Selenium: How to wait for options in a select to be populated?

Question

I am using Selenium for the first time and am overwhelmed by the options. I am using the IDE in Firefox.

When my page loads, it subsequently fetches values via an JS

Answer 1

Using java 8 Awaitility

Awaitility.await()
.atMost(5, TimeUnit.SECONDS)
.until(() -> select.getOptions().size() > 0);

Answer 2

Its work for me:

  WebElement element = driver.findElement(By.xpath("//select[@name='NamE']/option[1]"));
  return element.getAttribute("text");

Answer 3

Try the below code

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException

try:
    # 10 is the maximum time to wait
    element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.CSS_SELECTOR, "#mySelectId option[value='valueofOptionYouExpectToBeLoaded']"))
    )
except TimeoutException:
    print("Time out")

#  Write your code

Answer 4

We had similar problem where the options within drop down was fetched from a third party service, which sometimes was a slower operation.

Select select = new Select(driver.findElement(cssSelector("cssSelectorOfSelectBox")));    
waitUnitlSelectOptionsPopulated(select)

here is the definition for waitUnitlSelectOptionsPopulated

private void waitUntilSelectOptionsPopulated(final Select select) {
            new FluentWait<WebDriver>(driver)
                    .withTimeout(60, TimeUnit.SECONDS)
                    .pollingEvery(10, TimeUnit.MILLISECONDS)
                    .until(new Predicate<WebDriver>() {
                        public boolean apply(WebDriver d) {
                            return (select.getOptions().size() > 1);
                        }
                    });
        }

Note: A check of select.getOptions().size() >1 was needed in our case as we had one static option always displayed.

Answer 5

I used waitForElementPresent with a css target.

Example: To wait for

<select id="myselect"></select>

to be populated with

<option value="123">One-two-three</option>

use

• Command: waitForElementPresent
• Target: css=#myselect option[value=123]
• Value: (leave it empty)

Answer 6

I think you should be use

waitForElementPresent command. If possible let's me see your selenium IDE code.
