用Selenium处理下拉菜单

Question

我想自动地在 谷歌表格 下拉列表，如下图所示。

就像下面这个结构一样

<div jscontroller="liFoG" jsaction="rcuQ6b:vZc4S;O22p3e:zjh6rb;b2trFe:eVidQc;JIbuQc:d3sQLd;" class="freebirdFormviewerComponentsQuestionSelectRoot"><div role="listbox" aria-expanded="true" class="quantumWizMenuPaperselectEl appsMaterialWizMenuPaperselectSelect freebirdFormviewerComponentsQuestionSelectSelect freebirdThemedSelectDarkerDisabled noMaxWidth isOpen" jscontroller="YwHGTd" jsaction="click:cOuCgd(LgbsSe);

我需要先点击列表，然后再点击某个选项。

我试图用这段代码来处理它。

                 lists = container.find_element_by_class_name("quantumWizMenuPaperselectOption.appsMaterialWizMenuPaperselectOption.freebirdThemedSelectOptionDarkerDisabled.exportOption.isSelected.isPlaceholder")
                 if lists !=[]:
                     for list in lists:
                         option = container.find_element_by_class_name("quantumWizMenuPaperselectOption.appsMaterialWizMenuPaperselectOption.freebirdThemedSelectOptionDarkerDisabled.exportOption.isSelected")
                         if option:
                             option.click()

但我有一个问题... ...

Answer 1

使用下面的代码。

driver.find_element_by_class_name('quantumWizMenuPaperselectOptionList').click()
options = driver.find_elements_by_css_selector('.exportSelectPopup div.quantumWizMenuPaperselectOption')
random_index = randint(1, len(options))
options[random_index].click()

解释。

1. 找到下拉元素并执行点击
2. 识别所有的下拉值元素并存储到一个列表中
3. 在列表的起始索引和最大大小之间生成一个随机数（假设列表大小为4，起始索引为1，那么它将在1和4之间生成一个随机数）。
4. 点击选项列表中的随机数指数，将随机选择一个下拉值。
