要实现表单创建和编辑的功能,可以按照以下步骤进行:
class Form:
def __init__(self, title, fields):
self.title = title
self.fields = fields
def add_field(self, field):
self.fields.append(field)
def remove_field(self, field):
self.fields.remove(field)
class Field:
def __init__(self, name, field_type):
self.name = name
self.field_type = field_type
class FormEditor:
def __init__(self):
self.forms = []
def create_form(self, title):
form = Form(title, [])
self.forms.append(form)
return form
def edit_form(self, form, title):
form.title = title
def add_field_to_form(self, form, field):
form.add_field(field)
def remove_field_from_form(self, form, field):
form.remove_field(field)
# 创建一个表单编辑器
editor = FormEditor()
# 创建一个表单
form1 = editor.create_form("My Form")
# 创建一个字段并添加到表单中
field1 = Field("Name", "text")
editor.add_field_to_form(form1, field1)
# 编辑表单的标题
editor.edit_form(form1, "Updated Form")
# 创建另一个表单
form2 = editor.create_form("Another Form")
# 创建另一个字段并添加到表单中
field2 = Field("Email", "email")
editor.add_field_to_form(form2, field2)
# 从表单中移除字段
editor.remove_field_from_form(form2, field2)
以上代码演示了如何使用类和对象来创建和编辑表单。你可以根据具体需求进行修改和扩展。
