按钮未在Selenium中标识

Question

我试图点击一个按钮，这是非常可见的屏幕上，但硒webdriver抛出这个错误

我试图验证的按钮有html标签如下:

<input id="loginbutton" type="submit" name="loginbutton" value="" onclick="clkLgn()" style="width: 59px; height: 20px"></input>

到目前为止我的基本代码:

WebDriverWait wait = new WebDriverWait(driver, 10);
             WebElement BTN = wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("#loginbutton")));
             BTN.sendKeys(Keys.RETURN);

所以这是我上面问题的解决方案。我用Javascript点击了按钮a

JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("document.getElementById('loginbutton').click();");
