Im starting to study ajax, and I did my first example reading a tutorial.

In my first example, Im deleting images from a gallery, without loadingmy page.

I have a jQuery function that executes when I click in my image with class "imagesdel", and then I get id of my image to use in my post.

$(function(){

var url = 'delImage.php';

$('.images ul').on('click','.imagesdel',function(){

 var delId = $(this).attr('id');

 $('.images ul li[id="'+ delId +'"]').css('background','green');

 $.post(url,{action:'del_images',image:delId},function(){

  window.setTimeout(function(){

$('.images ul li[id="'+ delId +'"]').fadeOut("slow");

},500);

 });

 return false;

});

And then in my del_images.php I get my action: $action = $_POST['action']; And I do my delete where id is like my  $_POST['image'];

And this is works, When I click in my image I delete without load my page. 

But Im not using ajax like $.ajax({}); So Im asking if $.post(URL,data,callback);  can do the same of using $.ajax({})??

And if it is the same, when should we use one instead of other?
