到Javascript字符串？

Answer 1

您可以使用mainloop或类似内容获取元素，然后使用from kivy.app import App from kivy.uix.boxlayout import BoxLayout from kivy.lang import Builder from kivy.base import EventLoop Builder.load_string(''' <MyWidget>: Button: text: 'test' on_press: print('doing my job') ''') # https://github.com/kivy/kivy/blob/master/kivy/core/window/window_sdl2.py#L630 def mainloop(self): # replaced while with if if not EventLoop.quit and EventLoop.status == 'started': try: self._mainloop() except EventLoop.BaseException as inst: # use exception manager first r = EventLoop.ExceptionManager.handle_exception(inst) if r == EventLoop.ExceptionManager.RAISE: EventLoop.stopTouchApp() raise else: pass class MyWidget(BoxLayout): pass if __name__ == '__main__': from kivy.base import runTouchApp runTouchApp(MyWidget(), slave=True) # monkey patch EventLoop.window.mainloop = mainloop while True: EventLoop.window.mainloop(EventLoop.window) print('do the other stuff') if EventLoop.quit: break获取其HTML（包括元素自带标记）：

querySelector

假设您需要的元素是具有类outerHTML的文档中的第一个元素。您必须根据需要调整选择器，您可以使用任何有效的CSS选择器。请注意，如果您只需要搜索文档的一部分，那么alert(document.querySelector(".g").outerHTML);也可用于单个元素（而不是整个文档），并且有一个表单可以返回 all <的列表/ em>匹配（g），如果你需要循环。

示例：

＆＃13;
＆＃13;
querySelector
＆＃13;
querySelectorAll
＆＃13;
＆＃13;
＆＃13;

Answer 2
