Selenium can't find iframe after postback inside the iframe after finding one element inside the frame

Question

I am trying to create a test where I have to fill out some information inside an iframe. Getting access to the iframe work fine and I can fill out information inside the frame. The issue is that when I find out a element 'A' it has a postback attached to it which reloads the content inside the iframe, to find out another element 'B'. So i am not able to find that element.I am getting below error:

org.openqa.selenium.WebDriverException: unknown error: Element <iframe style="overflow-x:hidden;" id="t5" height="1350" frameborder="0" width="98%" src="https://edata.ndtv.com/coronavirus/table/india_table.html?shgraph=1&amp;days=7" cd_frame_id_="7da8f2aea5a580b3a6e90a9d5016fa0d">...</iframe> is not clickable at point (554, 7). Other element would receive the click: <div class="topnav2014" style="border-bottom: none;">...</div>
  (Session info: chrome=85.0.4183.83)

Here are my observations: When I first locate the iframe it looks like this:

<iframe style="overflow-x:hidden;" id="t5" height="1350" frameborder="0" width="98%" src="https://edata.ndtv.com/coronavirus/table/india_table.html?shgraph=1&amp;days=7">

After the postback has occurred it looks like this:

<iframe style="overflow-x:hidden;" id="t5" height="1350" frameborder="0" width="98%" src="https://edata.ndtv.com/coronavirus/table/india_table.html?shgraph=1&amp;days=7" cd_frame_id_="a5006acf28d8c288313681ab9ad7a4fa">

I can easily find element A:

But element B i am not able to find The code fails when I try to get hold of the iframe element.

How can I get hold of the iframe again, after the postback inside the frame?

I have tried this suggestion also but it is not working

//Ensure that you are back to the base frame  
driver.SwitchTo().DefaultContent();
//SwitchTo the intended frame
 driver.SwitchTo().Frame(driver.FindElement(By.XPath("//iframe[contains(@src,'<removed for clearity>')]")));

Answer 1

Use a driver.executescript() for the first problem since another element is receiving the click.

element = driver.findElement(By.id(""));
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].click();", element);

This error message...

org.openqa.selenium.WebDriverException: unknown error: Element <iframe style="overflow-x:hidden;" id="t5" height="1350" frameborder="0" width="98%" src="https://edata.ndtv.com/coronavirus/table/india_table.html?shgraph=1&amp;days=7" cd_frame_id_="7da8f2aea5a580b3a6e90a9d5016fa0d">...</iframe> is not clickable at point (554, 7). Other element would receive the click: <div class="topnav2014" style="border-bottom: none;">...</div>

...implies that the WebDriverException was raised as you tried to invoke click() on the <iframe> element.

Factually, instead of clicking on the <iframe> element you would invoke click() on an element within the <iframe>. Moreover, as the the desired element is within a <iframe> so you have to:

• Induce WebDriverWait for the desired frameToBeAvailableAndSwitchToIt.
• Induce WebDriverWait for the desired elementToBeClickable.
• You can use either of the following Locator Strategies:

  • Using xpath:

    new WebDriverWait(driver, 10).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.xpath("//iframe_xpath")));
    new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.xpath("element_xpath"))).click();

Answer 3

I am able to extract the data of the active cases rise and fall for every state. There is a single frame which contains both the locators shared by you. Check below working code.

    driver.get("https://www.ndtv.com/coronavirus");
    driver.manage().window().maximize();
    WebDriverWait wait = new WebDriverWait(driver, 20);
    wait.until(ExpectedConditions.elementToBeClickable(By.className("tab-wrapper")));
    driver.switchTo().frame(driver.findElement(By.xpath("//iframe[contains(@src,'https://edata.ndtv.com/coronavirus/table/india_table.html?shgraph=1')]")));
    
    //cases down
    List<WebElement> eleCasesUp = driver.findElements(By.xpath("//tr//td[3]//p//span[@class='data-up']"));
    List<String> casesUpList = new ArrayList<String>();
    for (WebElement element : eleCasesUp) { 
        casesUpList.add(element.getText()); 
    }
    
    //cases up
    List<WebElement> eleCasesDown = driver.findElements(By.xpath("//tr//td[3]//p//span[@class='data-down']"));
    List<String> casesDownList = new ArrayList<String>();
    for (WebElement element : eleCasesDown) { 
        casesDownList.add(element.getText()); 
    }
    
    System.out.println("Cases Up List -->" + casesUpList);
    System.out.println("Cases Down List -->" + casesDownList);
