jQuery POST不返回变量用户 [英] jQuery POST not returning variable users

问题描述

我正在尝试发布复选框的值，但无法这样做。它首先收集一个数组中的所有复选框（ selected_users ，它在使用 alert 函数测试时工作正常。然后集体发送。但是我无法发布数据。我得到的错误是没有找到密钥的用户。我哪里错了？如何在jQuery插件中修改POST语句？

I am trying to post the values of checked boxes, but unable to do so. It first collects all the checked boxes in an array (selected_users-which is working fine upon testing it with alert function )and then sends them collectively. But I'm not able to post the data. The error that I get is Key 'users' not found in . Where i'm going wrong? how do I modify my POST statement in jQuery plugin?

View.py

def get_data（request）：

def get_data(request):

if request.method == 'POST': 
    selected_users = request.POST['users']
return HttpResponse(selected_users)

urls.py

urlpatterns = patterns('',
    url(r'get_data/','apps.api.views.get_data', name = 'grabhalo_get_data'),
)

jQuery

$(document).ready(function(){
                $('#submit').click(function() {
                  var selected_users = $('input[type=checkbox]:checked').map(function(_, el) {
                    return $(el).val();
                    }).get();
                    alert(selected_users);     // works fine
                    $.post("get_data/",{users:selected_users});   // not able to post
                });    
            })

复选框

{% for user in users %}
    <input type="checkbox" class="check" value="{{user.id}}" />{{user.name}}<br>    
{%endfor%}

    <form id="form" method="POST" action="/get_data/">
       {% csrf_token %}
       <input type="text" class="span8 search-query" placeholder="Type here..." name="chat">
       <input type="submit" value="Send" class = "btn btn-primary" id = "submit">
   </form>

不同的建议是受欢迎的，如果有人可以重新定义.post功能。

Different Suggestions are welcomed , if anyone can redefine the .post function.

谢谢

你只需要结合@Aditya和@Yurly的答案：

You just have to combined @Aditya and @Yurly answers:

脚本

function get_csrf_token(){
    return $("input[name='csrfmiddlewaretoken']").val();
}

$(document).ready(function(){
    $('#submit').click(function() {
        var datas = new Array();
        var i = 0;
        var csrf_token = get_csrf_token();

        $("input[type=checkbox]:checked").each(function() {
            datas[i] = $(this).val();
            i++;
        });   

        #make sure the url is correct
        $.post("get_data/", {'users[]': datas, 'csrfmiddlewaretoken': csrf_token}, function(data){
            alert(data);
        });   
    });    
})

views.py

if request.method == 'POST':
    selected_users = request.POST.getlist('users[]')
    return HttpResponse(selected_users)
