无法在Java Selenium中选择引导程序下拉列表

问题描述：

我在Selenium中选择引导程序下拉列表非常困难。无法在Java Selenium中选择引导程序下拉列表

我是新来的Selenium，所以任何建议和指导都会非常有帮助，因为我喜欢做的只是选择下拉列表，然后输入“email”，然后在实例中按回车键。

我已经经历了几十种解决方案，但他们都没有为这个特定的问题工作。

我该怎么办？请帮忙。

为了使.csv文件上传工作，你必须是运行本软件的本地版本。可以在这里找到下载：https://www.mautic.org/m/asset/54:mautic-2100

一旦上传，它应该看起来像这样它要求从下拉列表中选择。

HTML

<div class="col-sm-4">

更换：

WebElement dropdownToggle = driver.findElement(By.xpath("id('lead_field_import_email_add‌ress')"));

这样的：

WebElement dropdownToggle = driver.findElement(By.id("lead_field_import_email_address"))‌;

你能分享你的Selenium代码吗？另外，你能否格式化你的HTML代码，对齐它，如果可能的话，只需要对你的问题重要的部分？ – Tom

你可以发布你的代码到目前为止你尝试了什么所以我们可以指出你的代码有什么问题。如果可能的话，请分享该网站的URL – NarendraR

我更新了代码，使其更加简单直接。我正在使用的链接是https://demos5.softaculous.com/Mautic/s/contacts/import/new – JamesRocky

看着你所提供的HTML，该WebElement与id="lead_field_import_email_address"是在Select标签。因此，而不是在这种情况下使用Actions类，我们应该尝试使用Select类代替如下：

WebElement element = driver.findElement(By.id("lead_field_import_email_address")); 
Select select = new Select(element);

接下来，我们可以通过调用任何selectByIndex(n)，selectByValue("value")或selectByVisibleText("visible_text")方法选择任何options的。

它好像当我尝试并执行它，它不会选择 – JamesRocky

@JamesRocky我的回答是，以帮助您选择类。它必须没有任何失败的工作。你想选择哪个选项？你看到什么错误？你能用你当前的代码和完整的错误堆栈跟踪来更新问题吗？ – DebanjanB

我已更新帖子。感谢您的帮助。 – JamesRocky

我试图手动复制你的代码的步骤，但是当我加载data_file.csv和我点击上传按钮：

没有任何反应。

而且，在HTML中，有没有你试图找到元素：

WebElement dropdownToggle = driver.findElement(By.xpath("id('lead_field_import_email_address')"));

这就是为什么我写了this comment。

我可以想象应该打开一些东西。从信息：

限制
分隔符
外壳
逃生

我可以假设你要上传的文件与一个特定的格式。

编辑

本地尝试它的作品。如果你想从电子邮件下拉列表选择

 //Select from dropdown 
     WebElement dropdownToggle = driver.findElement(By.xpath("id('lead_field_import_email_address')")); 
     Actions cursor = new Actions(driver); 
     cursor.moveToElement(dropdownToggle); 
     cursor.click(); 
     cursor.perform(); 
     Thread.sleep(1000); 
     WebElement weh = driver.findElement(By.id("lead_field_import_email_address_chosen")); 

     Actions cursor2 = new Actions(driver); 
     cursor2.moveToElement(weh); 
     cursor2.click();

，你可以使用XPath：我不明白你的好这部分代码

WebElement we = driver.findElement(By.xpath("//div[@class='choice-wrapper']//div[@id='lead_field_import_email_address_chosen']"));

或简称ID：

WebElement we= driver.findElement(By.id("lead_field_import_email_address_chosen"));

并执行感兴趣的操作。

因此，举例来说：

WebElement we= driver.findElement(By.id("lead_field_import_email_address_chosen")); 
    we.click(); 
    we.sendKeys("email"); 
    we.sendKeys(Keys.ENTER);

EDIT 2

你的问题是，你为了等待的元素中使用Thread.sleep(XXXX);。这不是确定性的。您必须使用明确的等待。

从Explicit Waits：

一个明确的等待是你定义等待某个条件代码，然后再继续发生代码。的极端情况是time.sleep（），它将条件设置为准确的时间段等待。有一些便利的方法可以帮助你编写只会根据需要等待的代码。 WebDriverWait在与ExpectedCondition的组合是可以实现的的一种方式。

所以，在Java中，你需要：

这最多等待15秒抛出一个TimeoutException除非它找到的元素返回前：
WebDriverWait wait = new WebDriverWait(driver, 15); 
WebElement we=wait.until(ExpectedConditions.elementToBeClickable(By.id("lead_field_import_email_address_chosen"))); 
从以前的链接
始终在15秒内。 WebDriverWait 默认每500毫秒调用一次ExpectedCondition，直到它成功返回。 ExpectedCondition成功返回类型为布尔值返回值为true或非null返回值为所有其他 ExpectedCondition类型。

最后，整个代码：

 String geckoDriver = System.getProperty("pathTo/geckodriver"; 
     System.setProperty("webdriver.gecko.driver", geckoDriver); 
     WebDriver driver= new FirefoxDriver(); 
     driver.get("http://localhost:8888/2.10.0/s/contacts/import/new"); 
     driver.findElement(By.id("username")).sendKeys("admin"); 
     driver.findElement(By.id("password")).sendKeys("password"); 
     driver.findElement(By.className("btn")).click(); 

     WebDriverWait wait = new WebDriverWait(driver, 15); 

     WebElement uploadBox=wait.until(ExpectedConditions.elementToBeClickable(By.id("lead_import_file"))); 
     uploadBox.sendKeys("/pathTo/data_file.csv"); 
     driver.findElement(By.id("lead_import_start")).click(); 

     //Select from dropdown 
     WebElement we=wait.until(ExpectedConditions.elementToBeClickable(By.id("lead_field_import_email_address_chosen"))); 
     we.click(); 
     we.sendKeys("email"); 
     we.sendKeys(Keys.ENTER);

EDIT 3

与Firefox，上面的代码（在我的测试）是确定。我注意到你使用Chrome。使用Chrome，我有this problem。 solution适合我：

 //Select from dropdown 
     WebElement we=wait.until(ExpectedConditions.elementToBeClickable(By.id("lead_field_import_email_address_chosen"))); 
     /*we.click(); 
     we.sendKeys("email");*/ 

     Actions actions = new Actions(driver); 
     actions.moveToElement(we); 
     actions.click(); 
     actions.sendKeys("email"); 
     actions.sendKeys(Keys.ENTER); 
     actions.build().perform();

嗨，感谢您的评论。我只注意到上传.CSV文件不起作用。我实际上正在运行该服务的本地版本，它应该工作。你可以在这里下载软件并在本地运行：https://www.mautic.org/m/asset/54:mautic-2100 – JamesRocky

@JamesRocky我刚刚编辑了答案。 –

这有效吗？我已经试过这个，可悲的是它没有导致下拉选择，并给出了这个错误“线程中的异常”主要“org.openqa.selenium.NoSuchElementException：没有这样的元素：无法找到元素：{”method“ ：“xpath”，“selector”：“// div [@ class ='choice-wrapper'] // div [@ id ='lead_field_import_email_address_chosen']”}' – JamesRocky
