python +selenium识别不来click事件，出现报错

assert "login" in browser.title

browser.implicitly_wait(10)

elem = browser.find_element_by_id("txtAccount") # Find the query box elem.send_keys("0@cm.com")

log=browser.find_element_by_id("txtPwd2") log.send_keys("123456" + Keys.RETURN)

#be carefully the big-small time.sleep(2)# Let the page load, will be added to the API #

browser.find_elements_by_xpath("//ul[@id='menu']/li[2]/a").click() print"contract to be assigned"

browser.implicitly_wait(10) browser.find_elements_by_xpath("//body/div[2]/div/div/div[2]/table/tbody/tr/td/a").click()

报错信息：

Traceback (most recent call last): File "E:\eclipse\PythonCase\src\Python27\btn_test.py", line 20, in <module> browser.find_elements_by_xpath("//body/div[2]/div/div/div[2]/table/tbody/tr/td/a").click() AttributeError: 'list' object has no attribute 'click'

解决办法：

browser.find_elements_by_xpath("//body/div[2]/div/div/div[2]/table/tbody/tr/td/a") 这个方法返回一个list webelement 的集合

要想返回单个webelement 得用browser.find_element_by_xpath，这个要特别注意对于初学者加S和不加S的区别
