无法在Java Selenium中选择Bootstrap下拉列表

Question

我在Selenium选择bootstrap下拉时非常困难.

我是Selenium的新手,所以任何建议和指导都会非常有用,因为我喜欢做的只是选择下拉列表,输入"email",然后在实例中按Enter键.

我已经完成了几十个解决方案,但没有一个能够解决这个问题.

我能做什么？请帮忙.

    //Select from dropdown

这是数据文件ufile.io/vy2ws的链接

要使.CSV文件上载起作用,您必须运行此软件的本地版本.可以在此处找到下载:https://www.mautic.org/m/asset/54:mautic-2100

上传后,它应该看起来像是要求从下拉列表中选择.

更换:

WebElement dropdownToggle = driver.findElement(By.xpath("id('lead_field_import_email_add??ress')")); 

对此:

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

更换

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

同

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

Answer 1

查看HTML您提供的，WebElementwithid="lead_field_import_email_address"是Select标签中的 with 。因此，Actions在这种情况下，我们应该尝试使用 Class，而不是使用SelectClass，如下所示：

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

接下来，我们可以options通过调用selectByIndex(n),selectByValue("value")或selectByVisibleText("visible_text")方法来选择其中的任何一个。
