jQuery get() Method
The jQuery get() method sends asynchronous http GET request to the server and retrieves the data.
Syntax:
$.get(url, [data],[callback]);
Parameters Description:
url: request url from which you want to retrieve the data
data: data to be sent to the server with the request as a query string
callback: function to be executed when request succeeds
The following example shows how to retrieve data from a text file.
Example: jQuery get() Method
$.get('/data.txt', // url
function (data, textStatus, jqXHR) { // success callback
alert('status: ' + textStatus + ', data:' + data);
});
In the above example, first parameter is a url from which we want to retrieve the data. Here, we want to retrieve data from a txt file located at mydomain.com/data.txt. Please note that you don't need to give base address.Ejemplo 3: como hacer una solicitud ajax javascript

//using JQuery
$("button").click(function(){
$.ajax({url: "demo_test.txt", success: function(result){
$("#div1").html(result);
}});
});
//To send a request to a server, we use the open() //and send() methods of the XMLHttpRequest object:

xhttp.open("GET", "ajax_info.txt", true);
xhttp.send();

<p id="demo"></p>
<script>
function loadDoc() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
document.getElementById("demo").innerHTML = this.responseText;
}
