Question

我正在尝试使用Selenium WebDriver在Python中获取后台url属性。使用＆＃39; color＆＃39;和＆＃39;位置＆＃39;属性但没有背景＆＃39;或者＆＃39; background-url＆＃39;。

home = driver.find_element_by_id("link-home")
print(home.value_of_css_property("position"))
=> absolute

任何人都可以帮助我吗？

这是css：

#main-header a#link-home {
    background: url("data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAB8AAAATCAYAAABobNZCAAAAGXRFWHRTb2Z0d2FyZQBBZG9iZSBJbWFnZVJlYWR5ccllPAAAAOFJREFUeNpiPLRnNQMR4D8QM2KTsHUOYSAXMBFpMTKNLP6fgQLARKTFjDgcwEAry5Et5qeFA5iIsNgDiO9Baao6gImAxX5AvBGIhaC0H66ERw3LkS0OB2JQVmCDirFB+eHUcgATDosTgHgpksUMSA5YCpUHO+Dw3jX/KbUc2eI0IJ4PxMxQPgjPQmIzQ+XTKHUAE5rFOUA8E0l+JhJ/Jha5fGAhQ7YDGJFKuGogbkGXR7IoHUdKrwE6oJXSOG/BkfL/Q4MYV4nWQsvilWaAhVC04CkHaFq80hyMWj7yLAcIMADiujmyHco+MAAAAABJRU5ErkJggg==") no-repeat scroll 0px 0px transparent;
    left: 10px;
    padding-left: 23px;
    position: absolute;
    top: -102px;
    color: #DFEFFC;
}

我已经在 firefox 中使用background或background-url属性（使用firefox 35.0.1和selenium 2.45）重现了这个问题。

在Firefox中对我有用的解决方法：

print driver.execute_script("""
var element = arguments[0],
    style = element.currentStyle || window.getComputedStyle(element, false);

return style['background-image'];
""", body)

演示：

>>> from selenium import webdriver
>>> 
>>> driver = webdriver.Firefox()
>>> driver.get("http://www.w3schools.com/cssref/tryit.asp?filename=trycss_background")
>>> 
>>> driver.switch_to.frame("iframeResult")
>>> 
>>> body = driver.find_element_by_tag_name("body")
>>> 
>>> print driver.execute_script("""
... var element = arguments[0],
...     style = element.currentStyle || window.getComputedStyle(element, false);
... 
... return style['background-image'];
... """, body)
url("http://www.w3schools.com/cssref/smiley.gif")

或者，只需切换到webdriver.Chrome()。

如何在Python中获取background-url？
