[英]How can I change an attribute value in the DOM using Selenium and Python
[英]How to change the value of the class attribute of an element using Python and Selenium
我想更改 class 名稱,但它對我不起作用。
<div class="vcp-controls-panel vcp-playing hide">
全路徑:
/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]
我想將vcp-playing hide
更改為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)
由於現有元素已經設置了classname屬性:
<div class="vcp-controls-panel vcp-playing hide">
您可以通過removeAttribute()
刪除現有屬性,使用setAttribute()
) 設置新屬性,如下所示:
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:您必須添加以下導入:
from selenium.webdriver.common.by import By
在 javascript 中完成它怎么樣
driver.execute_script("""
selects = document.querySelectorAll('.vcp-playing.hide')
selects.forEach(e => e.setAttribute('class', 'vcp-playing show'))
""")
