无法使用 Selenium Java 在网页上输入文本以输入类型

【问题标题】：Unable to enter text to input type on Webpage using Selenium Java无法使用 Selenium Java 在网页上输入文本以输入类型
【发布时间】：2020-10-27 15:10:36
【问题描述】：

在这里上传了我的测试失败的整个网页：https://drive.google.com/file/d/1WHcwpQFi5Cxh1q1MupQEuSPk6CPZs2GC/view?usp=sharing

以下是 Selenium Recorder IDE 插件自动生成的 Selenium Java 代码，我试图在我的网页上输入文本以输入类型。

driver.findElement(By.id("crtestrequest-cr_app_name")).click();
driver.findElement(By.id("crtestrequest-cr_app_name")).clear();
driver.findElement(By.id("crtestrequest-cr_app_name")).sendKeys("Allocation");

以上没有工作和错误。因此，我对我的代码进行了以下更改：

以下代码间歇性地工作，但很少工作。

js.executeScript("arguments[0].click();", driver.findElement(By.id("crtestrequest-cr_app_name")));
System.out.println("Title of the page is 7.19 -> " + driver.getTitle());
driver.findElement(By.id("crtestrequest-cr_app_name")).clear();
System.out.println("Title of the page is 7.20 -> " + driver.getTitle());
driver.findElement(By.id("crtestrequest-cr_app_name")).sendKeys("Allocation");
System.out.println("Title of the page is 7.21 -> " + driver.getTitle());

我在运行测试时遇到以下错误：

Title of the page is 7.18 -> Raise CR Request
Title of the page is 7.19 -> Raise CR Request
Title of the page is 7.20 -> Raise CR Request

你能建议我如何让它工作吗？

【问题讨论】：

  • 你试过Class Actions？
  • 是的，但它不起作用...更新了原帖中Actions类的错误。

标签： java selenium xpath css-selectors webdriverwait


【解决方案1】：

我在过去 24 小时内一直在努力让它发挥作用，最终做到了。

之前，我触发了Search Assests 按钮，在我的视频中可见@ 1.11 分钟，我尝试了下面的代码。

WebElement ele = driver.findElement(By.id("crtestrequest-cr_app_code"));
JavascriptExecutor exec = (JavascriptExecutor)driver;
exec.executeScript("arguments[0].click();", ele);
driver.findElement(By.id("crtestrequest-cr_app_code")).clear();
driver.findElement(By.id("crtestrequest-cr_app_code")).sendKeys("Allocation");

【讨论】：

    【解决方案2】：

    您需要在 &lt;input&gt; 元素上调用 sendKeys() 而不是调用 &lt;label&gt;，理想情况下是在您需要的元素上调用 click()将WebDriverWait 用于elementToBeClickable()，您可以使用以下任一Locator Strategies：

    • cssSelector:

      WebElement element = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("div.row div.field-crtestrequest-cr_app_name>label[for='crtestrequest-cr_app_name']")));
element.click();
element.clear();
element.sendKeys("Allocation");

    • xpath:

      WebElement element = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//div[@class='row']//div[contains(@class, 'field-crtestrequest-cr_app_name')]/label[@for='crtestrequest-cr_app_name']")));
element.click();
element.clear();
element.sendKeys("Allocation");

    您可以在ElementNotInteractableException 上找到一些相关讨论：

    【讨论】：

    • 我试过你的建议，但还是不行。使用您的建议输出@DebanjanB 更新了原始帖子
    • @Ashar 查看更新的答案并告诉我状态。
    • 我在编译您的更新建议@DebanjanB 时遇到了一些问题。 1. 元素对象被定义了两次... 2. error: incompatible types: inference variable V has incompatible bounds 。您能否更正代码，因为我不确定？
    • @Ashar 查看更新的答案并告诉我状态。
    • 不起作用@DebanjanB 我猜是由于在输入之前的弹出操作可能是问题的原因。在我回到主窗口之前，请看这里 1:11 分钟的视频 youtu.be/-Lk6_SgRkpk?t=71 以了解弹出操作。是否可以选择让焦点控制回到主窗口？
    【解决方案3】：

    我认为你需要的元素存在于 DOM 中，但它不是处于可以与它们交互的状态。

    WebDriverWait wait = new WebDriverWait(driver, 10);
wait.ignoring(StaleElementReferenceException.class).until(ExpectedConditions.elementToBeClickable(By.id("crtestrequest-cr_app_name")));
WebLement input = driver.findElement(By.id("crtestrequest-cr_app_name"))
input.click();
input.clear();
input.sendKeys("123");

    或

    for(int i=0; i<=2;i++){
  try{
     WebLement input = driver.findElement(By.id("crtestrequest-cr_app_name"))
     Actions actions = new Actions(driver);
     actions.moveToElement(input).perform();
     input.click();
     break;
   } catch (StaleElementReferenceException e) {
           System.out.println("Trying to recover from a stale element :" + e.getMessage());
   }
}

    【讨论】：

    • 我试过你的建议，但还是不行。用您的建议输出更新了原始帖子@Norayr Sargsyan
    • @Ashar 如果你能提供你测试的 URL 和你想要交互的元素，我会把解决方案发给你
    • 请在我的原始帖子中找到更新的错误，尝试您的建议。我可以尝试上传整个网页，但这是一个内部网页。此外，复制粘贴网页的整个视图源会扭曲外观，但我可以尝试分享。
    • @Ashar 我已经更新了我的答案，请检查并告诉我
    • 通过您建议的此更改，即wait.ignoring，我收到与您的建议在 OP 中所述相同的错误。关于Actions 解决方案，您是如何在element.click() 中获得element 的？你能为Actions写完整的解决方案吗？
