问如何在Django视图中访问jQuery.ajax() get参数

EN

<div id="browser">
    <ul>

    {% comment %}
        Theres a script for each ctg. Each script fades out #astream, fades in #stream_loading and then it should display #astream with new values based on the GET param in ajax call
        Prolly it wont work, but first I need to interact with the GET param in my views.py
    {% endcomment %}

    {% for ctg in ctgs %}
        <script type="text/javascript" charset="utf-8">
            (function($) {
                $(document).ready(function() {
                    $("#stream_loading").hide()

                    $("#browse_{{ctg}}").click(function() {

                        $("#astream").fadeOut()
                        $("#stream_loading").fadeIn()

                        $.ajax({
                            type: "GET",
                            url: "/{{defo}}/?param={{ctg}}",
                            success: function() {
                                $("#stream_loading").fadeOut()

                                $("#astream").fadeIn()
                            }
                        });
                    });
                });
            })(jQuery);
        </script>
