EDITED

我正在尝试使用jquery/ajax来显示从django方法返回的数据.

我有一个名为keywordBtn的html按钮.因此,当按下它时,将调用updateKeywordSubscribed方法.

但是,我的目标不是由django返回的.我的方法有问题吗？

如果成功,div部分名称"update"将显示该json列表中的单词列表.

我的HTML中有什么:

<script type="text/javascript">
        $(document).ready(function() { 
            $("#keywordBtn").click(function(e) { 
                updateKeywordSubscribed(e, "#keywords"); 
            });
        });
        function updateKeywordSubscribed(e, keywords) {
            e.preventDefault();
            var option_form = jQuery(e.target);
            $.ajax({
                url : option_form.attr('action'),
                type : option_form.attr('method'),
                data : option_form.serialize(),
                dataType : 'json',
                success : function(response) { alert ('sometext')})
        }
</script>

我在views.py中的内容:

def keyword_subscribe(request):
    if 'keyword_input' in request.POST:
    if 'name_input' in request.POST:
        xhr = request.GET.has_key('xhr')
        response_dict = {}
            new_keyword = request.POST['keyword_input']
        username = request.POST['name_input']
        response_dict.update({'keyword_input': new_keyword, 'name_input': username})
        power_keyword = subscribe_keyword(username,keywords)
        if power_keyword:
            response_dict.update({'success':True})
        else: …

您好我正在尝试检查复选框是否已选中.但是我的复选框是使用for循环创建的,每个复选框的值实际上是相同的.

代码如下:

{% for keyword in keyword_list %}
    {% if keyword.keyword_name == userprofile.keywords_subscribed  %}
        <input type="checkbox" disabled="disabled" name="keywords" value="keywords"/>   {{keyword.keyword_name}}<br />
    {% else %}
        <input type="checkbox" name="cb" value="keywords"  />   {{keyword.keyword_name}}<br />
    {% endif %}
{% endfor %}

Jquery代码如下:

<h2>Price of subscriptions</h2>
    <script type="text/javascript" src="/static/js/jquery-1.6.3.min.js"></script>
    <script type="text/javascript" src="/static/js/jquery-ui-1.8.16.custom.min.js"></script>
    <script type="text/javascript" src="/static/fc3/charts/FusionCharts.js"></script>
    <script type="text/javascript">
    function popup(){
        {% for price in price_list %}
            alert({{price.price_of_each_keyword}})
        {% endfor %}
    }
    function DoTheCheck() { if(document.cb2.checked == true)
                { alert('box2 is checked'); }
    }

    </script>

目前这是我能想到的全部.

那么我如何使用jquery遍历复选框并检查它们是否被选中？ …

我最近尝试使用以下内容扩展django的注册表单,但我只能看到默认的四个字段.有什么我想念的吗？

或者,如果我要创建自定义表单,我应该创建自己的注册后端吗？

class RegistrationForm(forms.Form):

    username = forms.RegexField(regex=r'^\w+$',
                                max_length=30,
                                widget=forms.TextInput(attrs=attrs_dict),
                                label=_(u'Username'))
    email = forms.EmailField(widget=forms.TextInput(attrs=dict(attrs_dict,
                                                               maxlength=75)),
                             label=_(u'Email address'))
    first_name =forms.CharField(widget=forms.TextInput(attrs=attrs_dict),label=_(u'First Name')) 
    last_name =forms.CharField(widget=forms.TextInput(attrs=attrs_dict),label=_(u'Last Name'))
    password1 = forms.CharField(widget=forms.PasswordInput(attrs=attrs_dict, render_value=False),
                                label=_(u'Password'))
    password2 = forms.CharField(widget=forms.PasswordInput(attrs=attrs_dict, render_value=False),
                                label=_(u'Password (again)'))
    keywords = forms.ModelMultipleChoiceField(queryset=Keyword.objects.all())
    #keywords = forms.ModelChoiceField(queryset=Keyword.objects.all())

    def clean_username(self):
        try:
            user = User.objects.get(username__iexact=self.cleaned_data['username'])
        except User.DoesNotExist:
            return self.cleaned_data['username']
        raise forms.ValidationError(_(u'This username is already taken. Please choose another.'))

    def clean(self):
        if 'password1' in self.cleaned_data and 'password2' in self.cleaned_data:
            if self.cleaned_data['password1'] != self.cleaned_data['password2']:
                raise forms.ValidationError(_(u'You must type the same password each …

我正在尝试将用户userID合并到侧边栏上.

所以侧边栏会显示"欢迎用户名"

我尝试过cookie方法,但似乎没有用.

这是我的cookie收到我的用户名:

def login_user(request):
    state = "Please log in below..."
    username = password = ''
    if request.POST:
        username = request.POST.get('username')
        password = request.POST.get('password')

        user = authenticate(username=username, password=password)
        if user is not None:
            if user.is_active:
                login(request, user)
                state = "You're successfully logged in!"
                cookie = Cookie.SimpleCookie()
                cookie['username']=str(time.time())
                return render_to_response('r2/topic/index.html',{})
            else:
                state = "Your account is not active, please contact the site admin."
        else:
            state = "Your username and/or password were incorrect."
            return render_to_response('registration/login.html',{'state':state, 'username': username})

    return render_to_response('registration/login.html',{'state':state, 'username': username}) …
