该Object "wb" 其实就是IE内置打印控件IEWebBrowser,设定 Width 和 Height 为0,在界面上就不显示控件的形状。关于这个组件还有其它用法,列举如下：
WebBrowser.ExecWB(1,1) 打开
Web.ExecWB(2,1) 关闭现在所有的IE窗口，并打开一个新窗口
Web.ExecWB(4,1) 保存网页
Web.ExecWB(6,1) 打印
Web.ExecWB(6,6) 直接打印
Web.ExecWB(7,1) 打印预览
Web.ExecWB(8,1) 打印页面设置
Web.ExecWB(10,1) 查看页面属性
Web.ExecWB(17,1) 全选
Web.ExecWB(22,1) 刷新
Web.ExecWB(45,1) 关闭窗体无提示

<input name=Button onClick=document.all.WebBrowser.ExecWB(2,1) type=button value=关闭所有>

关键字 IEWebBrowser﹑execWB﹑打印
IEWebBrowser这个组件的execWB方法整理
1. <object id="WebBrowser" width=0 height=0 classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"></object>
2. 调用方法。
WebBrowser.ExecWB nCmdID, nCmdExecOpt, [pvaIn], [pvaOut]
3. 参数说明。
(a).nCmdID
OLECMDID_OPEN = 1,
OLECMDID_NEW = 2,
OLECMDID_SAVE = 3,
OLECMDID_SAVEAS = 4,
OLECMDID_SAVECOPYAS = 5,
OLECMDID_PRINT = 6,
OLECMDID_PRINTPREVIEW = 7,
OLECMDID_PAGESETUP = 8,
OLECMDID_SPELL = 9,
OLECMDID_PROPERTIES = 10,
OLECMDID_CUT = 11,
OLECMDID_COPY = 12,
OLECMDID_PASTE = 13,
OLECMDID_PASTESPECIAL = 14,
OLECMDID_UNDO = 15,
OLECMDID_REDO = 16,
OLECMDID_SELECTALL = 17,
OLECMDID_CLEARSELECTION = 18,
OLECMDID_ZOOM = 19,
OLECMDID_GETZOOMRANGE = 20
OLECMDID_UPDATECOMMANDS = 21
OLECMDID_REFRESH = 22
OLECMDID_STOP = 23
OLECMDID_HIDETOOLBARS = 24
OLECMDID_SETPROGRESSMAX = 25
OLECMDID_SETPROGRESSPOS = 26
OLECMDID_SETPROGRESSTEXT = 27
OLECMDID_SETTITLE = 28
OLECMDID_SETDOWNLOADSTATE = 29
OLECMDID_STOPDOWNLOAD = 30
上面的关键词都可以在浏览器的菜单里面找到对应的选项﹐大家一看就明白的﹗
(b).nCmdExecOpt
OLECMDEXECOPT_DODEFAULT = 0,
OLECMDEXECOPT_PROMPTUSER = 1,
LECMDEXECOPT_DONTPROMPTUSER = 2,
OLECMDEXECOPT_SHOWHELP = 3
对于这个参数﹐一般来说﹐选1就可以了。
这是调用IE的”另存为”功能的示例﹕
<object id="WebBrowser" width=0 height=0 classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"></object>
<A href="javascript:WebBrowser.ExecWB(4,1);">Save-存储</A>
</xmp>
