Basically, when an alert is popped up in javascript, I can dismiss()
it from python perfectly OK, by calling selenium.webdriver.common.alert.Alert(browser).dismiss()
.
However, if the "browser user" dismisses the alert by clicking [OK]
(on screen) with their mouse, then the browser alert gets "Lost in Space" the body.text
can no longer be accessed from python.
So... How do I recover the "text" from the page originating the alert, esp after the human user has clicked [dismiss] on the page's alert?
Here are the hints and a script to demonstrate the problem...
FYI: The objective of the originating code is it allow the browser user intervene on screen in testing and manually response to specific alerts.
#!/usr/bin/env python
import os,sys,time
import selenium.webdriver
import selenium.webdriver.support.expected_conditions
print dict(python=sys.version,selenium=selenium.__version__)
path=os.path.join(os.getcwd(),"hello_worlds.html")
url="file:///"+path
open(path,"w").write("""<HTML>
<HEAD><TITLE>Head Title</TITLE></HEAD>
<BODY><H1>Hello, worlds!</H1></BODY>
</HTML> """)
browser=selenium.webdriver.Firefox()
browser.get(url)
body=browser.find_element_by_tag_name("body")
print "BODY:",body.text
try:
for enum,world in enumerate("Mercury Venus Earth Mars Asteroids Jupiter Saturn Uranus Neptune".split()):
if "Earth" in world: world+=": So do MANUALLY dismiss! {Click [OK] now!!!}"
else: world+=": AUTO PILOT... please DONT dismiss! {done via selenium.dismiss()!}"
browser.execute_script('alert("Hello, %s!")'%world)
if selenium.webdriver.support.expected_conditions.alert_is_present():
print selenium.webdriver.common.alert.Alert(browser).text
time.sleep(enum+5)
if "Earth" not in world: selenium.webdriver.common.alert.Alert(browser).dismiss()
print "BODY:",body.text
finally:
browser.quit()
Output: (Crash at Earth)

Message: Unexpected modal dialog (text: Hello, Earth: So do MANUALLY dismiss! {Click [OK] now!!!}!) The alert disappeared before it could be closed.
The strange thing is that if the browser user triggers another alert (on another page even!), then a selenium.dismiss()
will pull body.text
back from limbo and selenium with from then will operate as per (my) expectations.
Any suggestions on how to get the browser back to the page.body
? (And escape the alert)
