单击列表中找到的所有元素<WebElement>

Question

I am trying to click all of the instances of an element found by the class attribute found in an i tag within an anchor tag in the row of a dynamic table. Specifically, its a row with several cells and in the last cell there is a series of 4 links with either and X or an O. If the square is an X, it can be clicked and after a short wait, changes to an O. The links are written as follows:

<a class="foobar"><i class="dontNeedToClick"><i></a>
<a class="foobar"><i class="dontNeedToClick"><i></a>
<a class="foobar"><i class="needToClick"><i></a>
<a class="foobar"><i class="dontNeedToClick"><i></a>

When the needToClick element is clicked, the class would change to a dontNeedToClick element There are less than a hundred X's in a database of thousands of O's to scroll through, so something to automate clicking them would save a lot of time. I can successfully count the instances the element appears in the table, but when I put the elements into a List object using .findElements() and attempt to iterate through it, I get ElementNotVisibleException.

Here is my sample code so far:

// get the count of thumbs down accounts
    int elementsCount= driver.findElements(By.className("needToClick")).size();
    System.out.println("Amount of elements: " + elementsCount);

// loop and click through all elements found

    for (int x = 0; x < elementCount; x++) {
        List<WebElement> elements = driver.findElements(By.className("needToClick"));
        WebElement client = elements.get(x);
        client.click();
        Thread.sleep(5000);
    }

I have tried using Iterator and get the same exception thrown at me.

        Iterator<WebElement> clickElement = elements.iterator();
        while (clickElement.hasNext()) {
            clickElement.next().click();
        }

I have also tried using a foreach loop.

    List<WebElement> thumbsDown = driver.findElements(By.className(expectedClass));

    for(WebElement element : thumbsDown) {
        element.click();
    }

I would use xpath but I am not very experienced with dynamic tables and haven't been able to find an approach that would fetch the row containing the element I'm looking for and other elements relative to it and figured a less than elegant approach such as just finding all the elements by the class name would suffice. Would appreciate any help.

Answer 1

Make sure elements you try to click is visible. If you don't care about visibility click with javascipt:

JavascriptExecutor js = (JavascriptExecutor) driver;
WebDriverWait wait = new WebDriverWait(driver, 5);

List<WebElement> elements = driver.findElements(By.className("needToClick"));
elements.forEach(e -> {
    js.executeScript("arguments[0].click();", e);
    wait.until(ExpectedConditions.attributeToBe(e,"class", "dontNeedToClick"));
    //if element have not only dontNeedToClick class use attributeContains
    //wait.until(ExpectedConditions.attributeContains(e,"class", "dontNeedToClick"));
});

Check if you can click one element and class changes:

driver.findElement(By.className("needToClick")).click();

if not try xpath:

driver.findElement(By.xpath("//a[i[@class='needToClick']]"));
//or
driver.findElement(By.xpath("//a[i[contains(@class,'needToClick')]]"));

Answer 2

Is the exception being thrown when you iterate through the list, or when you attempt to generate the list?

If it's the former, what you need to do is re-generate the list after every click - even if you load a new page that's exactly the same, selenium will see the elements on the new page as 'different' and you won't be able to use any of the elements you found on the old page. (Edit: I looked through your loop again, and it seems like you're doing this part right. My guess would be you need to wait for the page to load fully)

If it's the latter, then you might need to wait for the page to load, and make sure that the elements you're trying to find all exist. In selenium you can set explicit or implicit timeouts, but I personally prefer time.sleep(however many seconds) since selenium might 'say' it's loaded before fully loading all the javascript.

Hope this helps!

Answer 3

I think you have to use xpath, as I saw your element in <i> tags

like this

//a[@class='foobar']//i[contains(@class,'Click')]

Code

 List<WebElement> elements = driver.findElements(By.xpath("//a[@class='foobar']//i[contains(@class,'Click')]"));
 for (WebElement tempEle : elements) {
  tempEle.click();
}

You can also use if with break in the For each loop to seelct particular element

Answer 4

If you want to select every Element of a List List just use a foreach-loop:

for(WebElement e : List<WebElement>){
   e.doThings();
}

Answer 5

   int elementsCount= driver.findElements(By.className("needToClick")).size();
System.out.println("Amount of elements: " + elementsCount);

    List<WebElement> elements = driver.findElements(By.className("needToClick"));

for (int x = 0; x < elementCount; x++) {
    WebElement client = elements.get(x);
    Thread.sleep(5000);

client.click(); }

Answer 6

List elements = driver.findElements(By.className("needToClick")); elements.get(0).click(); It will work for the click event on web list Elements
