我正在尝试在“ https://dribbble.com/jobs”上刮擦公司的名称

Question

当我尝试以下代码时，它只会再次返回第一项。我是python新手，不胜感激。

import pandas as pd 
from selenium import webdriver
from time import sleep
driver = webdriver.Chrome('/Users/user/Downloads/chromedriver_win32/chromedriver')
driver.get('https://dribbble.com/jobs')
assert 'Dribbble' in driver.title 
columns = ['company']
count = 0
jobs = pd.DataFrame(columns=columns)
for item in range(10): 
            company_elem = "job-board-job-title"
            company = driver.find_element_by_class_name(company_elem).text
            item+=1
            jobs.loc[item] = [company]
driver.close()  

Answer 1

import pandas as pd
from selenium import webdriver
# from time import sleep
driver = webdriver.Chrome(r'E:\data\python\pycharm\chromedriver_win32\chromedriver.exe')
driver.get('https://dribbble.com/jobs')
assert 'Dribbble' in driver.title
columns = ['company']
count = 0
jobs = pd.DataFrame(columns=columns)
# for item in range(10):
# company_elem = "job-board-job-title"
companies = driver.find_elements_by_class_name("job-board-job-title")
for i in companies:
     print(i.text)
# count += 1
# jobs.loc[count] = [company]
# print(jobs)
driver.close()

现在对代码进行了一些更改，您需要获取所有元素，而不是使用find元素的地方，而是使用find元素。 https://selenium-python.readthedocs.io/locating-elements.html#locating-elements-by-class-name

Answer 2

您只能更改一行，因此不能更改

company = driver.find_element_by_class_name(company_elem).text

尝试

company = driver.find_elements_by_class_name(company_elem)[item].text

输出将是：
