在jQuery中使用ajax - 不接受url

Question

I'm trying to build an ajax request that will eventually allow users to sort a list by clicking buttons next to each item. Here's what I have so far:

upLinks.on('click', function(e) {
  var link;
  e.preventDefault();
  link = $(this)[0];
  console.log(link.pathname);
  $.ajax({
    type: 'PUT',
    url: link.pathname
  });
  return false;
});

console.log(link.pathname) logs out /projects/11/project_items/104/sort to the console, as expected. However, the ajax request returns an error:

PUT http://localhost:3000/projects/11 400 (Bad Request)

Looking at the server logs, it is in fact going to /projects/11 , not /projects/11/project_items/104/sort for some reason. According to the jQuery docs, /projects/11 would be the default parameter for ajax in this case, because that's the route of the current page. Which leads me to believe it's ignoring the url parameter altogether.

If I change HTTP method type to GET , the ajax runs as expected. Is there some reason /projects/11/project_items/104/sort is not an acceptable url for a PUT request? I thought that because I'm updating data (with the new position) a PUT request would be the most logical option.

Just a note, if you're using an IIS webserver and the jquery PUT or DELETE requests are returning 404 errors, you will need to enable these verbs in IIS. I've found this to be a good resource: http://geekswithblogs.net/michelotti/archive/2011/05/28/resolve-404-in-iis-express-for-put-and-delete-verbs.aspx

"The type of request to make ("POST" or "GET"), default is "GET". Note: Other HTTP request methods, such as PUT and DELETE, can also be used here, but they are not supported by all browsers." from: http://api.jquery.com/jQuery.ajax/#options
