用JavaScript实现上下文字滚动特效
作者:佚名 转贴自:本站原创 点击数:2273
中国重庆vi设计在线推荐:用javascript实现上下文字滚动特效 文字左右滚动的走马灯效果是一种非常容易实现的特效,同样的,文字上下滚动循环显示也是一种非常常见而且非常容易实现的文字特效。
具体实现方法如下:
<script language=javascript> var messages=new Array() messages[0]=<font color=#8000FF>欢迎光临赛迪网电脑应用频道!</font></a> messages[1]=<font color=#FB2500>这里有织网梦工厂</font></a> messages[2]=<font color=#FF0066F>是网页初学者的学习园地</font></a> messages[3]=<font color=#FF9900>这里冲浪指南针</font></a> messages[4]=<font color=#00CC33>是网络爱好者天天必来充电的地方</font></a> messages[5]=<font color=#000000>这里有…………有精彩的内容等着你</font></a>
var scrollerwidth=320 var scrollerheight=100 var scrollerbgcolor=''#FFFFFF'' //下面的代码不要改动 if (messages.length>1) i=2 else i=0 function move1(whichlayer){ tlayer=eval(whichlayer) if (tlayer.top>0&&tlayer.top<=5){ tlayer.top=0 setTimeout(move1(tlayer),3000) setTimeout(move2(document.main.document.second),3000) return} if (tlayer.top>=tlayer.document.height*-1){ tlayer.top-=5 setTimeout(move1(tlayer),100)} else{ tlayer.top=scrollerheight tlayer.document.write(messages[i]) tlayer.document.close() if (i==messages.length-1) i=0 else i++}} function move2(whichlayer){ tlayer2=eval(whichlayer) if (tlayer2.top>0&&tlayer2.top<=5){ tlayer2.top=0 setTimeout(move2(tlayer2),3000) setTimeout(move1(document.main.document.first),3000) return} if (tlayer2.top>=tlayer2.document.height*-1){ tlayer2.top-=5 setTimeout(move2(tlayer2),100)} else{ tlayer2.top=scrollerheight tlayer2.document.write(messages[i]) tlayer2.document.close() if (i==messages.length-1) i=0 else i++}} function move3(whichdiv){ tdiv=eval(whichdiv) if (tdiv.style.pixelTop>0&&tdiv.style.pixelTop<=5){ tdiv.style.pixelTop=0 setTimeout(move3(tdiv),3000) setTimeout(move4(second2),3000) return} if (tdiv.style.pixelTop>=tdiv.offsetHeight*-1){ tdiv.style.pixelTop-=5 setTimeout(move3(tdiv),100)} else{ tdiv.style.pixelTop=scrollerheight tdiv.innerHTML=messages[i] if (i==messages.length-1) i=0 else i++}} function move4(whichdiv){ tdiv2=eval(whichdiv) if (tdiv2.style.pixelTop>0&&tdiv2.style.pixelTop<=5){ tdiv2.style.pixelTop=0 setTimeout(move4(tdiv2),3000) setTimeout(move3(first2),3000) return} if (tdiv2.style.pixelTop>=tdiv2.offsetHeight*-1){ tdiv2.style.pixelTop-=5 setTimeout(move4(second2),100)} else{ tdiv2.style.pixelTop=scrollerheight tdiv2.innerHTML=messages[i] if (i==messages.length-1) i=0 else i++}} function startscroll(){ if (document.all){ move3(first2) second2.style.top=scrollerheight} else if (document.layers){ move1(document.main.document.first) document.main.document.second.top=scrollerheight+5 document.main.document.second.visibility=''show''}} window.onload=startscroll </script> <ilayer id=main width=&{scrollerwidth}; height=&{scrollerheight}; bgcolor=&{scrollerbgcolor};> <layer id=first left=0 top=1 width=&{scrollerwidth};> <script language=javascript1.2> if (document.layers) document.write(messages[0]) </script> </layer> <layer id=second left=0 top=0 width=&{scrollerwidth}; visibility=hide> <script language=javascript1.2> if (document.layers) document.write(messages[1]) </script> </layer> </ilayer> <script language=javascript1.2> if (document.all){ document.writeln(''<span id=main2 style=position:relative;width:''+scrollerwidth+'';height:'' +scrollerheight+'';overflow:hiden;background-color:''+scrollerbgcolor+''>'') document.writeln(''<div style=position:absolute;width:''+scrollerwidth+'';height:'' +scrollerheight+'';clip:rect(0 ''+scrollerwidth+'' '' +scrollerheight+'' 0);left:0;top:0>'') document.writeln(''<div id=first2 style=position:absolute;width:''+scrollerwidth+'';left:0;top:1;>'') document.write(messages[0]) document.writeln(''</div>'') document.writeln(''<div id=second2 style=position:absolute;width:''+scrollerwidth+'';left:0;top:0>'') document.write(messages[1]) document.writeln(''</div>'') document.writeln(''</div>'') document.writeln(''</span>'') } </script>
(在需要添加该特效的网页具体位置中粘贴如下代码即可)
注意:代码中的“var scrollerwidth=320”表示循环框宽度,var scrollerheigh=100表示循环框高度,font color=# 代表文字颜色,可以根据需要进行修改。 |
