急！急！ js中产生不一样的随机数！
如1-30之间，我想产生10个随机整数，但这10个（或15个）个数必须不一样，求高手解答~
[解决办法]
<script type="text/javascript">
var r=parseInt(Math.random()*30);
var array=[];
for(var i=0;i<11;i++)
{
var flag=0;
do
{
for(var j=0;j<array.length;j++)
{
if(array[j]==r) {flag=1;break;}
}
if(!flag)
{
array[array.length]=r;
}
else
{
r=parseInt(Math.random()*30);
}
}while(!flag);
}
for(var j=0;j<array.length;j++)
document.write(array[j]+" ");
</script>
