JavaScript调用C++

JavaScript调用C++
方案一：

// html & JavaScript

...

<button value="Click me" onclick="window.navigate('app:command&arg1=1&arg2=2')" />

...

// 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
```
Code
```
// 修改App
```
