代码提示:按下面的说明修改并复制代码
第一步:把如下代码加入<body>区域中 <STYLE> .spanstyle { LEFT: -5000px; POSITION: absolute } </STYLE> <SCRIPT> <!-- Beginning of JavaScript - // 修改图像的高度、宽度和地址 var imgwidth=200 var imgheight=110 var imgurl=new Array() imgurl[0]="photo/a048.gif" imgurl[1]="photo/a049.gif" imgurl[2]="photo/a052.gif" // Do not edit this block. var imgpreload=new Array() for (i=0;i<=imgurl.length-1;i++) { imgpreload[i]=new Image() imgpreload[i].src=imgurl[i] } // Final horizontal position of the image: distance to the left margin of the window var x_finalpos=300 // Final vertical position of the image: distance to the top margin of the window var y_finalpos=110 // Number of sliced cells (the higher this value the slower the script) var x_slices=8 // Number of sliced rows (the higher this value the slower the script) var y_slices=3 // Speed of the reassembling effect.
