如何在Selenium和Python中使用类型查找元素 [英] How to find element using type in Selenium and Python

问题描述

我有下面的html代码.

I have the below html code.

<div align="center">
    <input type="file" name="filePath"><br>
    <input type="Submit" value="Upload File"><br>
</div>

我正在尝试使用Selenium和Python查找两个元素文件"和提交".下面是我尝试使用的代码.

I am trying to find the two elements "file" and "submit" using Selenium with Python. Below is the code I have tried to use.

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

# create a new Firefox session
driver = webdriver.Chrome()

# Maximize the browser window
driver.maximize_window()

# Enter the url to load
driver.get("<<MY PAGE TO LOAD>>")

# Wait for the page to load
driver.implicitly_wait(5)

# find the upload file type and pass a test value
upload_field = driver.find_element_by_partial_link_text('file')
upload_field.clear()
upload_field.send_keys("test")

运行此代码时，我可以在Chrome浏览器中成功加载页面，但出现以下异常.

When I run this code, I am able to load the page successfully in the Chrome browser but I get the below exception.

# Exception when trying to get element by type
Traceback (most recent call last):
  File "C:\Users\TEST\Desktop\Test.py", line 33, in <module>
    upload_field = driver.find_element_by_partial_link_text('file')

    return self.find_element(by=By.PARTIAL_LINK_TEXT, value=link_text)

    'value': value})['value']

我查看了此处提供的解决方案但这也会引发错误.我目前正在将Python 3.6.4 x64与Selenium 3.8.1结合使用.我的操作系统是Windows 7 x64位.如何在html中获取带有类型"的元素?

I looked at the solution provided here but this too is throwing an error. I am currently using Python 3.6.4 x64 with Selenium 3.8.1. My OS is Windows 7 x64 bit. How can I get elements with 'type' in html?

推荐答案

结帐文档查找元素.我发现xpaths或css选择器特别强大，因为它们具有极强的通用性.

Checkout the docs on finding elements. I find xpaths or css selectors particularly powerful because they are extremely generalizable.

upload_field = driver.find_element_by_xpath("//input[@type='file']")

css选择器

upload_field = driver.find_element_by_css_selector("input[name='filePath'][type='file']")
