by the following rules:
1) An initial dialog or panel load can take either HTML or JSON, but
the mime type must accurately reflect its payload.
2) dialog form submits can handle a pure HTML response, but the mime
type must also be correct. This properly resolves the problem
where the reauth code gets a JSON response first from the reauth
code, and then an HTML response when you reauth and continue on to
a given form -- try it out with Admin > Settings > Advanced.
3) All JSON replies must set the mime type correctly. The json::reply
convenience function does this for us.
4) By default, any HTML content sent back in the JSON response should be
in the "html" field, no longer the "form" field.
The combination of these allows us to stop doing boilerplate code like
this in our controllers:
// Print our view, JSON encoded
json::reply(array("form" => (string) $view));
instead, controllers can just return HTML, eg:
// Print our view
print $view;
That's much more intuitive for developers.
When load a file is uploaded using a dialog box and the jquery plugin ajaxForm, the ajaxForm plugin uses an hidden iFrame element to send the multi-part
form and this is where the response goes. The ajaxForm plugin then retrieves the document body and parses the result as a json string. If the file uploads
properly everything is fine, but if it fails Gallery3 return the input form with the the error fields highlighted as part of the json response. As this
response is returned to a hidden iframe, the browser attempts to manipulate it and all hell breaks loose. We lose the trailing brace, we start getting
escaping of form tags. When the ajaxForm plugin retrieves the iFrame body its no longer a valid json frame and the parsing fails and the user sees no
indication that it failed.
and have some basic namespacing:
showMessage --> gallery_show_message
vAlign --> gallery_valign
showLoading --> gallery_show_loading
Convert gallery.show_full_size.js to be a jQuery function and give it a namespace:
show_full_size --> gallery_show_full_size
javascript lib (gallery.reload.js) which defines the functions
gallery_reload() and gallery_location(new_location). They just
do a window.location.reload() and window.location = new_location.
This change breaks the assumption that all themes will handle page reloads
the same and allows the theme to customize the page refresh.
action. The expectation is that we're going to reload the page (or
redirect to a new url). If we close the dialog, then we can trigger
the onhover for items we've just deleted causing errors.
Simplify the API while we're at it by getting rid of the no-longer-used
on_success argument to openDialog()
This fixes#528.
allows the form in the dialog todo custom processing when the form
closes.
For example, the server_add dialog (next commit) uses this callback to
determine if the upload task was cancelled and display a warning
message when the page reloads.
Usage:
$("#gServerAdd form").bind("form_closing", function(target){...});
1) Shuffled code around to create a on_form_loaded function
2) Check for a data.reset string in the json return. If it exists and
is a function then call. The idea being that if there is an error we
might have to reset some jquery widget initialization.
