如何获取硒中元素的所有属性？

  • 772

关于主题的问题。

通过get_attribute(name)方法可以获取属性值，但是需要知道它的名字，所以该方法不适合。

作为测试示例，我建议显示input_el元素的所有属性：

# pip install selenium
from selenium import webdriver

driver = webdriver.Firefox()
driver.implicitly_wait(10)  # seconds
driver.get('https://ru.stackoverflow.com/')

input_el = driver.find_element_by_css_selector('input.s-input__search')
python

    解决方案可以通过使用execute_script(script, *args)方法：

    def get_attributes(driver, element) -> dict:
    return driver.execute_script(
        """
        let attr = arguments[0].attributes;
        let items = {}; 
        for (let i = 0; i < attr.length; i++) {
            items[attr[i].name] = attr[i].value;
        }
        return items;
        """,
        element
    )

    所有代码：

    # pip install selenium
from selenium import webdriver


def get_attributes(driver, element) -> dict:
    return driver.execute_script(
        """
        let attr = arguments[0].attributes;
        let items = {}; 
        for (let i = 0; i < attr.length; i++) {
            items[attr[i].name] = attr[i].value;
        }
        return items;
        """,
        element
    )


driver = webdriver.Firefox()
driver.implicitly_wait(10)  # seconds
driver.get('https://ru.stackoverflow.com/')

input_el = driver.find_element_by_css_selector('input.s-input__search')
attrs = get_attributes(driver, input_el)
print(attrs)
# {'aria-controls': 'top-search', 'aria-label': 'Поиск', 'autocomplete': 'off',
#  'class': 's-input s-input__search js-search-field ', 'data-action': 'focus->s-popover#show',
#  'data-controller': 's-popover', 'data-s-popover-placement': 'bottom-start', 'maxlength': '240',
#  'name': 'q', 'placeholder': 'Поиск...', 'type': 'text', 'value': ''}

driver.quit()
