python selenium如何单击选项

我想点击这些坏男孩中的一个选项： 如何使代码单击它并使用

value=“196277”

选择选项

您可以使用xpath查找特定的选项元素：

your_choice=browser.find_element_by_xpath("//select/option[@value='196277']")

然后对其调用

click（）

函数：

your_choice.click()

---

这可能对您有用：

from selenium.webdriver.support.ui import Select
from selenium import webdriver as driver
menu = Select(driver.find_element_by_id('matrix-element-666'))
for option in menu:
    if option.value == '196277':
        option.select
    else:
        pass

显然，我在stackoverflow或文档中找到的方法都不起作用（仅在FireFox webdriver中^^°）。所以我做了一个变通方法，在选项的值和文本之间进行转换。选项文本将作为键发送，以在浏览器中选择正确的选项，lol

我不知道，有时候selenium就像地狱，所以如果你正在寻找一个好的抓取（而不是webtesting）框架，我推荐scrapy.org

当我尝试这样做时，我得到了一个错误消息：xpath一定是不正确的，因为我猜select标记周围也有其他html元素。此页-，将帮助您在页面上找到option元素的特定xpath。之后，点击功能将根据需要工作。我使用chrome。。Firefox实际上不起作用，我只需要睡一觉（2），因为它不起作用的原因是它在加载之前就搜索//select/选项[@value='196277']。这就是为什么它给了我找不到的错误。它没有先装芬兰货！在搜索之前。不知何故，这在FirefoxWebDriver上不起作用，但这不是问题所在^^第2行-驱动程序未定义SeleniumDoesn也将是您的webdriver，我得到的错误是：selenium.common.exceptions.NoSuchElementException:消息：没有这样的元素：无法定位元素：{“方法”：“类名”，“选择器”：“字段媒体”}提供了更多详细信息。如果我们不知道你的密码，我们就帮不了你。该站点可能有一个或多个iframe。这必须首先处理，这不是问题的一部分。你想要完整的html是什么？self等于什么？self是python的东西，请看这里。self.driver是webdriverWelcome堆栈溢出！请阅读。请提供您尝试过的代码和执行结果，包括任何错误消息等。
