java - 为日期选择器获取 ElementNotVisibleException : Using Selenium WebDriver in MakeMyTrip. com

Question

我想单击 makemytip.com 中的特定日期。我写了下面的代码。一切正常。除了我无法选择日期。我可以导航到我想要的月份，但无法选择日期。提前感谢您的帮助。

当我运行下面的程序时，出现以下错误

线程“main”中的异常 org.openqa.selenium.ElementNotVisibleException:元素当前不可见，因此可能无法与之交互

    }

        String monthYearDisplayed = d.findElement(By.xpath("//*[@id='ui-datepicker-div']/div[1]/div/div")).getText();
        System.out.println(monthYearDisplayed);

        System.out.println(monthYearToBeSelected);

        while(true){

                d.findElement(By.xpath("//a[text()='"+day+"']")).click();
                System.out.println("Found and Selected");
                break;

            }else{ //navigate to correct month and year
                if(dateToBeSelected.after(currentDate)){
                    d.findElement(By.xpath("//*[@id='ui-datepicker-div']/div[2]/div/a/span")).click();
                }else{
                    d.findElement(By.xpath("//*[@id='ui-datepicker-div']/div[1]/div/a/span")).click();
                }

            }
            monthYearDisplayed = d.findElement(By.xpath("//*[@id='ui-datepicker-div']/div[1]/div/div")).getText();
        }
    }
    }

WebElement.click() 不起作用，因为出于某种原因 WebDriver 认为 Web 元素不可见。要验证这一点，您可以执行:

WebElement dayElement = d.findElement(By.xpath("//a[text()='" + day + "']"));
System.out.println("isDisplayed: " + dayElement.isDisplayed()); //this will always print false

要绕过可见性检查，您可以通过 javascript 执行点击:

WebElement dayElement = d.findElement(By.xpath("//a[text()='" + day + "']"));
JavascriptExecutor js = (JavascriptExecutor) d;
js.executeScript("arguments[0].click();", dayElement);
