IEWebBrowser组件的execWB方法 haley_hj（原作）

我对IEWebBrowser这个组件的execWB方法整理了一下﹐希望对大家有所帮助。 
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>
