当您选择 Insurance Test Client 时，只有您可以选择 Product Insurance，这实质上意味着HTML DOM 发生更改，导致 StaleElementException.为了避免这种情况，一旦我们从第一个下拉列表中选择，我们需要为第二个下拉列表的元素在 HTML DOM 中呈现一些wait.然后我们将使用 Select 类来选择一个选项.试试下面的代码块:
When you select Insurance Test Client then only you get the option Product Insurance, which essentially means the HTML DOM gets changed, which results in StaleElementException. To avoid that, once we select from the first dropdown, we need to induce some wait for the elements of the second dropdown to render in the HTML DOM. Then we will use Select Class to select an option. Try out the following code block:
//Select Channel
Select oSelectChannel = new Select(driver.findElement(By.id("client")));
oSelectChannel.selectByVisibleText("Insurance Test Client");
WebDriverWait wait5 = new WebDriverWait(driver, 10);
wait5.until(ExpectedConditions.elementToBeClickable(By.xpath("xpath_of_a_Category_item")));
//Select Category
Select oSelectCategory = new Select(driver.findElement(By.xpath("//*[@id='category']")));
oSelectCategory.selectByVisibleText("Product Insurance");
