Example 3: jquery get request

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.

Example 4: jquery ajax responseText

// To get jquery AJAX calls working
// remember to add Jquery to your head tag:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>

var response = null;
var responseTextValue = null;

$.ajax({
	type: "GET",   
	url: "<Your url text>",   
	async: false,
	success : function(data) {
		// Here you can specify that you need some exact value like responseText
		responseTextValue = data.responseText;
	    response = data;
	}
});
