Question

对于附加的程序文件，我面临着附加类的问题。该行代码失败

CSS：

<a class="btn btn--action btn--block" data-dojo-attach-point="sign_in_button" data-dojo-attach-event="onclick: _onSignInClicked" tabindex="2">Verify</a>

因此我的代码是：

drive.findElement( By.cssSelector(".btn.btn--action.btn--block")).click();

但我一直在控制台中收到此错误：

CODE：

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class WebFlock {

    public static void main(String[] args) throws Exception {
        //open flock.co on chrome
        WebDriver drive;
        String url = "https://flock.co/?";
        System.setProperty("webdriver.chrome.driver", "C:\\Automation\\chromedriver_win32\\chromedriver.exe");
        drive = new ChromeDriver();
        drive.get(url);
        Thread.sleep(5000);

        //find the email text box, enter email and click submit 
        drive.findElement(By.cssSelector("Input[placeholder ='Enter your work email']")).sendKeys("me@farzanshaikh.com");
        drive.findElement(By.cssSelector("button[type='submit']")).click();

        Thread.sleep(8000); //wait for loader to resolve

        drive.findElement( By.cssSelector(".btn.btn--action.btn--block")).click();

    }

}

Answer 1

请尝试以下代码：

drive.switchTo().frame(drive.findElement(By.cssSelector("#dijit__WidgetsInTemplateMixin_0 > iframe")));

        WebDriverWait wait = new WebDriverWait(drive,15);

        wait.until(ExpectedConditions.presenceOfElementLocated(By.cssSelector("a.btn")));

        drive.findElement( By.cssSelector("a.btn")).click();

<强>解释

元素存在于<iframe>;因此，为了获得该元素，我们首先需要使用iframe方法切换到.switchTo.frame()。
