1.注册C++函数。

//注册回调函数宏
//根据不同需要支持注册两个函数原型，注意CONNECT_JS_CALL_SIMPLE_HANDLER中注册的函数
//需要提前和HTML调用协调好，参数必须都为字符，负责会引起未知问题
#define CONNECT_JS_CALL_HANDLER(name, func, pContext) do \
{\
	if (!CBKCallBackFuncContainer::GetFuncPtr()->NameId(L#name)) \
		CBKCallBackFuncContainer::GetFuncPtr()->ConnectJSFuncHandler(L#name, (JSCallbackFunction)&func, FALSE, pContext);\
} while (FALSE);


	CONNECT_JS_CALL_HANDLER(OpenCustomStockDlg, (JSCallbackFunction)&OpenCustomStockDlg, this);

2.被调函数声明。

	static int		OpenCustomStockDlg(DISPPARAMS* params, VARIANT* retval , void* pContext);

3.被调函数实现。

int		CXXWindow::OpenCustomStockDlg(DISPPARAMS* params, VARIANT* retval , void* pContext)
{
	CFinancialMainWindow* _pThis = static_cast<CFinancialMainWindow*>(pContext);
	ATLASSERT(_pThis);
	CString strCur = "0";
	if (params->cArgs == 1)
	{
		strCur = params->rgvarg[0];
	}

	//_pThis->OpenLogingSetDlg(StrToLong(strCur));
	CString strPara = _pThis->Get_SignPara();
	CustomStockSynchronous dlgCustomStock(strPara);
	dlgCustomStock.DoModal();

	return 0;
}

4.html编写

<HTML>
<HEAD><TITLE>js 按键记录</TITLE>
</HEAD>
<script type="text/javascript">
function $(s){return document.getElementById(s)?document.getElementById(s):s;}

function keypress(e)
{
var e=e||event;
var currKey=e.keyCode||e.which||e.charCode;
if (currKey == 27)//ESC = 27
{
	if (external != undefined)
	{
		external.KeyElvesClose("clear");	//关掉键盘精灵界面，传clear则清空键盘精灵字符串，不传或者为空则只关闭界面
	}
}
else
{
	if (external != undefined )
	{
	    external.OpenCustomStockDlg(currKey); //向键盘精灵传字符
	}
}
$("test1").focus();//设置焦点
}

</script>
<body  >

<input type="text"  id="test1" onkeypress="keypress(event);"/>
<p>文本框内按键触发键盘精灵</p>
</body>
</HTML>
