步骤定义Java-Selenium WebDriver从搜索结果查找元素

Question

我是使用Java的Selenium Webdriver自动化的新手，并且还在学习中。

在我的步骤定义RetailTakePayment.java类中，我试图查找包含文本出现在搜索结果（弹出窗口）中的特定元素，但由于某种原因我无法找到并单击它。我到处找了找，运气不太好。因此，张贴我的问题，以寻求一些指导。

希望这些能帮上忙。

@Given("^user complete payment precheck$")
    public void user_complete_payment_precheck() throws Throwable {

        // inserting installer and preferred date
        driver.findElement(By.id("page:frm:main:jobsInfo:jobsRepeat2:0:j_id164")).sendKeys("Test");
        driver.findElement(By.xpath("/html/body/div[1]/div[2]/table/tbody/tr/td[2]/form/div[1]/div/div/div/div[2]/div[5]/div[2]/table/tbody/tr[1]/td/table/tbody/tr/td[4]/span/span")).click();

        // searching and selecting vehicle
        // click on lookup
        driver.findElement(By.xpath("//img[@alt='Vehicle Lookup (New Window)']")).click();
        Thread.sleep(2000);

        // window switch handler    
        String parentWindowHandler = driver.getWindowHandle();
        String subWindowHandler = null;

                Set<String> handles = driver.getWindowHandles();
                Iterator<String> iterator = handles.iterator();
                while (iterator.hasNext()) {
                    subWindowHandler = iterator.next();
                }
                driver.switchTo().window(subWindowHandler);

        // switch by frame
        driver.switchTo().frame(0);

        // searching - this worked!!!
        driver.findElement(By.xpath("//form[@id='theForm']/div/div[2]/input")).sendKeys("autod2018");
        Thread.sleep(1000);
        driver.findElement(By.name("go")).click();
        Thread.sleep(2000);

        // searching for vehicle - STILL NOT WORKING....
        driver.findElement(By.xpath("//div[contains(text(),'BMW-1 SERIES-AUTOd2018')]")).click();      
        // driver.findElement(By.xpath("/html/body/div[1]/div[3]/div/div/div[2]/div/div[2]/table/tbody/tr[2]/th/a")).click();

        // switching back to the parent window - works!
        driver.switchTo().window(parentWindowHandler);

        // save record
        driver.findElement(By.xpath("/html/body/div[1]/div[2]/table/tbody/tr/td[2]/form/div[1]/div/div/div/div[1]/table/tbody/tr/td[2]/input[1]")).click();


    }

Answer 1

因为搜索表单和结果表在不同的框架中，所以需要切换到相应的框架，然后再与框架中的元素进行交互。

 // switch to search form frame
 driver.switchTo().frame(0);

 // enter search keywords and click go
 ...

 // switch back to topmost frame in the current window.
 // this is very important, you can't directly switch to result table frame
 // from search form frame ( because it's not includes the result table frame).
 // Most of time, we back to the top frame, then jump into other frame.
 driver.switchTo().defaultContent();

 // then switch to result table frame
 driver.switchTo().frame(<index_or_name_of_result_table_frame>);
