它没有给出错误,我把a console.log('loaded userscript wifi-autologin'),console.log作品,但document.addEventListener的预期效果不会发生.在进行了一些调试之后,让它打印出调用了addEventListener,我发现它没有被调用.
脚本来源:
// ==UserScript==
// @name wifi-autologin
// @namespace lf-ns
// @description Hopefully autologins to a captive portal
// @include *://1.1.1.1/*
// @version 1
// @run-at document-end
// ==/UserScript==
document.addEventListener('load', submitAction);
每当PulseAudio中的接收器状态发生变化(例如变为非活动状态)时,我都会尝试调用D-Bus信号处理程序.不幸的是,它没有被调用,我坦率地不确定为什么.
import dbus
import dbus.mainloop.glib
from gi.repository import GObject
dbus.mainloop.glib.DBusGMainLoop(set_as_default=True)
bus = dbus.SessionBus()
def signal_handler(*args, **kwargs):
print('sig: ', args, kwargs)
def connect():
import os
if 'PULSE_DBUS_SERVER' in os.environ:
address = os.environ['PULSE_DBUS_SERVER']
else:
bus = dbus.SessionBus()
server_lookup = bus.get_object("org.PulseAudio1", "/org/pulseaudio/server_lookup1")
address = server_lookup.Get("org.PulseAudio.ServerLookup1", "Address", dbus_interface="org.freedesktop.DBus.Properties")
return dbus.connection.Connection(address)
conn = connect()
core = conn.get_object(object_path='/org/pulseaudio/core1')
core.connect_to_signal('StateUpdated', signal_handler)
core.ListenForSignal('org.PulseAudio.Core1.Device.StateUpdated', dbus.Array(signature='o'), dbus_interface='org.PulseAudio.Core1')
loop = GObject.MainLoop()
loop.run()
我正试图使用twitter bootstrap网站上提供的示例来解决问题.当我尝试使用此代码时,单击链接以折叠内容不会执行任何操作.这是我的代码:

</div> …页面上有一个函数,我想在加载后调用它.我不拥有该页面,因此我无法在其中插入任何html.您能否提供一些具体示例,如何使用镀铬扩展或greasemonkey进行此操作？(功能是submitAction()).
我有一些带有一些<hr/>元素的导航.优选地,在纯CSS(3？)中,如何将水平规则的宽度设置为自动减去X个像素数？
这并不重复这个问题,因为它等于负填充,这是不可能的.
