What is the best practice for making an AJAX call in Angular.js?

I just want to send requests and get responses using AngularJs, but I haven't tried anything yet.
The $http-service is what you are looking for. It comes with preconfigured get and post methods to make easy requests, but you can also configure your requests as you wish.
You can use $http service or restangular for that. https://github.com/mgonto/restangular

I really don't understand how Php works and i am a little nervous, i don't like the idea of using more application for a email-send system. Is there anyway to do that without php, only in javascript/html/css? Can someone explain how this works or if is there something i need to know?
I tried to find on google, but i didn't find anything useful. Thanks in advance! :)
Sending mail requires a program to run on a server, and PHP is a language that can talk to a server. You can't send an email using just HTML, CSS and Javascript.

I am in the starting stages of a web project which uses Java to connect to a server and retrieve the data from the server. I have created the initial html page which accepts some values from the user like employee id etc. which has to stored in a Java object and sent to the server.
How do I store the data into a Java Object from my html page? I have searched through a lot of sites but did not find anything satisfactory.
Any guidance would be welcome.
Thanks in advance.
You need to write Java REST API, and make a post call from your form, along with your formdata.
You need something handling HTTP requests. In Java you have few options and I recomend to read about Servlets(easiest, lightweight solution) or for example REST Webservices, SpringMVC but those are more complex solutions.
You will alse need at least servlet container like Tomcat to deploy your web application with servlets.
I would recommend to use a Web API framework, like Dropwizard.
http://www.dropwizard.io/1.0.5/docs/getting-started.html
There are alternatives, but reading this page should give you an impression of how a REST API works. To explain the basis; you create a java API that handles all HTTP calls from your front end application, which contains html/css/js. you post data to your Java API. The framework helps you to receive this calls, which you can then process using your backend (Java) logic.
you need to read about the following topics:
1: making post request to your server with the formdata.
2: reading the request parameters from HttpServletRequest, since it would contain your formdata.
3: Finally you need to assign the values read from the request, to your object.

HTTP GET request in JavaScript?

I want to send an async HTTP request from the HTML, parse a response, and update an HTML page respectively. Is there a way to do it without using AJAX or any other third-party library?
I'd like to find the most basic way to do this.
Since libraries can do it, it should be possible without them too.
Worth saying, that I'm a mobile developer who checks web development for a couple of days.
UPDATE 1
I didn't have to call AJAX a "third-party library". My bad.
UPDATE 2
Thanks everybody who responded. What I've learned: the only way to do what I wanted is AJAX, in particular, XMLHttpRequest.
There is no way without JS. The most basic way is to either use the new fetch() API, or good old XMLHttpRequest() link

Actually I add these js files to start my Angular 2 app:-
But my page is loading around 400 Http calls, which is making app a bit slower.
out of these 400 calls 200 calls are initiating from system.js, please see in this pic
Is there a way to make it faster ??
Make sure you are using the minimized version of the file and use a CDN for delivery.

Abort Ajax requests using jQuery

Can I cause an xhr request to interrupt/terminate clientside? I have a number of long running requests, and I want to abandon them once they're no longer relevant.
I believe xhr.abort() is what you're looking for.
