<script type="text/javascript">
//最简,测试过是OK的,
var j=10;
document.write('<span class="no" id="n'+Math.floor(Math.random() * j)+'">b</span>');
document.write('<span class="no" id="n'+Math.floor(Math.random() * j)+'">b</span>');
document.write('<span class="no" id="n'+Math.floor(Math.random() * j)+'">b</span>');
//或按照你的方法,测试过是OK的,
b = new Array('n1','n2','n3','n4','n5','n6','n7','n8','n9','n10')
document.write('<span class="no" id="'+b[Math.floor(Math.random() * b.length)]+'">a</span>');
document.write('<span class="no" id="'+b[Math.floor(Math.random() * b.length)]+'">a</span>');
