選択要素の操作

The Select object will now give you a series of commands that allow you to interact with a <select> element.

If you are using Java or .NET make sure that you’ve properly required the support package in your code. See the full code from GitHub in any of the examples below.

Note that this class only works for HTML elements select and option. It is possible to design drop-downs with JavaScript overlays using div or li, and this class will not work for those.

Types

Select methods may behave differently depending on which type of <select> element is being worked with.

Single select

This is the standard drop-down object where one and only one option may be selected.

<select name="selectomatic">
    <option selected="selected" id="non_multi_option" value="one">One</option>
    <option value="two">Two</option>
    <option value="four">Four</option>
    <option value="still learning how to count, apparently">Still learning how to count, apparently</option>
</select>

Multiple select

This select list allows selecting and deselecting more than one option at a time. This only applies to <select> elements with the multiple attribute.

<select name="multi" id="multi" multiple="multiple">
    <option selected="selected" value="eggs">Eggs</option>
    <option value="ham">Ham</option>
    <option selected="selected" value="sausages">Sausages</option>
    <option value="onion gravy">Onion gravy</option>
</select>

Create class

First locate a <select> element, then use it to initialize a Select object. Note that as of Selenium 4.5, you can’t create a Select object if the <select> element is disabled.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        WebElement selectElement = driver.findElement(By.name("selectomatic"));
        Select select = new Select(selectElement);

    select_element = driver.find_element(By.NAME, 'selectomatic')
    select = Select(select_element)

            var selectElement = driver.FindElement(By.Name("selectomatic"));
            var select = new SelectElement(selectElement);

    select_element = driver.find_element(name: 'selectomatic')
    select = Selenium::WebDriver::Support::Select.new(select_element)

      const selectElement = await driver.findElement(By.name('selectomatic'))
      const select = new Select(selectElement)

    val selectElement = driver.findElement(By.name("selectomatic"))
    val select = Select(selectElement)

List options

There are two lists that can be obtained:

All options

Get a list of all options in the <select> element:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        List<WebElement> optionList = select.getOptions();

    option_list = select.options

            IList<IWebElement> optionList = select.Options;

    option_list = select.options

      const optionList = await select.getOptions()

    val optionList = select.getOptions()

Selected options

Get a list of selected options in the <select> element. For a standard select list this will only be a list with one element, for a multiple select list it can contain zero or many elements.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        List<WebElement> selectedOptionList = select.getAllSelectedOptions();

    selected_option_list = select.all_selected_options

            IList<IWebElement> selectedOptionList = select.AllSelectedOptions;

    selected_option_list = select.selected_options

      const selectedOptionList = await select.getAllSelectedOptions()

    val selectedOptionList = select.getAllSelectedOptions()

Select option

The Select class provides three ways to select an option. Note that for multiple select type Select lists, you can repeat these methods for each element you want to select.

Text

Select the option based on its visible text

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        select.selectByVisibleText("Four");

    select.select_by_visible_text('Four')

            select.SelectByText("Four");

    select.select_by(:text,'Four')

      await select.selectByVisibleText('Four')

    select.selectByVisibleText("Four")

Value

Select the option based on its value attribute

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        select.selectByValue("two");

    select.select_by_value('two')

            select.SelectByValue("two");

    select.select_by(:value,'two')

      await select.selectByValue('two')

    select.selectByValue("two")

Index

Select the option based on its position in the list

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        select.selectByIndex(3);

    select.select_by_index(3)

            select.SelectByIndex(3);

    select.select_by(:index,3)

      await select.selectByIndex(3)

    select.selectByIndex(3)

Disabled options

Selenium v4.5

Options with a disabled attribute may not be selected.

    <select name="single_disabled">
      <option id="sinlge_disabled_1" value="enabled">Enabled</option>
      <option id="sinlge_disabled_2" value="disabled" disabled="disabled">Disabled</option>
    </select>

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        Assertions.assertThrows(UnsupportedOperationException.class, () -> {
            select.selectByValue("disabled");
        });

    with pytest.raises(NotImplementedError):
        select.select_by_value('disabled')

            Assert.ThrowsException<InvalidOperationException>(() => select.SelectByValue("disabled"));

    expect {
      select.select_by(:value, 'disabled')
    }.to raise_exception(Selenium::WebDriver::Error::UnsupportedOperationError)

      await assert.rejects(async () => {
        await select.selectByValue("disabled")
      }, {
        name: 'UnsupportedOperationError',

    Assertions.assertThrows(UnsupportedOperationException::class.java) {
      select.selectByValue("disabled")
    }

De-select option

Only multiple select type select lists can have options de-selected. You can repeat these methods for each element you want to select.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        select.deselectByValue("eggs");

    select.deselect_by_value('eggs')

            select.DeselectByValue("eggs");

    select.deselect_by(:value, 'eggs')

      await select.deselectByValue('eggs')

    select.deselectByValue("eggs")
