Question

我刚刚开始学习一些Selenium脚本（在Java中）。目前我正试图在Facebook上打开聊天框并发送消息我已经能够通过selenium打开聊天框，但是我无法弄清楚如何在文本框中输入内容。
目前这是我的代码：

import org.openqa.selenium.*;
import org.openqa.selenium.chrome.ChromeDriver;

public class practice {
    public static void main(String[] args) throws InterruptedException {
      System.setProperty("webdriver.chrome.driver", "C:/max/chromedriver.exe");

      WebDriver driver = new ChromeDriver();
      driver.get("http://facebook.com/login/");
      driver.manage().window().maximize();
      driver.findElement(By.name("email")).sendKeys("myemail@yahoo.com");
      driver.findElement(By.name("pass")).sendKeys("myPassword");
      driver.findElement(By.id("loginbutton")).click();
      driver.findElement(By.name("mercurymessages")).click();
      driver.findElement(By.cssSelector("a[href*='https://www.facebook.com/messages/conversation-8148306']")).click();
     // This has worked randomly. Sometimes the driver will work and open the chat box. Sometimes it will say element not found. I didn't include the full link of the conversation because apparently you don't have to. And it has worked like this in the past.
}
}

我当前要解决的问题是：为什么这只会有效，我如何在聊天框中找到文本框区域？我做了一个Inspect Element，聊天框很奇怪。它没有像id或name这样的东西，所以我不能做By.id或By.name。我无法弄清楚如何使用By.cssSelector来做到这一点。这就是文本框的inspect元素：

textarea class="uiTextareaAutogrow _552m" data-ft=".... more stuff here" onkeydown=" more stuff here" style= "more stuff here."

Answer 1

你必须学习Xpath以及如何创建相对xpath。textarea的xpath

driver.findElement(By.xpath("//textarea[@class='uiTextareaAutogrow _552m']"));

无论如何，我做了一些改动，包括而不是点击其他消息。它会创建一条新消息并发送给你的朋友

driver.findElement(By.name("mercurymessages")).click();

    //wait for 20 seconds 
    WebDriverWait wait = new WebDriverWait(driver, 20);
    wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("u_0_5")));
    driver.findElement(By.id("u_0_5")).click();//To click on Send a New Message Link

    //To enter a name into the to field 
    wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//input[@class='inputtext textInput']")));
    WebElement friendName = driver.findElement(By.xpath("//input[@class='inputtext textInput']"));

    friendName.sendKeys("Deep");//Change it with your friend name

    //wait for the user list to appear
    wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath("//li[@class='user selected']")));
    friendName.sendKeys(Keys.ENTER);

    WebElement messageBox = driver.findElement(By.xpath("//textarea[@class='uiTextareaAutogrow _552m']"));
    wait.until(ExpectedConditions.visibilityOf(messageBox));
    messageBox.sendKeys("Hi there");

    messageBox.sendKeys(Keys.ENTER);

嗨，朋友希望这会帮助你：

有一个名为By.className的方法，所以为了找到没有id或名称的元素，你可以使用这个方法，它有时候是元素的类名，它是＆＃39;用于其他元素，所以要注意当前页面中的用法，如果你很幸运，并且类名是唯一的，那么你可以使用它：）

System.setProperty("webdriver.chrome.driver", "C:/max/chromedriver.exe");

      WebDriver driver = new ChromeDriver();
      driver.get("http://facebook.com/login");
      driver.manage().window().maximize();
      Thread.sleep(5000);
      driver.findElement(By.name("email")).sendKeys("myemail@yahoo.com");
      driver.findElement(By.name("pass")).sendKeys("myPassword");
      driver.findElement(By.id("loginbutton")).click();
      Thread.sleep(5000);
      driver.findElement(By.name("mercurymessages")).click();
      Thread.sleep(7000);// here you have to use ExpectedConditions in order to verify that the elemnt  it´s "clickable"


      driver.findElement(By.cssSelector("a[href*='https://www.facebook.com/messages/conversation-8148306']")).click();

          Thread.sleep(5000);
      WebElement mssgbox = driver.findElement(By.cssSelector("textarea[class*='uiTextareaAutogrow _552m']"));
      mssgbox.click();
        mssgbox.sendKeys("hi");

希望这对你有所帮助。

并且页面中的某些元素会发生变化，因此请使用ExpectedConditions确保页面上的元素

// Find Username and Enter

                .click();

        Thread.sleep(2000);

        driver.findElement(By.xpath("//*[@class='_1mf _1mj']//following :: div[11]")).click();
        Thread.sleep(2000);
        WebElement sendmsg = driver
                .findElement(By.xpath("//div[@class='_1ia']/descendant::div[@class='_5rpu' and @role='combobox']"));
        sendmsg.sendKeys("Just testing: using selenium webdriver" + Keys.ENTER);
