调用过程分三步（在此以打印预览为例）：
一、 在页面加入Object对象：
<object id="WebBrowser" classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2" height="0" width="0">
</object>
</object>
二、通过页面控件触发：
<input type="button" name="Button" value="打印预览" onClick="document.all.WebBrowser.ExecWB(7,1)" />
三、某些时候需要设置打印区域，于是可以在页面加载时或Body的onbeforeprint和onafterprint事件进行处理，如下：
<body onbeforeprint="DivId.style.display= 'none';" onafterprint="DivId.style.display = 'block';">
从下内容是ExecWB方法的详细说明：- 调用方法： WebBrowser.ExecWB(nCmdID, nCmdExecOpt, [pvaIn], [pvaOut])
- 参数说明：
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。
