c++与js脚本交互,C++调用JS函数JS调用C++函数

一、javascript调用c++,方法有两种

方案1：

1.html编写

<html>
<head>
</head>
<body>
<h1>
TEST
</h1>
<input type='button'name="xx3" value=调用c++函数 onclick="window.navigate('app:command&arg1=1&arg2=2')">
</body>
<script language="javascript">
function TestFunc()
{
alert("TestFunc");
}
</script>
</html>

2.C++的CHtmlView类重写OnBeforeNavigate2函数

void CAddGoogleMap_CHtmlView::OnBeforeNavigate2(LPCTSTR lpszURL, DWORD nFlags, LPCTSTR lpszTargetFrameName, CByteArray& baPostedData, LPCTSTR lpszHeaders, BOOL* pbCancel)
{
// TODO: Add your specialized code here and/or call the base class
CString strUrl = lpszURL;
if(strUrl.Left(4) == _T("app:"))
{
// cancel the common url navigate and call your c++ code here
*pbCancel = TRUE;
MessageBox("调用了C++函数", "来自对话框消息");
// call other c++ function here or parse the argument in the strUrl

}

CHtmlView::OnBeforeNavigate2(lpszURL, nFlags, lpszTargetFrameName, baPostedData, lpszHeaders, pbCancel);
}

方案2:

1.编写html

<html>

<head>

</head>

<body>

{

alert('start to call cpp here');

window.external.JavaScriptCallCpp('This is a test for call C++ in JavaScript');

}

</script>

</body>

<html>

2.C++代码

CString javaScriptName = _T("JavaScriptCallCpp");

}

二、C++调用javascript函数

1.编写html,如javascript调用c++的方案1的html

2.c++代码

void CAddGoogleMap_CHtmlView::OnTestSwap()
{
// call js function
CComPtr<IDispatch> spScript;
CComPtr<IHTMLDocument2> spDoc;
GetHtmlDocument()->QueryInterface(IID_IHTMLDocument2,(void**)&spDoc);//取得网页文档接口指针
spDoc->get_Script(&spScript);//取得脚本com接口

CComBSTR bstrMember("TestFunc");//javaScript函数名称
DISPID dispid = NULL;
HRESULT hr = spScript->GetIDsOfNames(IID_NULL,&bstrMember,1,
LOCALE_SYSTEM_DEFAULT,&dispid);//取得函数名对应 DISPID
DISPPARAMS dispparams;//根据实际函数情况填写函数参数,这里示例TestFunc函数没有参数据
memset(&dispparams, 0, sizeof dispparams);
dispparams.cArgs = 0;//参数个数
dispparams.rgvarg = new VARIANT[dispparams.cArgs];
dispparams.cNamedArgs = 0;

EXCEPINFO excepInfo;
memset(&excepInfo, 0, sizeof excepInfo);
CComVariant vaResult;
UINT nArgErr = (UINT)-1; // initialize to invalid arg
//执行JavaScript函数
hr = spScript->Invoke(dispid,IID_NULL,0,
DISPATCH_METHOD,&dispparams,&vaResult,&excepInfo,&nArgErr);

}
