无法在使用java的Selenium Webdriver中选择复选框

我正在尝试选择一个复选框，但我无法选择，也没有在其他线程中找到任何解决方案

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();

以下是下拉列表的HTML代码：

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();

代码： @FindBy（css=“input.ngvalid.ngdirty.ng”） WebElement-chrcfee

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();

chrcfee.click（）

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();

但当我以同样的方式定义和使用时，它并不像其他复选框那样工作。我发现与其他代码相比的区别在于，这里的html代码有额外的一行

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();

请建议如何定义，以便识别

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();

获取错误： org.openqa.selenium.NoSuchElementException:没有这样的元素：无法找到元素：{“方法”：“css选择器”，“选择器”：“input.ng valid.ng dirty.ng toucted”} （会话信息：chrome=69.0.3497.92）

所需元素是一个元素，因此您必须引导WebDriverWait使该元素可单击，并且您可以使用以下任一解决方案：

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();

• css选择器

  ：

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();
  

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();
  

• xpath

  ：

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();
  

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();
  

我找到了解决方案： 我使用javascript单击该字段，效果很好，下面是代码：

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();

JavascriptExecutor js=（JavascriptExecutor）驱动程序

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();

js.executeScript（“参数[0]。单击（）；”，CamWizOR.chrgAllocFee）

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();

CamWizOR.chrlocfee->WebElement name

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();

@FindBy（xpath=“//输入[@name='ChargeAllocationFee'和@type='checkbox']”）

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();

WebElement-chrcfee

不应该是

@FindBy（css=“input.ng valid.ng dirty.ng toucted”）

？我错了，有两个类。我第一个是@FindBy（css=“input.ng valid.ng dirty.ng toucted”）web元素chrgAllocFee；错误：org.openqa.selenium.NoSuchElementException:没有这样的元素：无法找到元素：{“方法”：“css选择器”，“选择器”：“input.ng valid.ng dirty.ng toucted”}（会话信息：chrome=69.0.3497.92）这可能不相关，但为什么不使用id来查找元素？另外，您可能需要引入等待/超时，以便selenium可以检测元素的存在性。即使它不是一个动态元素，如果代码依赖于某种服务器处理，它仍然可能有一些加载问题。再说一遍，为什么不使用id来获取元素，并且您是否尝试过引入一种等待直到元素可单击的代码？仍然会出现相同的错误..尽管我发现现在类名更改了费用分配费？虽然我更改了名称，但仍然无法使用您提到的上述解决方案。

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.ng-valid.ng-dirty.ng-touched[name='ChargeAllocationFee']"))).click();

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='ng-valid ng-dirty ng-touched' and @name='ChargeAllocationFee']"))).click();
