use post then) if you weren't looking to communicate between the iframe and the page itself, but instead just use user input to submit.
