删除数组的重复元素

给出数组，判断重复元素，出现重复元素，修改数组删除元素，主要代码

<script type="text/javascript">
var array=new Array("name","name2","name2","name2","name2","name1","name1","name1","name2","name7","name8","name7");
for(var i=0;i<array.length;i++){
for(var j=i+1;j<array.length;j++){
if(array[i]==array[j]){
array.splice(j,1);//<span style="font-family: Arial, Helvetica, sans-serif;">修改数组删除元素</span>

j--;
}
}
}
alert(array.join(","));//数组以字符串输出
</script>
