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 class if ((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); }
