|
||||
* Uploading file using rails.js
|
||||
* =============================
|
||||
*
|
||||
* By default, browsers do not allow files to be uploaded via AJAX. As a result, if there are any non-blank file fields
|
||||
* in the remote form, this adapter aborts the AJAX submission and allows the form to submit through standard means.
|
||||
*
|
||||
* The `ajax:aborted:file` event allows you to bind your own handler to process the form submission however you wish.
|
||||
*
|
||||
* Ex:
|
||||
* $('form').live('ajax:aborted:file', function(event, elements){
|
||||
* // Implement own remote file-transfer handler here for non-blank file inputs passed in `elements`.
|
||||
* // Returning false in this handler tells rails.js to disallow standard form submission
|
||||
* return false;
|
||||
* });
|
||||
*
|
||||
* The `ajax:aborted:file` event is fired when a file-type input is detected with a non-blank value.
|
||||
*
|
||||
* Third-party tools can use this hook to detect when an AJAX file upload is attempted, and then use
|
||||
* techniques like the iframe method to upload the file instead.
|
||||
*
|
||||
* Required fields in rails.js
|
||||
* ===========================
|
||||
*
|
||||
* If any blank required inputs (required="required") are detected in the remote form, the whole form submission
|
||||
* is canceled. Note that this is unlike file inputs, which still allow standard (non-AJAX) form submission.
|
||||
*
|
||||
* The `ajax:aborted:required` event allows you to bind your own handler to inform the user of blank required inputs.
|
||||
*
|
||||
* !! Note that Opera does not fire the form's submit event if there are blank required inputs, so this event may never
|
||||
* get fired in Opera. This event is what causes other browsers to exhibit the same submit-aborting behavior.
|
||||
*
|
||||
* Ex:
|
||||
* $('form').live('ajax:aborted:required', function(event, elements){
|
||||
* // Returning false in this handler tells rails.js to submit the form anyway.
|
||||
* // The blank required inputs are passed to this function in `elements`.
|
||||
* return ! confirm("Would you like to submit the form with missing info?");
|
||||
* });
