JS数组转字符串和字符串转数组

主要用到以下两个函数

join();//将数组转换成字符串
split();//将字符串转换成数组

    <script type="text/javascript">
        var a = new Array("afdas","bdfa","cd","sfdsd","fdsae");
        var b = a.join("+");//转换成字符串用+隔开
        document.write(b);

        document.write("<br>");
        var c = b.split("+");// 在每个+处进行分解,组成新的数组
        document.write(c);
    </script>
