问题:如何使用Python使用Selenium选择下拉菜单值?

我需要从中选择一个元素 下拉菜单中。

例如:

<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)首先,我必须单击它。我这样做:

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

2)之后,我必须选择一个好的元素,让我们说Mango

我尝试这样做,inputElementFruits.send_keys(...)但是没有用。

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.

除非您的点击触发了某种Ajax调用来填充列表,否则您实际上不需要执行该点击。

只需找到元素,然后枚举选项,然后选择所需的选项即可。

这是一个例子:

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

您可以在以下网址中阅读更多内容:https :

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提供了一个方便的来使用select -> option构造:

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')

也可以看看:

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')

首先,您需要导入Select类,然后创建Select类的实例。创建Select类的实例后,您可以对该实例执行select方法以从下拉列表中选择选项。这是代码

from selenium.webdriver.support.select import Select

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

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)

回答 3

希望这段代码对您有所帮助。

from selenium.webdriver.support.ui import Select

ID为下拉列表的元素

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

带xpath的下拉元素

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

带CSS选择器的下拉元素

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

从下拉列表中选择“香蕉”

  1. 使用下拉索引

ddelement.select_by_index(1)

  1. 使用下拉菜单的值

ddelement.select_by_value('1')

  1. 您可以使用匹配显示在下拉菜单中的文本。

ddelement.select_by_visible_text('Banana')

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)

  1. Using the value of dropdown

ddelement.select_by_value('1')

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

ddelement.select_by_visible_text('Banana')

我尝试了很多事情,但下拉菜单位于表内,因此我无法执行简单的选择操作。仅以下解决方案有效。在这里,我突出显示下拉元素并按下箭头,直到获得所需的值-

        #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)

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)

您无需单击任何内容。使用xpath或任何您选择的方式查找,然后使用发送键

例如: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")

而已。

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.

您可以很好地使用CSS选择器组合

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

将attribute = value css选择器中的1更改为与所需水果对应的值。

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)

会很好的工作

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

它与选项值一起使用:

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

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()

回答 9

这样,您可以在任何下拉菜单中选择所有选项。

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)

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)

使用selenium.webdriver.support.ui.Select类与下拉选择配合使用的最佳方法,但由于HTML的设计问题或其他问题,有时它无法按预期工作。

在这种情况下,您也可以使用execute_script()以下替代方法:

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);

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);

按照提供的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>

选择一个 <option>元素中元素菜单,您必须使用Select Class。此外,由于您必须与你有诱导WebDriverWaitelement_to_be_clickable()

选择<option>文本作为芒果您可以使用以下两种定位策略之一

  • 使用ID属性和select_by_visible_text()方法:

    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")
  • 使用CSS-SELECTORselect_by_value()方法:

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

    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)

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 menu you have to use the Select Class. Moreover, as you have to interact with the you have to induce WebDriverWait for the element_to_be_clickable().

To select the <option> with text as Mango from the 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)
