用python编写的JS控制台
jsConsole的Python项目详细描述
JS控制台
为python编写的JavaScript控制台
什么是jsConsole？
JavaScript让你可以像在python控制台中那样使用JavaScript控件！在
用法
只要从模块中导入所有内容，就可以开始了！在
>>>fromjsConsoleimport*#### And now you can use classes like document, window, Math or console from Python!>>>console.log('jsConsole is ready!')'jsConsole is ready!'>>>window.open('https://google.com','_self')# Opens google.com on the browser #>>>defhello():...print('Hello')...>>>document.getElementsByClassName('RNNXgb')[0].addEventListener('click',hello)### Adding an event listener to the search bar from google.com which executes hello() when clicked.>>>window.kill()# Needed to kill the browser (for it not to stay in the background even with Python quited)
安装
用PyPI（pip）Python依赖项/模块管理器安装它。在
浏览器配置
默认情况下，jsConsole使用运行在Chromium上的pyppeeer来执行JavaScript。在
您可以配置要与jsConsole.internal.config一起使用的浏览器
>>>importjsConsole.internal.configasjsConsoleConfig>>>jsConsoleConfig.layer# defines the layer (Selenium of Pyppeteer) you want to use --> String>>>jsConsoleConfig.executable_path# Sets the executable path of the browser you want to use. --> String>>>jsConsoleConfig.no_sandbox# Sets wether you want to use the --no-sandbox argument whie opening the browser or not (useful for Linux) --> bool>>>jsConsoleConfig.args# Sets this to pass arguments while opening the browser. --> Needs to be a list>>>jsConsoleConfig.headless# Sets wether you want the browser to be headless or not with Selenium --> bool>>>jsConsoleConfig.browsername# Sets the browser you want to use with Selenium ('Chrome', 'Firefox' and 'PhantomJS' are currently supported) --> String"""Default Configuration is:layer = 'Selenium'executable_path = ''no_sandbox = Falseargs = []headless = Truebrowsername = 'Chrome'"""## Experiment and try different browsers and layers to find the one that fits the best for you. I've personnaly tried my module with the default configurations.###### If you don't want to worry about drivers and browsers you can use Pyppeteer which will download, install and set up a browser for you.>>>fromjsConsoleimport*...
jsConsole特定的函数/方法和类。
- 在浏览器.kill（）或窗户。杀了（）
用于终止启动时打开的浏览器实例，以防止它在停止脚本/python执行后仍在后台打开。在
Check your activity monitor (top, htop, activity monitor, etc.) if there isn't any non-used browsers opened as it may happen when using Selenium and other browser control softwares.
- 浏览器（浏览器对象）
包含有关当前打开的浏览器实例的多个信息：
- browser: The browser instance, a new page object if using Pyppeteer or a driver instance if using Selenium
- layer: The name of the layer used (Selenium or Pyppeteer)
- executable_path: The executable path (if specified one) of the browser in use
- browsername: The name of the browser in use (i.e Chrome, Firefox)
- no_sandbox: Wether or not you activated the option no-sandbox (useful for Linux users)
- headless: If you opened the browser instance headlessly (works for Selenium)
- args: The arguments passed (if configured) while opening the browser
- drivername: The name of the driver in use
- connected: Wether or not you are connected to the browser
- areClassesInitialized: Internal variable to indicate if the JavaScript are correctly initialized
- list_of_variables: Internal variable which tells the variables ID created by jsConsole (i.e when using addEventListener or setTimeout)
- dict_of_ids = Internal variable which tells the different setTimeout/setInterval IDs that had been created and if each of them should be enabled or not.
- ids_to_thread = Internal variable which tells the different setTimeout/setInterval IDs that had been created and their corresponding thread.
- 新鲜（）
返回一个具有全新文档和窗口类的元组（在加载新页面后）
这样使用：
>>>document,window,history=fresh()Whichreturnsanewdocument(_Document)objectinthedocumentvariable,anewwindow(_Window)objectinthewindowvariableandanewhistory(_History)objectinthehistoryvariable.## I can't provide a new document and window in real-time, seamlessly (even though I tried) because of the way they work.
- newDocument（）：
返回一个新的document（\u document）对象
- newWindow（）：
返回一个新窗口（_window）对象
- newHistory（）：
返回一个新的history（\u history）对象
- 求值（）：
如果需要，评估一段JavaScript代码（即还不可用）
return_value=True adds "
return" in front of the snippet of code if you want the value to be returned while using Selenium
- 在文档.window以及窗口.window将返回一条错误消息，因为我没有找到在不创建递归错误的情况下链接它们的方法。在
您可以在setTimeout（）、clearInterval（）和addEventListener中使用python函数。
你应该能够像用JavaScript写代码一样编写代码。
