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',
function (data, textStatus, jqXHR) {
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');
}
});
});
