我在网页上有一个HTML表格，其中有很多行和几列。 我正在迭代表以检查第2列和第3列是否有一些数据。它不是空的。 Col2的值为1，col 3的值为Mrs | Sue | a | Female
我收到以下错误：
Traceback (most recent call last):
File "C:\Webdriver\ClearCore 501 Regression Test\ClearCore - Regression Test\TestCases\ReportingPage_TestCase_Regression.py", line 73, in test_a2_view_all_records_report
self.assertTrue(reports_view_results_page.is_view_report_showing_results2(), "Problem with viewing report. Please see log for details")
File "C:\Webdriver\ClearCore Regression Test\ClearCore - Regression Test\Pages\Reports\reports_view_results.py", line 108, in is_view_report_showing_results2
col_usn = row.find_elements(By.TAG_NAME, "td")[2] # This is the USN column
IndexError: list index out of range
迭代表的我的Selenium Python方法是：
def is_view_report_showing_results2(self):
try:
#WebDriverWait(self.driver, 20).until(
# EC.presence_of_element_located((By.ID, 'reporting_view_report_dg_main_body')))
table_id = WebDriverWait(self.driver, 20).until(
EC.presence_of_element_located((By.ID, 'reporting_view_report_dg_main_body')))
rows = table_id.find_elements(By.TAG_NAME, "tr")
for row in rows:
# Get the columns
col_usn = row.find_elements(By.TAG_NAME, "td")[2] # This is the USN column
col_2 = row.find_elements(By.TAG_NAME, "td")[3] # This is the 2nd, column Source Fields
print "col_usn.text = "
print col_usn.text
print col_2.text
if (col_usn.text is not None) and (col_2.text is not None):
return True
return False
except NoSuchElementException, e:
print "Element not found "
print e
self.save_screenshot("is_view_report_showing_results2")
return False
