I did it the following way:
An action returns the rendered view if there were errors while saving
the data, otherwise it returns xml that contains info including what
page element should be refreshed etc.
JS code:
# make form "ajax"
var makeAjaxForm = function(){
$('form',this).ajaxForm({
//onActionSubmit will be fired when the response
is received
success: onActionSubmit
});
};
#reloads form on error or sends response xml to processing
var onActionSubmit = function(responseText) {
//if the response is xml
if(jQuery.isXMLDoc(responseText)) {
//process it, reload some elements etc
processXML(responseText);
//hide form
hideActionBox();
} else {
//load the rendered view into #reqAction .content (the
form container)
$('#reqAction .content').html(responseText);
//make the form ajax again
makeAjaxForm();
}
};
