<script> var scrollFunc = function (e) { var direct = 0; 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) { //当滑轮向下滚动时 alert("滑轮向下滚动");
以下代码实现判断页面的滚动条的滚动方向: var sign = 80;//定义默认的向上滚与向下滚的边界 window.onscroll = window.onresize = function(){ var oScrollTop=$(window).scrollTop(); if ( oScrollTop > 80) { //write your code } if ( oScrollTop < 80) { //write your code } if ( oScrollTop > s
在DICOM标准里,有三个TAG与成像的方向相关. 参考来源:Kitware关于DICOM方向的说明 http://public.kitware.com/IGSTKWIKI/index.php/DICOM_data_orientation 包括 1.Image Position (0020,0032): specifies the x, y, and z coordinates of the upper left hand corner of the image. In other words,
正常的判断屏幕方向的代码: /** 获取屏幕是否是竖屏 * @return */ @SuppressLint("SwitchIntDef") public boolean isScreenPortrait(){ int or = getRequestedOrientation(); switch (or) { case ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE :// 横屏 case ActivityInfo.SCREEN_ORIENTATIO
当我们使用鼠标连接到 MacBook 时,会发现无论怎么设置,鼠标和触摸板的滚动方向都是相反的,导致不能同时使用鼠标和触摸板 解决方法: 我安装了下面的程序,它只允许您反转鼠标的滚动行为: Scroll Reverser for Mac OS X 安装完成之后,只要设置如下即可让鼠标和触摸板的滚动方向保存一致
<script> var scrollFunc = function (e) { var direct = 0; 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) { //当滑轮向下滚动时 alert("滑轮向下滚动");
废话不多说,直接上代码 $(window).scroll(function(){ var before = $(window).scrollTop(); $(window).scroll(function() { var after = $(window).scrollTop(); if (before<after) { console.log('上'); before = after; }; if (before>after) { console.log('下'); before = aft
