我一直在尝试使用webdriver从下拉列表框中选择项目，但无法在此成功。
情景将是这样的：
HTML剪辑集如下：
![<tr>
<td class="formfield">`enter code here`

答案 0 :(得分：0)
请使用以下代码从下拉列表中选择特定值：
public void finddata(String Text) {
wait.until(ExpectedConditions.presenceOfElementLocated(By.id("ctl00_M_PR_6_T2_CPLGx2_ddCountryDep")));
driver.findElement(By.id(Text)).click();
Select sel = new Select(driver.findElement(By.id("ctl00_M_PR_6_T2_CPLGx2_ddCountryDep")));
sel.selectByVisibleText("Albania");
}
您也可以使用xpath，cssselector来查找元素。
答案 1 :(得分：0)
检查元素，复制xpath并使用xpath解决问题
修复步骤：
使用浏览器google chrome， 右键单击元素并选择inspect元素， 使用右键单击复制选定的元素xpath - ＆gt;复制Xpath和 在代码中使用xpath表达式
答案 2 :(得分：0)
我建议您使用cssSelector并使用适当的等待时间。
public void SelectCountryByValue(string country)
{
By byValue = By.CssSelector("#ctl00_M_PR_6_T2_CPLGx2_ddCountryDep > option[value='" + country + "']");
new WebDriverWait(Driver, TimeSpan.FromSeconds(10)).Until(ExpectedConditions.ElementExists(byValue));
var country = new SelectElement(Driver.FindElemenet(byValue));
country.SelectByValue(companyCode);
}
注意：用C＃编写但语法并将其转换为java应该非常相似

好奇......在尝试在弹出窗口中找到元素之前，您是否已检查webdriver是否已切换到弹出窗口。如果不是，您可能需要执行类似
popup = driver.switchTo().window(windowHandle);
然后，尝试找到元素。
