Call a jQuery.ajax action function from inside a class

Question

function submit_onClick() {
    var addValue = jQuery("#billing_address_1").val();
    jQuery.ajax({
        type: "POST",
        url: "http://localhost/wordpress/wp-admin/admin-ajax.php",
        data: {'action':'distance_calculation', addValue:addValue}
    }).done(function(data) {
        alert(data);
    });
}

this works fine until I dont place distance_calculation inside any class. how can i call a function if its inside any class for example, if distance_calculation function is inside any class called "distance" then how to call this in action .

Answer 1

Have the the ajax request like so

function submit_onClick() {
    var addValue = jQuery("#billing_address_1").val();
        jQuery.ajax({
                type: "POST",
                url: "http://localhost/wordpress/wp-admin/admin-ajax.php?method=distance_calculation&addValue=addValue"
            }).done(function(data) {
                alert(data);
            });
}

Then in your PHP file add

if(strcmp($_POST["method"],"distance_calculation")){
     $class->distance_calculation($_POST["addValue"]);
}
