I want to call a definition that is located in Python with a parameter, using AJAX. The web framework I'm using is Flask.

In my test.py file:

def example(param):

In my JS file

$.ajax({
 type: 'POST',
 url: "test.py"
 //pass param here?
});
</div>

    $.ajax({
     type: 'POST',
     url: "test.py"
     data: {
        param: param
    }
    });
    

    make sure to include your CSRF token. You can learn more about it here http://flask.pocoo.org/snippets/3/

    you can add this to your js code.

    function getCookie(name) {
        var cookieValue = null;
        if (document.cookie && document.cookie != '') {
            var cookies = document.cookie.split(';');
            for (var i = 0; i < cookies.length; i++) {
                var cookie = jQuery.trim(cookies[i]);
                // Does this cookie string begin with the name we want?
                if (cookie.substring(0, name.length + 1) == (name + '=')) {
                    cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                    break;
                }
            }
        }
        return cookieValue;
    }
    var csrftoken = getCookie('csrftoken');
    
    function csrfSafeMethod(method) {
        // these HTTP methods do not require CSRF protection
        return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
    }
    $.ajaxSetup({
        beforeSend: function(xhr, settings) {
            if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
                xhr.setRequestHeader("X-CSRFToken", csrftoken);
            }
        }
    });
