Selenium Webdriver sendkeys does not trigger onchange event in IE9.0

Question

I'm writing Selenium test scripts using Java for an application built in ExtJs. I have an input field in one of the page which is attached to 'onchange' event. Whenever user modifies the text in the field, onchange event is triggered. I'm using WebDriver sendKeys() to modify the text in the field. So whenever text is modified, 'onchange' event is triggered in Firefox and Chrome (as expected) but its not getting triggered in IE9.0. I have searched all over the net for the solution, but didn't find one. So please can someone help me on this? Let me know more info is required

Accepted Answer

You can either click on a different element on the field, or perhaps the easier way is to tab off of the field after the input is finished.

In the ExtJS applications I've automated, I'll always tab off of the field after performing the input, which fires all of the correct events.

Using C# as an example:

```
IWebElement element = driver.FindElement(By.Id("some_input_field"));
element.SendKeys("test input")
element.SendKeys(Keys.Tab);
```
