Question

使用Django 1.5和JQuery，我无法从我的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() });
}

我的观点代码是：

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：来自网页导入视图

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"),

错误的开头是：

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

CSRF因调试目的而被禁用，我稍后会将其打开
使用Firebug，我看到来自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的事情，可能是网址重定向，但我找不到我的设置有什么问题。

这是你的问题：你在开始时调用console.log，这样你就可以看到$("#email").val()存在，但是你通过调用email来删除$('#getemailbutton').html(ending)输入。最后，当调用$.post()时，$("#email")不再存在。将该值保存到某个变量中，以后可以使用：

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 });
}

Django 1.5丢失了表单中的数据
