【问题描述】：

我有表 hr 和 1 个包含 hr 列表的组合框，我想向 hremail_lineEdit 和 hrphone_lineEdit 显示电子邮件和电话，但我只能向 hrphone_lineEdit 显示电话。

def hr_name(self):
    self._conn = pymysql.connect(host=127.0.0.1, port=3306, user='root', passwd=root, db='testhr', charset='utf8')
    self._cur = self._conn.cursor()
    sql_coop4hr = 'select human_name,email,phone from hr'
    count_coop4hr = self._cur.execute(sql_coop4hr)
    res_coop4hr = self._cur.fetchall()
    for row in res_coop4hr:
        un, email, phone = row
        self.hr_name_comboBox.addItem(un, email)

def hr_email(self):
    self.hremail_lineEdit.setText(self.hr_name_comboBox.currentData()) #email
    self.hrphone_lineEdit.setText(self.hr_name_comboBox.currentData()) #phone

【解决方案1】：

有几种选择：

将电子邮件和电话作为元组（或列表）传递给 userData：

self.hr_name_comboBox.clear()
for row in res_coop4hr:
    un, email, phone = row
    self.hr_name_comboBox.addItem(un, (email, phone))

def hr_email(self):
    email, phone = self.hr_name_comboBox.currentData()
    self.hremail_lineEdit.setText(email)
    self.hrphone_lineEdit.setText(phone)

为每个数据创建 2 个角色：

EMAIL_ROLE = Qt.UserRole
PHONE_ROLE = Qt.UserRole + 1

self.hr_name_comboBox.clear()
for i, row in enumerate(res_coop4hr):
    un, email, phone = row
    self.hr_name_comboBox.insertItem(i, un)
    self.hr_name_comboBox.setItemData(i, email, EMAIL_ROLE)
    self.hr_name_comboBox.setItemData(i, phone, PHONE_ROLE)

def hr_email(self):
    index = self.hr_name_comboBox.currentIndex()
    email = self.hr_name_comboBox.itemData(index, EMAIL_ROLE)
    phone = self.hr_name_comboBox.itemData(index, PHONE_ROLE)
    self.hremail_lineEdit.setText(email)
    self.hrphone_lineEdit.setText(phone)
