JavaScript调用C++

方案一：

// html & JavaScript

...

...

// C++: 响应的消息函数OnBeforeNavigat2

virtual void OnBeforeNavigate2( LPCTSTR lpszURL, DWORD nFlags, LPCTSTR lpszTargetFrameName,

CByteArray& baPostedData, LPCTSTR lpszHeaders, BOOL* pbCancel );

// C++ code goes here

Code

方案二：

// html & javaScript

...

function CallCpp()

{

alert('start to call cpp here');

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

}

<button onclick="CallCpp()" >JavaScript访问C++代码</button>

...

// C++ code goes here

CString javaScriptName = _T("JavaScriptCallCpp");

#define DISPID_CallCppFromJs 1

// 实现IDispatch 接口

Code

// 改写COleControlSit
