SeleniumJava-HtmlUnitDriver查找元素

因此，我正在编写一个程序，自动在网页上执行操作，我使用的是

FirefoxDriver

，但现在我可以真正使用

HtmlUnitDriver

。 这段代码工作得很好：

                tempStr = AutoBot.queue.get(i);
                if(k == 0)
                {
                    System.out.println(ForumDialogBS.forumURL);
                    driver.get(ForumDialogBS.forumURL);
                    baseWinHandle = driver.getWindowHandle();
                    temp = AutoBot.logDetails.get("stuff");
                    element = driver.findElement(By.className("login-window"));
                    element.click();
                    element = driver.findElement(By.name("vb_login_username"));
                    element.sendKeys(temp.getUser());
                    element = driver.findElement(By.id("navbar_password_hint"));
                    element.sendKeys(temp.getPswd());
                    element = driver.findElement(By.className("loginbutton"));
                    element.click();
                    temp.rst();
                    driver.switchTo().window(baseWinHandle);
                    k = 1;
                    pause(2);
                }
                wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("qr_preview")));
                element = driver.findElement(By.id("qr_preview"));
                element.click();
                element = driver.findElement(By.cssSelector("textarea.cke_source"));
                element.sendKeys(tempStr);
                wait.until(ExpectedConditions.visibilityOfElementLocated(By.name("sbutton")));
                element = driver.findElement(By.name("sbutton"));
                element.click();
                System.out.println((i+1) + "//" + AutoBot.toIndex);
                pause(8);

驱动程序如下所示：

String tempStr;
String baseWinHandle;

FirefoxDriver driver = new FirefoxDriver();

WebDriverWait wait = new WebDriverWait(driver, 60);

WebElement element;

List<WebElement> inputs;

:43:57 PM com.gargoylesoftware.htmlunit.DefaultCssErrorHandler error WARNING: CSS error: 'http://pornsavant.com/clientscript/vbulletin_css/style00011l/main-rollup.css?d=1415642704' [1:48457] Error in expression.

然后：

如果我删除“wait”，我会得到一个错误，说返回的元素不是Html元素

有没有人可以帮助解决这些错误？

我到处都搜索过，找不到任何答案。

尝试在顶部使用40-50秒的隐式等待，并在指定的位置丢失所有显式等待。看看这是否有效。据我所知，异常与HtmlUnitDriversaly有关，设置隐式等待而不是显式等待根本没有任何帮助，我仍然会遇到这个错误：线程“thread-5”org.openqa.selenium.NoSuchElementException中的异常：返回的节点不是HTML元素我也遇到了与HTMLUnitDriver相同的错误。用chromedriver替换HTMLUnitDriver，一切正常@苏瑞尤森你能解决这个问题吗？
