<script type="text/javascript">
var myarrs=new Array(80,90,60,20,50,69,57,100,58,36)
for(var num=1; num<myarrs.length; num++){
if(num<60){
{continue;}
}
document.write("数值"+myarrs[num]+"<br>")
}
</script>
if(num<60){ 应该是if(myarrs[num]<60)
还应该把初始条件改成numb=0,因为数组的第一个索引为0
将if(num<60)改成if(Array[num]<60)试试
