单击按钮并在 Selenium java 中获取表格的大小

Question

I am trying to learn selenium to find elements and I could not clicking the "Edit"buttons and Im trying the get the size of the rows of the table.

Here is my code:

System.setProperty("webdriver.chrome.driver","C:\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
String baseUrl = "https://js.devexpress.com/Demos/WidgetsGallery/Demo/DataGrid/PopupEditing/Angular/Light/";
driver.get(baseUrl);
driver.manage().window().maximize();
TimeUnit.SECONDS.sleep(5);
List<WebElement> we = driver.findElements(By.linkText("Edit")); System.out.println(we.size());
we.get(1).click();

Here is the link that I am working: https://js.devexpress.com/Demos/WidgetsGallery/Demo/DataGrid/PopupEditing/Angular/Light/

Answer 1

driver = new ChromeDriver();
driver.get("https://js.devexpress.com/Demos/WidgetsGallery/Demo/DataGrid/PopupEditing/Angular/Light/");
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(20));
WebElement frame = wait.until(ExpectedConditions.visibilityOf(driver.findElement(By.id("demoFrame"))));
driver.switchTo().frame(frame);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("[class=\"dx-link dx-link-edit\"]"))).click();

Use webdriver wait and switchTo frame, you have to switch to iframe first to interacte elements inside the iframe.

once you finish, if you want to interact with elements outside iframe then you have to switch out of it first.

 driver.switchTo().defaultContent();
 //rest of your code

Answer 2

The element is present inside an iframe and you need to switch iframe first and then you will be able to interact with element.

To overcome synchronization issue you need to induce WebDriverWait() and wait for frameToBeAvailableAndSwitchToIt() and following locator.

To get the link details induce WebDriverWait() and wait for visibilityOfAllElementsLocatedBy() and following locator.

WebDriver driver = new ChromeDriver();
String baseUrl = "https://js.devexpress.com/Demos/WidgetsGallery/Demo/DataGrid/PopupEditing/Angular/Light/";
driver.get(baseUrl);
driver.manage().window().maximize();        
new WebDiverWait(driver, 20).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.id("demoFrame")));
List<WebElement> we =new WebDriverWait(driver, 10).until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.linkText("Edit")));
System.out.println(we.size());
we.get(1).click();
