Handling dynamic web elements

Handling dynamic web elements

Dynamic web elements change based on user interactions or application state. It's important to handle them effectively in Selenium automation. If Selenium WebDriver expects a web element but doesn't find it, it'll throw an exception, and the script would fail.

Examples

// Example 1: Handling dynamic dropdown
WebElement dropdown = driver.findElement(By.id("dynamicDropdown"));
Select select = new Select(dropdown);
select.selectByVisibleText("Option 1");

// Example 2: Handling dynamic table
WebElement table = driver.findElement(By.xpath("//table[@id='dynamicTable']"));
List<WebElement> rows = table.findElements(By.tagName("tr"));
for (WebElement row : rows) {
    List<WebElement> cells = row.findElements(By.tagName("td"));
    for (WebElement cell : cells) {
        System.out.println(cell.getText());
    }
}

// Example 3: Using explicit wait
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("dynamicElement")));
WebElement dynamicElement = driver.findElement(By.id("dynamicElement"));
dynamicElement.click();
