Flask-WTF使用input = submit而不是button type = submit

Question

我想要使​​用Flask的"SubmitField"

<button type="submit" title="Save this form"><span>Save</span></button>

代替:

<input type="submit" title="Save this form" />

我在模板中打印出来:

{{ field(class=css_class, title=field.description, **kwargs) }}

我猜我必须以某种方式修改SubmitInput(SubmitField背后的小部件),但我不确定如何做到这一点,我是否必须修改__html __()？

编辑:

from flask.ext.wtf import Required, Length, EqualTo, Field, TextInput
from flask import Markup
class InlineButtonWidget(object):
    html = """
    <button type="submit" title="%s"><span>%s</span></button>
    """

    def __init__(self, input_type='submit'):
        self.input_type = input_type

    def __call__(self, field, **kwargs):
        kwargs.setdefault('id', field.id)
        kwargs.setdefault('type', self.input_type)
        if 'value' not in kwargs:
            kwargs['value'] = field._value()
        return HTMLString(self.html % (field.name, field.label ))


class InlineButton(Field):
  widget = InlineButtonWidget()
  def _value(self):
    if self.data:
        return u', '.join(self.data)
    else:
        return u''


class SignupForm(Form):
    name = TextField('Name', [Length(min=1, max=200)])
    submit = InlineButton('sign up')

我希望能够这样做:

submit = InlineButton({'name':'submit','title':'今天注册奖品.','type':'submitfieldtype','textInsideSpan':'保存当前工作'})

它很简单,你可以像InlineButtonWidget()一样创建新的小部件,但我认为最好从表单中删除提交并在模板中使用它

<button type="submit" title="Save this form"><span>Save</span></button>

您也可以使用cource:

{% for name, label in buttons %}
    <button type="submit" title="{{name}}"><span>{{name}}</span></button>
{% endfor %}

示例小部件:

class InlineButtonWidget(object):
    html = """
    <button type="submit" title="%s"><span>%s</span></button>
    """

    def __init__(self, input_type='submit'):
        self.input_type = input_type

    def __call__(self, field, **kwargs):
        kwargs.setdefault('id', field.id)
        kwargs.setdefault('type', self.input_type)
        if 'value' not in kwargs:
            kwargs['value'] = field._value()
        return HTMLString(self.html % (field.name, field.lable ))
