如题，我智商捉急，实在想不出神马方法 var col=new Array("#F00","#3C6","#F39","#09F"); function color() { document.getElementById("logo").style.borderTopColor=col[0]; document.getElementById("logo").style.borderRightColor=col[1]; document.getElementById("logo").style.borderBottomColor=col[2]; document.getElementById("logo").style.borderLeftColor=col[3]; setInterval("color1()",500); } function color1() { document.getElementById("logo").style.borderTopColor=col[1]; document.getElementById("logo").style.borderRightColor=col[2]; document.getElementById("logo").style.borderBottomColor=col[3]; document.getElementById("logo").style.borderLeftColor=col[0]; setInterval("color2()",500); } function color2() { document.getElementById("logo").style.borderTopColor=col[2]; document.getElementById("logo").style.borderRightColor=col[3]; document.getElementById("logo").style.borderBottomColor=col[0]; document.getElementById("logo").style.borderLeftColor=col[1]; setInterval("color3()",500); } function color3() { document.getElementById("logo").style.borderTopColor=col[3]; document.getElementById("logo").style.borderRightColor=col[0]; document.getElementById("logo").style.borderBottomColor=col[1]; document.getElementById("logo").style.borderLeftColor=col[2]; setInterval("color()",500); }
