Question

所以我正在编写一个自动执行网页操作的程序，而我正在使用FirefoxDriver来执行此操作，但现在我可以使用HtmlUnitDriver代替。这段代码很好用：

                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);

驱动程序是这样的：

String tempStr;
String baseWinHandle;

FirefoxDriver driver = new FirefoxDriver();

WebDriverWait wait = new WebDriverWait(driver, 60);

WebElement element;

List<WebElement> inputs;

但是当我尝试更改为HtmlUnitDriver时，我遇到了定位元素的问题。首先我得到这样的错误：

: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＆＃34;等待＆＃34;我得到错误，说返回元素不是Html元素

是否有人可以帮助解决这些错误？我到处搜索，无法找到答案。

Selenium java - HtmlUnitDriver查找元素
