How can I handle an alert with GhostDriver via Python?
A simple solution is to rewrite the window.alert method to output the argument to a global variable.
Define the js injection variable with your override function:
js = """window.alert = function(message) {lastAlert = message;}"""
And then just pass the js variable through the execute_script call in python like this:
driver.execute_script("%s" % js)
Then when it's all been run you can execute a return on the global lastAlert:
driver.execute_script("return lastAlert")
This is some workaround.
Use this for every reloaded page that would have an alert later.
driver.execute_script("window.confirm = function(){return true;}");
This works for PhantomJS within Selenium/Splinter.
