我想更改班级名称，但这对我不起作用。

<div class="vcp-controls-panel vcp-playing hide">

FullXpath：

/html/body/div[1]/div/div/div/div[2]/div/div/div[1]/div[1]/div[1]/div/div[1]/div[3]/div/div[1]/div/div[1]/div[9]/div[4]

我想将 vcp-playing hide 更改为 vcp-playing show 但它不起作用

selects = driver.find_element_by_class_name("vcp-playing hide")
    for select in selects:
        driver.execute_script("arguments[0].setAttribute('class', 'vcp-playing show')", select)

由于现有元素已经设置了 classname 属性：

<div class="vcp-controls-panel vcp-playing hide">

您可以通过 removeAttribute( ) 使用 setAttribute() 如下：

selects = driver.find_elements(By.CSS_SELECTOR, "div.vcp-controls-panel.vcp-playing.hide")
for select in selects:
    driver.execute_script("arguments[0].removeAttribute('class')", select);
    driver.execute_script("arguments[0].setAttribute('class','vcp-controls-panel vcp-playing show')", select)

注意：您必须添加以下内容进口：

from selenium.webdriver.common.by import By

As the existing element already have the classname attribute set:

<div class="vcp-controls-panel vcp-playing hide">

You can remove the existing attributes through removeAttribute() set the new attributes using setAttribute() as follows:

selects = driver.find_elements(By.CSS_SELECTOR, "div.vcp-controls-panel.vcp-playing.hide")
for select in selects:
    driver.execute_script("arguments[0].removeAttribute('class')", select);
    driver.execute_script("arguments[0].setAttribute('class','vcp-controls-panel vcp-playing show')", select)

Note : You have to add the following imports :

from selenium.webdriver.common.by import By

完全用 javascript 来做怎么样？

driver.execute_script("""
    selects = document.querySelectorAll('.vcp-playing.hide')
    selects.forEach(e => e.setAttribute('class', 'vcp-playing show'))
""")

how about do it completely in javascript

driver.execute_script("""
    selects = document.querySelectorAll('.vcp-playing.hide')
    selects.forEach(e => e.setAttribute('class', 'vcp-playing show'))
""")
