Question

我的视图中有以下代码，它将数据发送到模板，如下所示 -

<script>
    function postContactToGoogle() {
        var email = $('#Email').val();
        var fullname = $('#FullName').val();
        var subject = $('#Subject').val();
        var details = $('#Details').val();
        $.ajax({
            url: "https://docs.google.com/forms/d/abcdefgh1234567xyz/formResponse",
            data: {
                "entry.805356472": fullname,
                "entry.1998295708": email, 
                "entry.785075795":  subject, 
                "entry.934055676": details
            },
            type: "POST",
            dataType: "xml",
            statusCode: {
                0: function () {
                    window.location.replace("Success.html");
                },
                200: function () {
                    window.location.replace("Success.html");
                }
            }
        });
    }
</script>

在我的模板中，我可以访问上下文项目 -

@page_template("app/Discover.html") 
def Discover(request, template="app/Discover.html", extra_context=None):    
    context = {}
    context['to_loc']=loc_both
    context['to_av']=av_both
    context['to_ql']=ql_both    
    if extra_context is not None:
        context.update(extra_context)
    return render_to_response(template, context, context_instance=RequestContext(request))

这种方式可以从上下文访问单个项目。但是，我有什么方法可以做如下的事情 -

将上下文对象分配给javascript数组对象，此javascript数组包含上下文对象列表 - ＆gt;我可以访问如下 -

{% if to_loc %}
js_loc = {{ to_loc|safe }};       
{% endif %}
alert('Location is : '+JSON.stringify(js_loc,null,2));

{% if to_av %}
js_av = {{ to_av|safe }};       
{% endif %}
alert('AV is : '+JSON.stringify(js_av,null,2));

如何将整个上下文对象分配到js文件中的javascript对象contextJSON中作为数组？

您可以将您的上下文作为JSON对象放入其中：

@page_template("app/Discover.html") 
def Discover(request, template="app/Discover.html", extra_context=None):    
     context = {}
     context['to_loc']=loc_both
     context['to_av']=av_both
     context['to_ql']=ql_both    
     if extra_context is not None:
         context.update(extra_context)
     ctx_copy = context.copy()
     context['context_json'] = simplejson.dumps(ctx_copy)
     return render_to_response(template, context, context_instance=RequestContext(request))

只需将其作为JavaScript变量呈现在模板中：

jsonList = [];
jsonList = {{ context_json|safe }};  // contextJSON holds the context objects that are sent by my view above
print(JSON.stringify(jsonList.to_loc));  // this should give me the data of locations from respective context object
print(JSON.stringify(jsonList.to_av)); // this is for for AV

如何访问模板中的render_to_response上下文（数据）作为数组对象？
