使用 Django 1.5 和 JQuery，我无法从视图中的表单中检索数据。

我的 HTML 代码是：

<form method="post" class="form-inline" id="getemailbutton" onsubmit="getemail();return     false">
<input type="text" id="email" class="input-small" placeholder="Email" />
<button name="submit" type="submit" class="btn" >Go!</button></form><!-- end of email form -->

我的 JS 代码是：

function getemail(){
    div = 'getemailbutton';
    ending="Thanks! We will contact you asap.";
    console.log($('#email').val());
    $('span#getemailbutton').css('display','none');
    $('#getemailbutton').html(ending).fadeIn();
    $.post("/getemail/",{ "email" : $('#email').val() });
}

我的视图代码是：

def getemail(request):
    email = request.POST['email']
    message = ("New lead by email:%s\n" % email)
    Mail(message)
    return HttpResponse(status=204)

我的 urls.py 如下： from web import views

urlpatterns = patterns('',
    url(r'^$', TemplateView.as_view(template_name="index.html")),
    url(r'^index/', TemplateView.as_view(template_name="index.html")),
    url(r'^features/', TemplateView.as_view(template_name="features.html")),
    url(r'^offer/', TemplateView.as_view(template_name="offer.html")),
    url(r'^whatfor/', TemplateView.as_view(template_name="whatfor.html")),
    url(r'^contact/', TemplateView.as_view(template_name="contact.html")),
    url(r'^getemail/', views.getemail, name="getemail"),
    url(r'^getphone/', views.getphone, name="getphone"),

错误的开始是：

"Key 'email' not found in <QueryDict: {}>"

Context:
  • 出于调试目的禁​​用 CSRF，稍后我将打开它
  • 使用 Firebug，我看到从 HTML 到 JS 脚本的数据有效，因为好的值出现在 JS 的 console.log() 中。
  • 我怀疑有关 Django 的一些问题，可能是 url 重定向，但我找不到我的设置有什么问题。

这是您的问题：您console.log在开始时调用，因此您可以真正看到它的存在，但是然后您通过调用 that 来$("#email").val()删除输入。所以最后，何时被调用，不再存在。将该值保存到某个变量中，以后可以使用：email$('#getemailbutton').html(ending)$.post()$("#email")

function getemail(){
    div = 'getemailbutton';
    ending="Thanks! We will contact you asap.";
    console.log($('#email').val());
    var email = $('#email').val()'
    $('span#getemailbutton').css('display','none');
    $('#getemailbutton').html(ending).fadeIn();
    $.post("/getemail/",{ "email" : email });
}
