如何使用硒更改元素类属性值 [英] How to change element class attribute value using selenium
问题描述
我丢失了凭据..所以我正在创建这个新线程.这里有一个老问题，如果有帮助的话:如何单击按钮用python投票
I lost my credentials.. so I'm creating this new thread. The old question it here if it helps: How to click a button to vote with python
我想更改此行:
<a data-original-title="I like this faucet" href="#" class="vote-link up" data-faucet="39274" data-vote="up" data-toggle="tooltip" data-placement="top" title=""><span class="glyphicon glyphicon-thumbs-up"></span></a>
对此:
<a data-original-title="I like this faucet" href="#" class="vote-link up voted" data-faucet="39274" data-vote="up" data-toggle="tooltip" data-placement="top" title=""><span class="glyphicon glyphicon-thumbs-up"></span></a>
以便设置投票，将vote-link up更改为vote-link up voted.
So that the vote is set changing vote-link up to vote-link up voted.
但是问题是，在该站点中，有几个项目需要投票，并且元素"data-faucet"发生了变化.如果我使用此脚本:
But the problem is that in that site, there are severals items to vote, and the element "data-faucet" changes. If I use this script:
from selenium import webdriver
driver = webdriver.Firefox()
driver.get("linkurl")
element = driver.find_element_by_css_selector(".vote-link.up")
element_attribute_value = element.get_attribute("data-faucet")
if element_attribute_value == "39274":
print ("Value: {0}".format(element_attribute_value))
driver.quit()
但是它不显示任何内容，因为第一个属性值具有另一个数字.
But it obsiusly doesn't print anything, cause the first attribute value has another number. How can I select my line with the input of the number of data-faucet element, so I can replace it with vote-link up voted?
我只能做这种硒吗?没有使用真正的浏览器还有另一种方法吗?
I only can do this selenium? Is there another way without using a real browser?
无论如何，这是网页的结构:
Anyway, this is the structure of the webpage:
<html>
<head></head>
<body role="document">
<div id="static page" class="container-fluid">
<div id="page" class="row"></div>
<div id="faucets-list">
<tbody>
<tr class=""></tr>
<tr class=""></tr>
<tr class=""></tr>
<tr class=""></tr>
# an infinite number of nodes, until there's mine
<tr class="">
<td class="vote-col">
<div class="vote-box">
<div class="vote-links">
<a class="vote-link up" data-original-title="I like this faucet" href="#" data-faucet"39274" data-vote"up" data-toggle"tooltip" data-placement="top" title=""></a>
网站是这样的: https://faucetbox.com/en/list/BTC
推荐答案
来自注释:-
是否要与具有
data-faucet属性值39274的元素进行交互?
Do you want to interact with element which has
data-faucetattribute value39274??
确实！就是我想做的事！
exatly! just what I want to do!
您应尝试按以下方式使用css_selector:-
You should try using css_selector as below :-
element = driver.find_element_by_css_selector(".vote-link.up[data-faucet = '39274']")
好..现在，如果我在print(element)终端上显示以下内容，它实际上会选择某项内容:
<selenium.webdriver.remote.webelement.WebElement (session="d54ae232-6d42-455f-a130-097be89adf1e", element="{96385594-1725-4843-bfed-d5a4e7b9af41}")>.因此，既然我已经选择了它，那么如何替换"vote-link up"?带有投票链接投票"?
ok.. now it selects something in fact if I print(element) terminal shows:
<selenium.webdriver.remote.webelement.WebElement (session="d54ae232-6d42-455f-a130-097be89adf1e", element="{96385594-1725-4843-bfed-d5a4e7b9af41}")>.so now that I've selected it, how can I replace "vote-link up" with "vote-link up voted"?
您可以使用execute_script()替换class属性值，如下所示:-
You can replace class attribute value using execute_script() as below :-
driver.execute_script("arguments[0].setAttribute('class','vote-link up voted')", element)
