Flask WTForms Integerfield类型是文本而不是数字 [英] Flask WTForms Integerfield type is text instead of number

问题描述

这是我尝试过的:

nrkomp = IntegerField('Number',validators=[NumberRange(min=1, max=5, message='Invalid length')])

在开发人员工具中，此表单输入具有文本类型而不是数字，我已经阅读了文档，但是找不到解决此问题的方法.

In developer tools, this form input has type text and not number, I have read the docs, but could not find a solution to this problem.

推荐答案

您可以使用wtforms html5

You can use wtforms html5 fields to get html5 input types, and html5 widgets as their associated widgets.

from wtforms import Form
from wtforms.fields import html5 as h5fields
from wtforms.widgets import html5 as h5widgets


class F(Form):

    n1 = h5fields.IntegerField("Number1")
    n2 = h5fields.IntegerField(
        "Number2", widget=h5widgets.NumberInput(min=0, max=100, step=10)
    )


for f in F():
    print(f)

<input id="n1" name="n1" step="1" type="number" value="">
<input id="n2" max="100" min="0" name="n2" step="10" type="number" value="">
