By using the deferred object in $.ajax
deferred-method done()
deferred-method fail()
always()
by using
var jqxhr = $.ajax({
url: Config.baseUrl+"/ajax/favourites/set-favourite.ajax",
dataType: "json",
data: attrs,
type: "POST",
beforeSend: function(){
console.log("before send");
}
});
how can i implement the beforeSend-callback
by using the deferred object?
why i don't use the beforeSend-callback inside the $.ajax
function? Because the request is inside a Model-Instance ( http://canjs.com/docs/can.Model.model.html#section_Non_standardServices ) so the model object do the request and all the other suff, like manipulate the DOM will done in the deferred object. i would like to manipulate the DOM before sending the ajax request.
how could i do that?
You could attach the global jQuery event ajaxStart
to whatever element is triggering your AJAX request. That should essentially replicate the functionality of beforeSend
.
$(".ajax").ajaxStart(function() {
$(".document").append("AJAX begun");
});
Fiddle .
