onchange event does not get fired on selenium type command

Question

I am typing some value, on change do a total. But somehow, this event is not getting fired with selenium type command.

I also tried typeKey and typeAt ..But no success. Any workaround for this ?

Answer 1

To trigger the onchange event, try adding this command in Selenium IDE:

fireEvent targetID blur

Answer 2

Firefox has a bug which prevents some events from being executed while the browser window is out of focus. This could be an issue when you're running your automation tests - which might be typing even if the window is out of focus.

To fix this issue I triggered the change event "manually", injecting javascript into my tests.:

//suppose "element" is an input field
element.sendKeys("value");
JavascriptExecutor jsExecutor = (JavascriptExecutor) driver;
jsExecutor.executeScript("$(arguments[0]).change();", element);

As you might have noticed, I'm using jQuery to trigger the change event. If you're not using jQuery on your app, you can check here how to trigger it using vanilla javascript.

Hope that helps somebody.
