Selenium Python绑定：如何在元素上执行JavaScript？ [英] Selenium Python bindings: how to execute JavaScript on an element?

问题描述

使用python selenium脚本触发selenium服务器运行JavaScript代码。它工作正常。

Have used python selenium script to trigger selenium server to run JavaScript code. It works fine.

drv.execute_script('<some js code>')

但是，我无法弄清楚如何在使用get_element_by _ *（）api检索的元素上运行javascript代码。例如，我

However, I can't figure out how to run javascript code on an element that was retrieved using get_element_by_*() api. For example, I

ele = get_element_by_xpath('//button[@id="xyzw"]');
#question: how do I change the "style" attribute of the button element?

如果我在浏览器的开发者控制台上，我可以将其作为

If I were on developer console of the browser, I can run it as

ele = $x('//button[@id="xyzw"]')[0]
ele.setAttribute("style", "color: yellow; border: 2px solid yellow;")

只是不知道如何在python selenium脚本中执行此操作。
提前致谢。

Just don't know how to do it in python selenium script. Thanks in advance.

推荐答案

execute_script 接受参数，因此您可以传递元素： / p>

execute_script accepts arguments, so you can pass the element:

drv.execute_script('arguments[0].setAttribute("style", "color: yellow; border: 2px solid yellow;")', ele)
