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: how to get the status of other urls in ajax

$('#main-menu a').on('click', function(event) {
  event.preventDefault();

  $.ajax(this.href, {
    success: function(data) {
      $('#main').html($(data).find('#main *'));
      $('#notification-bar').text('The page has been successfully loaded');
},
    error: function() {
      $('#notification-bar').text('An error occurred');
    }
  });
});
