js实现字符串和数组相互转换

<div class="aa"></div>
<script>
    //字符串转换为数组
    var Str="abc-mng-zhang-mayi";
    var newArray=Str.split("-");
    $(".aa").text("abc-mng-zhang-mayi 转换 newArray[0]:"+newArray[0]);
</script>

<div class="bb"></div>
<script>
    //将数组转换为字符串
    var newArray2=["abc","mng","zhang","mayi"];
    var Str=newArray2.join("-");
    $(".bb").text("newArray2 数组转换字符串:"+Str);
</script>
