how to use ajax in jQuery in javascript

Question

I want to post javascript variable to another php file and I search using Ajax may help.I want to get back the data on another php file by "post" method.But I can't use $.ajax({}) directly inside javascript:

function input() {
    $.ajax({
        url : 'update_service.php',
        type : 'POST',
        data : {
            name: name,

        },
        success : function(response) {
            alert(response);
        }
    });

The error message said "unexpected function ajax()". How to fix it?
