- # Returns a link to a remote action defined by <tt>$options['url']</tt>
- # (using the url_for() format) that's called in the background using
- # XMLHttpRequest. The result of that request can then be inserted into a
- # DOM object whose id can be specified with <tt>$options['update']</tt>.
- # Usually, the result would be a partial prepared by the controller with
- # render_partial.
- #
- # Examples:
- # link_to_remote("Delete this post", array("update" => "posts", array("url" => array(":action" => "destroy", ":id" => $post->id)))
- # link_to_remote(image_tag("refresh"), array("update" => "emails", "url" => array(":action" => "list_emails")))
- # link_to_remote(image_tag("refresh"), array("update" => "emails", "url" => "/posts/list_emails"))
- #
- # You can also specify a hash for <tt>$options['update']</tt> to allow for
- # easy redirection of output to an other DOM element if a server-side error occurs:
- #
- # Example:
- # link_to_remote("Delete this post", array(
- # "url" => array(":action" => "destroy", ":id" => $post->id),
- # "update" => array("success" => "posts", "failure" => "error")
- # ))
- #
- # Optionally, you can use the <tt>$options['position']</tt> parameter to influence
- # how the target DOM element is updated. It must be one of
- # <tt>before</tt>, <tt>top</tt>, <tt>bottom</tt>, or <tt>after</tt>.
- #
- # By default, these remote requests are processed asynchronous during
- # which various JavaScript callbacks can be triggered (for progress indicators and
- # the likes). All callbacks get access to the <tt>request</tt> object,
- # which holds the underlying XMLHttpRequest.
- #
- # To access the server response, use <tt>request.responseText</tt>, to
- # find out the HTTP status, use <tt>request.status</tt>.
- #
- # Example:
- # link_to_remote($word, array(
- # "url" => array(":action" => "undo", "n" => $word_counter ),
- # "complete" => "undoRequestCompleted(request)"))
- #
- # The callbacks that may be specified are (in order):
- #
- # <tt>loading</tt>:: Called when the remote document is being
- # loaded with data by the browser.
- # <tt>loaded</tt>:: Called when the browser has finished loading
- # the remote document.
- # <tt>interactive</tt>:: Called when the user can interact with the
- # remote document, even though it has not
- # finished loading.
- # <tt>success</tt>:: Called when the XMLHttpRequest is completed,
- # and the HTTP status code is in the 2XX range.
- # <tt>failure</tt>:: Called when the XMLHttpRequest is completed,
- # and the HTTP status code is not in the 2XX
- # range.
- # <tt>complete</tt>:: Called when the XMLHttpRequest is complete
- # (fires after success/failure if they are present).,
- #
- # You can further refine <tt>success</tt> and <tt>failure</tt> by adding additional
- # callbacks for specific status codes:
- #
- # Example:
- # link_to_remote($word,
- # "url" => array(":action" => "action"),
- # "failure" => "alert('HTTP Error ' + request.status + '!')")
- #
- # A status code callback overrides the success/failure handlers if present.
- #
- # If you for some reason or another need synchronous processing (that'll
- # block the browser while the request is happening), you can specify
- # <tt>$options['type'] = "synchronous"</tt>.
- #
- # You can customize further browser side call logic by passing
- # in JavaScript code snippets via some optional parameters. In
- # their order of use these are:
- #
- # <tt>confirm</tt>:: Adds confirmation dialog.
- # <tt>condition</tt>:: Perform remote request conditionally
- # by this expression. Use this to
- # describe browser-side conditions when
- # request should not be initiated.
- # <tt>before</tt>:: Called before request is initiated.
- # <tt>after</tt>:: Called immediately after request was
- # initiated and before <tt>:loading</tt>.
- # <tt>submit</tt>:: Specifies the DOM element ID that's used
- # as the parent of the form elements. By
- # default this is the current form, but
- # it could just as well be the ID of a
- # table row or any other DOM element.
