Guide: Choosing an Option from a Dropdown Menu Using Selenium

Check out this piece of code :

 <select name="backgroundcolor" onchange="backgroundColor();">
    <option value="200">Red</option>
    ....      
 </select>

I attempted the following code to choose the "Red" option but it didn't work.

Select dropDown = new Select(driver.findElement(By.name("backgroundcolor")));
dropDown.selectByValue("200");

I encountered a NoSuchElementException Exception

Unable to locate element //*[name='backgroundcolor']

Answer №1

give this a shot

Try using the following code snippet:
Select dropdown = new Select(driver.findElement(By.id("dropdown")));
dropdown.deselectAll();
dropdown.selectByValue("option1");

You might want to consider changing the locator method from By.name to something like:

By.xpath("//xpath_to_dropdown"))

Answer №2

Give this a shot, make sure to translate the following code into the programming language you prefer

import webdriver.support.select.Select as WebDriverSelect
element = WebDriverSelect(driver.findElementByName('bgcolor'))
element.chooseByValue('200')

Answer №3

Upon observation, it appears that the issue may be related to timing. In such cases, it is recommended to patiently wait until the desired element is visible on the webpage. Consider implementing the following approach:

By selector = By.name("backgroundcolor");
WebDriverWait waiting = new WebDriverWait(driver, 30);
waiting.until(ExpectedConditions.presenceOfElementLocated(selector));
Select dropdownMenu = new Select(driver.findElement(selector));
dropdownMenu.selectByValue("200");

Answer №4

Encountered an error stating "Unable to locate element *[name='backgroundcolor']." Fortunately, I managed to resolve this issue by first accessing the iframe that contains the dropdown menu. It appears to have been a timing problem.

wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(theindexofframe));
wait.until(ExpectedConditions.visibilityOfElementLocated(By.name("backgroundcolor")));

It is important to wait for the iframe to load before waiting for the "backgroundcolor" element to appear. Once both are loaded, you can proceed to select a value from the dropdown as shown below:

Select dropDown = new Select(driver.findElement(By.name("backgroundcolor")));
dropDown.selectByValue("200");
