无法使用 Selenium Java 在网页上输入文本

已将我的整个网页上传，但测试失败： https://drive.google.com/file/d/1WHcwpQFi5Cxh1q1MupQEuSPk6CPZs2GC/view?usp=sharing

下面是 Selenium Recorder IDE 插件自动生成的 Selenium Java 代码，我试图在网页上输入文本。 

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");

以上操作无效，并出现错误。因此，我对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());

我在运行测试时收到以下错误： 

Title of the page is 7.18 -> Raise CR Request

这是来自网页的文本输入的相关查看源代码： 

<div class="row"><div class="col-lg-12"></div></div>
<div class="row"><div class="col-lg-12"></div></div>

<div class="row"><div class="col-lg-12"><div class="form-group col-lg-6 field-crtestrequest-cr_app_name required">

您能建议我如何让它工作吗？

3个回答

我在过去 24 小时内一直在尝试让它工作，最后终于成功了。

之前，我触发了 Search Assests 按钮，如我的视频中所示，@1.11 分钟我尝试了下面的代码，它起作用了。 

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");

我认为您需要的元素存在于 DOM 上，但它不处于您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());
   }
}

您不需要对 <label> 调用 sendKeys() ，而是需要在 <input> 元素上调用，最好对元素调用 click() ，您需要对 elementToBeClickable() 使用 WebDriverWait ，并且可以使用以下任一方法 定位器策略 ：

  • 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");
