org.openqa.selenium.NoSuchElementException WebDriver是否在Java中？

Question

I have a problem with WebDriver Java class, when I want to get an attribute type "textArea"

I get this Exception.

Code:

WebDriver driver = new HtmlUnitDriver();
driver.get("http://www.cmmazzoni.it/index.php?option=com_jdownloads&Itemid=0&view=upload");
WebElement descriptionOne=driver.findElement(By.name("description"));
descripcionUno.sendKeys("Hola! :D");

Exception:

java.lang.UnsupportedOperationException: You may only set the value of elements that are input elements
    at org.openqa.selenium.htmlunit.HtmlUnitKeyboard.sendKeys(HtmlUnitKeyboard.java:82)
    at org.openqa.selenium.htmlunit.HtmlUnitWebElement.sendKeys(HtmlUnitWebElement.java:343)

Answer 1

The reason it ain't working is cause the element where u need to enter text is in a iframe. Please try out following code:

driver.switchTo().frame(
        driver.findElements(By.tagName("iframe")).get(0));
WebElement descriptionOne = driver
    .findElement(By.className("editbox"));
descriptionOne.sendKeys("Hola! :D");

Answer 2

As per your code, you are calling wrong webElement name to sendkeys:

WebDriver driver = new HtmlUnitDriver();
driver.get("http://www.cmmazzoni.it/index.php?option=com_jdownloads&Itemid=0&view=upload");
WebElement descriptionOne=driver.findElement(By.name("description"));
descripcionUno.sendKeys("Hola! :D");

Please use "descriptionOne.sendKeys("Hola! :D");" instead of "descripcionUno.sendKeys("Hola! :D");"

Let me know if it works for you. Cheers!
