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.
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)
it('Select an option', async function () {
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:
List<WebElement> optionList = select.getOptions(); option_list = select.options IList<IWebElement> optionList = select.Options; option_list = select.options 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.
List<WebElement> selectedOptionList = select.getAllSelectedOptions(); selected_option_list = select.all_selected_options IList<IWebElement> selectedOptionList = select.AllSelectedOptions; selected_option_list = select.selected_options 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
select.selectByVisibleText("Four"); select.select_by_visible_text('Four') select.SelectByText("Four"); select.select_by(:text, 'Four') const countElement = await driver.findElement(By.css("option[value='still learning how to count, apparently']"))
select.selectByVisibleText("Four")Value
Select the option based on its value attribute
select.selectByValue("two"); select.select_by_value('two') select.SelectByValue("two"); select.select_by(:value, 'two') assert.equal(true, await fourElement.isSelected())
select.selectByValue("two")Index
Select the option based on its position in the list
select.selectByIndex(3); select.select_by_index(3) select.SelectByIndex(3); select.select_by(:index, 3) assert.equal(true, await twoElement.isSelected())
select.selectByIndex(3)Disabled options
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>
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) const select = await new Select(selectElement)
await assert.rejects(async () => {
await select.selectByValue("disabled")
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.
select.deselectByValue("eggs"); select.deselect_by_value('eggs') select.DeselectByValue("eggs"); select.deselect_by(:value, 'eggs') assert.equal(true, await gravyElement.isSelected())
select.deselectByValue("eggs")
