Django with a Side of Ajax and Javascript

The layout of my model is set up as follows:

class A(models.model):
    options = models.ManyToManyField(OptionSet, blank=True, null=True)
    values = models.ManyToManyField(Value, blank=True, null=True)

class OptionSet(models.model):
    name = models.TextField(unique=True)
    values = models.ManyToManyField(Value)

    def __unicode__(self):
        return '%s' % self.name

class Value(models.Model):
    name = models.TextField()
    key = models.ForeignKey(Key, related_name='values')

class Key(models.Model):
    name = models.TextField(unique=True)

In my forms.py file, the code I have written looks like this:

class A_Form(ModelForm):
    values = forms.ModelMultipleChoiceField(queryset=Value.objects.all(), widget=CheckboxSelectMultiple, label="Einzelne Werte", required=False)
    options = forms.ModelMultipleChoiceField(queryset=OptionSet.objects.all(), widget=CheckboxSelectMultiple, label="Optionen Sets", required=False)

For the template design, I have included the following code snippet:

<form action="." method="POST">{% csrf_token %}
    {{ form.as_table }}
    <input type="submit" value="Update"/> 
</form>

I am utilizing this form with a generic update view. While I have limited experience in javascript/ajax, I would like to implement a feature where upon hovering over the option's name, all the values associated with that specific option set are displayed. How can I achieve this functionality using javascript/ajax?

Utilizing jquery's .post() function, you have the ability to transmit the active option's name to a django script (specifically a URL on the server). Afterward, you can retrieve all of the values by executing queries (assuming there is prior knowledge in extracting data from models). Finally, you can proceed to use HttpResponse() for delivering the compiled list of calculated values back to your webpage.
