Using Selenium in Python to click/select a radio button
提问by Das Bruno
I am trying to select from a list of 3 buttons, but can't find a way to select them. Below is the HTML I am working with.
我试图从 3 个按钮的列表中进行选择，但找不到选择它们的方法。下面是我正在使用的 HTML。
<input name="pollQuestion" type="radio" value="SRF">
<font face="arial,sans-serif" size="-1">ChoiceOne</font><br />
<input name="pollQuestion" type="radio" value="COM">
<font face="arial,sans-serif" size="-1">ChoiceTwo</font><br />
<input name="pollQuestion" type="radio" value="MOT">
<font face="arial,sans-serif" size="-1">ChoiceThree</font>
I can find it by using the following code:
我可以使用以下代码找到它：
for i in browser.find_elements_by_xpath("//*[@type='radio']"):
print i.get_attribute("value")
This outputs: SRF,COM,MOT
这输出：SRF，COM，MOT
But I would like to select ChoiceOne. (To click it) How do I do this?
但我想选择ChoiceOne。（单击它）我该怎么做？

Use CSS Selector or XPath to select by valueattribute directly, then click it.
使用 CSS Selector 或 XPathvalue直接按属性选择，然后单击它。
browser.find_element_by_css_selector("input[type='radio'][value='SRF']").click()
# browser.find_element_by_xpath(".//input[@type='radio' and @value='SRF']").click()
Corrections (but OP should learn how to look up in documentation)
更正（但 OP 应该学习如何在文档中查找）
- In Python binding,
find_elements_by_cssdoesn't exist, it's calledfind_elements_by_css_selector. One should be able to look at the exception message and look back into documentation hereand figure out why. - Notice the difference between
find_element_by_css_selectorandfind_elements_by_css_selector? The first one finds the first matching element, the second one finds a list, so you need to use [0] to index. Hereis the API documentation. The reason why I use the latter, is because I copied your code, which I shouldn't.
回答by Das Bruno
browser.find_elements_by_xpath(".//input[@type='radio' and @value='SRF']")[0].click
This ended up being the fix. I was getting errors without the [0] there, that a list does not have a click() attribute (even though there was only 1 match). Thanks for the help user1177636!
这最终是修复。我在没有 [0] 的情况下遇到错误，即列表没有 click() 属性（即使只有 1 个匹配项）。感谢用户1177636的帮助！

First Radio button was not selected for me also. But after inserting Time it works for me.
也没有为我选择第一个单选按钮。但是在插入时间后它对我有用。
driver.find_element_by_class_name("login").click()
driver.find_element_by_id("email_create").send_keys("[email protected]")
driver.find_element_by_id("SubmitCreate").click()
time.sleep(2)
driver.find_element_by_css_selector("#id_gender2").click()
