Selenium Python 中的 Select 下拉菜单

Question

I can't select values in a list. I tried using find_element_by_class_name() to open the menu but when I need to select a <li> returns that element doesn't have a function click() .

Here the code:

click_menu = driver.find_element_by_class_name("periodSelector")
click_menu[1].click()

Here is the HTML that I am trying to parse:

<div data-period-selector="" data-period="periodFilter">
    <div class="periodSelectorContainer">
        <div class="btn-group periodSelector">
            <button class="flat-btn dropdown-toggle periodToggle ng-binding" data-toggle="dropdown"> 20/02/2021 - 22/03/2021 <span class="dropdown-arrow"></span> </button>
            <ul class="dropdown-menu">
                <li>
                    <a href="javascript:void(0);" class="new-financ" ng-click="selectToday()"><i></i>
                        <span class="pull-left">Hoje</span>
                        <span class="pull-right"></span>
                    </a>
                </li>
                <li>
                    <a href="javascript:void(0);" class="new-financ" ng-click="selectThisWeek()"><i>
                </li>

Answer 1

There are multiple class names you have to use a css selector.

click_menu = driver.find_element_by_css_selector("button.flat-btn.dropdown-toggle.periodToggle.ng-binding")
click_menu.click()

Clicks 1st li tag.

driver.find_element_by_xpath("ul[@class='dropdown-menu']/li[1]").click()

Answer 2

periodSelector is a class on a DIV

<div class="btn-group periodSelector">

I'm assuming that you need to click on the BUTTON

<button class="flat-btn dropdown-toggle periodToggle ng-binding" data-toggle="dropdown">

Most of those classes seem generic (probably not unique) but I'm guessing that periodToggle might be unique given the date range. Try

driver.find_element_by_css_selector("button.periodToggle").click()

NOTE: You have an error in your code. You are using .find_element_by_class_name() (singular) but have array notation on the next line, click_menu[1] . In this case, you can just use click_menu.click() . You'd only need the array notation if you were using .find_elements_by_*() (note the plural, elements).
