1、数组转字符串
需要将数组元素用某个字符连接成字符串,示例代码如下:var a, b;a = new Array(0,1,2,3,4);b = a.join("-"); //"0-1-2-3-4"
2、字符串转数组
实现方法为将字符串按某个字符切割成若干个字符串,并以数组形式返回,示例代码如下:
var s = "abc,abcd,aaa";ss = s.split(",");// 在每个逗号(,)处进行分解 ["abc", "abcd", "aaa"]var s1 = "helloworld";ss1 = s1.split(''); //["h", "e", "l", "l", "o", "w", "o", "r", "l", "d"]
