javascript下过滤数组重复值的代码

<script language="javascript">

function getNoRepeat() {

return arguments[0].join('‖').match(/(\b[^‖]+\b)(?!.*‖\1\b)/ig);

}

var tmpArr = [1, 'a', 'ab', 'abc', 'd', 1.2, 'a+b', 'd', 'e', 5, 'a', 1, 'h', 'c', 'ab'];

var retArr = getNoRepeat(tmpArr);

alert(retArr);

</script>
