JS实现跑马灯效果,添加到报表块的初始化事件中,但在决策系统中预览决策报表时,点击全屏,滚动速度会加快,求解决办法。 代码:setTimeout(function() { //隐藏报表块report0的滚动条(此报表块名为report0,根据具体情况修改) $("div[widgetname=REPORT0_C]").find(".frozen-north")[0].style.overflow = "hidden"; $("div[widgetname=REPORT0_C]").find(".frozen-center")[0].style.overflow = "hidden"; }, 1000); window.flag = true; //鼠标悬停,滚动停止 setTimeout(function() { $(".frozen-center").mouseover(function() { window.flag = false; }); //鼠标离开,继续滚动 $(".frozen-center").mouseleave(function() { window.flag = true; }); var old = -1; var interval = setInterval(function() { if(window.flag) { currentpos = $(".frozen-center")[0].scrollTop; if(currentpos == old) { $(".frozen-center")[0].scrollTop = 0; } else { old = currentpos; //以25ms间隔每次滚动1.5PX $(".frozen-center")[0].scrollTop = currentpos + 1.0; } } }, 25); }, 1000); |
