       WebDriver d = new PhantomJSDriver(caps); 

//WebDriver d=new HtmlUnitDriver();
        WebDriverWait wait = new WebDriverWait(d, 10);
        d.get("https://www.gmail.com/intl/en/mail/help/about.html");
        System.out.println("navigated to gmail");
        d.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

        /*String keysPressed =  Keys.chord(Keys.CONTROL, Keys.RETURN);

         d.findElement(By.xpath("html/body/div[14]/div/div/div/div[1]/div[3]/div[1]/div[1]/div/div/div/div[3]/div/div/div[4]/table/tbody/tr/td[2]/table/tbody/tr[2]/td/div/div/div[4]/table/tbody/tr/td[1]/div/div[2]")).click();
        System.out.println("Clicked On send");

Answer 1

我发现问题出在我使用JARphantomJSDriver-1.1.0的jar上。jar我现在已经更改了jar的版本，即phantomjsdriver-1.2.1。这个罐子很好用

谢谢朋友们的帮助

Answer 2

请试试这个，我希望它能帮助您，为什么您要使用这么长的XPATH，它必须从html中遍历

 d.findElement(By.xpath(".//tr[@class='n1tfz']/td[1]/div[1]/div[2]")).click();
