金字塔json查看ajax调用

I have never really worked with ajax before, so would you please be elaborate in your answers..

I have a Pyramid application where I want to load information via ajax because pre-loading it would not be feasible. So I want to load the information I need through a pyramid view, but I am unsure how to do this.
The information I need to fetch is in a MySQL database, so I guess I need to import the mouse click event object ajax_id into views.py in order to do the query. (I can get ajax_id without a problem)

In my views.py I have:

@view_config(route_name="info_ajax",renderer="json")
def info_ajax(self):

    #for the sake of this example, lets just return the information from the mouse click event
    A = ajax_id      #is the id of the mouse click event
    B = ajax_name    #is the name of the mouse click event

    return {
                'a' : A,
                'b' : B,
        }

What I would usually do is to preload all information, but that would take to long in this case, so I cannot just make a list of MySQL queries in views.py and then do <script>window.coords = ${a|query_list};</script> in my .mak file.

I want to import a and b in my JavaScript code as variables, so that I can use them again without having to reload them if need be. How do I go about doing this?

There is already an official pyramid tutorial giving enough background to solve basic AJAX tasks.

You need more tutorials?

My favorite advanced tutorial is ToDoPyramid (a Github fork)

So I figured out how to do it:

in pyramid view.py:

@view_config(route_name="info_ajax",renderer="json")
def info_ajax(self):

    #for the sake of this example, lets just return the information from the mouse click event

    A = self.request.POST.get('ajax_id')    #is the id of the mouse click event
    B = self.request.POST.get('ajax_name')   #is the name of the mouse click event

    return {
                'ID' : A,
                'Name' : B,
        }

and in JS:

    $.ajax({
        type: "POST",
        url: "details",
        dataType: "json",
        data: {
            'ajax_id': iID,
            'ajax_name': sName,
        },
        success: function(data) {
                iReturned_value = data.ID;
            }, 
    })
