Question

在我的标识页上使用Django的表格。 <代码>I 想把重点放在第一稿上页: 1 我尝试使用Jquery如下,但确实没有结果。

forms.py:
from django import forms
class LoginForm(forms.Form):
    userName = forms.EmailField(max_length=25)     
    password = forms.CharField( widget=forms.PasswordInput, label="password" )

login.html

% block headextra %}
    <script type="text/javascript">
        $(document).ready(function() {
             window.onload = function() {
             $("#id_username").focus();
             // alert( test ) if I add this line its works
             //  setting focus to a textbox which added to template page direcltly using html tag the focus() method works well
            };  
        }); 
        </script>       
    {% endblock %}

{% block content %} 
<form method = "POST" action ="/login/">{% csrf_token %}
<table align ="center">
    {{ form.as_table }}
<tr><td></td></tr>
<tr><td><input type="submit" value="Submit"></td></tr>
</table>
</from>

Answer 1

<代码>$(“#id_username”>>

Answer 2

The proper Django way of answering this question is as follows (as it doesn t depend on js being enabled):

from django import forms

class LoginForm(forms.Form):
    user_name = forms.EmailField(max_length=25)     
    password = forms.CharField( widget=forms.PasswordInput, label="password" )

    def __init__(self):
        self.fields[ user_name ].widget.attrs.update({ autofocus :  autofocus 
             required :  required ,  placeholder :  User Name })
        self.fields[ password ].widget.attrs.update({
             required :  required ,  placeholder :  Password })

Also, for the record, we avoid the use of camelcase for object attributes. Cheers!

Answer 3

    password = forms.CharField(
        widget=forms.PasswordInput(attrs={ autofocus :  autofocus }))

for text input:

    field = forms.CharField(
        widget=forms.TextInput(attrs={ autofocus :  autofocus }))

Answer 4

在html中,你们都需要的是autofocus,没有论据。

在Django表格中,增加汽车作为具有空闲价值的钥匙:

search = forms.CharField(
                label= Search for: ,
                max_length=50,
                required=False,
                widget=forms.TextInput(attrs={ autofocus :   }))

Answer 5

我只想使用拖欠的Django标志,但添加了汽车保单,因此,我从违约中得出了新的表格。

#myapp/forms.py
from django.contrib.auth.forms import AuthenticationForm

class LoginForm(AuthenticationForm):
    def __init__(self, *args, **kwargs):
        super(LoginForm, self).__init__(*args, **kwargs)
        self.fields[ username ].widget.attrs.update({ autofocus :   })

然后,我在<代码>urls.py上指明了新形式类别:

from myapp.forms import LoginForm

urlpatterns = patterns(
      ,
    url(r ^login/$ ,  django.contrib.auth.views.login ,
        {"template_name": "myapp/login.html",
         "authentication_form": LoginForm,
         "current_app": "myapp"}, name= login ),
    #...
    )
