font-size: 14px;color:#000000;color:#ff5959;line-height: 30px;margin-left: 5px;}

#clickme{width: 120px;height: 25px;margin-top: 5px;margin-left: 20px;}
</style>
<div class="center">
<div id="tone0" class="tone"></div>
<div id="tone1" class="tone"></div>
<div id="tone2" class="tone"></div>
<div id="tone3" class="tone"></div>
<div id="tone4" class="tone"></div>
<div id="tone5" class="tone"></div>
<div id="tone6" class="tone"></div>
</div>

<button type="button" id="clickme" onclick="run()">点我生成双色球</button>

<script type="text/javascript">
function run(){
var reds=[parseInt(Math.random()*32+1)];
var blues=parseInt(Math.random()*15+1);

while(reds.length<6){
var r=parseInt(Math.random()*32);
//循环遍历reds数组
for(var i=0;i<reds.length;i++){
if(reds[i]==r){
break;
}else if(i==reds.length-1){
reds.push(r);
//console.log(reds);
}
}
}
for(var j=0;j<reds.length;j++){
document.getElementById("tone"+j+'').innerHTML=reds[j];
}
document.getElementById("tone6").innerHTML=blues;
}
run();
</script>

效果如下：
