如何使用Python + Selenium从警告框中读取文本

Question

I want to read the text from the alert box.

If this text is found in the alert box I have to close the alert box:

Answer 1

To read the text from the Alert Box , validate and close the Alert you have to switch to the Alert first and follow the below mentioned steps:

alert = chrome.switch_to_alert()
alert_text = alert.text
# validate the alert text
alert.accept()

However, now it seems switch_to_alert() is deprecated . So as per the current implementation you need to use:

• switch_to.alert() as follows:

   alert = driver.switch_to.alert() alert_text = alert.text # validate the alert text alert.accept() 

• As per best practices you should always induce WebDriverWait for the alert_is_present() before switching to an Alert as follows:

   from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By from selenium.webdriver.support import expected_conditions as EC # other lines of code alert = WebDriverWait(driver, 5).until(EC.alert_is_present) alert_text = alert.text # validate the alert text alert.accept() 

You can find a relevant discussion in Why switching to alert through selenium is not stable?

Answer 2

First of all, you should switch to the alert window:

alert = driver.switch_to_alert()

Then get the text on the alert window by using alert.text . And check your text for correctness.

Then do such action (close the alert window):

alert.accept()

Answer 3

I have similar situations as this in my framework as well, and this is how I solved it.

if (_driver.FindElement(By.XPath("//*[text()[contains(.,'No Sales Found')]")).Enabled)
{
     //Do Something
}

Put this after functionality that may bring the error up. Also, this example is using C# and _driver as the driver, which may be different from what you are using.

I dont know python but in java you can like this:

Alert alert = driver.switchTo().alert();
String msg=alert.getText();
if(msg.equals("Message you compare"))
{
alert.accept();
}
