If I understand your question right, you want to upload a file there, is that correct? This should do the trick:

d.findElement(By.id("fileField")).sendKeys("C:\\absolutePath\\toYour\\file.jpg");

The idea is to directly send the path to the file to an element which you would usually click at to get the modal window - that is <input type='file' /> element.

Because most of those file upload inputs have some onchange event trigger, you should be able to fire those. According to WebDriver FAQ, there is a simple solution for this so you don't have to fire all those events manually:

WebDriver leaves the focus in the element you called "sendKeys" on. The "onchange" event will only fire when focus leaves that element. As such, you need to move the focus, perhaps using a "click" on another element.

on that input type file, there is a javascript call "onChange". if i run your code, it will set the path in the input but don't load the method onChange, suggest?

Petr Janeček Over a year ago

I was pretty sure that the call would trigger. But since this is a nicely done js, you can call it manually: (JavascriptExecutor)d.executeScript("onChangeFileBrowse('fileField')");

i'm trying in this site : www3.subito.it/ai/form/0 so i try ((JavascriptExecutor)d).executeScript("showSpindle();submitImage(image);"); but it returns me: Exception in thread "main" org.openqa.selenium.WebDriverException: null (WARNING: The server did not provide any stacktrace information)

Petr Janeček Over a year ago

That's a different one :). Do showSpindle(); submitImage(document.getElementById('image'));

I just found a general solution to this - I will edit it into the answer.
