/**
|
|
* Returns link to remote action
|
|
*
|
|
* Returns a link to a remote action defined by <i>options[url]</i>
|
|
* (using the url() 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 <i>options[update]</i>.
|
|
*
|
|
* Examples:
|
|
* <code>
|
|
* link("Delete this post",
|
|
* array("update" => "posts", "url" => "delete/{$postid->id}"));
|
|
* link(imageTag("refresh"),
|
|
* array("update" => "emails", "url" => "list_emails" ));
|
|
* </code>
|
|
*
|
|
* By default, these remote requests are processed asynchronous during
|
|
* which various callbacks can be triggered (for progress indicators and
|
|
* the likes).
|
|
*
|
|
* Example:
|
|
* <code>
|
|
* link (word,
|
|
* array("url" => "undo", "n" => word_counter),
|
|
* array("complete" => "undoRequestCompleted(request)"));
|
|
* </code>
|
|
*
|
|
* The callbacks that may be specified are:
|
|
*
|
|
* - <i>loading</i>:: Called when the remote document is being
|
|
* loaded with data by the browser.
|
|
* - <i>loaded</i>:: Called when the browser has finished loading
|
|
* the remote document.
|
|
* - <i>interactive</i>:: Called when the user can interact with the
|
|
* remote document, even though it has not
|
|
* finished loading.
|
|
* - <i>complete</i>:: Called when the XMLHttpRequest is complete.
|
|
*
|
|
* If you for some reason or another need synchronous processing (that'll
|
|
* block the browser while the request is happening), you can specify
|
|
* <i>options[type] = synchronous</i>.
|
|
*
|
|
* 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:
|
|
*
|
|
* - <i>confirm</i>:: Adds confirmation dialog.
|
|
* -<i>condition</i>:: Perform remote request conditionally
|
|
* by this expression. Use this to
|
|
* describe browser-side conditions when
|
|
* request should not be initiated.
|
|
* - <i>before</i>:: Called before request is initiated.
|
|
* - <i>after</i>:: Called immediately after request was
|
|
* initiated and before <i>loading</i>.
|
