分享一个js实现判断鼠标滚轮的上下滚动: <script type="text/javascript"> var scrollFunc = function (e) { e = e || window.event; if (e.wheelDelta) { //判断浏览器IE,谷歌滑轮事件 if (e.wheelDelta > 0) { //当滑轮向上滚动时 alert("滑轮向上滚动"); } if (e.wheelDelta < 0) {…
如何让DbGrid支持鼠标滚轮滚动 在主窗体上加一个ApplicationEvents控件(控件在Additional面板中), 在它的OnMessage事件中加入下述代码,一切搞定-! procedure TFrm_main_usermanager.ApplicationEvents1Message(var Msg: tagMSG; var Handled: Boolean); ..] of char; begin //给DBGrid加上鼠标滚轮 if Msg.message <> WM_M…
