今天整理一个在织梦文章列表向上滚动的知识点,实例是http://www.cctv-ss.com/ 首页的滚动文章列表,如下图: 其实方法很简单 1、在需要滚动文章列表的地方,用织梦的文章列表标签调用有“滚动”属性的文章。假设滚动文章列表的div 是<DIV id=ScrollMe> ,文章列表的代码如下: <DIV id=ScrollMe> {dede:artlist row='4' flag=s} <A title=[field:title/] href="[field:arcurl/]">[field:title/]</A><SPAN>[field:pubdate function="MyDate('Y/m/d H:i',@me)"/]</SPAN><BR> {/dede:artlist} </DIV> 2、在添加js代码,代码如下: (1)下面这段代码放到文章列表代码的上面: <SCRIPT>function srcMarquee(){ this.ID = document.getElementById(arguments[0]); if(!this.ID){this.ID = -1;return;} this.Direction = this.Width = this.Height = this.DelayTime = this.WaitTime = this.Correct = this.CTL = this.StartID = this.Stop = this.MouseOver = 0; this.Step = 1; this.Timer = 30; this.DirectionArray = {"top":0 , "bottom":1 , "left":2 , "right":3}; if(typeof arguments[1] == "number")this.Direction = arguments[1]; if(typeof arguments[2] == "number")this.Step = arguments[2]; if(typeof arguments[3] == "number")this.Width = arguments[3]; if(typeof arguments[4] == "number")this.Height = arguments[4]; if(typeof arguments[5] == "number")this.Timer = arguments[5]; if(typeof arguments[6] == "number")this.DelayTime = arguments[6]; if(typeof arguments[7] == "number")this.WaitTime = arguments[7]; if(typeof arguments[8] == "number")this.ScrollStep = arguments[8] this.ID.style.overflow = this.ID.style.overflowX = this.ID.style.overflowY = "hidden"; this.ID.noWrap = true; this.IsNotOpera = (navigator.userAgent.toLowerCase().indexOf("opera") == -1); if(arguments.length >= 7)this.Start(); } srcMarquee.prototype.Start = function(){ if(this.ID == -1)return; if(this.WaitTime < 800)this.WaitTime = 800; if(this.Timer < 20)this.Timer = 20; if(this.Width == 0)this.Width = parseInt(this.ID.style.width); if(this.Height == 0)this.Height = parseInt(this.ID.style.height); if(typeof this.Direction == "string")this.Direction = this.DirectionArray[this.Direction.toString().toLowerCase()]; this.HalfWidth = Math.round(this.Width / 2); this.BakStep = this.Step; this.ID.style.width = this.Width; this.ID.style.height = this.Height; if(typeof this.ScrollStep != "number")this.ScrollStep = this.Direction > 1 ? this.Width : this.Height; var msobj = this; var timer = this.Timer; var delaytime = this.DelayTime; var waittime = this.WaitTime; msobj.StartID = function(){msobj.Scroll()} msobj.Continue = function(){ if(msobj.MouseOver == 1){ setTimeout(msobj.Continue,delaytime); } else{ clearInterval(msobj.TimerID); msobj.CTL = msobj.Stop = 0; msobj.TimerID = setInterval(msobj.StartID,timer); } } msobj.Pause = function(){ msobj.Stop = 1; clearInterval(msobj.TimerID); setTimeout(msobj.Continue,delaytime); } msobj.Begin = function(){ msobj.ClientScroll = msobj.Direction > 1 ? msobj.ID.scrollWidth : msobj.ID.scrollHeight; if((msobj.Direction <= 1 && msobj.ClientScroll <msobj.Height) || (msobj.Direction > 1 && msobj.ClientScroll <msobj.Width))return; msobj.ID.innerHTML += msobj.ID.innerHTML; msobj.TimerID = setInterval(msobj.StartID,timer); if(msobj.ScrollStep < 0)return; msobj.ID.onmousemove = function(event){ if(msobj.ScrollStep == 0 && msobj.Direction > 1){ var event = event || window.event; if(window.event){ if(msobj.IsNotOpera){msobj.EventLeft = event.srcElement.id == msobj.ID.id ? event.offsetX - msobj.ID.scrollLeft : event.srcElement.offsetLeft - msobj.ID.scrollLeft + event.offsetX;} else{msobj.ScrollStep = null;return;} } else{msobj.EventLeft = event.layerX - msobj.ID.scrollLeft;} msobj.Direction = msobj.EventLeft > msobj.HalfWidth ? 3 : 2; msobj.AbsCenter = Math.abs(msobj.HalfWidth - msobj.EventLeft); msobj.Step = Math.round(msobj.AbsCenter * (msobj.BakStep*2) / msobj.HalfWidth); } } msobj.ID.onmouseover = function(){ if(msobj.ScrollStep == 0)return; msobj.MouseOver = 1; clearInterval(msobj.TimerID); } msobj.ID.onmouseout = function(){ if(msobj.ScrollStep == 0){ if(msobj.Step == 0)msobj.Step = 1; return; } msobj.MouseOver = 0; if(msobj.Stop == 0){ clearInterval(msobj.TimerID); msobj.TimerID = setInterval(msobj.StartID,timer); }}} setTimeout(msobj.Begin,waittime); } srcMarquee.prototype.Scroll = function(){ switch(this.Direction){ case 0: this.CTL += this.Step; if(this.CTL >= this.ScrollStep && this.DelayTime > 0){ this.ID.scrollTop += this.ScrollStep + this.Step - this.CTL; this.Pause(); return; } else{ if(this.ID.scrollTop >= this.ClientScroll){this.ID.scrollTop -= this.ClientScroll;} this.ID.scrollTop += this.Step; } break; case 1: this.CTL += this.Step; if(this.CTL >= this.ScrollStep && this.DelayTime > 0){ this.ID.scrollTop -= this.ScrollStep + this.Step - this.CTL; this.Pause(); return; } else{ if(this.ID.scrollTop <= 0){this.ID.scrollTop += this.ClientScroll;} this.ID.scrollTop -= this.Step; } break; case 2: this.CTL += this.Step; if(this.CTL >= this.ScrollStep && this.DelayTime > 0){ this.ID.scrollLeft += this.ScrollStep + this.Step - this.CTL; this.Pause(); return; } else{ if(this.ID.scrollLeft >= this.ClientScroll){this.ID.scrollLeft -= this.ClientScroll;} this.ID.scrollLeft += this.Step; } break; case 3: this.CTL += this.Step; if(this.CTL >= this.ScrollStep && this.DelayTime > 0){ this.ID.scrollLeft -= this.ScrollStep + this.Step - this.CTL; this.Pause(); return; } else{ if(this.ID.scrollLeft <= 0){this.ID.scrollLeft += this.ClientScroll;} this.ID.scrollLeft -= this.Step; } break; } } </SCRIPT> (2)这段代码放到文章列表的下面: <SCRIPT>new srcMarquee("ScrollMe",0,1,808,43,10,3000,3000,43)</SCRIPT> 现在你在织梦dedecms后台添加文章,选中滚动属性‘s’ ,你的文章列表就应该滚动起来了。 (责任编辑:好模板) |
