如何将DjangoAjax数据传递给模板？

我试图通过ajax将2d数组传递到模板中。我设法在单击时从服务器获取数据，但我不知道如何在模板中处理这些数据。例如，如果我将返回的“data”放入div，那么它只列出第一列。如何访问特定数据，例如：

{% for printers in printer_list %}
    {{ printer.email }}
{% endfor %}

Javascript:

$(".printersToggle").click(function() {
    $.get("/ajax", function(data) {
        /* What goes here? */
    });
});

views.py：

def ajax_test(request):
    if request.is_ajax():
        printer_list = User.objects.all()
    else:
        printer_list = "Not ajax"
    return HttpResponse(printer_list)
    # Am I doing this bit right?

URL.py：

url(r'^ajax$','website.views.ajax_test'),

---

这必须使用javascript来完成。一旦在服务器上生成模板，页面显示在访问者的web浏览器中，它就只不过是带有JavaScript的HTML。为了操作页面，您需要使用JavaScript。

Views.py

下面我们将收到一篇AJAX帖子，并根据“VarID”过滤一个对象，并构建一个字典列表，每个字典都包含OptionID、OptionValue和OptionLabel值。最后，您应该转换json中所需的任何列表、dict或combo

   def currentoptions(request):
        if request.is_ajax():
            currentOptions = Option.objects.filter(VariableID=int(request.POST['VarID']))
            response = []
            for i in currentOptions:
                vallabel = {}
                vallabel['OptionID'] = i.id
                vallabel['OptionValue'] = i.Value
                vallabel['OptionLabel'] = i.Label
                response.append(vallabel)
            json = simplejson.dumps(response)
            return HttpResponse(json, mimetype="text/json")
        else:
            pass

出于CSRF原因需要Javascript。

<script type="text/javascript"> 
jQuery(document).ajaxSend(function(event, xhr, settings) {
    function getCookie(name) {
        var cookieValue = null;
        if (document.cookie && document.cookie != '') {
            var cookies = document.cookie.split(';');
            for (var i = 0; i < cookies.length; i++) {
                var cookie = jQuery.trim(cookies[i]);
                // Does this cookie string begin with the name we want?
                if (cookie.substring(0, name.length + 1) == (name + '=')) {
                    cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                    break;
                }
            }
        }
        return cookieValue;
    }
    function sameOrigin(url) {
        // url could be relative or scheme relative or absolute
        var host = document.location.host; // host + port
        var protocol = document.location.protocol;
        var sr_origin = '//' + host;
        var origin = protocol + sr_origin;
        // Allow absolute or scheme relative URLs to same origin
        return (url == origin || url.slice(0, origin.length + 1) == origin + '/') ||
            (url == sr_origin || url.slice(0, sr_origin.length + 1) == sr_origin + '/') ||
            // or any other URL that isn't scheme relative or absolute i.e relative.
            !(/^(\/\/|http:|https:).*/.test(url));
    }
    function safeMethod(method) {
        return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
    }

    if (!safeMethod(settings.type) && sameOrigin(settings.url)) {
        xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
    }
});
</script>

jQuery（文档）.ajaxSend（函数（事件、xhr、设置）{
函数getCookie（名称）{
var-cookieValue=null；
if（document.cookie&&document.cookie！=''）{
var cookies=document.cookie.split（“；”）；
对于（变量i=0；i

针对特定AJAX请求的Javascript。

<script type="text/javascript"> 
jQuery(document).ajaxSend(function(event, xhr, settings) {
    function getCookie(name) {
        var cookieValue = null;
        if (document.cookie && document.cookie != '') {
            var cookies = document.cookie.split(';');
            for (var i = 0; i < cookies.length; i++) {
                var cookie = jQuery.trim(cookies[i]);
                // Does this cookie string begin with the name we want?
                if (cookie.substring(0, name.length + 1) == (name + '=')) {
                    cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                    break;
                }
            }
        }
        return cookieValue;
    }
    function sameOrigin(url) {
        // url could be relative or scheme relative or absolute
        var host = document.location.host; // host + port
        var protocol = document.location.protocol;
        var sr_origin = '//' + host;
        var origin = protocol + sr_origin;
        // Allow absolute or scheme relative URLs to same origin
        return (url == origin || url.slice(0, origin.length + 1) == origin + '/') ||
            (url == sr_origin || url.slice(0, sr_origin.length + 1) == sr_origin + '/') ||
            // or any other URL that isn't scheme relative or absolute i.e relative.
            !(/^(\/\/|http:|https:).*/.test(url));
    }
    function safeMethod(method) {
        return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
    }

    if (!safeMethod(settings.type) && sameOrigin(settings.url)) {
        xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
    }
});
</script>

为了在列表中显示DICT中的值，我们在AJAX请求成功时遍历返回的数据。JS函数是用jQuery完成的

function AddOptions(VarID){
           $.ajax({
                type:"POST",
                url:"{% url builder.views.currentoptions %}",
                data: {VarID: VarID},
                success: function(data){
                $('#OptionTable > tbody > tr').remove();
                  $.each(data, function(index) {
                  $('#OptionTable > tbody:last').append('<tr id=Option_'+data[index].OptionID+'><td>'+data[index].OptionValue+'</td><td>'+data[index].OptionLabel+'</td><td><a href="#" onClick="deleteOption('+data[index].OptionID+')"><i class="icon icon-remove"></i></a>');
                  });
                }
              });
           }

函数添加选项（变量）{
$.ajax({
类型：“POST”，
url:“{%url生成器.views.currentoptions%}”，
数据：{VarID:VarID}，
成功：功能（数据）{
$（'#OptionTable>tbody>tr'）。删除（）；
$。每个（数据、函数（索引）{
$（'#OptionTable>tbody:last'）.append（''+data[index].OptionValue+''+data[index].OptionLabel+''）；
});
}
});
}

谢谢，我想我缺少的是javascript（参见我的代码）！您需要包含模板代码，以便我们可以看到HTML是如何生成的。我想使用我在原始问题中输入的模板代码。与其在AJAX调用中返回queryset，不如将其作为JSON对象返回。然后，您必须循环遍历JSON对象，并使用javascript插入其中的数据。此外，模板代码不显示生成的HTML。它是在div中还是在列表中？
