selenium执行js

写一个字符串来定义js代码

使用execute_script（）执行js代码

        province_js = '''
            b= document.querySelector('ul[class="ant-cascader-menu"]:nth-child(1) >li:nth-child(1)');
            b.click()
            '''
        self._driver.execute_script(province_js)
        city_js ='''
            b= document.querySelector('ul[class="ant-cascader-menu"]:nth-child(2) >li:nth-child(1)');
            b.click()
        '''
        sleep(0.5)
        self._driver.execute_script(city_js)
        area_js = '''
            b= document.querySelector('ul[class="ant-cascader-menu"]:nth-child(3) >li:nth-child(1)');
            b.click()
        '''
        sleep(0.5)
        self._driver.execute_script(area_js)

列子：

    def select_provinces(self,provinceJs,cityJs,areaJs):
        '''
        省市区选择框
        :param provinceJs:
        :param cityJs:
        :param areaJs:
        :return:
        '''
        self.execute_js(provinceJs)
        sleep(0.3)
        self.execute_js(cityJs)
        sleep(0.3)
        self.execute_js(areaJs)
