首先你需要导入Select类，然后你需要创建Select类的实例。 创建Select类的实例后，可以在该实例上执行选择方法，从下拉列表中选择选项。 下面是代码

from selenium.webdriver.support.select import Select

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

根据提供的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>

要从html-select菜单中选择<option>元素，必须使用select类。此外，当你必须与下拉菜单交互时，你必须为element_to_be_clickable()诱导WebDriverWait。

要从下拉菜单中选择<选项>，文本为Mango，你可以使用以下定位器策略之一:

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)

我尝试了很多东西，但是我的下拉是在一个表中，我不能执行简单的选择操作。只有下面的解决方案有效。在这里，我突出显示下拉elem和按下箭头，直到得到所需的值-

        #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)

列表项

公共类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();

}

}

你可以很好地使用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更改为所需水果对应的值。

使用selenium.webdriver.support.ui.的最佳方式是使用下拉选择选择要工作的类，但有时由于设计问题或HTML的其他问题，它不能像预期的那样工作。

在这种情况下，您也可以使用execute_script()作为替代解决方案，如下所示

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);
