Watir点击IE的提示条。

用Watir点击类似于上图的提示条。

首先引用前面一片文章提到过的模拟鼠标操作的一个模块。

module WindowsInput
  # Windows API functions
  SetCursorPos = Win32API.new('user32','SetCursorPos', 'II', 'I')
  SendInput = Win32API.new('user32','SendInput', 'IPI', 'I')
  # Windows API constants
  INPUT_MOUSE = 0
  MOUSEEVENTF_LEFTDOWN = 0x0002
  MOUSEEVENTF_LEFTUP = 0x0004
  MOUSEEVENTF_RIGHTDOWN = 0x0008
  MOUSEEVENTF_RIGHTUP = 0x0010

  module_function

  def send_input(inputs)
    n = inputs.size
    ptr = inputs.collect {|i| i.to_s}.join # flatten arrays into single string
    SendInput.call(n, ptr, inputs[0].size)
  end

  def create_mouse_input(mouse_flag)
    mi = Array.new(7, 0)
    mi[0] = INPUT_MOUSE
    mi[4] = mouse_flag
    mi.pack('LLLLLLL') # Pack array into a binary sequence usable to SendInput
  end

  def move_mouse(x, y)
    SetCursorPos.call(x, y)
  end

  def right_click
    rightdown = create_mouse_input(MOUSEEVENTF_RIGHTDOWN)
    rightup = create_mouse_input(MOUSEEVENTF_RIGHTUP)
    send_input( [rightdown, rightup] )
  end

  def left_click
    leftdown = create_mouse_input(MOUSEEVENTF_LEFTDOWN)
    leftup = create_mouse_input(MOUSEEVENTF_LEFTUP)
    send_input( [leftdown, leftup] )
  end
end 

然后通过DOM得到坐标，直接点击……

require 'watir'
require 'Win32API'
require 'WindowsInput'

ie = Watir::IE.attach(:title, "test page")
ie.bring_to_front
x = ie.document.parentWindow.screenLeft.to_i + 10
y = ie.document.parentWindow.screenTop.to_i - 10
WindowsInput.move_mouse(x, y)
WindowsInput.left_click

剩下的事情就根据具体请过具体解决了……
