But with that JS you show no response type.
Success? Did it do what it was intended? No message, no alert nothing. If you sent a form did it save? Any error messages for the user?
This is a much better way::
function sendData(sel){
var $form = $(sel);
$(sel).submit(function(e) {
e.preventDefault();
$.ajax({
type: "POST",
url: $(sel).attr('action'),
data: $(sel).formSerialize(),
dataType: 'json',
error: function(response,error) {
if (error == "timeout") {
$('div#backdata').unblock();
serverTimeout ();}
},
success: function(r){
$('#backdata').html(r.html);
if (r.status === true) {
successMessage(r.message); } else {
failureMessage(r.message); }
}
});
return false;
});
};
And I have cake create the array of info $response = array('message' => Good stuff it saved, 'html' => grab my view / element whatever…., 'status' => true, anything else you want to add.)
And just server it up as a json response and presto!

Subject: Re: Cakephp Ajax helper or Jquery?
Hi Sam,
Progressive enhancement is a very elegant solution for Ajax and UI.
Build your app without any Ajax/JavaScript. Use the app controllers before filter to change the layout on ajax requests.
public function beforeFilter() {
if ($this->request->is('ajax')) {
$this->disableCache();
$this->layout = 'ajax';
}
}
Ajax requests end up looking something like this.
$.ajax({
data: $form.serialize(),
method: 'POST',
dataType: 'html',
url: $form.attr('action'),
success: function (html) {
var $html = $('<html />').html(html);
// do whatever you want with the returned chunk of html
// example: grab the flash message and fade it in
// make a chicken titty dance
}
});
Used to-do ajax similar to the Rails convention by sending JavaScript to the browser from a separate view template. Most people find progressive enhancement so much easier to maintain and it makes front end people happy.
Another tip is to attach your JavaScript handlers to html5 data attributes instead of css selectors. It's another separation and makes things even easier to maintain.

I would like to try out Ajax. May I know what are the pros and cons of Cakephp Ajax helper and Jquery? I have never touched ajax and would like to know which is a better choice as a start. Thank you very much.
