无法识别 IE9 的 Selenium webdriver 中的元素

Question

我无法使用 Selenium webdriver 识别页面中的任何 web 元素。使用 2.48.0 硒罐。我尝试过 xpath 绝对路径、相对路径、css 选择器、id、名称。全部抛出 NoSuchElementException。我被困在这里。请帮我。我可以轻松登录应用程序登录后选择菜单项将直接进入页面。在该页面上，将无法识别任何元素。

请找到我要输入的文本框 html来源：

<input class="AnswerText" type="text" onblur="$('#ind6').attr('class','ALIP-Icon sprite-icon_indicator_off'); " onfocus="gotFocus(this);$('#ind6').attr('class','ALIP-Icon sprite-icon_indicator'); removeFocus('ind6'); " maxlength="15" size="15" value="" name="7:/XML/ApplicationSummary/ContractNumber">

控制台错误错误：

Answer 1

您可以通过禁用保护模式来尝试相同的操作吗？让我们按照以下方式进行，如果您仍然面临并提供代码，我可以知道是什么问题

1. 选择 IEDriverServer.exe 32 位并使用相同
2. 取消选中安全选项卡中的所有区域
3. 如果您的答案不起作用，请尝试在另一个答案中指定的短 xpath
4. 先尝试不等待，等待，如果失败则 thread.sleep

谢谢

Answer 2

我认为存在同步问题。在开始发送值之前，我会等待该元素出现。请使用以下代码并尝试运行。它应该可以工作。

我将 xpath 替换为名称，或者您也可以尝试使用 Class。你有非常大的xpath。在我看来，有那么长是不好的。

    WebDriverWait wait = new WebDriverWait(driver, timeoutWait);
                wait.until(ExpectedConditions.visibilityOf(By.name("7:/XML/ApplicationSummary/ContractNumber"))).sendKeys("1234567")
