AJAX Python Call Definition

Question

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?
});

Answer 1

$.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);
        }
    }
});
