How to type some text in hidden field in Selenium WebDriver using Java

Question

I am using WebDriver with Java for test automation. I have the following HTML code for input field which is hidden:

<input type="hidden" value="" name="body" id=":6b">

How to type something in hidden field in Selenium2 (WebDriver)? I have written code as:

driver.findElement(By.name("body")).sendKeys("test body");

But it was shown the following error: org.openqa.selenium.ElementNotVisibleException: Element is not currently visible and so may not be interacted with Command duration or timeout: 30.04 seconds

Can anybody please help me to write/type some text in hidden field?

Answer 1

First of all you have to change the value of type attribute as text from hidden. The following code using javascript would work for that:

jse.executeScript("document.getElementsByName('body')[0].setAttribute('type', 'text');");

Now, you are able to type on that text by using WebDriver. So, the overall code for typing with WebDriver using Java and Javascript as follows:

WebDriver driver = new FirefoxDriver();
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("document.getElementsByName('body')[0].setAttribute('type', 'text');");
driver.findElement(By.xpath("//input[@name='body']")).clear();
driver.findElement(By.xpath("//input[@name='body']")).sendKeys("Ripon: body text");

Answer 2

WebDriver driver=new FirefoxDriver();
driver.get("http://localhost/login.do");
driver.manage().window().maximize();
RemoteWebDriver r=(RemoteWebDriver) driver;
String s1="document.getElementById('username').value='admin'";
r.executeScript(s1);
