如何使用Python使用Selenium选择下拉菜单值？

I need to select an element from a drop-down menu.

For example:

<select id="fruits01" class="select" name="fruits">
  <option value="0">Choose your fruits:</option>
  <option value="1">Banana</option>
  <option value="2">Mango</option>
</select>

1) First I have to click on it. I do this:

inputElementFruits = driver.find_element_by_xpath("//select[id='fruits']").click()

2) After that I have to select the good element, lets say Mango.

I tried to do it with inputElementFruits.send_keys(...) but it did not work.

Unless your click is firing some kind of ajax call to populate your list, you don’t actually need to execute the click.

Just find the element and then enumerate the options, selecting the option(s) you want.

Here is an example:

from selenium import webdriver
b = webdriver.Firefox()
b.find_element_by_xpath("//select[@name='element_name']/option[text()='option_text']").click()

Selenium provides a convenient to work with select -> option constructs:

from selenium import webdriver
from selenium.webdriver.support.ui import Select

driver = webdriver.Firefox()
driver.get('url')

select = Select(driver.find_element_by_id('fruits01'))

# select by visible text
select.select_by_visible_text('Banana')

# select by value 
select.select_by_value('1')

• What is the correct way to select an using Selenium’s Python WebDriver?

firstly you need to import the Select class and then you need to create the instance of Select class. After creating the instance of Select class, you can perform select methods on that instance to select the options from dropdown list. Here is the code

from selenium.webdriver.support.select import Select

select_fr = Select(driver.find_element_by_id("fruits01"))
select_fr.select_by_index(0)

I hope this code will help you.

from selenium.webdriver.support.ui import Select

dropdown element with id

ddelement= Select(driver.find_element_by_id('id_of_element'))

dropdown element with xpath

ddelement= Select(driver.find_element_by_xpath('xpath_of_element'))

dropdown element with css selector

ddelement= Select(driver.find_element_by_css_selector('css_selector_of_element'))

Selecting ‘Banana’ from a dropdown

1. Using the index of dropdown

ddelement.select_by_index(1)

2. Using the value of dropdown

ddelement.select_by_value('1')

3. You can use match the text which is displayed in the drop down.

ddelement.select_by_visible_text('Banana')

I tried a lot many things, but my drop down was inside a table and I was not able to perform a simple select operation. Only the below solution worked. Here I am highlighting drop down elem and pressing down arrow until getting the desired value –

        #identify the drop down element
        elem = browser.find_element_by_name(objectVal)
        for option in elem.find_elements_by_tag_name('option'):
            if option.text == value:
                break

            else:
                ARROW_DOWN = u'\ue015'
                elem.send_keys(ARROW_DOWN)

You don’t have to click anything. Use find by xpath or whatever you choose and then use send keys

For your example: HTML:

<select id="fruits01" class="select" name="fruits">
    <option value="0">Choose your fruits:</option>
    <option value="1">Banana</option>
    <option value="2">Mango</option>
</select>

Python:

fruit_field = browser.find_element_by_xpath("//input[@name='fruits']")
fruit_field.send_keys("Mango")

That’s it.

You can use a css selector combination a well

driver.find_element_by_css_selector("#fruits01 [value='1']").click()

Change the 1 in the attribute = value css selector to the value corresponding with the desired fruit.

from selenium.webdriver.support.ui import Select
driver = webdriver.Ie(".\\IEDriverServer.exe")
driver.get("https://test.com")
select = Select(driver.find_element_by_xpath("""//input[@name='n_name']"""))
select.select_by_index(2)

It will work fine

It works with option value:

from selenium import webdriver
b = webdriver.Firefox()
b.find_element_by_xpath("//select[@class='class_name']/option[@value='option_value']").click()

In this way you can select all the options in any dropdowns.

driver.get("https://www.spectrapremium.com/en/aftermarket/north-america")

print( "The title is  : " + driver.title)

inputs = Select(driver.find_element_by_css_selector('#year'))

input1 = len(inputs.options)

for items in range(input1):

    inputs.select_by_index(items)
    time.sleep(1)

The best way to use selenium.webdriver.support.ui.Select class to work to with dropdown selection but some time it does not work as expected due to designing issue or other issues of the HTML.

In this type of situation you can also prefer as alternate solution using execute_script() as below :-

option_visible_text = "Banana"
select = driver.find_element_by_id("fruits01")

#now use this to select option from dropdown by visible text 
driver.execute_script("var select = arguments[0]; for(var i = 0; i < select.options.length; i++){ if(select.options[i].text == arguments[1]){ select.options[i].selected = true; } }", select, option_visible_text);

As per the HTML provided:

<select id="fruits01" class="select" name="fruits">
  <option value="0">Choose your fruits:</option>
  <option value="1">Banana</option>
  <option value="2">Mango</option>
</select>

To select an <option> element from a html-select menu you have to use the Select Class. Moreover, as you have to interact with the drop-down-menu you have to induce WebDriverWait for the element_to_be_clickable().

To select the <option> with text as Mango from the dropdown you can use you can use either of the following Locator Strategies:

• Using ID attribute and select_by_visible_text() method:

  from selenium import webdriver
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
  from selenium.webdriver.support.ui import Select
  
  select = Select(WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "fruits01"))))
  select.select_by_visible_text("Mango")
  

• Using CSS-SELECTOR and select_by_value() method:

  select = Select(WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "select.select[name='fruits']"))))
  select.select_by_value("2")
  

• Using XPATH and select_by_index() method:

  select = Select(WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "//select[@class='select' and @name='fruits']"))))
  select.select_by_index(2)
  

1. List item

public class ListBoxMultiple {

public static void main(String[] args) throws InterruptedException {
    // TODO Auto-generated method stub
    System.setProperty("webdriver.chrome.driver", "./drivers/chromedriver.exe");
    WebDriver driver=new ChromeDriver();
    driver.get("file:///C:/Users/Amitabh/Desktop/hotel2.html");//open the website
    driver.manage().window().maximize();


    WebElement hotel = driver.findElement(By.id("maarya"));//get the element

    Select sel=new Select(hotel);//for handling list box
    //isMultiple
    if(sel.isMultiple()){
        System.out.println("it is multi select list");
    }
    else{
        System.out.println("it is single select list");
    }
    //select option
    sel.selectByIndex(1);// you can select by index values
    sel.selectByValue("p");//you can select by value
    sel.selectByVisibleText("Fish");// you can also select by visible text of the options
    //deselect option but this is possible only in case of multiple lists
    Thread.sleep(1000);
    sel.deselectByIndex(1);
    sel.deselectAll();

    //getOptions
    List<WebElement> options = sel.getOptions();

    int count=options.size();
    System.out.println("Total options: "+count);

    for(WebElement opt:options){ // getting text of every elements
        String text=opt.getText();
        System.out.println(text);
        }

    //select all options
    for(int i=0;i<count;i++){
        sel.selectByIndex(i);
        Thread.sleep(1000);
    }

    driver.quit();

}
