How to call a JavaScript function from within Selenium?

Question

I need to call a JavaScript function from Selenium WebDriver in Firefox. I use this command in Firebug's Command Editor to invoke a file upload application after logged into my website:

infoPanel.applicationManager.changeApp('FileUploader', {action: 'new'})

Is there a way to execute this from Selenium?

Try this:

WebDriver driver = new ChromeDriver();
((JavascriptExecutor)driver).executeScript("yourScript();");

WebDriver driver = new AnyDriverYouWant();

if (driver instanceof JavascriptExecutor)

{

((JavascriptExecutor)driver).executeScript("yourScript();");

}

When you run this after loading a page in webdriver, this javascript is added to the page and it remains there until I reload the page. Is there a way to remove this javascript from the page after executing it only once?
