Problem: Using selenium+phantomjs to simulate login, the web page pops up a box with alert(“login successful”) in JavaScript, but with switch_to_alert().accept() it reports an error and cannot execute the command.

Target code: <script language=”javascript”>alert(‘********************’);</script>

Error displayed:

Pop123= Pop_up.text
File “C:\Python27\lib\site-packages\selenium\webdriver\common\alert.py”, line 69, in text

Other Solutions:

phantomjs is no interface, can not j parse dynamic JS, so for alert is also unable to pop up directly, so phantomjs to the function callback in page in the execution of the alert event.

python does not correspond to the phentomjs special library, so you need to call JS.

python selenium officially no longer provides support for phentomjs. Now the main Firefox browser and Google Chrome browser, please try to change

I. python call Js

r = driver.execute_script(“return newsJason”)

print r

Second, Js inside the method time is busy not to test the right and wrong

page.onAlert = function(msg) {}

driver.execute_script(“window.confirm = function(msg) { return true; }”);
