使用Python在Selenium中运行javascript

Question

我对Selenium完全陌生。我想在以下代码中执行一个javascript代码段（如代码中所注释），但是无法执行。请帮忙。

from selenium import webdriver
import selenium
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.keys import Keys
import time

patch = raw_input("Enter patch number\n")
rel = raw_input("Enter release\n")
plat = raw_input("Enter port\n")

browser = webdriver.Firefox()

browser.get("xxxxxxxxxxxxxxxxx")

pdtfamily = browser.find_element_by_id("prodFamilyID")
pdtfamily.send_keys("Database & Tools" + Keys.TAB)
time.sleep(5)

pdt = browser.find_element_by_id("productID")
pdt.send_keys("Intelligent Agent" + Keys.TAB)
time.sleep(5)

pdt1 = browser.find_element_by_id("patchCacheChkBxID")
pdt1.send_keys(Keys.SPACE)
time.sleep(5)

pdt7 =  browser.find_element_by_id("M__Idf")
pdt7.send_keys(plat)

pdt8 =  browser.find_element_by_id("M__Idg")
pdt8.send_keys("American English")

# Here I want to execute this javascript - "submitForm('patchCacheAdd',1,{'event':'ok'});return false"

browser.close()

如果我使用-

selenium.GetEval("submitForm('patchCacheAdd',1,{'event':'ok'});return false")

它错误地显示为-

AttributeError: 'module' object has no attribute 'GetEval'I

Answer 1

尝试browser.execute_script代替selenium.GetEval。

要返回值，只需return在传递给execute_script()方法的字符串中使用JavaScript关键字，例如

>>> from selenium import webdriver
>>> wd = webdriver.Firefox()
>>> wd.get("http://localhost/foo/bar")
>>> wd.execute_script("return 5")
5
>>> wd.execute_script("return true")
True
>>> wd.execute_script("return {foo: 'bar'}")
{u'foo': u'bar'}
>>> wd.execute_script("return foobar()")
u'eli'
