如何使用Xpath for JavascriptExecutor（Selenium）向Webelement写入路径

Question

Trying to write autotest on Selenium WebDriver. Having on page Webelement with CSS locator:

@FindBy (css = "#FeedbackMessage")
protected WebElement fm;

Also have following working method of focusing out of this element:

public void focusout(){
JavascriptExecutor js = (JavascriptExecutor) driver;

js.executeScript("arguments[0].blur();", fm);

The question is how to do same but with xpath locator usage. The xpath of an element is //textarea[@id='FeedbackMessage'] .

Trivial usage

@FindBy (xpath = "//textarea[@id='FeedbackMessage']")
protected WebElement fm;

is NOT working

Answer 1

Actually found an answer by debugging in IDEA.

@FindBy (xpath = "//textarea[@id='FeedbackMessage'][1]") protected WebElement fm;

The reason - xpath locator //textarea[@id='FeedbackMessage'] can provide list of elements (even if i have only one element). but usage of CSS or ID selector always takes first found element.

So I just needed to indicate index of element
