1)我可以使用以下命令点击标签，但无法选择该项目：
driver.FindElement(By.CssSelector("span[aria-owns='cboAccountSettings_listbox']")).Click();2)我也使用了这个代码，但是找不到特定的元素：
var LSPAccount = WebBrowser.FindElement(By.CssSelector("span[aria-owns='cboAccountSettings_listbox']"));
Thread.Sleep(1000);
var selectElement = new SelectElement(LSPAccount);
Thread.Sleep(1000);
selectElement.SelectByValue("SWO-ARG");3)我也试过了，但是没有成功：
var xpath = "//span[contains(@class,'k-widget k-dropdown k-header')][contains(@id,'cboAccountSettings')][contains(text(),'SoftwareONE ARG')]";
var admi = WebBrowser.FindElement(By.XPath(xpath));
Thread.Sleep(1000);
admi.Click();回答 2

您可以尝试执行以下操作：
//get the select html element
var selectList = driver.FindElement(By.Selector("select#cboAccountSettings"));
//wrap it inside webdriver's SelectElement and select option with value "SWO-ARG"
var selectElement = new SelectElement(selectList);
selectElement.SelectByValue("SWO-ARG");SelectElement需要表示html select的IWebElement。另外，请检查目标选择元素是否不在某个框架内。在这种情况下，首先切换到目标帧。

Select元素不可见，这就是问题所在。您可以使用javascript选择选项(Java)：
String option = "SWO-ARG";
((JavascriptExecutor) driver).executeScript("arguments[0].selected='selected';", driver.findElement(By.cssSelector("#cboAccountSettings option[value='" + option + "']")));也可以尝试这样做：
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].removeAttribute('selected');", driver.findElement(By.cssSelector("#cboAccountSettings option[selected]")));
js.executeScript("arguments[0].setAttribute('selected', 'selected');", driver.findElement(By.cssSelector("#cboAccountSettings option[value='SWO-ARG']")));页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
