本文實例講述了js實現(xiàn)精美的圖片跟隨鼠標效果實現(xiàn)方法。分享給大家供大家參考。具體實現(xiàn)方法如下：
<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>精美js鼠標跟隨代碼</title></head><body><script> A=document.getElementByIdB=document.all;C=document.layers;T1=new Array("trail1.gif",38,35,"trail2.gif",30,31,"trail3.gif",28,26,"trail4.gif",22,21,"trail5.gif",16,16,"trail6.gif",10,10)var offsetx=15 var offsety=10nos=parseInt(T1.length/3)rate=50ie5fix1=0;ie5fix2=0;rightedge=B? document.body.clientWidth-T1[1] : window.innerWidth-T1[1]-20bottomedge=B? document.body.scrollTop+document.body.clientHeight-T1[2] : window.pageYOffset+window.innerHeight-T1[2]for (i=0;i<nos;i++){createContainer("CUR"+i,i*10,i*10,i*3+1,i*3+2,"","<img src='"+T1[i*3]+"' width="+T1[(i*3+1)]+" height="+T1[(i*3+2)]+"border=0>")}function createContainer(N,Xp,Yp,W,H,At,HT,Op,St){with (document){write((!A && !B) ?
