How to send POST request in JavaScript?

How to send POST request in JavaScript from the users’ browsers?

One easy method I find is to use the jQuery library’s post() method.

Here is one example that send POST request with data “file: filename” to the “/fileview” URL on the server and show the replied data:

$.post("/fileview", {file: filename}, function (data) {
     // actions upon receiving the reply
     alert("Data received: " + data);
});
