在MFC对话框中嵌入web网页时事件失效问题

在MFC对话框中嵌入web网页时，网页初始化中添加事件无效

document.body.onkeydown = function ()
{//onkeydown="keydownbody()" 不能激发alert(event.keyCode);if(event.keyCode == 27)//VK_ESCAPE //String.fromcharcode('A');{if (external != null && external.map_is_full_screen() == 1){external.map_full_screen();}}
}

原来主线程截断了消息

BOOL CXXXXDlg::PreTranslateMessage(MSG* pMsg)
{// TODO: Add your specialized code here and/or call the base classif ((pMsg->message == WM_KEYDOWN)&&(pMsg->wParam == VK_ESCAPE)){m_pXXXManagerDlg->AreaMessage(pMsg);//if(m_hMapGWnd)::SendMessage(m_hMapGWnd,pMsg->message,pMsg->wParam,pMsg->lParam);//使用上面的语句又会被CXXXXDlg::PreTranslateMessage(MSG* pMsg)拦截，必须使用接口方法或者自定义消息。return TRUE;}
//...return CDialog::PreTranslateMessage(pMsg);
}
