1.注冊C++函數。
//注冊回調函數宏
//根據不同需要支持注冊兩個函數原型，注意CONNECT_JS_CALL_SIMPLE_HANDLER中注冊的函數
//需要提前和HTML調用協調好，參數必須都為字符，負責會引起未知問題
#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.被調函數聲明。
static int OpenCustomStockDlg(DISPPARAMS* params, VARIANT* retval , void* pContext);
3.被調函數實現。
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編寫
<HTML>
<HEAD><TITLE>js 按鍵記錄</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"); //關掉鍵盤精靈界面，傳clear則清空鍵盤精靈字符串，不傳或者為空則只關閉界面
}
}
else
{
if (external != undefined )
{
external.OpenCustomStockDlg(currKey); //向鍵盤精靈傳字符
}
}
$("test1").focus();//設置焦點
}
</script>
<body >
<input type="text" id="test1" onkeypress="keypress(event);"/>
<p>文本框內按鍵觸發鍵盤精靈</p>
